August 29, 2019 TO: Mayor and City Council FROM: David Torgler, City Manager RE: Proposals to Redevelop the City’s ML&P Power Plant

Background:

In May the City Council authorized the release of a Request for Proposal (RFP) for sale and redevelopment of the City’s Municipal Light and Power (ML&P) power plant located at 1133 Main Street. RFP’s were released on May 29th. A mandatory facility tour was provided for individuals and interested parties on June 12th. Proposals were due on Wednesday, August 21st. Attached are three (3) proposals that were received with one proposal being ineligible due to non- participation in the mandatory facility tour, not providing the proposal electronically to the City Clerk as required, and because it is non-responsive to Proposal Requirements. Summary reviews of the proposals were prepared by staff and are also attached.

Per the RFP City officials will evaluate proposals based on the following criteria which are not listed in any preferred order:

1. Relevant experience of the proposal team. 2. Alignment of the proposed project with the City’s goals: e.g. how do you propose to redevelop the ML&P site to help POWER downtown revitalization, SPARK innovation and creativity, PRESERVE historical character of the site in some fashion, and GENERATE sustainable new jobs. A successful proposal will address all four of these goals. 3. Track record of proven success on development projects of a similar nature. 4. Ability of the proposal team to bring unique partnerships and resources to the table. 5. Project schedule

The City of Delta can accept or reject any or all proposals at their sole discretion. City officials and their representatives can negotiate with firms submitting proposals at their sole discretion.

Cost to City:

A relocation or consolidation of ML&P facilities is required as part of any redevelopment of the 1133 Main Street property. Other costs may be agreed to by the City Council through negotiations with the selected developer.

Alignment with Strategic Plan:

A Core Priority of the 2018 Strategic Plan is to keep and improve the quality of life. Specifically one of the City Council’s objectives in this plan is to sell underutilized City facilities. In November 2018 the City’s voters approved the Council’s ability to sell the ML&P site for not less than $100,000.

Recommendation:

The developer(s) of the selected proposal will be invited to finalize a project plan for the redevelopment of the ML&P power plant site. If no proposal is acceptable then the Council can direct staff to reissue the RFP with any changes they choose to make.

Request for Proposals

The City of Delta is seeking responses to this request for proposals (RFP) from developers, investors, entrepreneurs and other parties interested in redeveloping the City’s Municipal Light and Power (ML&P) power plant located on Main Street at the southern entrance to the City’s downtown core. The property address is 1133 Main Street. City officials are interested in working with the private sector to repurpose this landmark site into something as valuable to the community as the generation of electricity was in the past to Delta.

City of Delta Goals

The City envisions the ML&P power plant repurposing as both a catalyst for downtown revitalization, and a critical anchor to the City’s downtown core. This site is rich in history, having generated electricity for City residents since 1937. Responders to this request for proposals will describe how they will redevelop the ML&P site to help POWER downtown revitalization, SPARK innovation and creativity, PRESERVE historical character of the site in some fashion, and GENERATE sustainable new jobs. A successful proposal will address all four of these goals.

About the Building and Land

The facilities are currently used to house ML&P maintenance and operation functions including staff, equipment and vehicles. These functions will be relocated as part of any sale and redevelopment and need to be considered in the project timing. The original power plant was constructed in 1937. Several additions and remodels have occurred over the years to accommodate the changing needs of the City’s electric power generation. The main building includes an engine room where seven iron and steel engines powered the city’s electrical grid. The power generating engines were operated until May 2014 when the City had to retire the engines due to clean air quality emission regulations. The City determined at that time that retrofitting the engines was cost prohibitive and instead began purchasing all of its power needs from a wholesale power supplier. Total square footage of the building is approximately 12,200. In 2017 a broadband Carrier Neutral Location, or CNL, was constructed at this location, so broadband service is easily accessible. The CNL is a small footprint that will remain with the City as part of any sale and site redevelopment with access to these facilities being restricted and through an existing exterior door. Fiber and electric infrastructure exist beneath the facility floor and alley Right-of-Way which must remain intact. The City is planning on re-purposing the 5000 gallon fuel tank and removing it from the site. While a building drawing is included with these RPF materials a tour of the building is absolutely necessary to understand the building opportunities and take in the history. A mandatory pre-proposal conference and site inspection will be conducted when potential proposers will have the opportunity to observe actual conditions and verify site information, see process schedule. Adjacent to the redevelopment site is an electrical substation that is not part of the redevelopment.

Proposal from: Mainspring

Does the Proposal:

Repurpose facility into something as valuable to the community? Yes Proposal Introduction/Summary: Culinary arts and businesses take center stage in the repositioned Delta ML&P building which taps into the renaissance in craft food production in the US. The Roots project, at its core, is a business development initiative, rooted in the deep agricultural traditions of Delta County, located in an underutilized asset and tapping into the growing pains experienced by start-ups in the Front Range.

Delta has an opportunity to mobilize to create unique affordable spaces and to tap into location-neutral entrepreneurs who are looking for alternative locations to live and establish businesses, as the main urban hubs become increasingly cost prohibitive. Colorado is known for its high-quality produce, and the craft small batch food production scene is on a strong trajectory; however, Denver and the front range in general is increasingly unaffordable for these entrepreneurs. By creating an incubator/food hub with affordable space and supportive services, the community will attract small culinary businesses looking for an opportunity to establish and grow in an affordable and supportive environment. This hub will establish Delta as a premiere destination for food focused start-up businesses and events highlighting the regional produce of the Western Slope. This carefully crafted hub will advance the local economy through business expansion and job creation, putting Delta on the map as the “it” place for creatives and visitors alike and catalyzing further growth and opportunities.

The re-envisioned building will be a catalytic investment in Delta improving the street appeal of the south end of Main Street with a combination of open to the public spaces and work spaces for incubated businesses. The Roots project will revitalize and reposition the Delta ML&P site to serve as a transformative project to downtown Delta, while serving as a community asset for local residents to come together in event and garden spaces available for a variety of programs and events.

Key goals: (1) enhance and beautify the Main Street frontage to slow down traffic, draw people in and provide Main Street energy (2) provide a space for the local community to gather, hold events and community engagement (3) create an entrepreneurial zone for small businesses to establish, root in the community and grow

Proposal from: Hobbs Industries, Inc.

