"Carbon free" definition modification

This bill amends Minnesota's definition of "carbon-free" electricity to include specific biomass sources. It adds that carbon-free electricity must now include biomass that generates at least 50% of a utility's annual retail sales using wood chips from: (1) tree trimming waste during non-energy timber harvesting, or (2) discarded wood products. This change directly affects electric utilities (including cooperatives, municipal agencies, and power districts) that report on carbon-free electricity sources under state law. The definition update clarifies which biomass energy qualifies as carbon-free for regulatory reporting purposes.
