National Grid's U.S. Rate Squeeze: Why Rising Bills Are the Real Story
National Grid is a Northeast utility and stock-market story because rates, storms, and grid upgrades now collide.
Key takeaways
National Grid is a regulated utility story where customer bills, regulator approvals, and network investment are the same business model.
- National Grid serves more than 20 million people in New York and Massachusetts, making the U.S. Northeast its core American market (National Grid US).
- New York approved a three-year upstate delivery-rate plan on August 14, 2025, covering 2.3 million customers and about $5.3 billion of capital investment: $4.3 billion electric and $1 billion gas (New York PSC).
- Massachusetts gas rates remain under review after National Grid filed on January 16, 2026, with a DPU decision due by November 30, 2026 (National Grid Massachusetts filing).
- National Grid reported £11.576 billion of capital investment for FY2025/26 and now targets at least £70 billion of group capital investment through 2030/31 (National Grid 2025/26 results).
National Grid is an investor-owned energy company that delivers electricity and gas in the United States through regulated businesses in New York and Massachusetts. The paradox is sharp: the same upgrades meant to make the grid cleaner and more resilient are showing up as rate pressure, balance-sheet risk, and political friction. Customers read capital spending as delivery charges. Investors read it as rate-base growth. Regulators read it as an affordability test. The useful lens is the three R's: regulated returns, ratepayer tolerance, and resilience drag. When those move together, National Grid stops being a sleepy utility and becomes a live business story.
What is National Grid in the United States?
National Grid is a UK-based public utility group with U.S. energy businesses centered on New York and Massachusetts.
The keyword is easy to misread. In search, "national grid" can mean the broad electric system. In this Business & Finance context, it means National Grid plc and its U.S. utility operations. The company describes itself as one of the largest investor-owned energy companies in the U.S. and says it serves more than 20 million people across New York and Massachusetts (National Grid US).
Its utility economics come from regulated delivery networks: poles, wires, substations, gas mains, meters, storm response, and customer operations. State regulators decide how much of that spending can be recovered through rates. As of June 4, 2026, the upstate New York rate plan is approved, while the Massachusetts gas request remains in review toward a November 30, 2026 decision (New York PSC; National Grid Massachusetts filing).
Why are National Grid bills rising now?
National Grid bills are rising because delivery-rate cases are moving network costs from corporate plans into customer rates.
The New York Public Service Commission adopted a three-year rate plan for upstate National Grid on August 14, 2025, after cutting the company's first-year electric delivery revenue request by more than $340 million, or 67%, and its gas delivery revenue request by nearly $100 million, or 63% (New York PSC). Regulators can reduce the ask and still approve higher rates when reliability spending is judged necessary.
| Customer group | Status as of June 4, 2026 | Concrete rate signal |
|---|---|---|
| Upstate New York electric and gas customers | Approved three-year plan | Electric total revenue increases of 3.4%, 5.6%, and 4.6%; gas total revenue increases of 5.5%, 5.5%, and 6.0% across the three rate years (New York PSC) |
| Massachusetts gas customers | Pending DPU review | If approved, average winter monthly bill impacts of 8.4%, or about $24, in Boston Gas territory and 9.4%, or about $25, in Colonial Gas territory (National Grid Massachusetts filing) |
The friction is plain. Grid upgrades are sold as reliability, resilience, and decarbonization. Customers experience them as bigger delivery charges. National Grid's Massachusetts filing says the proposed gas adjustment affects only part of the gas distribution charge, not supply rates or state policy program charges (National Grid Massachusetts filing).
Why is National Grid a finance story, not just a utility story?
National Grid is a finance story because its earnings case depends on turning capital investment into regulated recovery.
For the year ended March 31, 2026, National Grid reported statutory operating profit of £5.431 billion, underlying earnings per share of 78.0 pence, and net debt of £44.160 billion (National Grid 2025/26 results). The company also reported £3.428 billion of capital investment in New York and £2.043 billion in New England for FY2025/26, using actual exchange rates (National Grid 2025/26 results).
That is the investor bargain. Capital spending can grow regulated assets and future earnings, but it can also lift debt and intensify rate scrutiny. National Grid says about two-thirds of its at least £70 billion capital investment plan is covered by regulatory agreements, leaving a meaningful slice still dependent on execution and approvals (National Grid 2025/26 results).
The myth correction: National Grid is not a pure renewables developer. Its FY2025/26 results say it completed the divestments of National Grid Renewables and Grain LNG, while its strategic progress section emphasizes regulated electricity and gas network investment (National Grid 2025/26 results).
What does the three-R framework say next?
The three-R framework says National Grid works when regulated returns, ratepayer tolerance, and resilience drag stay aligned.
First, regulated returns are the upside. National Grid targets around 10% compound annual asset growth from 2026/27 to 2030/31 and 8% to 10% underlying EPS compound annual growth from a 78.0 pence FY2025/26 baseline (National Grid 2025/26 results). More wires and pipes can mean more earnings, provided regulators allow recovery.
Second, ratepayer tolerance is the ceiling. The New York PSC reviewed nearly 9,000 public comments before adopting the upstate plan, and it framed the order around affordability, safe service, and just and reasonable rates (New York PSC).
Third, resilience drag is the weather bill. National Grid says U.S. major storm costs are recoverable through rate plans, but they are expensed as incurred under IFRS; in FY2025/26, deferrable storm costs were $52 million and below the company's $100 million threshold for exclusion from underlying results (National Grid 2025/26 results).
The structural backdrop is bigger than one company. The U.S. Department of Energy's 2023 New York fact sheet anticipated 3.4 GW to 6.3 GW of additional New York-New England transfer capacity by 2035, with a 5.2 GW median equal to a 255% increase relative to the 2020 system under a moderate-load, high-clean-energy scenario (DOE Grid Deployment Office). National Grid announced in May 2024 that roughly $35 billion of its five-year investment plan would go to Massachusetts and New York, more than 60% above its prior five-year regional investment (National Grid U.S. investment announcement).
The decision rule is blunt: the story works when capital spending, regulatory recovery, and customer patience stay aligned. It frays when any one breaks.