Does the Proposal:

Repurpose facility into something as valuable to the community?

Proposal Introduction/Summary: To redevelop and repower the City’s ML&P Power Plant(the “Plant”), using the most efficient technology on the market today, to create a modern and highly efficient Combined Heat & Power (“CHP”) plant, with supporting solar + storage capacity, as a catalyst for downtown revitalization and for meeting growing power supply and redundancy needs.

Our proposal is focused on the repowering and upgrading of the Plant and interconnecting with the City’s Palmer Substation and distribution system. General idea being to remove the old inefficient Fairbanks Morse units, upgrading the foundations, and installing new highly efficient and compact RICE units.

We believe the Plant is well positioned for helping wholesale power suppliers serve growing local demand while making beneficial use of waste-heat to provide the heating and cooling needs of downtown area businesses and commercial operations on a cost savings bases.

CHP is far more energy efficient than traditional power generation technologies and why treated like renewable resources by federal agencies and encouraged by most states. We also propose adding and integrating solar + storage capacity to further increase efficiencies, improve operational flexibility, and reduce costs.

The project consists of a land swap with the local council, whereby the owner of a Mitre 10 (big box hardware similar to Home Depot) moves off main street to a council owned site and MAINSPRING takes possession of the existing main street site for an adaptive re-use project to help beautify main street, revitalize the small town (Huonville is the hardworking municipal seat in an agricultural and culinary creative valley), provide opportunities for small businesses, act as the gateway for the food and wine trail, provide community space and develop a boutique hotel.

Food & Beverage: • Blue Sparrow Coffee – opened 2017 www.bluesparrowcoffee.com • Room for Milly (opening November 2019) • Queen’s Eleven (opening September 2019)

ENGAGE

In Agriculture:

● Was an active member of the steering committee for the Food, Farm Forum in 2018 and is again on the steering committee for 2019. ENGAGE sponsored four speakers for the 2018 conference and hosted talks centered on creating a Food Hub for the Western Slope. ● Stood up a food incubator in Paonia at Edesia Community kitchen and sister kitchens in Delta, Cedaredge and Crawford to support Edesia and food entrepreneurs.

● Purchased over $20K worth of portable food processing equipment to support local food entrepreneurs. Equipment is also available to the public for rent at Edesia or can be delivered to their production site. ● In the past 18 months has supported 34 local businesses in a variety of capacities from back end business support, equipment rental, licensing, financing, grant writing, networking, marketing, distribution, education and locating affordable space. ● ENGAGE has also built a strong network of partners over the past 18 months including o Telluride Venture Accelerator o StartUp Colorado (SUCO) o Guidestone’s Land Link o Naturally Boulder o GJ Incubator o Icelab o MENV o CSU food economist’s Becca Jablonski & Dawn Thilminay o Colorado Great Outdoors o Many other local and regional business professionals ● ENGAGE just completed a business challenge where 15 companies were selected to compete for $11K in verifiable business expenses. All participants completed a business class, pitch preparation and cohort networking events over a three-month period. Winners were chosen by a panel of local professionals judging their business plan, pitch and community alignment. ● ENGAGE is currently working with a variety of local organizations to build a “food corridor” on the Western Slope that contains the country’s first “Creative Culinary District” similar to the certified Arts Districts across the nation. This “connecting the dots” in our rich food and Ag culture will draw interest, investment and tourism to our county. The Food Corridor may include IQF (individual quick freeze), co-packing, large scale food aggregation, food storage, food processing, an accelerator and developing a regional brand and marketing plan. ● ENGAGE has also participated in a “farm to school” program to study how to grow more food on school grounds and get more local produce into the school district. ● ENGAGE has also begun talks with local developers about Agri-Hoods which could be part of the solution for “succession planning” for a section of the farming community that does not have a plan for their agricultural land. It is a way to

intentionally attract people who have an interest in agriculture but might not have the skill set or time to be a full-time farmer. Think of a golf course development with a farm instead of a golf course. SECTION 3: PROJECT PROPOSAL

1. Outline of the type of project you are interested in pursuing (restaurant, retail, mixed use, housing, industrial, research & development, tourism as examples).

Culinary arts and businesses take center stage in the repositioned Delta ML&P building which taps into the renaissance in craft food production in the US. The Roots project, at its core, is a business development initiative, rooted in the deep agricultural traditions of Delta County, located in an underutilized asset and tapping into the growing pains experienced by start-ups in the Front Range.

This hub will establish Delta as a premiere destination for food focused start-up businesses and events highlighting the regional produce of the Western Sope. This carefully crafted hub will advance the local economy through business expansion and job creation, putting Delta on the map as the “it” place for creatives and visitors alike and catalyzing further growth and opportunities.

(4) attract out of town/area visitors and provide activities and options to spend time and money in Delta (5) provide a gateway to the food, wine and produce of greater Delta County

We have conceptualized this revitalization project as returning to and honoring the roots of Delta and Delta County, in its hardworking, agricultural, manufacturing origins. Our goal is to build on those roots and introduce new food-based production and craft batch manufacturing to Delta. The core of the Roots project will be a fully equipped commercial production kitchen, with a series of programs that attract and retain entrepreneurs and small businesses in the craft food production industry. Additional elements will include a tasting room fronting Main Street, featuring the vast array of beverages and food being produced in Delta County along with new items being developed in the Roots production kitchen. Alongside will be an outdoor patio, allowing visitors to enjoy food and beverages outdoors under twinkling patio lights adjacent to Main Street. Both the tasting room and the patio will be highly visible to any passing traffic on Main Street, activating this part of downtown and enticing individuals to stop. Surrounding these elements will be a large community/event space, a community garden, and a smaller chef’s kitchen and kitchen garden.

The programmatic plan for the site:

Programming in Detail:

Main Street Tasting Room: The Main Street tasting room will serve as an introduction to visitors to Delta County’s wonderful produce and increasing food production, from locally grown and produced wine, spirits, ciders, and juices to food products such as cheeses, cured meats, dried fruits, and freshly harvested seasonal produce. It will provide an interesting stop for visitors and a meeting and gathering point for locals, with an airy revived industrial interior highlighting the architecture of the building with original brick walls, exposed steel and light pouring through the huge preserved MP&L steel windows. In addition to prepared and served food and beverages, a commissary market will sell locally produced items. MAINSPRING would look to partner with local operators (such as Sam Kimbriel or Lance Hanson) to operate the tasting room space to provide an authentic Delta welcome.

