MISO clears 136,912 MW in annual capacity auction

Midcontinent Independent System Operator (MISO) successfully completed its second annual planning resource auction under its enhanced resource adequacy construct this week. The auction covered the 2014-15 planning year clearing 136,912 MW of planning resources from nine local resource zones to meet MISO’s system-wide and zonal planning reserve margin requirements.

This year’s auction produced three auction-clearing prices for the 2014-15 planning year.

·      Zone 1 (Minnesota, North Dakota and Western Wisconsin) cleared at $3.29 per MW-day driven by the zone’s capacity export limitations

·      Zones 2-7 (Upper Michigan, Eastern Wisconsin, Iowa, Missouri, Indiana, Illinois, Kentucky and Lower Michigan) cleared at $16.75 per MW-day

·      Zones 8 and 9 (Arkansas, Louisiana, Mississippi and Texas) cleared at $16.44 per MW-Day as constraints related to expected intra-RTO dispatch ranges bound between the MISO South and the MISO Central/North Regions

Results of the auction indicate an excess of 12,201 MW resource credits above the system’s need to meet forecasted demand during the 2014-15 planning year, despite increases to MISO’s planning reserve margin and increases in coincident peak forecasts.

Cleared planning resources include 124,556 MW of power generation resources, 3,743 MW of behind-the-meter generation, 5,457 MW of demand response, and 3,156 MW of external resources.
