Energy / Regulated Electric & Gas Utility · Deep dive

Eversource Energy

New England's largest energy delivery company (NYSE:ES) — ~$28-30B rate base electric + gas monopoly serving ~4.4M customers in CT, MA and NH — is a franchise that has, in three years, torched roughly $1.6B pre-tax on an aborted offshore-wind push, been credit-downgraded six times by Moody's since October 2023, cut A- to BBB+ by S&P in December 2024 for a 'recent pattern of adverse regulatory developments' in Connecticut, sold its Aquarion water utility at a ~$300M loss to raise cash, and is now trying to fund a $26.5B 2026-2030 capex program under an openly adversarial Connecticut regulator.

at risk

A $28B rate-base delivery monopoly is only as safe as its regulator, and Connecticut's regulator has spent three years — six Moody's downgrades, an S&P notch cut, $500M+ in disallowed storm costs, and a public presumption that Eversource is bidding above its actual capital needs — telling Eversource that the political capital to earn a full allowed ROE on the next $26.5B of capex is gone.

Snapshot

Eversource Energy is New England’s largest energy delivery company — the regulated electric and gas monopoly across most of Connecticut, eastern Massachusetts, and New Hampshire — serving roughly 4.4 million customers through six operating subsidiaries: Connecticut Light and Power (CL&P), NSTAR Electric d/b/a Eversource, Public Service of New Hampshire (PSNH), Yankee Gas, NSTAR Gas d/b/a Eversource Gas, and Eversource Gas of Massachusetts (the former Columbia Gas of MA book, acquired for $1.1B in October 2020). It reported $11.9B of FY2024 revenue on $4.57 non-GAAP diluted EPS and is guiding $4.72-$4.80 for FY25 (ES 8-K, July 2025). The company has ~$30.6B of rate base as of 2024 and a $26.5B 2026-2030 capex plan targeting $49.3B of rate base by 2030 — an 8.3% projected rate-base CAGR (Investing.com summary of Q4 2025 investor slides, February 2026). Under the surface, the last three years are the story: an aggressive 2019-2022 offshore wind push that cost roughly $520M pre-tax to unwind through the 2024 Global Infrastructure Partners sale of South Fork and Revolution Wind and the Ørsted-facing Sunrise Wind exit; six Moody’s downgrades of Eversource and its subsidiaries since October 2023; S&P cutting Eversource from A- to BBB+ in December 2024 citing a “pattern of adverse regulatory developments” in Connecticut; the January 2025 announcement — closed 30 June 2026 — of the $2.4B sale of the Aquarion water utility to a Connecticut quasi-public authority at a ~$300M book loss; and a July 2026 PURA order disallowing more than $500M of a $1.376B storm-cost recovery request. The stock traded near $88 in early 2022, bottomed near $52 in October 2023, and sits in the low $70s in September 2026 — the market’s read that the earnings algorithm still works, but with far more regulatory drag than the utility-index median.

Founding story

Eversource is a merger identity, not a founding. The oldest constituent piece is Connecticut Light and Power, formed in 1927. Northeast Utilities was organised in 1966 as a Connecticut-based holding company for CL&P, Western Massachusetts Electric and Hartford Electric Light. NSTAR Electric & Gas was the eastern Massachusetts urban utility descended from Boston Edison (electric) and Commonwealth Gas / Boston Gas (gas). On 18 October 2010 the two boards announced an all-stock combination valued at roughly $17.5B; the deal closed in April 2012, at the time creating New England’s largest energy-delivery company by both customer count and rate base. For three years the combined entity operated under the Northeast Utilities name; on 2 February 2015 it rebranded to Eversource Energy and changed its NYSE ticker from NU to ES effective 19 February 2015 (Yahoo Finance / SCW-Mag).

