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
