The Midcontinent Independent System Operator (MISO) filed a request on Sept. 30 with the Federal Energy Regulatory Commission related to the end of a System Support Resources (SSR) deal with DTE Electric for Harbor Beach Unit 1.
An SSR is designed to temporarily support a to-be-shut generating unit while MISO makes transmission upgrades that would make up for the loss of that generation. The SSR agreement in question provided for the continued availability of DTE’s Harbor Beach Power Plant No. 1 under MISO’s Open Access Transmission, Energy and Operating Reserve Markets Tariff.
On April 2, MISO submitted the SSR agreement to FERC, which the commission accepted on Aug. 26.
“MISO has determined that Harbor Beach is not required to serve in an SSR status past the final day for the SSR Agreement, which is September 30, 2013,” MISO explained in the Sept. 30 filing. “Development of the Bauer–Rapson 345kV lines, referred to in the Harbor Beach SSR Study, renders the need for continued service by Harbor Beach unnecessary.”
Harbor Beach Unit 1 is a 95-MW, coal-fired facility that went into service in 1968.