The “founders” for a regulated utility of this vintage are the current operators. Joe Nolan is a lifer — 35-plus years inside NSTAR and then Eversource across customer service, government affairs and corporate strategy — promoted from EVP Strategy to President & CEO on 5 May 2021, replacing James Judge (BusinessWire, 7 April 2021). Nolan was elevated on the specific promise of repairing the CT regulatory relationship damaged in the 2020 Tropical Storm Isaias restoration failure; five years in, that relationship is measurably worse. CFO John Moreira, a 22-year Eversource veteran, was promoted from Treasurer in May 2022 (Hartford Business Journal). The senior team is defined by two features: it is entirely internal, and it inherited an already-committed offshore wind position that it then had to unwind.

How it works

At the operating level Eversource is a rate-of-return utility. Each subsidiary — CL&P, NSTAR Electric, PSNH, Yankee Gas, NSTAR Gas, Eversource Gas of MA — files periodic base-rate cases with its state regulator (CT PURA, MA DPU, NH PUC); FERC governs the transmission segment on a formula-rate basis. The regulator approves a rate base (the depreciated net investment in plant plus working capital minus deferred taxes), an allowed weighted-average cost of capital and an allowed return on equity (ROE); the resulting revenue requirement is recovered from customers through delivery-charge tariffs. The mechanism is functionally: build wires, poles, pipes, meters and substations; get them into rate base; earn the allowed ROE on the equity portion. Every dollar of capex compounds into future earnings at the allowed ROE.

Transmission is the crown jewel of the model. Eversource’s transmission rate base was approximately $9.8B at year-end 2023 — ~$4.1B at CL&P, ~$3.9B at NSTAR Electric, ~$1.8B at PSNH (ES 10-K, FY2023). Transmission ROEs are set by FERC (currently ~10.57% base plus incentive adders in some ISO-NE cases), materially above state distribution ROEs (CT PURA has driven CL&P’s authorized ROE down to ~9.3% in 2024 rate orders); the FERC formula-rate mechanism also trues up annually, minimising regulatory lag. Whenever an Eversource investor slide references outsized transmission investment, the message is: earnings we can lock in without a hostile state regulator.

Distribution — the wires from substation to home — is the largest capex bucket at 42% of the 2026-2030 plan versus 27% transmission (Investing.com summary of Q4 2025 slides, February 2026). MA electric distribution operates under a decoupling / performance-based ratemaking framework with a mostly cooperative DPU; CT electric distribution operates under a much more adversarial PURA that has repeatedly denied requested ROEs, cut approved capex, and issued a landmark 2024 order framing Eversource’s rate requests as excessive. NH distribution runs a hybrid mechanism with a still-functional NH PUC relationship. Gas distribution — Yankee Gas, NSTAR Gas, Eversource Gas of MA — is subject to increasing political pressure in MA around gas retirement / decarbonisation, but for now still earns rate-base returns on integrity capex, main-replacement mandates and the ongoing Columbia Gas of Massachusetts integration.

Storm cost recovery is a specific vulnerability of the model. Actual storm-restoration spend accrues to a regulatory asset; the utility then files a prudence-review docket asking for full recovery plus a carrying charge. Under a cooperative regulator, near-full recovery is routine. Under CT PURA post-2019, it is not — the July 2026 order approving only $667.8M of a $1.376B request and rejecting a $75M storm-reserve replenishment (CT Mirror, 29 July 2026; CT News Junkie, 3 August 2026) demonstrates the mechanism turning against the utility.

Product and business overview

Electric distribution — CL&P (~1.3M CT customers), NSTAR Electric (~1.5M eastern MA customers) and PSNH (~530K NH customers). Wires, poles, transformers and substations; the physical delivery layer. Rate base concentrated in aging overhead distribution plus increasing undergrounding for storm resilience.

Electric transmission — Bulk 115-kV to 345-kV transmission across CL&P, NSTAR Electric and PSNH territories. FERC-regulated formula rate; ~$9.8B rate base at year-end 2023 with steady incremental build for New England Clean Energy Connect-adjacent needs, offshore wind interconnection, and load-growth headroom. Highest-ROE segment.