Main Street Patio/Garden: The large industrial doors on the north side of the building will open to the patio/garden. Guests will be welcomed to enjoy their food and beverages outside on the patio under the shade of existing and newly established shade trees, surrounded by a beautiful garden and under twinkling patio lights in the evening, with a fire roaring in the fireplace made of repurposed boilers on colder evenings.

Community/Event Space: In the rear of the tasting room, windows will reveal (and a door will lead to) the large community/event space. As in the tasting room, this space will highlight the industrial heritage of the building, with exposed brick, steel trusses and girders and the huge arched steel window at the rear of the building. At the north end of the space, large windows will reveal the production kitchen so that visitors may observe activities and production occurring at any time. This community space will provide a comfortable and inviting location for local groups to rent for private events or for local community organizations or non-profit groups to utilize at no cost for community events and activities. This space will also serve as an ideal teaching and educational environment for the programs deployed out of the Roots complex.

Production Kitchen: The Production kitchen will be a fully equipped and licensed commissary kitchen. It will be made available on a long term basis to a new 501c(3) organization established with seed funding from MAINSPRING to provide the long term programming and operation of the space and will serve as the hub of the entire complex, with ENGAGE serving as the thought and resource partner on the programming out of this space, and over time will dial in the most impactful programming. Current programs envisioned are:

1. Food Production Industry Boot Camps – These short programs will attract food industry entrepreneurs for short periods of time to programs that focus on unique aspects of the food production business, ranging from business-oriented programs to hands on production programs. They are a low-pressure way to attract and interact with a large volume of entrepreneurs that could potentially relocate, launch or expand to Delta. These boot camps could include both thematic and functional programs:

a. Thematic- Short intensive boot camps focused on developing innovations to address challenges facing food businesses and the regional food economy such as: i. Innovative packaging ii. Distribution systems (digital platforms for producers, buyers, distributors) iii. Sourcing locally year round iv. Creating and building local market channels v. Developing food products for regional market channels vi. Community education on local food

b. Functional- Short intensive boot camps around business, leadership, funding and startup support for: i. F2TE (farm to table experience) ii. VAFM (value added food manufacturing) iii. VABM (value added beverage manufacturing)

2. Business in Residence – Individual food production businesses may apply or may be invited to locate their business in the Production kitchen for a period of time ranging from a few months to potentially up to 24 months. This program is inspired by the well-known artist in residence programs. During this time the business (or culinary “artist”) in residence will have

access to the licensed kitchen and equipment to advance their business idea and will be fully supported by resources needed to develop and grow their business. Resources could include: a. Business Blueprint Course (10 weeks) Small Business Development Center b. Mentorship and consulting c. Cohort networking d. Access to capital e. Specific food business training i. Identifying your market ii. Packaging iii. Distribution systems (digital platforms for producers, buyers, distributors) iv. Sourcing locally year round v. Creating and building local market channels vi. Developing food products for regional market channels

3. Food Production Business Incubator – Following on from the business in residence program, select businesses will be invited to the incubator program. This program will invest capital in the fledgling business and allow the business to continue in the Production kitchen for a further period to attain sustainability and commercial success for their product.

Restaurant/Chef’s Garden: The smaller building to the south of the main MP&L building will be renovated into a chef’s kitchen. It will be a smaller space intended for restaurant use, with visiting chefs and potentially a chef in residence. It will open to a chef’s garden, growing herbs and vegetables for use in the restaurant, with long tables set in the garden for dinners throughout the harvest season. Guest chefs will be invited to prepare dinners highlighting Delta produce and ticketed long table dinners will be held to attract Front Range and visiting foodies and gourmands to experience the fresh bounty of the region in the hands of some of the country’s most talented chefs. Roots will partner with the Colorado Tourism Office and agri-tourism leaders to promote and highlight these dinners.

Community Garden: Adjacent to the chef’s restaurant will be a community garden. This garden will serve the Production kitchen and provide a learning and teaching environment for students and residents in the Production kitchen along with local elementary school groups and other groups interested in understanding the complexities of healthy locally grown food. Residents of the Production kitchen will have primary responsibility for the cultivation of the community garden.

Parking: Parking will be located at the existing rear of the MP&L building and a new entrance will be designed.

2. An overview of how you propose to work with the City and its partners to repurpose this site.

Environmental. The MP&L building and site will require extensive environmental review and remediation, working closely with local, state and potentially federal departments. There is an established history of use of toxic to human health substances and non-fully remediated contamination, along with existing lead paint and asbestos. In addition, the generators and machinery used by the MP&L organization that are still on site will need to be removed from the building.

This environmental assessment and remediation is far larger than any private company can undertake and fund, as the financial productivity of the building (even if used in the most commercially profitable context, which this new use will not be) cannot remotely provide the return that would be needed to justify the capital cost required to remediate a former industrial electrical production facility to being fit for high use let alone for food production. Without the results of a full environmental assessment and based only on a visual assessment and oral information from the plant administration, MAINSPRING believes that remediation is easily in the $1-2 million range.

There is a significant amount of grant money available at the State and federal levels to support the necessary assessments and remediation of the site. However, many of these resources are only available to municipalities. As a result, we propose a structure whereby the City of Delta retains ownership of the MP&L site throughout the environmental assessment and remediation process. MAINSPRING will leverage its resources and assist the City, working as the project manager to corral the resources necessary to achieve remediation of this site. Upon conclusion of remediation the MP&L site would be transferred to MAINSPRING.

Site Visioning. If selected, MAINSPRING will meet with Council and Council staff to refine the vision for the MP&L building and incorporate feedback and concerns. MAINSPRING will also hold public meetings to preview the vision above and programming for the site with the community, in order to receive and accommodate public input.

Housing. If successful, this project will create a need for short term accommodation and longer-term or permanent housing. Individuals attending boot camps, visiting Roots, and attending long table diners will need hotel and short stay accommodation.

8. Other information that helps City officials understand and assess how your vision and the City’s vision align.

The food production industry is going through a small manufacturing renaissance, with small batch products being developed by entrepreneurial start-ups. Consumers are increasingly seeking out high quality, small batch gourmet food products, with markets and supermarkets providing dedicated shelf space to small production and local items (e.g. Marczyk and Whole Foods.)

