ERCOT: New gas plants can meet summer power generation demand

Sponsored by

The Electric Reliability Council of Texas (ERCOT) released its final seasonal assessment of resource adequacy (SARA) for this coming spring and a preliminary outlook for summer.

Tight conditions are expected on the power grid in early summer, but more than 2,100 MW from four new natural gas-fired power plants are expected to help improve the late summer outlook.

The new plants — Ferguson, Panda Sherman, Panda Temple I and Deer Park Energy Center — are scheduled to begin operations by August 1, with one unit expected online in early July.

ERCOT has recently broken several past records for electricity demand. Peak demand March 3 reached 54,549 MW, exceeding ERCOT’s previous March peak demand record, set in 2002, by more than 11,500 MW at a time many power generators were beginning their spring maintenance outages.

Summer peak demand is projected to exceed 68,000 MW. ERCOT’s all-time record peak of 68,305 MW happened August 3, 2011. The preliminary summer outlook says reserves will remain above 3,000 MW with normal generation outages and 2002-2013 average weather patterns. Both the spring and summer assessments count wind power at 8.7 percent of its installed capacity.

The final summer SARA will be released in early May.
