High Quality Content by WIKIPEDIA articles! Sunrise Powerlink is a high-voltage power transmission line by San Diego Gas & Electric (SDG&E) in San Diego County, California and Imperial County, California. The project was approved by the United States Forest Service (USFS) in July 2010, the U.S. Bureau of Land Management (BLM) in January 2009 and the California Public Utilities Commission (CPUC) in December 2008. SDG&E states that the 117-mile (188 km) long 230/500 kilovolt power line will bring 1000 megawatts of renewable energy from the Imperial Valley to San Diego County. The cost of the project is estimated to be $1.9 billion for construction. SDG&E, which will receive a guaranteed profit of over $1.4 billion from the construction of the line, claims that the power line is necessary to support future growth of the San Diego region and its economic benefits to the region will measure on the order of $100 million per year. However, the project has been called one of the most controversial projects ever proposed.
