==Southern California Edison to Divest from Four Corners==
On March 30, 2010, [[Southern California Edison]] (SCE) informed [[Arizona Public Service]] (APS) of the company's intentions to divest its 48 percent stake of Four Corners Power Plant by 2016. According to APS, Southern California Edison announced it did not plan to sell its shares on the open market. Among the issues that may have prompted SCE to divest its interests are proposed legislative initiatives to regulate carbon from power plants, Best Available Retrofit Technology requirements for the plant by fall 2010, and the possible regulation of coal fly ash as a hazardous waste.<ref>["SCE divesting of Four Corners; APS looks to buy share,"] Kathy Helms, ''Gallup Independent" March 30, 2010.</ref>
In October 2010, the California Public Utilities Commission signaled that it would no longer allow investments at [[Four Corners Steam Plant]] after 2012, in compliance with SB 1368, the Emissions Performance Standard. The law, passed in 2006, prohibited new ownership investment in power plants that fail to meet minimum performance standard for carbon emissions. Southern California Edison owns 48% of two of the generating units at Four Corners.<ref>[http://switchboard.nrdc.org/blogs/nlong/california_gets_closer_to_clos.html "California Gets Closer to Closing the Door on Coal"] Noah Long, Natural Resource Defense Council, October 18, 2010.</ref>
