Arizona Public Service completed its purchase of Southern California Edison's (SCE) ownership in Units 4 and 5 of the Four Corners Power Plant near Farmington, N.M. As part of its plan - originally announced in November 2010 - APS has permanently closed the plant's older, less efficient Units 1, 2 and 3, and will install additional emission controls on the remaining units. Acquiring SCE's 48 percent interest in the larger Units 4 and 5 will increase APS's total Four Corners capacity from 791 MW to 970 MW. APS now owns 63 percent of Units 4 and 5, which constitute the plant moving forward. The final purchase price for the Southern California Edison share is approximately $182 million.
