The 2015 Demand and Energy Report, released this month by ERCOT, showed the system ended the year at 347,522,948 megawatt-hours (MWh), an increase of 7,489,595 MWh, or 2.2 percent, over the 340,033,353 MWh consumed in the region in 2014. A record-breaking summer, which brought a new all-time peak demand record approaching 70,000 megawatts (MW), contributed to an increase in electricity use in the Electric Reliability Council of Texas (ERCOT) region in 2015.
