On an unsubsidized, levelized-cost basis, wind farms in Colorado, Kansas, Oklahoma and Texas are the nation’s cheapest generation sources, with the cheapest wind in those states ranging from $46.76/MWh to around $48.85/MWh, the research found.The cheapest new gas generation, according to the University of Texas’ updated data, would be combined-cycle facilities in Idaho, Washington, Montana and Oregon at $52.50/MWh to $53.61/MWh. The lowest-cost U.S. solar farms, located in New Mexico, Arizona, Texas and Colorado, ranged from $62.79/MWh to $64.36/MWh. The only places new coal generation would be the cheapest option are three remote counties of Washington state, with levelized costs around $111/MWh. The analysis does not view new nuclear power as the most cost-effective technology anywhere in the country.While the Energy Institute’s analysis appears to bode well for the future competitiveness of wind and solar as federal tax incentives phase down, experts remain split on how the real impact may play out in the marketplace. Analysts from Bloomberg NEF, IHS Markit and Navigant Consulting, for instance, recently presented wildly diverging views on future solar capacity additions as the investment tax incentive declines for businesses and zeroes out for homeowners. IHS, the most bearish of the three on solar, also foresees a plunge in wind investment post-federal tax breaks.More ($): ‘No room for coal’: Wind, solar, gas seen as cheapest U.S. power without subsidieslast_img
