LONDON, April 22, 2026, 18:15 BST
- National Grid reported that a 150-tonne transformer has arrived at its Exeter substation.
- UK ministers rolled out a fresh plan Tuesday aimed at slashing grid constraint costs.
- Shares finished up. Still, near-term pressure comes from U.S. storm expenses and a FERC decision.
National Grid plc said Wednesday it delivered a 150-tonne transformer to its Exeter substation. The drop-off comes as Britain urges utilities to speed up grid upgrades, with the company marking the installation as a local milestone.
Timing isn’t accidental. Just the day before, the UK government rolled out its Reformed National Pricing plan—a set of electricity market tweaks targeting constraint costs, those payments triggered when power can’t get from generator to consumer. Officials claim the changes will cut system costs, boost efficiency, and make the grid run more smoothly.
National Grid closed up 1.67% at 1,274.8 pence in London, Sharecast data show, bucking the weaker tone across the wider market. Investors continue to treat the utility less as a steady bond stand-in and more as a regulated infrastructure name facing hefty capital demands.
The company says the new Exeter equipment should bolster both resilience and capacity for the South West’s transmission network. It’s calling the device a static compensator transformer—a type of substation equipment designed to keep voltage steady and allow electricity to move safely through the grid.
National Grid project manager Jacob Demuth described the delivery as “a real team effort,” adding that the unit is set to bolster “resilience and future stability” for the region’s network. Devon County Council noted it took over four years just to plan the route. National Grid
It’s a minor project within National Grid’s broader investment push—and that’s exactly the idea. Britain faces the need for a massive number of upgrades like this, big and small alike, to link up new wind, solar, batteries, data centers, and more electric vehicles, all while keeping system-balancing costs under control.
The delivery plan from the government puts potential network constraints at close to 7 billion pounds in 2030. Extra steps outlined could trim as much as 1 billion pounds off that figure in the same year. The plan also points to analysis from National Energy System Operator: pulling forward three transmission projects from 2031 to 2030 might shave around 4 billion pounds from constraint costs in 2030.
Competition is closing in. According to Argus, National Grid, SSE, and SP Energy Networks have committed to deploying dynamic line rating—technology that leverages real-time weather and temperature data to assess a line’s power capacity, moving past fixed thresholds. Argus also points to NESO forecasts suggesting this could save consumers as much as 400 million pounds by 2030.
Investors face a slightly less murky earnings outlook, but the pressures remain. National Grid reported on April 13 that its full-year performance to March 31 matched forecasts, although underlying earnings per share are set to take about a 1 pence net knock. The drag comes from customer refund charges following a March 19 ruling by the U.S. Federal Energy Regulatory Commission on New England Transmission, plus higher-than-anticipated storm costs in its U.S. operations.
National Grid will release its full-year numbers on May 14. Chief Executive Zoë Yujnovich and CFO Andy Agg are set to address investors after the figures drop. Back in March, Reuters said the company sees adjusted earnings per share rising 13% to 15% by 2027, driven by a fresh regulatory period and more room for revenue.
Execution is front and center here. Under Ofgem’s RIIO-T3 rules—a five-year regime kicking off in April 2026 and running through March 2031—National Grid’s electricity transmission unit can target a real cost of equity of 6.12% with 60% gearing. Actual returns, though, will hinge on how well projects are delivered, whether costs get recovered, and if the regulatory incentives hold up. Back in December, National Grid said it would review if the final set of rules stacked up as both “investable” and “workable.” National Grid
Views are split. Back in March, Jefferies’ Ahmed Farman cut his rating on National Grid to Hold, moving down from Buy. He pointed to the stock’s sector-high valuation, flagged a lack of regulatory drivers through the end of the year, and called out elevated real rates as a drag on sentiment.
