The New York Independent System Operator (NYISO) has announced that the Federal Energy Regulatory Commission (FERC) has approved tariff revisions that will facilitate more efficient use of transmission connections between New York and Quebec. The FERC-approved plan will save New York an estimated $20 million in annual production costs.
The new enhanced interregional transaction coordination (EITC) measures will enable more frequent energy transaction scheduling between the New York and Quebec control areas. The NYISO estimates that EITC will yield approximately $20 million in annual savings to New York through reduced transmission congestion costs, better integration of renewable and intermittent resources and lower total system operating costs.Â
Once implemented, tariff changes will reduce scheduling and pricing times from hourly to once every 15 minutes at the Chateaugay interface between New York and Quebec, thus reducing market participants' exposure to potential price volatility.Â
The NYISO is working with neighboring grid operators to implement similar pricing and scheduling changes as part of a Broader Regional Markets initiative. Potomac Economics estimates annual production cost savings of $175 million for New York when EITC is fully implemented with all neighboring control areas.Â Â
Estimated annual production cost savings associated with New York rise to $193 million and $360 million throughout the region when the full array of broader regional markets measures – including coordinated transmission congestion management – become effective.Â
