London, July 14, 2026, 10:12 (BST)
National Grid plc (LON:NG) shares traded around 1,242 pence on Tuesday ahead of its 11:00 BST annual meeting, where shareholders are due to adopt updated articles carrying a £70 billion group borrowing limit, up from £55 billion. The higher ceiling was approved at the 2025 AGM, so Tuesday’s resolution implements an earlier vote rather than unveiling fresh financing.
The timing matters. The legal ceiling is separate from National Grid’s plan for at least £70 billion of capital expenditure over the five years through March 2031—capex means money spent on long-lived assets—but the identical headline numbers put leverage back in view. Net debt reached £44.2 billion at end-March from £41.4 billion a year earlier, while management expects underlying earnings per share to rise 13%-15% in the year to March 2027.
On a risk-off morning, National Grid was roughly flat, trailing network-heavy peer SSE plc (LON:SSE) but outperforming a falling FTSE 100. At about 09:45 BST, the comparison was:
| Security or index | Indicative price/level | Session move |
|---|---|---|
| National Grid plc (LON:NG) | 1,241p | Flat |
| SSE plc (LON:SSE) | 2,459p | +0.9% |
| FTSE 100 | 10,445 | -0.5% |
More revealing is what happened after July 1: the shares dropped 37p between the June 30 and July 1 closes, when National Grid announced a $1.75 billion purchase of 35% of Joulent, then recovered 31p by Tuesday’s 1,242p reference price—84% of the loss. Chief Executive Zoë Yujnovich called Joulent a “disciplined, partner-led investment”; the cost sits outside the £70 billion programme and is to be met from balance-sheet headroom. The rebound suggests investors currently see it as a contained side bet, rather than a shift away from regulated networks—an inference from the price action. Investing.com
That reading fits the capital map. Roughly £69 billion, or 98.6%, of the disclosed programme sits in four regulated-network buckets, leaving about £1 billion for National Grid Ventures. Yujnovich called it “the largest investment programme in our history”; about two-thirds is already covered by regulatory agreements. National Grid
| FY2027–FY2031 investment bucket | Planned capex | Approximate share |
|---|---|---|
| UK Electricity Transmission | £31bn | 44.3% |
| New York regulated networks | £17bn | 24.3% |
| New England regulated networks | £12bn | 17.1% |
| UK Electricity Distribution | £9bn | 12.9% |
| National Grid Ventures | £1bn | 1.4% |
Valuation leaves room, not unanimity. A July 2 consensus snapshot counted nine positive ratings, six holds and two sells; 13 price targets had a 1,377p median, about 11% above Tuesday’s price, while the 1,060p low case implies roughly 15% downside. Keith Bowman of interactive investor wrote in May that National Grid offers “five-year financial predictions which few other companies can,” while flagging regulatory and currency uncertainty.

Fresh system data make the spending case tangible. Craig Dyke, director of system operations at the National Energy System Operator, said extreme heat during the week beginning June 22 created “tight operating margins”; no customer demand was disconnected, and grid frequency remained between 49.66 and 50.23 hertz, inside statutory limits of 49.5 to 50.5. Frequency—the grid’s 50-hertz heartbeat—shows whether electricity supply and demand are balanced. National Energy System Operator (NESO)
NESO is now publicly owned and separate from National Grid: it runs Britain’s electricity system, while National Grid Electricity Transmission owns and maintains the high-voltage network in England and Wales. That distinction means the heat episode was not a National Grid control-room failure, though the network constraints still reinforce the case for investment in cables, substations and transformers.
But the same pressure creates execution and reputation risk. A north Devon community solar farm was shut for the summer; its owners estimate £2 million of lost revenue, while delayed equipment is now due in September. Repeated curtailments or project slippage could bring tougher regulatory scrutiny and higher costs as National Grid’s spending reaches record levels.
The next checks arrive quickly: AGM results later Tuesday, payment of a 32.14p final dividend on July 23 if approved, and fiscal first-half results on November 5. For investors, the central question is not whether grids need capital. It is whether National Grid can turn record outlays into allowed returns without pushing debt higher than planned or letting Joulent expand the unregulated risk budget.
