Loveland, Colorado [The Daily Reporter-Herald] City officials may make renewable energy a more affordable option for Loveland utility customers. A proposed rate change supported by the Loveland Utilities Commission on Wednesday would lower the current wind program premium of $2.50 for every 100 kilowatt-hours to $1.50. The city largely buys wind electricity from the Medicine Bow Wind Project, a wind farm with 10 turbines that is owned and operated by the city’s power wholesaler, Platte River Power Authority. … With more emphasis on renewable-energy credits, the Power Authority cut its wind rate to Loveland, Fort Collins, Estes Park and Longmont in half. The changes are in part a response to Amendment 37. Approved by voters last fall, the state constitutional amendment requires utilities with more than 40,000 customers to obtain 10 percent of their energy from renewable resources, namely wind, by 2015. … The rate change goes before the City Council in June. If passed, it would take effect July 1.