However, food production is a capital-intensive manufacturing undertaking, needing dedicated facilities, unique equipment and licensed commercial kitchens to sell products in supermarkets and to restaurants. Access to affordable commissary kitchens in urban areas is becoming highly constrained, and it is becoming prohibitively expensive for small start-ups to acquire or lease space necessary to set up production kitchens. By providing fully equipped licensed kitchen space at free or very affordable rates, agricultural regions such as Delta may be able to attract this new wave of food manufacturing. While logistics are more complicated in rural areas, they are not insurmountable. For example, food production items focused on locally grown produce significantly reduces the transportation cost of the raw/fresh item into the production facility, while the final product to be shipped out is a more compact end product taking less shipping space.

To access wealth and additional well-paid jobs, rural agricultural areas need value added production to remain in their region. Rather than shipping out all the fresh seasonal produce, if a portion can be retained in region and turned into a gourmet produced item, it stabilizes the shelf life and creates value added products to enhance the local communities’ financial health. The best example of this ideal closed circle of food production may be Modena, one of the most productive growing regions in Italy (as Delta County is in Colorado) and also one of the wealthiest. Its grapes are produced into not just wine but also the world’s best balsamic vinegar, its pork is not just eaten fresh but turned into the world’s best parma ham and prosciutto, its dairy farms provide the milk for the world’s best Parmiggiano Reggiano. Modena is home to culinary creatives both multi-generational and new, such as the number one restaurant in the world – Osteria Francescana– and with a megaphone the products of Modena are showcased to the world by Massimo Bottura.

Food grown and produced in Colorado enjoys a high reputation elsewhere in the U.S. and is viewed favorably as healthier and higher quality. The City of Denver created a unique program with its Cottage Food Act which boosted the ability of entrepreneurs in the food space to start and test concepts. Food produced in a non-licensed kitchen can be sold at farmers markets, providing an opportunity to test concepts. However, to get to the next level and be sold on supermarket shelves and thereby create a sustainable company and associated jobs, these entrepreneurs must move to a commercial commissary or licensed kitchen. This is a huge step for a small start-up. To build their own space requires a huge amount of capital and to lease space in a commissary kitchen on the

Front Range is prohibitively expensive. These small start-ups are the target for the Roots programs, by providing free or cheap kitchen space, wrap around supportive resources, and the potential for a capital investment through the Roots Investment Fund. Imagine if Delta County can harness a small fraction of the wealth that is ultimately created by its current bounty of fresh produce currently being shipped out of the region.

Small businesses need significant support, resources and capital in order to succeed. By setting the program up under the Roots 501c(3), we will have access to philanthropic foundation capital to both purchase equipment and run the Roots programming. We know that these foundations are extremely interested in assisting rural job creation, among other things, and this Roots program provides an ideal opportunity for that funding.

Dear Mr. Torgler:

We are writing to express our support for Mainspring’s Roots project, planned as part of the repurposing of the Delta Municipal Light and Power (ML&P) plant. We’re newer residents of Delta County and are launching a farm-to-kitchen cooking school here. We were excited to learn of Mainspring’s plans to invest in Delta through the Roots project; we see this as an excellent opportunity to support not only our efforts but others like us who are also interested in expanding the local food and beverage ecosystem.

The Roots project aligns well with existing local efforts and will spark innovation by supporting innovative product development. We were also pleased to learn that the Roots project will repurpose the site in a manner consistent with Delta’s food production history. With agriculture serving as the backbone of Delta County plus a community desire to spur economic development activity, this project feels like the perfect combination of these two driving forces.

We believe that Roots will provide significant value to the Delta community as a whole – from serving as a space for the community to gather to enhancing tourists’ visits by providing them with a place to experience all that Delta County has to offer. The Roots project has the potential to truly showcase the agricultural beauty of Delta County and to catalyze the town’s growth by attracting small businesses to root and grow here. We believe the Roots project has genuine potential to create a brand for Delta and to earn name recognition in western Colorado and beyond. For these reasons, we are thrilled to provide our support for the Roots project.

Sincerely,

Elizabeth and Nicholas Buckingham Quiet Farm Cedaredge, CO findingquietfarm.com

Mr. David Torgler 360 Main Street Delta, CO 81416

Dear Mr. Torgler,

I am writing to express my strong support for the Mainspring Roots project planned as part of the repurposing of the Delta Municipal Light and Power (ML&P) power plant. As superintendent of Delta County Schools, I was excited to learn of the City’s plans to repurpose the ML&P power plant and to use the site as a catalyst for downtown revitalization.

I believe that the Roots project will preserve the historic character of ML&P while revitalizing the site with innovative community efforts and generating economic growth. This project is unique in that it highlights Delta’s food production and manufacturing roots, leveraging people’s growing interest in understanding where their food originates. An integral part of Roots is its alignment with existing local efforts to not only advance the local food and beverage ecosystem but to spark innovation by developing new opportunities to support product development. Given this alignment, the project has the capacity to feature local growers and producers in the space and to promote these businesses outside of Delta.

One of the most important reasons why I support the Roots project is that it will provide significant value to the Delta community as a whole – from students who will have a fun and creative space to learn about local food production and participate in the community gardens, to residents who will enjoy new, sustainable job opportunities and a place to support local businesses. Roots has the potential to showcase the beauty of Delta and to catalyze our town’s growth by attracting small businesses to root and grow here. I believe the Roots project has genuine potential to create a brand for Delta and to earn name recognition in rural Colorado and beyond.

Because the Roots project will revitalize downtown, create job opportunities, inspire community ingenuity, and preserve the character of the ML&P power plant, I am pleased to provide my support to the Roots project to launch at 1133 Main Street. I look forward to seeing how the Roots project will support the community and transform Delta.

