Capital costs of energy technologies

From Interwest Energy Alliance Wiki

Public Service Company of Colorado (Xcel Energy) filed its "Colorado Resource Plan" with the Colorado PUC (Docket No. 07A-447E) on 15 November 2007, in which it detailed its proposed energy resource acquisition proposals through 2015.

This chart was published on page 55 of Volume 1 (PDF) of this resource plan. It details Xcel Energy's estimates for capital costs of wind, central solar, concentrating solar (with six-hour storage), biomass, geothermal, IGCC, gas-fired combustion turbines, gas-fired combined cycle, pulverized coal, dry-cooled coal (with 50% carbon capture) and nuclear. The capital costs for all wind and central solar projects are significantly lower than for any coal or nuclear technologies, with the added benefit that wind and solar projects have no fuel costs, eliminating their exposure to any future fuel cost volatility.
