    2014 total energy use in ERCOT region up by 2.5 percent from 2013

    Peak demand 1.2 percent lower than previous year

    AUSTIN, TX, Jan. 22, 2015 — Electric use in the Electric Reliability Council of Texas (ERCOT) region increased by 2.5 percent in 2014 compared to 2013, while peak demand during the hottest part of summer decreased by a little more than 1 percent.

    This information, along with other information about power use, fuel mix and demand, are included in the 2014 Demand and Energy Report released this month by ERCOT, the grid operator and manager of the electric market for most of Texas.

    Energy use over the course of the year in the ERCOT region increased from 331,624,102 megawatt-hours (MWh) in 2013 to 340,033,353 MWh in 2014, due mainly to increases seen during the extremely cold winter months early in the year.

    At 66,454 megawatts (MW), peak demand was down by about 1.2 percent from 2013 and 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

    Natural gas, at 41.1 percent, continued to be the prevalent fuel used to generate electricity, increasing from 40.5 percent in 2013. Coal use in the overall energy mix decreased from 37.2 percent in 2013 to 36 percent in 2014.

    Wind power generation continued to increase — up to 10.6 percent in 2014, from 9.9 percent in 2013. With prolonged drought continuing to affect stored water supplies in much of the state, hydroelectric power remained at only 0.1 percent, the same as 2013.

    The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to more than 25 million Texas customers -- representing about 90 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 46,500 miles of transmission lines and 600+ generation units. It also performs financial settlement for the competitive wholesale bulk-power market and administers retail switching for 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. Its members include consumers, cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities, transmission and distribution providers and municipally owned electric utilities.
