Analysis
NAICS 221117 is the 2022 national industry for biomass electric power generation, part of 22111 (Electric Power Generation). Census lists 3 example activities under it in the official index.
County Business Patterns counts 116 US establishments in this code in 2023, employing 2,268 people at an average annual payroll of $120,639 per employee (91st percentile of national industries). 44% of the establishments have fewer than five employees, which is close to the national mix.
Between 2018 and 2023 the number of establishments fell 10% and employment rose 17%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
Its index entries, the activities Census uses to assign businesses to this code, include biomass electric power generation, electric power generation, biomass and power generation, biomass.
For example, operating trash disposal incinerators that also generate electricity are classified in 562213 (Solid Waste Combustors and Incinerators) instead.
Census lists 1 related activities that belong elsewhere, most often in 562213. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
Official definition

These facilities use biomass (e.g., wood, waste, alcohol fuels) to produce electric energy. The electric energy produced in these establishments is provided to electric power transmission systems or to electric power distribution systems.
