SANTA FE, N.M. — Capitalizing on their $5.6 billion transmission buildout, SPP members voted last week to reduce the RTO’s planning reserve margin to 12{39e323cd6f0c7b549829c3b8f652466012503747894c8472651e628624ea833a} from the current 13.6{39e323cd6f0c7b549829c3b8f652466012503747894c8472651e628624ea833a}.
The Markets and Operations Policy Committee approved a recommendation by the Capacity Margin Task Force that members said will reduce SPP’s capacity needs by about 900 MW, saving about $1.35 billion over 40 years.
