Wind powers Texas RE output hike

Electricity produced in Texas using renewable sources increased 12% in 2013 from a year earlier, with wind representing nearly 97% of more than 38.13 million MWh in total generation.

Electricity produced from wind rose 13% in 2013 to 36.9 million MWh from a year earlier followed by landfill gas, hydro, biomass and solar, according to a report by the Electric Reliability Council of Texas (ERCOT), which manages about 85% of the state’s electric load.

Generators reporting participate in the Texas renewable energy credit (REC) trading program. A REC is a tradable instrument that represents one MWh of renewable energy produced. That is roughly the amount of power consumed by an average home in a month.

Competitive retail electric providers must acquire and retire RECs annually based on their load-ratio share of the state’s renewable portfolio standard mandate. Any electric provider may also retire RECs on a voluntary basis to support their own claims regarding renewable power sales.

The Texas Legislature established the renewable portfolio standard as part of the restructuring of the state’s electricity market in 1999 to increase incentives for renewable energy production. The PUC implemented the REC program in 2001, and ERCOT began administering the program at the PUC’s direction. 

There was 12.82GW capacity registered in the REC program as of 31 December last year. Texas is the leading US wind state with more than double the generation capacity of runner-up California.
