NYISO Management Committee Briefs: Dec. 19, 2018

RENSSELAER, N.Y. — Interim NYISO CEO Robert Fernandez told the Management Committee on Wednesday the Board of Directors this month had “reached a unanimous decision” on the AC Public Policy Transmission Project approved by the committee last summer and would release its decision no later than Dec. 27.

The MC in June backed joint proposals by North America Transmission (NAT) and the New York Power Authority (NYPA) to build two 345-kV transmission projects that could cost $900 million to $1.1 billion and would address persistent transmission congestion at the Central East interface and Upstate New York/Southeast New York interface.

The MC selected project T027, a double-circuit 345-kV line from Edic to New Scotland, along with project T029, a standard 345-kV line from Knickerbocker to Pleasant Valley.

Winter Outlook

Vice President of Market Operations Emilie Nelson reprised the winter outlook, saying the ISO will have adequate capacity on hand to meet its forecasted peak demand of 24,269 MW for the 2018/19 winter season, well under last winter’s peak of 25,081 MW. (See NYISO Forecasts Adequate Capacity for Winter.)

Balancing Energy Tariff Revisions Okd

The MC approved Tariff changes clarifying real-time market settlements and their interaction with energy storage resources (ESRs), subject to approval by the Board of Directors in January.
ISO staffer Christopher Brown told the committee the changes do not affect calculations or require software modifications. (See “Real-time Market Settlements Clarifications” in NYISO Business Issues Committee Briefs: Dec. 12, 2018.)

Energy imbalance payments and charges address the differences among actual energy injections or withdrawals and real-time and day-ahead energy schedules. The changes apply to the injections and withdrawals of ESRs and include terms introduced and defined in the ISO’s FERC Order 841 compliance filing submitted Dec. 3 (ER19-467).
