In a year of unprecedented challenges, NEPOOL has proven its resilience again. Much like the electric grid itself, the work of NEPOOL must go on even when circumstances are trying. COVID-19 required NEPOOL to quickly adjust its business practices; in mid-March NEPOOL began conducting all of its business remotely. Despite this significant change to the format for NEPOOL meetings, progress on key initiatives has not slowed. In 2020, NEPOOL opened the dialogue on the future of New England’s power grid and markets given states’ climate goals, completed its deliberations on ISO-NE-proposed Energy Security Improvements (ESI), and vetted changes to key values used in the Forward Capacity Market – among many other things. There have been bumps in the road to be sure, but we have remained steadfast in our resolve to address the difficult issues before us as we always have– together - even though we have been physically apart since March. NEPOOL GOES VIRTUAL The move to remote meetings has been a learning experience – frustrating at times, comic at others, but through it all NEPOOL stakeholders, ISO-NE staff and representatives for the New England states persevered and pulled together. We’ve had to get used to new meeting technologies, new ways of relating to each other, and new routines. Without a doubt, we miss being able to gather in-person. We miss the depth of communication possible in hallway discussions and the important social interactions that bring us together even when the issues at hand create tension. But we have found new ways to connect and work together to build consensus - the hallmark of the NEPOOL stakeholder process. MOVING FORWARD TOGETHER Amid the disruption to our normal processes, NEPOOL continues to move forward on efforts to explore market changes that may be needed in light of the rapid evolution in our industry toward cleaner energy sources. These discussions are ongoing in two separate forums. First, the Markets Committee and Reliability Committee are working together to develop a series of studies that identify any reliability gaps that might exist in the grid of the future. Once gaps have been identified, the discussion will focus on potential market approaches that could be used to address these gaps. Second, the region is exploring potential pathways that could facilitate the transition to the grid of the future; this work is occurring at the Participants Committee. While there is still much work left to do, the discussions this year have been robust, and the healthy differences of opinion and impassioned support from different perspectives highlight the strength and rigor of our process. Ultimately, it is this vigorous discourse that will lead NEPOOL to the best solutions for our region. In short, while COVID-19 may have slowed other industries and clearly changed our personal lives in many ways, it has not changed the commitment of NEPOOL stakeholders to embrace the work that must be accomplished to meet New England’s electric needs, reliably, and at low cost through competitive wholesale markets. Like true New Englanders, NEPOOL stakeholders have persevered through these challenging times.

2 New England Power Pool A NEW LOOK FOR THE FUTURE Reinforcing NEPOOL’s progress forward and its independence as a stakeholder organization, NEPOOL unveiled a new logo and redesigned website this year. The new logo symbolizes NEPOOL’s ongoing evolution and the sparks that fly as the NEPOOL process charts a path forward for the wholesale electric system. The new website design refreshes the access to “all-things NEPOOL”, including its members, organizational documents, meeting schedule, and, most importantly, the information that is required for the collaboration, cooperation and collective decision making that is the hallmark of the NEPOOL process. The public posting of this information provides transparency into NEPOOL’s activities, facilitating public access to and understanding of the matters under consideration. A DEBT OF GRATITUDE Before closing, personally and on behalf of NEPOOL, I thank the many front line electric industry workers who continue to operate and maintain the electric grid, the region’s power generating facilities, and the transmission and distribution system in order to ensure reliable electric supply for all of New England. They are the silent heroes of the electric industry, and we all owe them a great debt of gratitude. A TRUE PRIVILEGE I have been privileged to serve as Chair during this period of immense change. While we have accomplished much during my two year tenure, the organization has even more to accomplish in 2021 and beyond. I am honored and proud to have had the opportunity to work with stakeholders and have great confidence in the continued success of NEPOOL under the incoming Chair.

The Participants Committee is the highest-level NEPOOL committee to which all matters are submitted unless they have been otherwise delegated to one of the Technical Committees – the Markets, Reliability and Transmission Committees. The Participants Committee is also supported by, and delegates some responsibilities to, two standing, self-selected subcommittees – the Budget & Finance Subcommittee and the Membership Subcommittee. The Participants Committee has eight elected officers. One officer is elected from each of the six voting Sectors to serve as a Vice-Chair of the Sector. The Committee then elects a Chair from among those six Sector representatives. The Committee also elects a Secretary and an Assistant Secretary. The Technical Committees’ Chairs and Secretaries are ISO-NE personnel appointed by ISO-NE after consultation with NEPOOL. Each Technical Committee also has a Vice-Chair who is elected from among and by the voting members of that Technical Committee. The leaders of all other subcommittees and working groups are selected by the Chair of the Participants Committee or ISO-NE following consultation as appropriate. NEPOOL meetings are attended by ISO-NE representatives and State representatives, including representatives of the New England States Committee on Electricity (NESCOE) and the New England Conference of Public Utilities Commissioners (NECPUC), who participate actively in discussions.