Gas distribution — Yankee Gas (~250K CT customers), NSTAR Gas (~300K MA customers) and Eversource Gas of Massachusetts (~330K MA customers post the October 2020 $1.1B NiSource / Columbia Gas transaction). The Columbia Gas book was acquired at 1.4x rate base after the 2018 Merrimack Valley over-pressurisation explosions killed one, injured 25 and forced NiSource out of Massachusetts (BusinessWire, February 2020). The bar for Eversource on that book — safety-first pipe replacement — is a rate-base story that MA DPU has funded.

Aquarion Water (divested) — Regulated water utility across 60 CT / MA / NH communities, ~230,000 connections. Acquired December 2017 from Macquarie Infrastructure at $1.675B EV; sold 30 June 2026 to the Aquarion Water Authority for $2.4B EV at a ~$300M book loss recognised in Q4 2024, reflecting the write-down between purchase price plus subsequent capex and the CT-mandated sale price (Boston Globe, 28 January 2025; ES 10-K, February 2025; ES IR, 30 June 2026). Net cash proceeds of ~$1.7B used to displace parent-company debt.

Offshore wind (divested) — Four projects developed 50-50 with Ørsted from 2016: South Fork Wind (132 MW, in service 2024), Revolution Wind (704 MW, under construction), Sunrise Wind (924 MW) and a smaller Bay State Wind. Eversource sold its Sunrise stake back to Ørsted, its South Fork and Revolution stakes to GIP for $745M (announced $1.12B, cut $375M for delays and lower capex through close), and recorded a ~$520M aggregate net pre-tax loss on the divestiture with an additional $360M residual liability expected to settle in 2026 (BusinessWire, 30 September 2024; ES IR, 14 October 2025 update).

Business model and pricing

Eversource earns a state-authorised ROE on equity-financed rate base plus embedded cost of debt on debt-financed rate base; total revenue requirement is set as: (rate base × allowed WACC) + O&M + depreciation + taxes. Fully passed through to customers as delivery-charge tariffs. Supply (the actual electrons or molecules) is a passthrough — customers pay generation suppliers directly, Eversource earns nothing on it. All economic gravity is in the delivery / distribution / transmission wedges.

Illustrative recent numbers: ES targets rate base of $30.6B (2024) growing to $49.3B (2030) at 8.3% CAGR; Q1 2025 Eversource management guided approximately 7-9% rate base CAGR through 2029 (ES 8-K, Q4 2024 investor slides, February 2025). Every 100 bps of allowed ROE granted or denied by a state regulator on $30B of rate base is worth roughly $300M pre-tax annually. The CT PURA framework Marissa Gillett drove is estimated by sell-side analysts to have shaved 30-50 bps off achievable ROE relative to a benign regulator — worth ~$90-$150M annualised for CL&P alone. That is the mathematics of why credit-rating agencies flagged CT specifically.

Consumer pricing: NuWatt tracked Eversource CT residential delivery rates at $0.36/kWh in 2026, up 18.8% year-over-year (NuWatt, 2026). Total all-in residential bills routinely exceed $0.30-$0.35/kWh in eastern MA and CT, well above the US average near $0.17/kWh — a political liability that AG William Tong (CT) and MA Attorney General Andrea Campbell both weaponise in every rate case.

Traction over time

Sources: Eversource 10-K filings (2019-2024), FY24 8-K (12 February 2025), FY25 8-K guidance (July 2025), Q4 2025 investor slides (February 2026 via Investing.com), Panabee summary of 2025 annual earnings, Zacks / MacroTrends dividend history.

