Solar Market Pathways Logo

The Cook County Department of Environmental Control has received a federal cooperative award of $1.2 million to help bring community shared solar power to the region.

The Solar Market Pathways project was one of 15 awarded nationally as part of the U.S Department of Energy SunShot Initiative. Application for the cooperative agreement was made in coordination with the City of Chicago.  Additional partners include nonprofits Elevate Energy and the Environmental Law and Policy Center, and technical consultant West Monroe Partners. ComEd is also a member of the project’s Steering Committee.

A key goal of this project is to develop five to seven community solar demonstration sites for within Cook County.  The project seeks rooftop and vacant land properties to potentially serve as host sites for the pilot program.  While this grant will not fund the implementation of solar development, it will provide design, solar assessment and technical and financial feasibility analysis.  With community solar projects, there is no cost to the property owner of the host site and, instead, the property owner can benefit from lease revenue and/or reduced energy costs.

Community Solar Business Case Tool 

The Community Solar Business Case Tool provides a flexible financial model that projects the costs and benefits to the system developer and subscriber of a single community solar project. The tool incorporates administrative, transactional and customer acquisition costs for community solar projects into a publically available model for the first time.

The Community Solar Business Case Tool was developed as part of the Cook County Community Solar Project, with a grant from the U.S. Department of Energy’s Solar Market Pathways program. Development of the tool was led by West Monroe Partners and Elevate Energy with support from the Cook County project team, the National Renewables Energy Laboratory, the National Community Solar Partnership and other regional and national stakeholders.

The timing for the release of this tool is excellent for Cook County residents, with community solar enabled by new legislation in Illinois and community solar emerging as the fastest growing segment of the solar industry in the U.S.

Value Proposition

With support from the U.S. Department of Energy Solar Market pathways team and the National Community Solar partnership, expwertise was gathered from various regional and national stakeholders to develop a valid value proposition analysis for community solar.  This document contains the analysis of the value proposition for subscribers and developers and an overall summary report of the value proposition for community solar.

Bill Crediting Analysis

This document analyzes the potential bill crediting processes for subscriber management of a community solar project.  A bill crediting mechanism has been a barrier in planning the implementation of demonstration pilots, with manual or fully automated processes being too burdensome for the utlity.  During this analysis, a semi-automated process was developed that proved to be significantly less costly.

Economic & Policy Barriers Resolutions and Work Plans

This is an analysis of the barriers, potential resolutions and recommended next steps for community solar to develop in Cook County.

Best Practices Analysis

Best Practices Front Page

The Cook County Community Solar Best Practices Analysis identifies model programs and best practices in Community Solar.  Through research of national community solar material from leading authorities and examination of case studies from successful community solar programs this analysis will provide a framework and clear pathway for establishing policy positions to incentivize and accelerate community solar in Cook County.
