The NEPOOL Participants Committee on May 1 voted to support an expedited filing adjusting several key dates in ISO-NE’s compliance proposal for FERC Order 2023.

The commission approved ISO-NE’s compliance filing on April 4, but several dates included in the filing no longer are viable (ER24-2009, ER24-2007). (See FERC Approves ISO-NE Order 2023 Interconnection Proposal.)

To preserve the general timeline of its proposal, ISO-NE intends to push back most dates and deadlines in its original filing by about a year. This would enable the RTO to run a group study for late-stage interconnection requests that lack capacity interconnection rights. The group study would precede the main transitional cluster study, which is likely to begin in October.

A proposed revision by RENEW Northeast failed to gain enough support to pass despite support from the NEPOOL Transmission Committee. RENEW proposed to let customers with late-stage interconnection studies continue their system impact studies (SISs) until Aug. 30, arguing this could help these developers avoid restarting their studies. ISO-NE stopped working on all in-progress SISs after FERC approved its compliance proposal. (See ISO-NE Prepares Expedited Filing After Ruling on Order 2023 Compliance.)

Prior to the meeting, NEPOOL Counsel Pat Gerity told members that the Participating Transmission Owners Administrative Committee did not support filing the changes with RENEW’s revision. He wrote that, “because of the shared filing rights that are implicated, the ISO does not believe it will be in a position to file the TC-recommended Section II revisions.”

The revision fell short of the two-thirds threshold required for PC support, with 59% of the committee voting in favor at the meeting on May 1.

The PC also voted to support changes to a pair of definitions in the ISO-NE Financial Assurance Policy and approved minor changes to the operating procedures for transmission outage scheduling and metering and telemetering criteria.

Operations Report

Energy market revenues significantly increased in April compared to the same month last year, ISO-NE COO Vamsi Chadalavada told the PC.

Average day-ahead and real-time hub LMPs increased by more than 65% year-over-year. The revenue increase largely was driven by more-than-doubled natural gas costs.

ISO-NE’s day-ahead ancillary services (DAAS) market, which the RTO launched at the beginning of March, had an average daily total value of about $15 million. Following a significant price spike after the market launch in early March, DAAS prices have remained relatively stable, but they did experience a smaller spike during a period of cold weather and elevated demand in early April.

The system did not experience any emergency conditions but did experience the lowest minimum load in ISO-NE history. (See Growth of BTM Solar Drives Record-low Demand in ISO-NE.)
