Smartgridcity™ Demonstration Project Evaluation Summary SmartGridCity™ Demonstration Project Evaluation Summary October 21, 2011 Prepared by: 2240 Blake Street, Suite100 Denver, Colorado 80205 (303) 679-8340 www.metavu.com Authors: Paul Alvarez, Kalin Fuller, David Teplinsky, and A. Kristoffer Torvik. i PREFACE Electric distribution grids across the U.S. consist of aging infrastructure in need of upgrades. Coincidentally, customers are demanding greater efficiency and services from the grid at the same time that reliability challenges – from distributed generation such as PV Solar and demanding loads such as Electric Vehicles – loom on the horizon. U.S. utilities are considering how best to modernize their grids in a manner that optimizes investments and maximizes associated benefits, thereby creating value for customers for the least cost and risk. In 2008 Xcel Energy, through its subsidiary Public Service Company of Colorado (“PSCO”), designed the most comprehensive smart grid demonstration project in the U.S. integrating generation, transmission, and distribution through grid data collection and analysis. The project was the Company’s approach to comprehensively understand how best to modernize its grid. The Company was interested in learning which capabilities were feasible, which were advisable, and which were ill-advised. The purpose of this report is to review the outcomes of the evaluation phase of the demonstration project. While designed primarily to serve as an input to PSCO grid development strategy, it is intended that the document proves useful for all readers, including policy makers, customer advocates, the electric utility industry, and technology providers. Throughout the evaluation phase MetaVu was offered full access to PSCO people, processes, and data. The evaluation phase could not have been completed without dedicated efforts from PSCO employees and business functions too numerous to mention. MetaVu would also like to recognize the supporting contributions from SmartGridCity™ technology partners Accenture, Current Group, GridPoint, OSIsoft, SEL, and Ventyx.

  • Business Models for Distributed Energy Resources: a Review and Empirical Analysis
    Business Models for Distributed Energy Resources: A Review and Empirical Analysis An MIT Energy Initiative Working Paper April 2016 Scott P. Burger1* [email protected] Max Luke1 *Corresponding author 1MIT Energy Initiative and MIT Institute for Data, Systems and Society, Massachusetts Institute of Technology, USA MIT Energy Initiative, 77 Massachusetts Ave., Cambridge, MA 02139, USA MITEI-WP-2016-02 Abstract This paper presents a novel, empirical analysis of the most common business models for the deployment of distributed energy resources. Specifically, this research focuses on demand response and energy management systems, electricity and thermal storage, and solar PV business models. We classify the revenue streams, customer segments, electricity services provided, and distributed energy resources leveraged for 144 business models. We use this empirical assessment to identify a limited set of business model archetypes in each distributed energy resource category. Within each archetype, concrete examples of individual business models are presented, along with notable exceptions or extensions of these business models. Our review leads us to five key takeaways regarding the structure of distributed energy resource business models. First, business models can be classified into a discrete number of archetypes based on common characteristics. This clustering indicates that there are factors that contribute to the success or failure of a business model that cannot be captured in reviews of business model structures (for example, company culture, or factors linked to execution). Second, as anticipated, regulatory and policy environment is a significant, if not the most significant driver of business model structure. Third, business models are not static with time – technological, policy, and regulatory developments all drive changes in a company’s business model.

  • Wind-To-Battery Project
    WIND-TO-BATTERY PROJECT As the nation’s number one wind power provider, Xcel Energy wants to harness renewable energy to the greatest extent possible. With that focus, we have launched a groundbreaking project to test cutting-edge technology for storing wind energy in batteries. Our project marks the first use of direct wind energy storage technology in the United States. Energy storage is key to expanding the use of renewable energy. Integrating variable wind and solar energy production to the needs of the power grid is an ongoing issue for the utility industry and will become even more important as the penetration of both of these renewable resources increases. The technology we’re testing has the potential to reduce the impact caused by the variability and limited predictability of wind and solar generation. Xcel Energy is testing emerging technologies and energy storage devices as part of our overall Smart Grid strategy, which aims to modernize and upgrade the grid to allow for easier integration of renewable energy sources. Project Summary Xcel Energy will test a one-megawatt wind energy battery-storage system, using sodium- sulfur (NaS) battery technology. The test will demonstrate the system’s ability to store wind Lifting a battery module into place energy and move it to the electricity grid when needed, and to validate energy storage in Photo courtesy of S&C Electric Company supporting greater wind penetration on the Xcel Energy system. NaS technology has been selected for this project because of its high storage capacity; its ability to handle a large number of charge-recharge cycles as would be incurred with an intermittent renewable energy resource; its large scale and potential for even larger scalability; its dynamic response to system changes; and its demonstrated commercial performance and availability.

  • Solar and Storage for Cities
    Photo: Angie Warren SOLAR AND STORAGE FOR CITIES Solar photovoltaic (PV) systems are an increasingly cost-effective technology that cities are deploying to make and use their own electricity as they progress towards their renewable energy, climate action, and sustainability goals. However, there are numerous circumstances in which cities may have a need for solar electricity even if the sun is not shining or in other circumstances, such as a grid outage or the need for emergency power following an extreme weather event. An increasingly common, cost-effective, and beneficial solution is to pair the PV system with a battery energy storage system (BESS): this is commonly referred to as solar-plus-storage. This resource focuses on two distinct applications for behind-the-meter (BTM) solar-plus-storage installations at city/county facilities (considered roughly analogous to commercial energy users): a. Peak load shaving or peak demand shifting: City facilities, like other industrial or commercial energy users, often must make payments based not only upon the amount of their overall energy consumption, but also the rate at which they use electricity (i.e., demand) during specific periods. These “demand charges,” depending upon the utility provider, are based on the maximum amount of electric power that a facility draws during a specific 15- or 60-minute period. Depending on how and when a facility uses electricity and the utility rate structure, demand charges can be 10-70% of a monthly electricity bill. Peak shaving refers to reducing the peak demand, often by using batteries, load shedding or potentially with solar PV.