The pattern: revenue plateaued at $11.9B in 2023-2024 (a decline in absolute dollars as supply-cost passthroughs normalised), EPS keeps compounding at guided 5-7% off a growing rate base, dividend growth continues its 27-year streak — but the equity multiple compressed from ~22x forward earnings in early 2022 to ~14-15x forward earnings by late 2023 as Moody’s / S&P downgraded and CT regulatory posture hardened. The stock has recovered modestly through 2025-2026 but has not re-rated to the pre-2023 multiple.

Market analysis

The addressable market is the New England electric and gas delivery service territory. Eversource holds ~4.4M customers versus ~7-8M households / meters across CT / eastern MA / NH. In electric delivery it is effectively the incumbent monopoly across CL&P’s, NSTAR Electric’s and PSNH’s franchise areas; competitive supply choice exists at the commodity layer but the wires are Eversource’s.

Structural drivers are positive on load and mixed on political posture. Load growth in ISO-NE — which was flat-to-declining for a decade as efficiency and rooftop solar offset population growth — is now robustly rising through 2025-2026 driven by (1) transportation electrification (MA and CT EV mandates), (2) building-heating electrification (heat pumps in the MA and CT state plans), (3) reshored manufacturing, and (4) data center interest, though Nolan told investors Eversource is “resisting data centers” that don’t bring bring-your-own-power arrangements. The 2025-2030 MA DPU electric-sector modernisation plan (ESMP) and CT PURA equivalent frameworks both mandate additional grid capex — good for rate base if the regulator allows recovery, bad if the political ceiling on retail rates blocks recovery.

On the political axis the environment has worsened materially since 2021. CT AG William Tong has run repeated public campaigns against rate increases including a July 2026 attack on Eversource’s $727M annual rate hike filing that would raise average residential bills 18% (CT Mirror, 20 May 2026; CT Public, 28 July 2026). MA AG Andrea Campbell and the CT Office of Consumer Counsel have both intervened aggressively. A July 2026 lawsuit by Eversource and UI accuses the state of exceeding its authority under a 2025 law (CT Mirror, 2 July 2026) — a legal war between regulator and utility that is unusual in scale.

Total addressable capex — the plan Eversource is running against — is $26.5B over 2026-2030 (Investing.com summary of Q4 2025 slides, February 2026). Delivering 60%+ of that in Massachusetts (where the DPU relationship is functional) and layering FERC transmission on top is the strategic hedge. The Connecticut segment, ~40% of Eversource’s rate base, is the risk-adjusted low ground.

Competitive intel

Regulated utilities do not compete for customers directly. The competitive set is regulatory-adjacent.

Avangrid (Iberdrola sub — CT: United Illuminating, ME: Central Maine Power) is Eversource’s direct CT regulatory peer. Every PURA precedent applies to both. Iberdrola took Avangrid private in December 2024 at $2.55B / $35.75/share — a bet by the parent that CT regulatory risk is best absorbed off public markets. That transaction implicitly re-rated the CT franchise value. National Grid (LSE-listed) is the largest gas distributor in the northeastern US and Eversource’s direct MA gas competitor; larger scale, same New England regulatory headwinds. Unitil (NYSE: UTL) is the small-cap NH/MA/ME peer; useful for MA DPU comparative posture. PPL Corporation now owns Rhode Island Energy after the 2022 acquisition from National Grid — same ISO-NE market context.

Non-regulated competitive threats are more strategic than share-eroding. Global Infrastructure Partners (now BlackRock-owned) is the counterparty that structurally profited from Eversource’s offshore wind exit at a $375M discount to expected proceeds — a case study in the danger of the utility model’s rate-base incentives when regulators are hostile. Ørsted now runs the OSW build with GIP rather than with a regulated-utility partner; the merchant-plus-PPA structure competes with utility-owned generation. Municipal utilities (Reading Municipal Light, Norwood, Braintree Electric, Concord Municipal Light, CMEEC) charge 20-40% below Eversource residential rates in adjacent towns — not a share threat but a permanent political weapon. Community Choice Aggregation programs erode supply revenue but not delivery margin. The real long-term structural threats are (i) hyperscaler C&I bypass PPAs (Meta, Amazon, Microsoft, Google increasingly co-locate at generation nodes and sign direct-with-generator PPAs), and (ii) DER + VPP stacks — Tesla, Sunrun, AutoGrid, Franklin Energy, community-solar developers like Nexamp and BlueWave — that eat behind-the-meter kWh sales while the utility earns nothing on the distributed asset.

