MO HB747

Establishes renewable energy portfolio requirements for electric utilities: 2% (2011-2013), 5% (2014-2017), 10% (2018-2020), and 15% (2021+) of electricity sales to Missouri consumers, with at least 2% from solar energy or solar renewable energy credits.

Allows utilities to comply by purchasing renewable energy credits (RECs) without purchasing or delivering associated energy, and provides a 1.25x multiplier for eligible energy generated in Missouri.

Implements geographic sourcing restrictions that progressively narrow from continental U.S. (2011-2013) to regional transmission organization territory (2014-2020) to Missouri or contiguous states (after 2020).

Caps annual net compliance costs at one percent of an electric utility's annual revenue requirement, with detailed cost calculation methodology including renewable resource ownership, REC purchases, solar rebates, and integration costs.

Allows federal renewable or clean energy requirements to supersede state requirements, and requires utilities to offer solar rebates of at least $2 per installed watt for customer systems up to 25 kilowatts.
