States Approve RTP Tariffs
Regulators in Minnesota and Pennsylvania have approved electric service tariffs with real-time pricing (RTP). In Minnesota, the PUC directed Otter Tail Power Co. to offer large-volume customers: 1) a customer-specific baseline load priced at a standard rate, with deviations priced hourly at the spot market, reflecting a profit margin plus marginal operating and outage costs; and 2) a simplified offer that eliminates the baseline calculation, increases fixed charges, and bills all energy use at the real-time incremental rate.
