IEEFA: photovoltaic + energy storage replacing coal for power companies to save hundreds of millions of dollars1

Solar photovoltaic (pv) net news: U. S. energy institute of economic and financial analysis ( IEEFA) Said the pv + storage costs have fallen sharply, may make the hybrid power generation technology American companies save money, the American companies are busy dealing with expensive traditional coal portfolio.

the think tank, said in a recent update, electric utility companies close them before the end of the service life of coal-fired units, and renewable energy alternative, will save & other; Hundreds of millions of dollars & throughout; 。

buffett's Berkshire hathaway energy company ( 伯克希尔哈撒韦公司能源) A subsidiary of PacifiCorp is one of the many electric utility company. In a recent assessment, the company found that some retired in advance of coal-fired units will bring its 1. 8 million customers & other The potential benefits & throughout; 。

, according to the IEEFA PacifiCorp coal units with & other; Cheaper and cleaner alternatives & throughout; Very high level of competition, although their electrical performance. According to the report, the company is one of the largest grid operators in the western United States, according to the different situation, close coal-fired electricity can save 2 ahead of time. 4. 8 billion dollars.

in recent years, people are paying more attention to cheaper & other; Photovoltaic (pv) + energy storage & throughout; Mainstream technology, and gradually built up with natural gas power plant cost considerable power plants. Just this month, a new analysis, the report said the two companies in certain new gas-fired plants compete with the United States.

according to the evaluation of led by Fluence, selection of the electric power company is expected to LCOEs pv + energy storage ( 39 - $48 / MWh) Will be lower than the similar median NGCC ( 60 - $116 / MWh) 。 As a reference, some of the PacifiCorp coal unit has LCOEs is higher than the $85 / MWh threshold characteristics, it is based on the company's own statistics.

in Berkshire hathaway energy subsidiary will not be confirmed until the end of summer to phase out the degree of coal, also won't confirm replacing coal technology. For now, however, some of its ideas will lead to hundreds of megawatts of solar + energy storage capacity of the surge.

as IEEFA pointed out this week, and other public power company has struck a similar move. In Nevada, for example, NV energy companies are close coal-fired power plants, at the same time, the company is taking action to increase 1 gw of solar power and battery storage capacity of 100 mw. Colorado Xcel energy, meanwhile, has submitted the solar energy, wind energy and energy storage solutions, the average price of 30 - $36 / MWh.
