Plant Owner Responsible for Uncorrected ISO-NE Error, FERC Says
The Federal Energy Regulatory Commission ruled Thursday that a power plant owner must pay unnecessary capacity charges because it failed to correct ISO-NE records before a deadline set by the RTO’s Tariff (EL15-57).
GenOn Energy Management, a unit of NRG Energy, asked FERC in April to excuse it from buying replacement capacity to meet an obligation it was capable of fulfilling with its own resources.
GenOn said ISO-NE credited its Canal 2 generator in Sandwich, Mass., with capacity of only 303 MW — rather than the plant’s actual 556.5-MW output — in the March Annual Reconfiguration Auction for the 2015-2016 capacity commitment period that began June 1.

ISO-NE said, and FERC agreed, that the Tariff requires participants to file restoration plans for any capacity shortfall within 10 business days after notification of the ARA results. “The provision also makes clear that after they receive notification of their qualified capacity from ISO-NE, the onus is on resources to provide a restoration plan, as necessary, and if they do not do so, ISO-NE will procure capacity on their behalf and charge them for it,” the commission wrote.
