Springfield is the state capital of Illinois and home to Abraham Lincoln's pre-presidential home, now a national historic site. The city is served for electricity by CWLP — City Water, Light & Power — a municipal electric utility operated by the City of Springfield itself. This makes Springfield similar to Burlington VT (Burlington Electric) in having a city-owned electric utility rather than an investor-owned company. CWLP handles electric, water, and sanitary sewer for the city. Natural gas is served separately by Nicor Gas. Illinois contractor licensing applies.
Net metering is available in Springfield through City Water, Light & Power (CWLP). Confirm current net metering terms and credit rates with City Water, Light & Power (CWLP) before finalising system design — net metering policies across the country have been changing. The ground snow load in the Springfield area requires racking engineered for local snow conditions — not a generic national specification. Cold, clear days in Springfield's winters improve solar panel efficiency, partially compensating for shorter winter days. Springfield receives adequate annual solar resource for cost-effective grid-tied solar.
