Modifies certain provisions relating to the renewable energy

HB 2807 requires Missouri electric utilities to source increasing percentages of electricity from renewable sources like wind and solar, starting at 2% in 2011 and rising to 15% by 2025, with at least 2% specifically from solar. It creates an exemption for large commercial customers (over 80MW load) who purchase renewable energy and retire certificates, allowing them to avoid utility compliance costs. The bill establishes rules for tracking renewable energy certificates (RECs) and limits annual rate increases from compliance costs to 1%. Utilities must meet these requirements for all power sold to Missouri consumers, including purchased electricity.
