Source: Cambridge Energy Research Associates.Notes: Combustion turbine design basis assumes 2 x 7F, dual fuel capable, nominal 340 MW. Combined-cycle gas turbine design basis assumes 2 x 2 x 1 7F, dual fuel capable, nominal 500 MW, closed-loop wet cooling. Supercritical coal unit design basis assumes nominal 600 MW unit with double reheat.Capital cost figures include owner's costs (development/permitting, land acquisition, construction G&A, financing costs, interest during construction, etc.), but exclude contractor risk premiums. Fixed O&M includes property tax and insurance as well as other fixed operating expenses (labor, maintenance materials, ongoing capital, etc.). Variable production cost includes fuel (natural gas at $6.00 per MMBtu, coal at $1.60 per MMBtu, and biomass at $2.00 per MMBtu) and variable O&M costs. Biomass design assumes a dedicated wood combustion facility. Solar PV cost estimate is based on utility scale installations.
