For a power-only (not combined heat and power) steam system in the 5 to 25 MW range, costs generally range between $3,000 and $5,000 per kilowatt of electricity. Levelized cost of energy for this system would be $0.08 to $0.15 per kWh, but this could increase significantly with fuel costs.n the United States, direct combustion is the most common method of producing heat from biomass. Small-scale biomass electric plants have installed costs of $3,000 to $4,000 per kW, and a levelized cost of energy of $0.8 to $0.15 per kilowatt hour (kWh).
