Problems after commissioning

The Sierra Club reported in October 2010 that CPS Energy "postponed restarting its recently completed Spruce 2 coal-fired power plant, due to problems with the transformer that provides power to nearby substations via high-voltage power lines. The coal plant, which ran at full power all summer, was taken off-line in early September for more detailed inspections of the transformer and other systems. Officials expected to bring the plant back online this month, but it will remain down while the transformer is repaired or replaced."[3]
