Carbon-free definition amended.

HF 249 amends Minnesota's definition of "carbon-free" electricity to include biomass energy generated from specific wood sources. It defines carbon-free as electricity produced without carbon dioxide emissions, specifically including utility-scale electricity from wood chips derived from logging byproducts (like limbs and branches) or discarded wood products. This change directly affects electric utilities that report their carbon-free energy mix, as it expands what qualifies under current renewable energy reporting rules. The bill excludes incineration of wastewater sludge and certain waste-to-energy facilities from the carbon-free definition.
