The Federal Energy Regulatory Commission recently issued an order finding that a filing submitted by ISO New England and other regional entities partially complies with two FERC orders related to generator interconnections.
On May 14, 2024, ISO New England Inc., the New England Power Pool Participants Committee, and the Participating Transmission Owners Administrative Committee on behalf of the New England Participating Transmission Owners submitted in Docket No. ER24-2009-000 proposed revisions to ISO-NE’s Transmission, Markets and Services Tariff in compliance with the requirements of Order Nos. 2023 and 2023-A, which amended the Commission’s pro forma Large Generator Interconnection Procedures, pro forma Large Generator Interconnection Agreement, pro forma Small Generator Interconnection Procedures, and pro forma Small Generator Interconnection Agreement.
Also on May 14, 2024, the filing parties submitted in Docket No. ER24-2007-000 proposed revisions to ISO-NE’s Tariff.
In its order issued on April 4, FERC found that the filing Parties’ Compliance Filing partially complies with the requirements of Order Nos. 2023 and 2023-A.
FERC found that the filing parties’ proposed revisions related to a cluster study process partially comply with the requirements of Order Nos. 2023 and 2023-A.
Specifically, “we find that Filing Parties’ proposed revisions to certain definitions in ISO-NE LGIP section 1, as well as ISO-NE pro forma LGIA article 1, comply with the requirements of Order Nos. 2023 and 2023-A because Filing Parties adopt the Commission’s pro forma LGIP and the Commission’s pro forma LGIA without modification,” it said.
FERC noted that the filing parties proposed certain unexplained deviations. For example, the Filing Parties proposed an unexplained deviation in ISO-NE LGIP section 4.4 that would allow a modification to the point of interconnection to occur prior to the completion of the cluster study.
With regard to the Filing Parties’ unexplained deviations, FERC found that Filing Parties’ proposed revisions to certain sections of ISO-NE LGIP do not comply with the requirements of Order Nos. 2023 and 2023-A “because Filing Parties do not adopt the pro forma LGIP language or demonstrate that the proposed deviations satisfy the independent entity variation standard.”
FERC, among other things, directed the New England parties to adopt the pro forma LGIP section 3.4.4 language that [at any time, if a transmission provider finds that the technical data provided by an Interconnection Customer is incomplete or contains errors, the Interconnection Customer and the Transmission Provider will work expeditiously and in good faith to remedy such issues.
FERC directed the Filing Parties to submit a further compliance filing within 60 days of the date of this order that either includes revisions directed by FERC “or justifies the proposal(s) under the independent entity variation standard.”
FERC also directed changes to other elements of the filing submitted by ISO New England and the other parties.