HOBBS Industries, Inc Proposal for Repowering Delta’s ML&P Power Plant

Work History 2015 - Present: As a participant and consultant to UAF, I’ve been instrumental in identifying how coal gasification might be used to repurpose the soon to be decommissioned CHP at UAF to drive an existing diesel engine generator to help Golden Valley Electric Association (“GVEA”) regulate wind resources while complimenting operations of its new CHP plant. 1985 - Present: As the founder, I directed Hobbs Industries to pursue opportunities in the design, manufacture and installation of power generation equipment and systems. I expanded this business to include both general and electrical construction that was largely power generation related. I’ve designed, manufactured and installed many power generation systems for Pacific Northwest and Alaska customers that included the State of Washington, City of Seattle, Boeing, US Coast Guard, Alaska Department of Transportation, Alaska villages and numerous mining and construction companies. I further expanded the business to include the development of several energy and power generation projects. 1975 - 1984: Employed by large western coal-mining companies in capacities of Chief Electrician, Electrical Engineer, Maintenance Manager, and Project Manager. In most cases, I was responsible for directing the design and construction as well as maintenance needs of large mining operations that frequently included power generation.

HOBBS Industries, Inc Proposal for Repowering Delta’s ML&P Power Plant

3. Proposal Includes: a. Project Outline Our proposal is focused on the repowering and upgrading of the Plant and interconnecting with the City’s Palmer Substation and distribution system. General idea being to remove the old inefficient Fairbanks Morse units, upgrading the foundations, and installing new highly efficient and compact RICE units. We believe the Plant is well positioned for helping wholesale power suppliers serve growing local demand while making beneficial use of waste-heat to provide the heating and cooling needs of downtown area businesses and commercial operations on a cost savings bases. CHP is far more energy efficient than traditional power generation technologies and why treated like renewable resources by federal agencies and encouraged by most states. We also propose adding and integrating solar + storage capacity to further increase efficiencies, improve operational flexibility, and reduce costs.

From EPA’s CHP Website https://www.epa.gov/chp

What Is CHP? CHP is an energy efficient technology that generates electricity and captures the heat that would otherwise be wasted to provide useful thermal energy—such as steam or hot water—that can be used for space heating, cooling, domestic hot water and industrial processes. CHP can be located at an individual facility or building, or be a district energy or utility resource. CHP is typically located at facilities where there is a need for both electricity and thermal energy. Nearly two-thirds of the energy used by conventional electricity generation is wasted in the form of heat discharged to the atmosphere. Additional energy is wasted during the distribution of electricity to end users. By capturing and using heat that would otherwise be wasted, and by avoiding distribution losses, CHP can achieve efficiencies of over 80 percent, compared to 50 percent for typical technologies (i.e., conventional electricity generation and an on-site boiler).

CHP Benefits CHP offers a number of benefits compared to conventional electricity and thermal energy production, including: • Efficiency Benefits CHP requires less fuel to produce a given energy output and avoids transmission and distribution losses that occur when electricity travels over power lines.

HOBBS Industries, Inc Proposal for Repowering Delta’s ML&P Power Plant

• Environmental Benefits Because less fuel is burned to produce each unit of energy output and because transmission and distribution losses are avoided, CHP reduces emissions of greenhouse gases and other air pollutants. • Economic Benefits CHP can save facilities considerable money on their energy bills due to its high efficiency, and it can provide a hedge against electricity cost increases. • Reliability Benefits Unreliable electricity service represents a quantifiable business, safety, and health risk for some companies and organizations. CHP is an on-site generation resource and can be designed to support continued operations in the event of a disaster or grid disruption by continuing to provide reliable electricity.

Efficiency Benefits The average efficiency of fossil-fueled power plants in the United States is 33 percent. This means that two-thirds of the energy used to produce electricity at most power plants in the United States is wasted in the form of heat discharged to the atmosphere. By recovering this wasted heat, CHP systems typically achieve total system efficiencies of 60 to 80 percent for producing electricity and useful thermal energy. Some systems achieve efficiencies approaching 90 percent. The illustration below demonstrates the efficiency gains of a 5 megawatt (MW) natural gas-fired combustion turbine CHP system compared to conventional production of electricity and useful thermal energy (i.e., purchased grid electricity and thermal energy from an on-site boiler). Conventional Generation vs. CHP: Overall Efficiency

This is an example of a typical CHP system. To produce 75 units of electricity and useful thermal energy, the conventional system uses 147 units of energy inputs-91 for electricity production and 56 to produce useful thermal energy-resulting in an overall efficiency of 51 percent. However, the CHP system needs only 100 units of energy inputs to produce the 75 units of electricity and useful thermal energy, resulting in a total system efficiency of 75 percent.

HOBBS Industries, Inc Proposal for Repowering Delta’s ML&P Power Plant

A CHP system's efficiency depends on the technology used and the system design. The five most commonly installed CHP power sources (known as "prime movers") offer these efficiencies: • Steam turbine: 80 percent • Reciprocating engine: 75-80 percent • Combustion turbine: 65-70 percent • Microturbine: 60-70 percent • Fuel cell: 55-80 percent

Avoided Transmission and Distribution Losses By producing electricity onsite, CHP also avoids transmission and distribution (T&D) losses that occur when electricity travels over power lines. Within the five major power grids in the United States, average T&D losses vary from 4.23 percent to 5.35 percent, with a national average of 4.48 percent (Source: Emissions & Generation Resource Integrated Database [eGRID]). Losses can be even higher when the grid is strained and temperatures are high. By avoiding T&D losses associated with conventional electricity supply, CHP further reduces fuel use, helps avoid the need for new T&D infrastructure, and eases grid congestion when demand for electricity is high.

b. Overview of how we propose to work with the City

We propose partnering with the City in the redevelopment, engineering, financing, and repowering of the Plant, to include determining and implementing the most appropriate business structure, with objective of becoming a viable long-term power pooling resource for MEAN’s dispatch while passing along meaningful economic benefits to the City, such as: • Meeting or exceeding all four RFP goals. • Meeting growing power supply & redundancy needs. • Enhancing & supporting operations of the City’s microgrid. • Transitioning to a more efficient & renewable energy future. • Reducing power supply & wheeling costs as well as line losses. • Creating revenues from the sale or lease of the Plant. • Creating opportunity for ML&P to operate Plant. • Continuing to house ML&P maintenance and operations functions including staff, equipment and vehicles. • Creating new revenues from the beneficial use of waste-heat.

We propose working closely with City officials and staff to conduct an engineering analysis to determine the technical feasibility and economic viability for repowering the Plant, with supplemental solar capacity, to help MEAN and other wholesale power suppliers serve growing regional demand. We envision this analysis being conducted in conjunction with the Facilities and Point to Point Delivery Study being conducted by MEAN and Tri-State for the purpose of developing a new power source to serve the City’s growing demand as well as providing redundancy in the case of a major power outage.

