Smart grid in China
China is the world's largest consumer of electricity, and its demand is expected to double by next decade , and triple by 2035. In 2010, 70 percent of China's electricity generation came from coal-fired power plants, but now the Chinese government is investing heavily in renewable energy technologies. As of 2013, 21 percent of China's electricity generation comes from renewable sources.〔(【引用サイトリンク】url=http://www.eia.gov/beta/international/analysis.cfm?iso=CHN )〕 This represents only 9 percent of China's overall primary energy use coming from renewable resources. China's latest goal is to increase renewable energy to 9.5 percent of overall primary energy use by 2015. To implement China's new clean energy capacity into the national power grid, and to improve the reliability of the country's existing infrastructure, requires significant upgrades and ultimately, a smart grid.
A smart grid differs from a conventional power grid in that it includes a system of information and communication technologies to bidirectionally transmit and distribute electricity more efficiently and reliably. Additionally, this technology allows consumers to manage their power usage and make choices for economically efficient products and services. China's national utility, the State Grid Corporation of China (SGCC), is responsible for the oversight of these upgrades.
== History ==
China's national utility, the State Grid Corporation of China (SGCC), announced plans to invest $250 billion in electric power infrastructure upgrades over the next five years, of which $45 billion is earmarked for smart grid technologies. Another $240 billion between 2016 and 2020 will be added to complete the smart grid project. .
