ERCOT (Texas) Wind and Solar Generation Data


This data product offers hourly wind and solar generation data for all geographical regions in ERCOT (Texas).

Wind-powered generation contributed 84.4 thousand gigawatthours (GWh) of electricity in Texas in 2019, an 11% increase from the 75.7 thousand GWh generated in 2018. Substantial growth in wind capacity in the state was the primary reason for this increase. Texas wind capacity rose almost 17% in 2019, from 24.1 gigawatts (GW) in 2018 to 28.1 GW in 2019. Wind power accounted for 18% of the electricity generated in Texas in 2019, compared with 6% in 2010.

While utility-scale solar development has been less compared to wind development in the ERCOT region, it is beginning to gain traction. As of January 2019, there is nearly 1,500 MW of installed utility-scale solar capacity in ERCOT, out of nearly 80,000 MW of installed capacity.

In this data product, you may find System-wide and Geographic Regional actual hourly averaged wind and solar power production, STWPF, STPPF, WGRPP, PVGRPP and COP HSLs for On-Line WGRs and PVGRs for a rolling historical 48-hour period as well as the rolling future 168-hour period.

Data Collection Methodology

  • Data is updated from its source every day
  • It is unified to provide a clean, organized data for both historical and current dates of the operation - ready for analysis
  • All date and hours are quality checked for consistency and completeness steps

The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to more than 26 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 650+ generation units. It also performs financial settlements for the competitive wholesale bulk-power market and administers retail switching for 8 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.