As we expect these studies to confirm that repowering of the Plant to be the best and least cost option for meeting the City’s long-term power supply needs, we’re proposing to work with the City and MEAN to amend the Energy Resource Pooling Agreement (“ERPA”) for committing the Plant’s electric output and supplemental solar resources as a power pooling resource for MEAN’s dispatch in meeting the City’s needs as well as other All Requirements Purchasers.

We understand the City has determined that there is need for the development of a new power source to serve growing demand as well as to provide redundancy in the case of a major power outage.

HOBBS Industries, Inc Proposal for Repowering Delta’s ML&P Power Plant

Regular Meeting, Delta City Council, July 16, 2019 Consideration of a Funding Agreement between the Municipal Energy Agency of Nebraska (MEAN) and the City of Delta for a Facilities Study and a Point to Point Delivery Study Public Works and Utilities Director Betsy Suerth reported that staff has been analyzing their long- term power needs and through this analysis, it has been determined that there is a need for the development of a new power source to serve growing demand as well as to provide redundancy in the case of a major power outage. In 2018 a study with Tri-State Generation and Transmission (Tri-State) was positive, finding that the City system could support additional load via infrastructure expansion. The 2019 budget will allow the City to explore additional power source alternatives that could serve both the City’s redundancy needs as well as to assure adequate power for future growth. Ms. Suerth explained that the next step is to complete a Facilities Study and a Point to Point Delivery Study with Tri-State. Through the City’s Electrical Resource Pooling agreement with MEAN, they have negotiated terms with Tri-State Generation and Transmission Associates, Inc. (Tri-State) to complete the studies. MEAN has presented staff with the funding agreement to assure the City’s financial participation. Staff has obtained a verbal estimate of $35,000 for the cost of the studies. These funds are allocated in 2019 for professional services in the Transmission and Distribution sub-fund of the Municipal Light and Power Enterprise Fund.

We also understand that MEAN has identified in its 2017 IRP the need for about 45 MW of new natural gas fired generation capacity in its western region by 2024-2025 with the City of Delta being its furthest west participant.

The Municipal Energy Agency of Nebraska (MEAN) is the not-for-profit wholesale electricity supply organization of NMPP Energy. Created in 1981, MEAN provides cost-based power supply, transmission and related services to 69 participating communities in four states: Colorado, Iowa, Nebraska and Wyoming.

LOCAL CONTROL MEAN member communities benefit from local control over power supply options. Each MEAN member community has a voting representative and works cooperatively to provide the lowest possible rates and achieve the highest quality of service to their respective end-use customers. MEAN has a successful history of serving its members’ needs with reliable, economical electricity and related services.

HOBBS Industries, Inc Proposal for Repowering Delta’s ML&P Power Plant

COST-BASED RATES MEAN offers cost-based, long-term power supply. As a member-driven organization, MEAN's member communities are the owners and reap the benefits of any operational gains.

2017 INTERGRATED RESOURCE PLAN In the west, MEAN will search out the lowest cost resources for capacity and energy as determined in the analysis. MEAN will explore opportunities to contract with a natural gas combined cycle plant in the region for capacity and energy purchase or a partial ownership arrangement. Concurrently, MEAN will solicit its participants for opportunities to lease new or existing participant owned generation. If terms and costs of this option are favorable in comparison to the natural gas plant, MEAN would require a separate energy source. According to the analysis results, MEAN should explore available wind and/or solar resources, giving preference to community-based installations. In the West region, MEAN has a resource need starting in 2025. In terms of capacity, the deficit is approximately 45 MW. There is a need for capacity and energy during the remainder of the study period. An intermediate type or even an intermittent resource would fulfill the energy needs in the west.

Portfolio 1: Natural Gas Combined Cycle MEAN would contract for a partial ownership or a power purchase agreement for 45 MW of capacity and energy from a natural gas combined cycle plant. This resource is scheduled to enter MEAN’s resource portfolio to coincide with the capacity deficit. The NGCC plant would not be operated in a market, and therefore not subject to economic dispatch. However, the plant would be dispatched by the operator when local economics are favorable. This portfolio achieves the goal of diversifying MEAN’s resource portfolio.

HOBBS Industries, Inc Proposal for Repowering Delta’s ML&P Power Plant

Portfolio 5: Solar + Natural Gas Combined Cycle This portfolio also adds both renewable and fossil fuel resources to MEAN’s west region mix. In this portfolio, MEAN would enter into a power purchase agreement for utility or community owned solar generation to provide for energy needs in the west. MEAN can claim approximately half of the solar resources as accredited capacity, but in terms of nameplate capacity, MEAN would see an increase in renewables. This portfolio would also include MEAN’s partial ownership or participation in a power purchase agreement for 45 MW of capacity and energy produced by a natural gas combined cycle plant. Both resources would be added to the portfolio in 2025 when the west experiences a deficit. The proposed portfolio in the west that best achieved the primary goal of low cost was Portfolio 1, the addition of capacity and energy from a natural gas combined cycle plant. This option also provides for operational flexibility and fuel diversity, but not local benefit. The next best options in terms of cost were Portfolios 4 and 5, the combination of the natural gas combined cycle plant for capacity and energy and the addition of a wind or solar resource for additional energy needs. These options achieve the low-cost goal and increased fuel diversity, the wind and solar resources can be configured for local benefit, and the natural gas combined cycle plant allows for operational flexibility. In the west, MEAN will search out the lowest cost resources for capacity and energy as determined in the analysis. MEAN will explore opportunities to contract with a natural gas combined cycle plant in the region for capacity and energy purchase or a partial ownership arrangement. Concurrently, MEAN will solicit its participants for opportunities to lease new or existing participant owned generation. If terms and costs of this option are favorable in comparison to the natural gas plant, MEAN would require a separate energy source. According to the analysis results, MEAN should explore available wind and/or solar resources, giving preference to community-based installations.