What people say

The case for. Eversource is a scaled, first-tier regulated utility with $30B of rate base, a 27-year dividend growth streak, guided 5-7% long-term EPS growth off a $26.5B five-year capex plan, and 60%+ of new distribution capex in Massachusetts where the DPU has been broadly supportive. Its transmission segment — ~$9.8B rate base at year-end 2023 with FERC formula-rate mechanics — provides high-quality earnings insulated from state-regulator noise. The Aquarion sale at $2.4B EV extracted capital from a low-growth water business at a modest book loss and returns Eversource to pure-play electric and gas delivery, focused on the parts of the balance sheet that compound at the allowed ROE. Nolan’s team executed the offshore-wind exit cleanly on the terms the market had already priced. Guggenheim, Wells Fargo and BofA have kept buy-rated coverage through the downgrade cycle on the view that (i) transmission ROEs are stable, (ii) MA capex is fundable, and (iii) the S&P BBB+ rating is still investment grade and allows continued market access. The stock’s ~$71 September 2026 level implies partial recovery of the multiple after the 2023-24 credit action.

The complaints. The specific criticisms are structural, not one-off. First, the offshore wind write-down: a JV commitment made with Ørsted in 2019 at the top of the OSW enthusiasm cycle, sold five years later at a $375M shortfall to expected proceeds plus a $360M residual liability (BusinessWire, September 2024). Second, the CT PURA relationship: six Moody’s downgrades since October 2023 (Hartford Business Journal, 2024), an S&P downgrade to BBB+ citing “adverse regulatory developments” (CT News Junkie, 11 December 2024), and a July 2026 PURA order disallowing more than $500M of a $1.376B storm-cost request (CT Mirror, 29 July 2026). Third, executive compensation optics: Joe Nolan’s total 2023 pay reached $19M, up 46% year-over-year, while his in-process performance shares tracked substantially below target — a package that Simply Wall St flagged as needing shareholder review (Sahm Capital, April 2024) and the Boston Globe rehashed in May 2026 in a story pointedly titled about executive pay “while your energy costs soared” (Boston Globe, 18 May 2026). Fourth, customer complaints: consumer-facing coverage by CT Mirror, CT Public and Hearst Connecticut newspapers has run for years on the specific claim that CT residential bills — reported at $0.36/kWh delivery in 2026, up 18.8% Y/Y (NuWatt) — are unaffordable and that the political process has run out of tolerance for further increases. Fifth, storm restoration: the 2020 Tropical Storm Isaias failure, in which ~1M customers lost power and the pre-storm forecast was off by 40%+ (CTPost / NBC News, August 2020), is still the reference point for every subsequent PURA storm-cost prudence review. Sixth, credit spreads: the six Moody’s downgrades and S&P cut widen the utility’s cost of capital at precisely the moment it needs to fund a $26.5B five-year plan.

Outlook: well positioned or at risk?

