By 2020, just two years after Fort Collins and Longmont enacted resolutions calling for 100% renewable energy by 2030, Platte River Power Authority has successfully transitioned half of its power generation to renewable sources. While that puts the public utility for Longmont, Loveland, Estes Park and Fort Collins ahead of schedule, the last 50%, and the final 10% in particular, will be far more difficult to attain, according to Pat Connors, the vice president of Platte River Power. Platte River Power Authority is expected to release its integrated resource plan, outlining exactly how it plans to reach this ambitious goal, in mid-2020. However, a new study commissioned by Community Energy and conducted by Christopher Clack of Vibrant Clean Energy, a Boulder-based software and services company supporting the transition to renewable energy, showed the massive undertaking could be more efficient by only requiring 90% or even 80% renewable energy and allowing natural gas to act as the nexus.
