7月8日(路透社) - 美国加州公用事业Southern California Edison公司(SCE_pe.A)周四获得监管机构批准,购买了近500兆瓦的可再生能源,更近使用可再生替代新能源目标。
加州是美国人口最多州,也是美国清洁能源的领导者。加州要求到今年年底本州所用能源有20%来自太阳能、风能等可再生能源。州政府希望这一数字到2020年能上升到33%,但事业单位需为实现这一目标而不懈努力。
加州公共事业委员会说,Southern California Edison 签署了Solar Millennium公司生产的2个242兆瓦太阳能光热发电系统20年使用合同。
太阳能热电项目位于加利福尼亚州的Blythe,预计2014年年中完成。
Solar Millennium公司拥有精湛技术,公司将采用成千上万的小镜子反射太阳光芒,加热的液体和蒸汽涡轮机制造中产生电力。
尽管1兆瓦电力已经足够800多个美国家庭使用,太阳能电源间歇性减少了其能量值。
加州公共事业委员会还批准了一项与圣地亚哥天然气和电气公司,森普拉能源(SRE.N)和Calpine公司(CPN.N)的合同,获准公司将在加州索诺玛县湖进行地热发电。根据合同,2014年后 SDG&E每年将收到大约212千兆瓦的能量。
July 8 (Reuters) - California's utility Southern California Edison (SCE_pe.A) won approval on Thursday from regulators to purchase nearly 500 megawatts of renewable power, bringing it closer to the goal to get electricity from alternative sources.
California, the most populous U.S. state and a leader in clean energy, has required its utilities to get 20 percent of its power from renewable sources, like solar and wind, by the end of this year.
The state hopes that figure will rise to 33 percent by 2020, but utilities have so far struggled to hit the targets.
Southern California Edison will use output from two of Solar Millennium LLC unit's 242-megawatt solar-thermal power facilities in California under a 20-year contract, the California Public Utilities Commission said.
The solar thermal project, which will be located in Blythe, California, is expected to be completed by mid-2014.
Solar thermal companies have technology that uses the sun's rays, reflected by thousands of small mirrors, to heat liquids to create steam in turbines and generate electricity.
While one megawatt is enough to power as much as 800 U.S. homes, the intermittent nature of solar power reduces its energy value.
The CPUC also approved a contract between San Diego Gas & Electric Co, a unit of Sempra Energy (SRE.N), and Calpine Corp (CPN.N). for generation of geothermal power in California's Sonoma and Lake Counties. SDG&E will receive about 212 gigawatt-hours of energy per year though 2014 under the contract.
