Renewable Energy

CWLP is committed to planning for the long term and supplying our customers with safe, affordable, and reliable electricity. In addition, we are committed to investing in a clean energy future for our own operation as well as for our customers.

There are a number of programs for CWLP customers wanting to pursue renewable energy options you can learn about below.

Participate in Net Metering

CWLP currently allows its customers to interconnect their Renewable Energy Systems (also called Distributed Energy Resources) to its electric grid and provides net metering to those eligible and qualified at 25 kW and smaller through an application process. Since almost all renewable systems in CWLP territory consist of solar photovoltaic arrays constructed on residential or commercial properties, CWLP has developed a series of documents to help customers and contractors understand what is required to install a solar array.

This contains all the documents below plus the Residential and Commercial installation drawings for arrays of 25 kW or less, a list of CWLP-approved meter bases and Springfield Fire Department Safety setback requirements for Rooftop PV Systems.

Subscribe to mySolar

CWLP’s mySolar program allows customers to go green by purchasing locally generated solar power as an add-on to electric bill via subscription. This 250 kW installation, which began operation in December 2018, is located adjacent to the utility’s Washington Substation at 606 Old Tippecanoe Drive. MySolar provides an affordable option for solar energy for those who want to go green, but without the financial means or roof space to install their own solar. In its first year of operation, this solar installation produced 316 MWH, enough energy to power around 30 homes for one year.

Purchase Renewable Energy Credits

CWLP customers who want to neutralize the environmental impact of their monthly energy usage can do so by purchasing renewable energy credits (RECs) through the Renewable Choice program. RECs are certificates provided by "green" energy producers that guarantee they are generating electricity using only eligible renewable energy sources (such as solar, wind or biomass). One REC is equal to one megawatt-hour (MWH) of "green" electricity. A MWH is 1000 kilowatt-hours (kWh). Since the start of the program through 2019, CWLP customers have purchased 25,816 MWH of renewable energy offsets, equivalent to the annual energy use of 2,530 homes.
