System Planning Begins Wind Generation Assessment Process

ERCOT’s System Planning Group under Bill Bojorquez has taken the first step in the process to assess wind generation potential throughout Texas for designation of renewable energy zones. 

Texas Senate Bill 20, signed into law August 2005, requires the Public Utility Commission to designate Competitive Renewable Energy Zones (CREZs) and develop transmission plans to deliver the power from these zones to customers.   ERCOT is working with the PUC to develop the transmission plans and other information necessary for the PUC to make this determination.

The first step was gathering input from wind generation developers and other stakeholders to identify the counties which they believed merited consideration for wind development.  System Planning is now inviting proposals from qualified consultants to assist in the analysis of the potential counties identified by the stakeholders.  ERCOT will work with the selected wind consultant to define the potential CREZs based on consistency of wind patterns, sufficiency of wind generation potential, inclusiveness of most areas from stakeholder input, and similarity of transmission interconnection.  The resulting definitions will be posted for stakeholder comment and issue resolution before the wind consultant proceeds with developing representative wind power output profiles for each potential CREZ. 

A map illustrating the aggregated input received from the stakeholders on counties to be considered for inclusion in competitive renewable energy zones has been posted under the Long Term System Study folder on the Operations and Planning page of the ERCOT Web site:

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 650+ generation units. It also performs financial settlement for the competitive wholesale bulk-power market and administers retail switching for nearly 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. Its members include consumers, cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities, transmission and distribution providers and municipally owned electric utilities.
