Renewable project management firm Bradley acquired by Bureau Veritas More than 7,000-MW of utility-scale wind came online in Texas between 2006 and 2009, which led to transmission congestion as the wind from projects in the western and northern areas of the state were sometimes unable to reach the population centers in the eastern regions of the state. Excess wind generation was curtailed by the grid operator, the Electric Reliability Council of Texas (ERCOT) in order to keep the network operating within its physical limits, the report said.center_img Facebook Linkedin No posts to display Linkedin RenewablesWind TAGSERCOT In addition to curtailments, the imbalances caused real-time wholesale electricity prices at the West Hub in ERCOT to drop and even go negative during periods of substantial wind generation. Negative prices occur when generators are willing to pay for the opportunity to continue generating electricity.
