7. Community Solar in Illinois- General
Projects have been planned by solar developers – not yet built
Not all will be built
Majority of cost to build Community Solar resources will be supported by selling Solar Renewable Energy Credits (“SRECs”) to the utilities
Most projects are proposed for siting outside of the metro region

All municipalities have at least some accounts that will benefit – even Franchise accounts.
Nominal cost to participating municipalities to defray start up costs
Progress on Sustainability
Municipalities can directly support new solar development in the region
Can serve as a response to the growing “100% Renewable” campaigns
Manageable Level of Effort
Municipality provides copies of most recent ComEd bills for each account
CS2 will identify which accounts can capture savings
Municipality can decide whether to enroll accounts into the CS2 program
