  2. Project Background ERCOT received a grant in April, 2010 from the Department of Energy to improve our Long-Term Study process. • Three primary study goals: • To provide relevant and timely information on the long-term system needs in the ERCOT Region to inform nearer-term planning and policy decisions • To expand ERCOT long-term planning capabilities by developing new tools and processes that can be used in this and future studies • To enhance stakeholder involvement and input into the ERCOT long-range planning process in a manner that is consensus-seeking, sustainable and consistent with the established ERCOT stakeholder framework.

  3. Current Status • ERCOT has developed the base tools to evaluate resource expansion and transmission needs for future scenarios • Stakeholders have defined a Business as Usual scenario – continuation of current market conditions • ERCOT has provided an initial analysis of resource expansion for BAU scenario and several sensitivities • The characteristics of other potentialfuture scenarios to be analyzedhave not been finalized • Work to-date is summarized in anInterim Project Report(http://www.ercot.com/committees/other/lts/)

  4. Progress / Timeline

  5. Long-Term Study Task Force – Knowledge Gaps • The LTSTF needs assistance in thedevelopment of base assumptions for • some technologies: • Demand-side resources • Solar Resources • Storage technologies • Geothermal • Electric Vehicles • Existing stakeholder groupshave the technical knowledgeto provide this support • Using these base assumptions, the market viability and system benefits of the technologies can be evaluated in a range of potential future scenarios • LTSTF also needs assistance in the specifications of tools to evaluate reliability needs of system operations independent of existing A/S products

  6. The Ask • We’re requesting assistance over the next 6 months to: • Help us complete our list of knowledge gaps • Provide input on specific technologies • Review proposed specifications of operational reliability analysis tool(s) • Review assumptions of market conditions for future scenarios
