The debate over costs is over. Solar power won. Nuclear power lost. If your utility wants to own a new power plant, a utility-grade solar farm is a better deal than a new nuclear power plant. Perhaps that's why Warren Buffett's Berkshire Hathaway ( BRK.A) is building the world's largest solar farm and not a new nuclear power plant. Berkshire is building a massive utility-grade solar power facility, using off-the-shelf photovoltaic (PV) technology. Berkshire subsidiary MidAmerican Solar will own the facility, which is called the Antelope Valley Solar Projects. SunPower ( SPWR) designed and developed the project and will provide operations and maintenance services for the plants via a multiyear services agreement. Antelope Valley will provide renewable energy to Edison International's ( EIX) Southern California Edison under two long-term power purchase contracts. To put Berkshire's newest investment in perspective, Antelope Valley is bigger than some nuclear power plants. With a nameplate rating of 579-megawatts, Antelope Valley is larger than Omaha Public Power's Fort Calhoun Station, NextEra Energy's ( NEE) Point Beach Nuclear Plant (unit 1), Xcel Energy's ( XEL) Prairie Island Nuclear Generating units, Xcel's Monticello Nuclear Generating Plant and Dominion Resources' ( D) defunct Kewaunee Power Station. Antelope Valley is about the same size as NextEra's Point Beach (unit 2), Exelon's ( EXC) Oyster Creek Nuclear Generating Station and Entergy's ( ETR) Vermont Yankee Nuclear Power Station. Berkshire's costs are striking. Compared with a new nuclear power plant, Antelope Valley is a bargain. On capital expense, operating costs and levelized costs, solar is a better investment. Here are the numbers:
Nuclear: capex, $6 million per megawatt; production costs, $22 per megawatt-hour.
Solar: capex, $4 million per megawatt; production costs, $0 per megawatt-hour.
