ERCOT said the two plants are "not required to support ERCOT transmission system reliability," and approved Vistra's requests to close its two-unit 1,200-MW Sandow Power Plant in Milam County by January 11, 2018, and its two-unit 1,200-MW Big Brown Power Plant in Freestone County by February 12, 2018.
The two Sandow units are newer, with unit 4 built in 1981 and unit 5 built in 2010, while Big Brown's two units came online in the early 1970s, according to S&P Global Market Intelligence data.