Assumptions: 1. MEAN's estimated existing annual costs to deliver capacity & energy to City of Delta and other western district participants. 2. MEAN's annualized average demand costs based on 4-months at $14.31/kW-m & 8-months at $6.93/kW-m. 3. Current natural Gas price at White River Hub plus transportation for a total delivered cost of about $2.20/mmbtu. 4. Mean using about 50% of Plant's output to meet City's needs with other 50% being used to meet needs of other western participants and/or DMEA. 5. This analysis based on upgrading Plant with 4 x J624 units with several options to be evaluated: 2 x J624 = 8 MWnet 4 x J624 = 16 MWnet 2 x J920 = 18 MWnet 4 x J920 = 36 MWnet 6. Does not include: a. Additional line & transformer loss savings from MEAN's point of service & City's distribution system. b. Projected cost savings for new power source to serve City's growing demand & redundancy needs. c. Projected cost savings for new power resource for meeting needs of MEAN's western district.

e. Financial resources required Primarily in-kind support services from City officials, staff, and consultants in collecting data to support engineering and economic analysis and developing an acceptable business plan. At the culmination and financial closing of a successful repowering project, we propose purchasing the Plant from the City for $200,000 or alternatively leasing the Plant for $2,000 per month for 20 years with renewal option.

f. Proposed funding methods Once a mutually acceptable business plan with ERPA has been worked out and agreed to with all stakeholders, we propose soliciting both debt and equity financing proposals from MEAN, traditional investment banking entities, and Opportunity Zone sources as well as loan guarantee and initiative programs offered by federal agencies. INNIO-Jenbacher is offering to provide equipment financing to include the complete power islands with emission controls and switchgear. AES brings the means and resources for the funding solar + storage additions.

HOBBS Industries, Inc Proposal for Repowering Delta’s ML&P Power Plant

g. Project timeline We propose working closely with the City to create an aggressive schedule for advancing the project as we collect and analyze data. We would expect the initial data collection and preliminary business plan with economic models to be assembled within 12-months that will also layout a conceptual timeline. Contract discussions and agreements reached with MEAN and other stakeholders will dictate the size and when the project might be needed to help serve growing regional demand and allowing for the creation of a project timeline.

h. Other information that helps City officials understand and assess how our vision and the City’s vison align Our vision is to partner with the City to realize all that is possible from the redevelopment and repowering of the Plant in becoming a catalyst for downtown revitalization, creating meaningful long-term energy cost savings, and creating new benefits and revenues from the beneficial use of waste-heat. We also envision utilizing vacant land west of Confluence Drive, owned by the City and private land owners, for installing supplemental solar + storage capacity for interconnection with the Plant buss and/or the Palmer Substation. We envision working closely with the City and MEAN to determine the right mix of generation resources needed for serving the City’s growing electrical demand, at the least cost over next 30 years or so, that we believe should be centered around the repowering of the Plant with highly efficient natural gas fueled RICE-CHP units supplemented with solar + storage to further improve operational flexibilities and efficiencies. Natural gas fueled RICE-CHP units are a climate friendly technology capable of meeting the City’s growing power supply needs for decades to come that can be improved upon by integrating supplemental solar capacity to work hand-in-hand with the City’s existing infrastructure.

We appreciate the opportunity to present our proposal for consideration in response to the City’s RFP for the redevelopment and repurposing of its ML&P Power Plant as both a catalyst for downtown revitalization and a critical anchor of the City’s downtown core as well as for serving growing electrical demand and redundancy needs.

We believe the repowering of the Plant would fit in nicely with MEAN’s goal of better serving the City’s growing demand as well as for helping meet the needs of its western district and potentially helping DMEA meet power supply needs as it exits the Tri-State contract. We envision working closely with MEAN and the City to determine the amount of new capacity needed to meet local and regional needs.

HOBBS Industries, Inc Proposal for Repowering Delta’s ML&P Power Plant

We’re hopeful that you find our proposal of interest and invite us to finalize a project plan for the redevelopment and repowering of the Plant site, with supporting solar resources, to include a proforma, site redevelopment plan, short and long-term site redevelopment and use plans, financial plans, and final timeline for the City’s consideration.

0.10 Technical parameters

All data in the technical specification are based on engine full load (unless stated otherwise) at specified temperatures as well as the methane number and subject to technical development and modifications. For isolated operation an output reduction may apply according to the block load diagram. Before being able to provide exact output numbers, a detailed site load profile needs to be provided (motor starting curves, etc.).

All pressure indications are to be measured and read with pressure gauges (psi.g.).

(1) At nominal speed and standard reference conditions ICFN according to DIN-ISO 3046 and DIN 6271, respectively (2) According to DIN-ISO 3046 and DIN 6271, respectively, with a tolerance of +5 %. Efficiency performance is based on a new unit (immediately upon commissioning).Effects of degradation during normal operation can be mitigated through regular service and maintenance work. (3) Average value between oil change intervals according to maintenance schedule, without oil change amount (4) At p. f. = 1.0 according to VDE 0530 REM / IEC 34.1 with relative tolerances, all direct driven pumps are included (5) Total output with a tolerance of ±8 % (6) According to above parameters (1) through (5) (7) Only valid for engine and generator; module and peripheral equipment not considered (at p. f. = 0,8) ,(guiding value) (8) Exhaust temperature with a tolerance of ±8 % (9) Intercooler heat on: * standard conditions - If the turbocharger design is done for air intake temperature > 86°F w/o de- rating, the intercooler heat of the 1st stage need to be increased by 2%/K starting from 77°F. Deviations between 77 – 86°F will be covered with the standard tolerance. * Hot Country application (V1xx) - If the turbocharger design is done for air intake temperature > 104°F w/o de-rating, the intercooler heat of the 1st stage need to be increased by 2%/K starting from 95°F. Deviations between 95 – 104°F will be covered with the standard tolerance.

Radio interference level The ignition system of the gas engines complies the radio interference levels of CISPR 12 and EN 55011 class B, (30-75 MHz, 75-400 MHz, 400-1000 MHz) and (30-230 MHz, 230-1000 MHz), respectively.

