ISO-NE and NEPOOL jointly file proposed revisions to the ISO-NE/NYISO Coordination Agreement.  The revisions to the ISO-NE/NYISO Coordination Agreement (1) reflect the installation of NYISO owned tie-line meters; (2) update NERC and NPCC references;  and (3) include non-substantive changes to match ISO-NE’s currently-filed version with NYISO’s currently-filed version.

FERC denies Request for Stay of ROE refund requirement (refunds, with interest, for the period from Oct 16, 2014 to Mar 19, 2026 (the date of Opinion 594)).  In denying the Request for Stay, the FERC found that “Indicated NETOs have failed to establish that the [FERC]’s order to pay refunds … meets the standard of irreparable harm required to justify a stay.”  The FERC went on to say that, while it “need not reach whether granting a stay may substantially harm other parties or whether a stay is in the public interest, … we also find that neither of those factors would support a different outcome.”  Because the FERC denied the Request for Stay, the refund deadline remains May 20, 2027.

FERC requires ISO-NE IMM to provide Applicants with an unredacted copy of its Market Power Assessment Report pursuant to a  protective agreement (which is to contain additional conditions offered by Applicants to limit the categories of persons permitted to access the complete, non-public version of the Market Power Assessment Report (including excluding competitive duty personnel)).

State Consumer Advocates* file a complaint alleging that Eversource illegally categorized the X-178 transmission upgrade as an asset management project under section 3.08(f) of the TOA (rather than as a regional transmission project under section 2.06 of the TOA).  If properly categorized as an asset management project, State Consumer Advocates seek either modifications to the TOA or the establishment of a process for FERC review of challenges to a PTO’s classification of a project as an asset condition project under section 3.08(f).

* State Consumer Advocates are the ME OPA, CT OCC, RI Division, NH OCA and VT DPS.

ISO-NE responds to the Show Cause Order, by: (i) explaining potential changes to the Billing Policy that, if adopted, would address
the majority of the issues that the FERC raised in the Show Cause Order, (ii) explaining why it is not appropriate to modify certain, discrete, market settlement provisions that are at issue in this proceeding, and (iii) requesting that the FERC provide guidance with respect to adding a provision to the ISO’s Tariff to enable the extension of settlement deadlines by FERC  action to address settlement errors.

Extension Respondents* seek clarification or reconsideration of the Apr 14 Extension Notice (regarding a requirement for the submission of reports by NETOs/ISO-NE on the status of their efforts to process the refunds ordered by Opinion 594)

* Extension Respondents are:  MA AGO, MA DPU, CT AG, CT PURA, MOPA, NH OCA, RI Div, MMWEC, AIM, TEC, Power Options, IECG, and NHEC.