At-risk. The Eversource business model is rate-of-return on regulated rate base — every dollar of allowed rate-base recovery compounds into earnings, and every dollar of disallowed cost is a straight loss to the equity. That model works only when the regulator plays inside its historical band. Since October 2023 the Connecticut regulator has, on documented evidence, moved outside that band: six Moody’s downgrades of Eversource and its subsidiaries (Hartford Business Journal, 2024), an S&P downgrade from A- to BBB+ citing “recent pattern of adverse regulatory developments” (CT News Junkie, 11 December 2024), and a July 2026 order approving only $667.8M of a $1.376B storm-cost request while rejecting a $75M storm-reserve replenishment (CT Mirror, 29 July 2026). Multiple structural forces push against a reversion. First, retail electric rates in Eversource’s service area have reached ~$0.36/kWh in CT (NuWatt, 2026) — the political ceiling on further rate increases is empirically at hand, and both the state AG (Tong) and Office of Consumer Counsel treat every rate case as adversarial. Second, the offshore-wind episode showed the strategic-execution gap: the JV was underwritten in a benign 2019 rate environment and unwound at a $520M aggregate loss plus $360M residual liability in a hostile 2024 environment (BusinessWire, 30 September 2024). Third, six Moody’s downgrades and the S&P cut widen Eversource’s cost of capital in the exact five-year window it must issue debt and hybrid equity to fund the $26.5B 2026-2030 plan (Investing.com summary of Q4 2025 slides, February 2026). Fourth, the Aquarion sale — a growth-diluting divestiture of the water franchise at a ~$300M Q4 2024 book loss — is a signal that the company is now capital-constrained, not capital-choosing. Fifth, the underlying tech-shift risk is real if latent: distributed energy resources, community choice aggregation, hyperscaler C&I bypass, and municipal-utility comparators all sit on the wrong side of Eversource’s rate-base incentives.

What would flip the call: (i) A new CT PURA regime post-Gillett that agrees to full recovery of the pending $727M rate case and multi-year rate plan restoration — plausible under a Lamont-appointed replacement but not guaranteed. (ii) FERC transmission incentive-rate expansions materially lifting the ~$10B transmission rate base earnings capacity. (iii) MA DPU maintaining its cooperative posture through the ESMP capex ramp — probable but not certain if MA political headlines catch the CT contagion. (iv) A large hyperscaler bring-your-own-power data-center deal that generates rate-base capex without residential-rate pressure. Absent one of these, the base case is a five-year period of allowed-ROE compression, credit-spread pressure and permanently reduced valuation multiple relative to peers.

How to attack it

Head-to-head attack on a regulated distribution monopoly is impossible — the state grants the franchise. The attack surface is around the monopoly: on the customer side (grid-edge, VPP, DER, storage-as-a-service, resiliency-as-a-service, community solar), on the C&I side (data-center BYOP bypass, industrial resiliency microgrids) and on the regulatory-services side (interconnection SaaS, rate-case software, storm-cost accounting).

Wedge 1: C&I resiliency and behind-the-meter storage-plus-solar. New England industrial and commercial customers paying $0.30-$0.35/kWh have IRR headroom for on-site solar plus 4-hour battery plus microgrid controllers that Eversource has zero rate-base incentive to enable. Tesla, Sunrun, Generac, Enphase and Franklin Energy already occupy pieces of this stack; a New-England-focused C&I resiliency operator building on hyperscaler-grade project finance could grab material load in five years. Reference: Bloom Energy’s fuel-cell C&I book, EnPowered’s demand-response network.

Wedge 2: virtual power plant + DER aggregation for ISO-NE. ISO-NE’s Forward Capacity Market and ancillary services markets accept aggregated DER bids. AutoGrid (Schneider), Tesla Powerwall VPPs, Sunrun’s Puerto Rico VPP model and Voltus / CPower are the reference. Eversource’s rate-base model treats a VPP as a revenue-loss vector, not a customer benefit; a specialist aggregator that fronts customer-owned batteries into ISO-NE markets while sharing revenue with the customer is the classic asymmetric attack.

Wedge 3: interconnection-and-permitting SaaS for the top-30 US utilities. Eversource’s Q3 2025 MA-DPU disclosures describe interconnection queue congestion at named substations (Tremont, West Pond) as a persistent operational headache. Vertical SaaS ingesting parcel geometry, load-flow model exports, jurisdictional code and rebate program rules to accelerate DER interconnection has a small but concentrated buyer set — the top-30 investor-owned utilities plus muni utilities plus state energy offices. Reference: Verogy, PowerFlex, Extensible Energy on the DER side; Enact, Aurora on the origination side.