Definition of output • ISO-ICFN continuous rated power: Net break power that the engine manufacturer declares an engine is capable of delivering continuously, at stated speed, between the normal maintenance intervals and overhauls as required by the manufacturer. Power determined under the operating conditions of the manufacturer’s test bench and adjusted to the standard reference conditions. • Standard reference conditions: Barometric pressure: 14.5 psi (1000 mbar) or 328 ft (100 m) above sea level Air temperature: 77°F (25°C) or 298 K Relative humidity: 30 %

• Volume values at standard conditions (fuel gas, combustion air, exhaust gas) Pressure: 1 atmosphere (1013.25 mbar) Temperature: 32°F (0°C)

Output adjustment for turbo charged engines Standard rating of the engines is for an installation at an altitude ≤ 4875 ft and combustion air temperature ≤ 86 °F (T1) Engine room outlet temperature: 122°F (T2) -> engine stop

If the actual methane number is lower than the specified, the knock control responds. First the ignition timing is changed at full rated power. Secondly the rated power is reduced. These functions are done by the engine management. Exceedance of the voltage and frequency limits for generators according to IEC 60034-1 Zone A will lead to a derate in output.

Parameters for the operation of JENBACHER gas engines The genset fulfills the limits for mechanical vibrations according to ISO 8528-9. The following "Technical Instruction of JENBACHER" forms an integral part of a contract and must be strictly observed: TA 1000-0004, TA 1100 0110, TA 1100-0111, and TA 1100-0112. Transport by rail should be avoided. See TA 1000-0046 for further details

Failure to adhere to the requirements of the above mentioned TA documents can lead to engine damage and may result in loss of warranty coverage.

Parameters for the operation of control unit and the electrical equipment Relative humidity 50% by maximum temperature of 104°F. Altitude up to 2000m above the sea level.

0.20 Mode of Operation

Grid Parallel and Island Operation - Multi Units (Auto Re-sync) While Grid connected, the unit/units load can be adjusted via its power control set point or designated option. In the event of a loss of utility, the unit/units will be able to continue operating locally without utility power. When the mains monitor relay (protective relay ANSI No. 27, 59, 81, 78- provided either by JENBACHER or the customer) is activated due to a mains failure, the engine is isolated from the mains by opening the mains circuit breaker.

The load adding and shedding capabilities of the genset documented in • TA 2108-0031 - general island operation • TA 2108-0025 for type 3 engines • TA 2108-0029 for type 4 engines • TA 2108-0026 for type 6 engines • TA 2108-0032 for type 9 engines needs to be considered by the customer in order to ensure proper operation of the equipment.

When grid is restored, the unit is provided with an automatic re-synchronization feature which will synchronize the units back to the utility through a JENBACHER Master Synchronizing Control (optional, see appropriate Spec Section) or a higher-level control system provided by the customer. The unit(s) can perform ''Black-out'' start without external auxiliary power supply to the ''dead busbar''.

1.00 Scope of supply - Module

Design: The module is built as a compact package. The engine base is bolted to the gearbox/generator base. The Engine output shafting is connected through a coupling to a gearbox. A second coupling is then provided connecting the gearbox to the generator. To provide the best possible isolation from the transmission of vibrations, the engine rests on the engine base-frame by means of anti-vibration mounts. The remaining vibrations are eliminated by mounting the complete module (engine and gearbox/generator frames) on isolating pads (e.g. Sylomer). This, in principle, allows for placing of the module to be directly on any floor capable of carrying the static load. No special foundation is required. Prevention of sound conducted through solids has to be provided locally.

Control Strategy -

Grid Parallel with KW Control – Real Power Load Control of the Generator set will be either via a 4-20mA input from the customer representing a unit KW load setpoint or a KW load setpoint entered on the Diane XT4 screen. Upon breaker closure, the unit will ramp to the setpoint at a maximum rate of (Rated Unit KW) / 180 seconds.

Grid Parallel with PF Control – Reactive Power Load Control of the Generator set will be either via a 4-20mA input from the customer representing a unit Power Factory setpoint or a Power Factor setpoint entered on the Diane XT4 screen. Upon breaker closure, the unit will maintain the setpoint.

Grid Parallel with Import/Export Control - Load Control via an Import/Export KW level entered on the Diane XT4 screen. Required will be a customer 4-20mA signal representing the Site KW (Imported and/or Exported Power) that is to be controlled. Upon breaker closure, the unit will ramp to a load that will drive the KW value represented by the 4-20mA input signal to the level entered on Customer Import/Export Setpoint entered in the Diane XT4 screen. Once at the setpoint, the unit will raise and lower load to maintain this value. If the generator load required to maintain this setpoint drops below the minimum load level of the generator set, the unit 52G circuit breaker will be opened.

Grid Parallel with Multi Unit Island Operation (Auto Re-sync) - While Grid connected, the unit/units load can be adjusted via its KW control setpoint or designated option. In the event of a loss of utility, the unit/units will be able to continue operating locally without utility power however a separate system must shed load so that

the engine is not overloaded, as per GE Jenbacher TI 2108-0031. When utility power is restored, the unit is provided with an automatic re-synchronization feature which will sync the unit back to the utility. This system will work in conjunction with a GE Jenbacher Master Synchronizing Control (see appropriate Spec Section) if so equipped.

Island Mode Operations with Blackout Starting – Island Operations with Black start capability will allow the engine to start and run without utility being present. The engine will be able to start the engine on battery power, close the generator breaker against a dead bus, and operate independently of a utility power source. The customer must ensure that there is sufficient fuel gas and pre-chamber gas at pressure in the event of a Type 6 engine so configured. The engine will start without the normal confirmation of engine block temperature or operation of a circulating AC water pump. It will be required of the operators that once the engine is connected to the generator bus, power to the engine auxiliaries be restored. Load Management is expected to be limited by the operators to the limits of the engine, as per GE Jenbacher TI 2108-0031. This system will work in conjunction with a GE Jenbacher Master Synchronizing Control (see appropriate Spec Section) if so equipped. If this is a single unit and synchronization with the utility after assuming operations is required, a Grid Parallel with Single Unit Island Operations option will be required.

Gas Flow Meter Trending - Gas Flowmeter Trending and Display (Flowmeter not included)

- Option includes a 4-20mA input that will accept the pressure and temperature corrected gas flow from a customer provided flow meter computer and will incorporate the signal into trending and displays in the Diane system.

As you know, our nearby business uses a significant amount of energy where reduced costs and the availability of CO2 would help create sustainability and expansion opportunities. We wish you well with your proposal to the City and look forward to working with you in repurposing of the ML&P Power Plant as both a catalyst for downtown revitalization, and a critical anchor for the City’s downtown core and industrial areas.

Sincerely, Zach Prock 970-275-1508
