ERCOT Energy Use up 2.2% in 2015; Wind Surpasses Nuclear

ERCOT reported a 2.2% increase in energy usage within its region of Texas in 2015, fueled by a record-breaking summer that brought a new peak demand record approaching 70,000 MW.

The Texas grid operator released a report Jan. 15 that indicated the system consumed 347,522,945 MWh of electricity last year, nearly 7.5 million MWh more than in 2014.

According to ERCOT’s 2015 Demand and Energy Report, wind accounted for 11.7% of the grid’s energy consumption, surpassing nuclear (11.3%) as a generating source for the first time. In 2010, the nuclear and wind numbers stood at 13.1% and 7.8%, respectively.

Natural gas remains the primary fuel at 48.3% — a 17.5% increase over its 2014 share — with coal supplying 28.1%.
