- National Grid’s distribution business rolled out its new Network Development Plan, laying out projections for the next decade on local grid demand and added power connections.
- The plan lives within a digital map that highlights network “headroom,” existing constraints, and potential remedies—flexibility services, traditional reinforcement, or operational tweaks all mapped out. National Grid
- National Grid ended Friday up 0.33%, even as the FTSE 100 slipped 0.4%. With full-year results coming on May 14, investors are watching the company closely.
National Grid plc’s distribution arm has rolled out its 2026 network plan, throwing a spotlight on a longstanding UK power market headache—just where fresh demand, renewables, and battery projects find room to connect.
That’s suddenly a big deal, with National Grid pitching those grid bottlenecks as a regulated growth angle. Shares barely budged on Friday. The update lands just days ahead of full-year results—a moment that should reveal how much patience investors have for upfront U.S. costs.
National Grid Electricity Distribution’s Network Development Plan, or NDP, outlines how the company aims to shape its local power network over the next decade. Distribution here refers specifically to the lower-voltage lines that move electricity from the national transmission grid out to households, commercial sites, and community initiatives. The company states these plans are a licence requirement and need to be refreshed and published every two years.
The updated map pulls together a snapshot of both current and future capacity—industry calls this headroom—spanning bulk supply, primary, and distribution substations. Users can spot constraints and see projected fixes stretching out a decade. Flexibility services boil down to this: the grid pays users or operators to move demand or supply around, sidestepping or deferring the need for bigger upgrades.
National Grid says it’s shifting planning outputs—previously stuck in static reports—into what it calls a “fully interactive digital experience.” Oliver Spink, who heads up system planning at National Grid DSO, added that the new approach is aimed at “unlocking economic growth,” pointing to more transparent, responsive ways of network planning.

The operating update arrives as National Grid ramps up capital spending. Back in March, the company outlined plans to pour at least 70 billion pounds into its business through fiscal 2031 and agreed to the RIIO-T3 framework—the UK’s price-control setup for electricity transmission revenues and returns, covering the period from 2026 to 2031. National Grid said this strategy should drive group asset growth to roughly 10% per year, and underpin underlying EPS growth of 8% to 10% annually from a fiscal 2026 baseline.
One wrinkle in the short term: National Grid’s April update confirmed full-year performance through March 31 met expectations. Still, the company pointed to roughly a 1 pence-per-share reduction in underlying earnings, citing customer refund charges from a U.S. Federal Energy Regulatory Commission ruling on New England Transmission, plus a small uptick in U.S. storm-related costs.
Morningstar’s Tancrede Fulop flagged that the one-off items are set to trim fiscal 2026 EPS by around 1.3%, but said the business overall is still tracking prior guidance. Fulop left his fair-value estimate unchanged at 1,440 pence and called the stock moderately undervalued.
Competition’s not straightforward here. SSE and Centrica both face the UK energy transition, but National Grid stands apart: its fortunes hinge on regulated infrastructure, not so much on generation or selling power to customers. “National Grid is in a strong position to make long-term capital spending decisions and its assets look attractive,” said David Harrison, fund manager and head of sustainability at Rathbones Asset Management.

Still, the bet comes loaded with risk. Grid projects demand hefty capital, making them vulnerable if interest rates climb, inflation bites, building lags, rules shift, or demand for connections misses the mark. In a recent Morningstar note, Fulop cautioned, “it’s not a simple one-way trade.” Morningstar
Eyes now on May 14—that’s when Chief Executive Zoë Yujnovich and CFO Andy Agg face investors post-results. The headline figures count, but the messaging might weigh just as much. For National Grid, it’s about proving that a push for public grid data, speeding up planning, and scaling up regulated investments can actually boost earnings, all without overburdening customer bills or stretching the balance sheet excessively.
