Electric consumption increases 2.1 percent in 2013

AUSTIN, TX, Jan. 17, 2014 -- Electric use in the Electric Reliability Council of Texas (ERCOT) region increased 2.1 percent in 2013 compared to 2012, while demand during the hottest part of summer was up by about 1 percent.

This information, along with other information about power use, fuel mix and demand, are included in the 2013 Demand and Energy Report released this week by ERCOT, the grid operator and manager of the electric market for most of Texas.

Compared to 2012, ERCOT’s overall energy use increased from 324,859,701 megawatt-hours (MWh) to 331,624,102 MWh. At 67,245 megawatts (MW), peak demand was up by about 1 percent from 2012 but remained lower than the all-time record of 68,305 MW set on Aug. 3, 2011, during the hottest summer on record. One MW is enough electricity to power about 200 homes during the highest demand periods.

Generation mix changes

Although natural gas, at 40.5 percent, continued to be the prevalent fuel used to generate electricity, it dropped from 44.6 percent in 2012. Coal use in the overall energy mix increased to 37.2 percent, compared to 33.8 percent in 2012.

Wind power generation also continued to increase, up to 9.9 percent in 2013, compared to 9.2 percent in 2012. With drought continuing to affect water supplies in much of the state, hydroelectric power remained at only 0.1 percent, the same as 2012.

The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to 24 million Texas customers -- representing 85 percent of the state's electric load. As the independent system operator for the region, ERCOT schedules power on an electric grid that connects more than 41,500 miles of transmission lines and 550 generation units. ERCOT also performs financial settlement for the competitive wholesale bulk-power market and administers retail switching for 6.7 million premises in competitive choice areas. ERCOT is a membership-based 501(c)(4) nonprofit corporation, governed by a board of directors and subject to oversight by the Public Utility Commission of Texas and the Texas Legislature. ERCOT's members include consumers, cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities (transmission and distribution providers), and municipal-owned electric utilities.
