  1. ERCOT Pilot Project for Fast Responding Regulation Service (FRRS) PDCWG April 26, 2013

  2. Objective FRRS Pilot overview Monthly FRRS Deployments FRRS-up Response to sudden large low Frequency Events Measuring ERCOT deployed FRRS-up against rate of change of Frequency and Regulation-up deployment Monthly FRRS Performance Stakeholder Review Process Questions Next Steps ERCOT PDCWG

  3. FRRS Pilot Overview • FRRS pilot deployment obligations began on Feb. 25, 2013 at hour ending 11. • When the pilot began, there were 32 MW FRRS UP and 30 MW FRRS DOWN qualified to participate. • Additional 1 MW FRRS UP and DOWN began participating on Mar. 16, 2013. • All the qualified resources completed the qualification tests. • ERCOT has made FRRS parameter changes twice and more parameter changes are expected during the course of pilot ERCOT PDCWG

  21. Next Steps Continue to evaluate and share FRRS Pilot data with various stake-holder groups Post Preliminary (3 month) report on Pilot in early June. Perform cost benefit analysis prior to July 2013 board meeting Obtain PDCWG feedback on cost benefit analysis approach. ERCOT PDCWG

  22. Stakeholder Review Process ERCOT discussed progress of FRRS-pilot and some performance data with ETWG and PDCWG in March 2013 scheduled meeting. PDCWG meeting April 26 ETWG meeting April 30 TAC May 2 (Update on Pilot and outline options) BOD May 14 (General update, Heads-up on decision required at July BOD meeting) ERCOT PDCWG