8 New England Power Pool NEPOOL STAKEHOLDER PROCESS

NEPOOL is the stakeholder voting organization that advises on all matters relating to New England’s competitive wholesale market rules and transmission tariff design. Its stakeholder processes are designed to maximize active and informed participation and negotiations to reach consensus among stakeholders, and where consensus is not possible, to articulate, define and limit unresolved issues. Through NEPOOL, Participants and representatives of the States, ISO-NE and the FERC provide informed and quality feedback at all levels. Informal feedback, which is a combination of education on and definition of positions, lays the foundation for consensus. Of course, consensus is not always possible, and in those circumstances, the NEPOOL process narrows and clarifies disagreements for resolution by the FERC as appropriate. NEPOOL acts through votes of the Principal Committees or by delegation to its subcommittees or elected or designated representatives.

From its original formation nearly Future Grid Study Effort. 50 years ago to ensure reliability Assessing the Future Together following the great Northeast In 2020, NEPOOL, NESCOE and ISO-NE have been working together to define a study (the Future blackout of 1965, NEPOOL has Grid Reliability Study) that would assess the evolved in response to the changing future state of the regional power system in light needs of the region. of state energy and environmental requirements. Those requirements include detailed goals for This year, in recognition of the adopting clean technology and reducing carbon changing demands on the grid emissions from the power grid, which are varied arising from evolving state among the six New England states and, some of which, have target dates out to 2050. The efforts policies and new technologies, underway are working to account not only for NEPOOL leadership, working those differing and evolving state requirements, closely with NESCOE and ISO-NE but also the differing views among NEPOOL representatives, launched New members and state and ISO-NE representatives as to the key input variables and assumptions to England’s Future Grid Initiative in inform the study. two parallel processes.

In 2020, an important chapter was Comprehensive Stakeholder added to New England’s efforts Consideration of Longer-Term Market Solutions to address the region’s evolving In July 2018, the Commission directed ISO-NE to fuel security challenges. This past file, among other things, market improvements year, NEPOOL members, State “to better address regional fuel security concerns.” For nearly 20 months afterwards, officials, and ISO-NE devoted a NEPOOL members, ISO-NE, and state officials significant amount of time and engaged in robust dialogue and candid back-and- resources to develop, understand, forth discussions on ISO-NE’s Energy Security Improvements (ESI) proposal.

Through the NEPOOL process, ESI was explored, changes were not shown to be debated, and analyzed, with ISO-NE incorporating just and reasonable, efforts to some design changes in response to stakeholder identify and explore potential feedback. To address certain remaining stakeholder concerns, NEPOOL adopted three future market changes to address modifications to ISO-NE’s ESI proposal designed demonstrated fuel security issues to strike a better balance between reliability will likely continue. benefits and costs to consumers. The three NEPOOL-approved changes were offered by NESCOE on behalf of the States. The Two Alternative ESI Proposals In ISO-NE’s April 2020 filing, two alternative ESI proposals were presented to the FERC on equal legal footing, one advocated by ISO-NE and the other advanced by NEPOOL. The ISO-favored ESI Design ISO-NE’s ESI proposal (as well as the NEPOOL alternative) included three new day-ahead ancillary services products. (1) Generation Contingency Reserve (GCR), which would procure Day-Ahead commitments for existing Real- Time Operating Reserve products (i.e., 10- and 30-minute reserve products); (2) Replacement Energy Reserve (RER), which would pay resources to be on standby to restore GCR (i.e., 90- and 240-minute reserve products) and pay resources to cover ISO-NE’s error in forecasting load; and (3) Energy Imbalance Reserve, which would compensate resources to be on standby if the energy that cleared in the Day-Ahead market was insufficient to meet ISO-NE’s load forecast.

First, under the NEPOOL both proposals. In late October, the FERC issued alternative RER would have been procured only its order, rejecting both proposals concluding that during the winter months rather than year-round neither alternative had been demonstrated to be as ISO-NE proposed. This change intended to just and reasonable. Based on the information filed, protect consumers from added RER-related costs the FERC concluded that ESI would not materially during non-winter months where there has been improve fuel security, finding that “ESI does not no demonstration of a regional fuel security need. strike an appropriate balance between addressing Second, NEPOOL’s alternative would have removed fuel security in New England while protecting a provision in ISO-NE proposal allowing it to consumers from the significant cost of those fuel purchase additional RER to cover its load forecast security benefits.” Although the FERC recognized error. By eliminating this provision, NEPOOL sought that NEPOOL’s alternative approach “would result in to protect consumers from what NEPOOL viewed as lower costs to consumers,” the FERC rejected it for unjustified costs. Third, NEPOOL—which generally the same underlying reasons it rejected the ISO- supported ISO-NE’s strike price concept—proposed NE’s proposal. to add $10 per megawatt hour to the strike price.

www.nepool.com 51 FEDERAL COURT APPEALS US Court of Appeals for the DC Circuit (unless otherwise noted)

Docket Underlying Proceedings

15-1071/ FCM Pricing Rules Complaints (EL14-7; EL15-23). NEGPA and Exelon petition for review of FERC orders accepting the FCM’s 7-year 16-1042 price lock-in (EL14-7) and capacity-carry-forward rules. Granted. Remanded to the FERC for further proceedings.

