In 1883, the Minneapolis Mill Company hired William de la Barre as an engineer and agent for the waterpower works. A number of the mills had installed auxiliary steam engines to supplement the waterpower. Meanwhile De la Barre proposed to solve the waterpower problem by increasing the head and fall available. Working on the West Side canal (Minnesota Historical Society) According to Kane, “De la Barre undertook to deepen the canal and lower the tailraces under his jurisdiction, while the millers promised to lower their wheel pits, tailraces, and headraces. Before the year ended, De la Barre had deepened the canal from 14 to 20 feet and lengthened it from 600 to 950 feet. The expansion increased its flowage capacity from 30 to 40 per cent and raised the water level to produce more power by bring water to the lessees’ wheels at a greater head.

Based on the information gathered during the Environmental Assessment Worksheet (EAW) process, the comments received on the EAW, input from MPCA staff, and other information in the record, the MPCA hereby makes the following Findings of Fact, Conclusions of Law, and Order. FINDINGS OF FACT Project Description 1. The University of Minnesota Twin Cities Campus (University) is a teaching and research institution covering an area of approximately 1,154 acres and containing about 22 million square feet of buildings. 2. The University of Minnesota Board of Regents proposes to construct a new combined heat and power (CHP) project (“Project”) to provide steam for the Twin Cities campus steam distribution system and electricity. The Project includes the following equipment: a. A 22.8MW Combustion Turbine Generator (CTG) (EU 161); the CTG will use a stage, dry low NOx combustor; b. A 210 MMBTU/hr duct burner system (EU 162); c. A 270,000 lb steam/hr heat recovery steam generator (HRSG) using exhaust gases from the system; d. An aqueous ammonia-based selective catalytic reduction (SCR) system to control nitrogen oxides; e.

    PROJECT PROFILE The University of Minnesota Minneapolis/St. Paul, Minnesota 22.8 MW CHP System Site Overview In 2009, the University of Minnesota developed a Utility Master Plan to evaluate all utility systems on campus, taking into account the University’s 20-year growth projections. The Master Plan concluded that “without action, the ability to reliably provide steam energy to University facilities would be at substantial risk”. That study initiated the effort which resulted in the reinvestment in and reconstruction of the Old Main Heating Plant; a facility constructed in 1912 and retired by the University in 2000. The old facility had fallen into disrepair with all the installed equipment (6 large coal-fired boilers) abandoned in place. The newly reconstructed Main Energy Plant, opened in November, 2017 and shown to the right, houses a new 22.8 MW Combined Heat and Power (CHP) system that provides both steam and electricity to the Minneapolis campus, reducing the University’s dependence on the electric utility grid and greatly reducing University of Minnesota CHP Plant Aerial View (Source: University of Minnesota) greenhouse gas emissions. Project Overview Quick Facts After releasing the Utility Master Plan, the University evaluated several Location: Minneapolis, Minnesota solutions to address the future potential steam shortage using Market Sector: University Reliability, Sustainability, and Cost-Effectiveness as the selection CHP Generation Capacity: 22.8 MW criteria.

The Minnesota Historical Society, with funding from the Saint Anthony Falls Heritage Board, hired Hess, Roise and Company to conduct historical research on the architectural heritage and the story of historic preservation of the Minneapolis Riverfront District. The study concentrates on three categories: • The most significant examples of historic architecture in the project area • The most significant examples of historic preservation in the project area • The most significant examples of new construction in the project area Most of the examples discussed were specified in the RFP issued by the Minnesota Historical Society. Forty-five sites, several of which encompass more than one building (such as the residential area of Nicollet Island), are keyed to the maps and compiled in the list on pages 107- 117. Each section is subdivided into the following areas: East Side Milling District, Nicollet Island, West Side Milling District, and Warehouse District.