Wedge 4: data-center BYOP siting and behind-the-meter generation partnerships. Nolan’s public “resisting data centers” comment signals that Eversource cannot underwrite the grid buildout for large hyperscaler load without unacceptable residential-rate impact. A specialist siting-plus-generation platform aggregating industrial land, gas-turbine or fuel-cell BYOP capacity, and long-term hyperscaler PPAs bypasses Eversource entirely while landing on the same physical geography.

The exploitable weaknesses. (i) CT PURA hostility caps rate-base capex recovery — six Moody’s / one S&P downgrade documented (Hartford Business Journal; CT News Junkie, December 2024). (ii) Offshore-wind write-down ($520M net; $360M residual liability) is a governance data point every credit report cites. (iii) Aquarion divestiture at a ~$300M book loss signals capital constraint. (iv) $0.36/kWh CT delivery rates (NuWatt, 2026) mean the political ceiling on further increases is at hand. (v) Executive compensation optics — Nolan’s $19M 2023 pay with under-target performance shares (Sahm Capital, April 2024; Boston Globe, May 2026) — invites investor governance activism. (vi) Storm restoration reputation persists from Isaias 2020 (CTPost / NBC News, 2020) into 2024-26 dockets. (vii) Legacy 2019-2022 offshore-wind O&M commitments still trickle through the P&L. (viii) Rate-base model has negative incentive to accommodate DERs and VPPs. (ix) $26.5B five-year capex plan is credit-spread-sensitive at the new BBB+ rating. (x) Aging overhead distribution assets in CT and rural NH create ongoing storm-cost exposure.

Adjacent-segment play

The most interesting adjacent play is regulatory-facing utility software — the software layer that helps utilities like Eversource file better rate cases, run interconnection queues faster, and defend prudence dockets with better data. The addressable buyer set is the 300+ US investor-owned utilities, muni utilities and co-ops, each running fragmented, mostly in-house rate-case processes with Excel-plus-Word document assembly. A modern SaaS platform ingesting FERC Form 1 filings, state rate-case dockets, load-flow model outputs and prudence-review testimony can produce a rate-case-in-a-box product with seven-figure ACVs. Reference points: Tyler Technologies for local-government workflow, Neara for grid modeling, Bidgely for utility customer analytics. Eversource itself is a plausible customer given the volume of PURA / DPU / NHPUC / FERC dockets it runs annually.

A second adjacent is grid-edge insurance and warranty. As residential DER penetration climbs — solar plus battery plus EV charger — home warranty and property insurance are starting to price grid-connected assets. Kin (Florida), Cover Genius (embedded MGA), and Hippo have laid the infrastructure; a New-England-focused MGA covering DER performance, roof-mounted solar warranty and grid-outage business-interruption for small C&I customers would sit adjacent to but independent of Eversource. The Nolan / PURA political posture — every regulator, every AG, every consumer group is now pro-DER as a customer-side response to high delivery rates — is a tailwind for the adjacent, not for the incumbent.

A third adjacent is resiliency-as-a-service for New England municipal governments. CT and MA towns are politically active on utility rates and storm-restoration failures. A packaged offering combining town-scale battery storage, on-site solar at municipal buildings, microgrid controllers and a service contract — sold on the outcome of “town keeps power during Eversource outages” — has a discrete addressable market (~350 CT / MA / NH municipal governments) and premium pricing. Reference: Culdesac’s Tempe town-scale example (walkability rather than resiliency but the same municipal-buyer motion), Schneider Electric’s EcoStruxure microgrid business.

The wedge that does not generalise is head-to-head utility competition. Franchise monopolies are granted by law and are not disruptable by capital.