16-1325 Opinion 569/569-A. FERC’s Base ROE Methodology (EL14-12; EL15-45). Challenge to the FERC’s establishment of a new methodology for setting the ROE that electric utilities are entitled to earn on electric transmission investments. Pending.

18-1128 PennEast Project (CP15-558). Challenge to FERC orders granting certificates of public convenience and necessity to PennEast Pipeline Company for the construction and operation of the PennEast Project. Being held in abeyance.

18-3787 First Energy Solutions Bankruptcy. FERC appeal of an Ohio bankruptcy court’s ruling that blocked the FERC from taking any action (6th Cir.) on FirstEnergy Solutions Corp.’s power purchase agreement with Ohio Valley Electric Corp., which First Energy was trying to shed in bankruptcy. Affirmed in part; Reversed in part. The Sixth Circuit concluded that the bankruptcy court has jurisdiction to decide whether FES may reject the contracts, but that its injunction of the FERC in this case was overly broad (beyond its jurisdiction), and its standard for deciding rejection too limited. The Sixth Circuit went on to hold that “when a Chapter 11 debtor moves the bankruptcy court for permission to reject a filed energy contract that is otherwise governed by FERC, via the FPA, the bankruptcy court must consider the public interest and ensure that the equities balance in favor of rejecting the contract, and it must invite FERC to participate and provide an opinion in accordance with the ordinary FPA approach (e.g., under the Mobile–Sierra doctrine), within a reasonable time.”

19-1098 Allegheny Defense Project v. FERC. DC Circuit rules that the Natural Gas Act does not allow the FERC to delay appellate review of its substantive orders through its common practice of issuing tolling orders.

1 19-1142/ Order 841 (Electric Storage Participation in RTO/ISO Markets) (RM16-23). Court denies petition for review of Orders 841 and 841-A. 9-1147

19-1224 ISO-NE’s Inventoried Energy Program Proposal (ER19-1428). Review of the FERC’s June 18, 2020 IEP Remand Order. Pending.

19-71615 FERC Orders on PG&E Bankruptcy. Court dismisses as moot PG&E appeal of the FERC’s orders finding that the FERC has concurrent (9th Cir.) jurisdiction with the bankruptcy courts to review and address the disposition of wholesale power contracts, expressing no opinion on the merits of the dispute.

20-1289 2013/14 Winter Reliability Program Remand Proceeding (ER13-2266). TransCanada appeals April 1, 2020 2013/24 Winter Reliability Program Order on Remand and Compliance. Pending.

20-1329 Opinion 531-A Compliance Filing Undo (ER15-414). Given Allegheny, TOs appeal the FERC’s October 6, 2017 order rejecting the TOs’ filing that sought to reinstate their transmission rates to those in place prior to the FERC’s orders later vacated by Emera Maine. Pending.

20-1333 CASPR (ER18-619). Given Allegheny, Sierra Club, NRDC, RENEW Northeast, and CLF seek review of the FERC’s March 9, 2018 CASPR Order. Pending.

20-1343 Mystic 8/9 Cost of Service Agreement (ER18-1639). Mystic, NESCOE, MA AG, and CT Parties separately petitioned the DC Circuit Court of Appeals for review of the FERC’s orders addressing the COS Agreement among Mystic, ExGen and ISO-NE. Pending.

20-1389 CIP IROL Cost Recovery Rules (ER20-739). Cogentrix and Vistra seek review of the FERC’s orders allowing for recovery of expenditures to comply with NERC IROL-CIP requirements, but only those costs incurred on or after the effective date of the relevant individual FPA section 205 filing, including undepreciated costs of any such past capital expenditures to comply with the IROL-CIP requirements. Pending.

20-1422 ISO-NE Implementation of Order 1000 Exemptions for Immediate Need Rel. Projects (EL19-90). LS Power challenges the FERC’s June 18, 2020 order finding insufficient evidence to conclude that ISO-NE’s implementation of the exemption for immediate need reliability projects is unjust, unreasonable, or unduly discriminatory or preferential. Pending.

20-72788 Order 872 (RM19-15). Solar Energy Industries Association seeks review of Order 872 (Pricing and Eligibility Changes to PURPA (9th Cir.) Regulations).

58 New England Power Pool WHAT I MISS ABOUT IN-PERSON NEPOOL MEETINGS

Kinship and camaraderie

Cookies at the DoubleTree

Small talk before/after sessions

Catching up at the Summer Meetings

NEPOOLM&Ms

Handshakes

Face-to-face interactions

Breakfast gossip

Traffic jams to and from Westborough

Souvenir note pads and pens

The ease of turning on and off the microphone button at in-person meetings

Rekindling friendships

The hallway conversations

The splash of my coffee on the tablecloth when I bump the table leg with my knee

Asking someone to plug me in

Dressing up

Getting lost at Seaport Hotel – is the meeting in the hotel or across the street?

Dinner with fellow NEPOOLers
