Renewable Energy

Green power, in its simple form, is defined as electricity that is generated by using renewable energy sources that have minimal impact upon the earth. Two of the more commonly known renewable energy sources are wind and solar. Their popularity is based on the fact that they are naturally produced, have low operational costs, and that they produce electricity without emissions.

Solar Energy


In 2014, City Utilities added solar energy to its portfolio of locally-generated electricity, with a 4.95 megawatt solar farm. Customers can voluntarily choose to participate in this solar program and elect to have some or all of their electricity needs be provided by the energy produced at the CU Solar Farm.

Net Metering


Net metering is a process in which solar panels or other renewable energy generators are connected to a public-utility power grid and surplus power is transferred onto the grid, allowing customers to offset the cost of power drawn from the utility.

Wind Energy


Since 2009, City Utilities has been purchasing 50 megawatts of electricity from the Smoky Hills Wind Farm near Salina, Kansas.  At the end of 2015, City Utilities entered into a contract to purchase 200 megawatts of electricity from a developing wind farm in northern Oklahoma.  City Utilities is expecting to begin receiving this energy by the end of 2016.

Landfill Energy


In 2006, City Utilities began to harness the power of methane gas produced by the City of Springfield’s landfill, converting it to electricity, which provides 3.2 megawatts of electricity to CU customers.
