National Grid's record £70bn investment plan and US AI power bet drive growth outlook

  • Record £70bn five-year investment plan National Grid will invest at least £70bn over five years, its largest ever, to connect up to 35GW of new generation and 19GW of new demand from data centres and electrification. This builds the asset base and supports 8-10% yearly earnings growth and rising dividends, pushing the shares up.

    This is the core new plan that directly drives future earnings and dividends, the main reasons investors hold the stock.

  • $1.75bn US AI power investment National Grid is investing $1.75bn for a 35% stake in Joulent, funding a 2.67GW gas-fired plant in Texas that will power a Microsoft data centre under a 20-year contract. This expands its US footprint and taps into the AI-driven electricity demand boom, a new growth driver.

    This is a new, concrete investment that opens a new growth market and is incremental to the £70bn plan.

  • UK grid upgrade costs up to £240bn The government now says Britain's grid needs up to £240bn of upgrades for net zero, far above earlier estimates. National Grid will deliver about £35bn of the £77bn planned by 2031, with more needed after. This means decades of regulated investment and earnings growth, though costs fall on consumer bills and face political criticism.

    This sets the long-term scale of National Grid's regulated investment opportunity, a key driver of its value.

  • Valuation debate after US investment After the Joulent deal, analysts say National Grid looks fairly valued on dividends (intrinsic value about £12.79, only 2.7% above the price) but cheaper than peers on earnings (19.1 times vs 22.7 times). The debate is whether heavy investment can grow cash flow without squeezing dividends.

    This gives a fair counterweight: the stock may not be cheap, and the investment phase carries risk to dividends.

Sempra's LNG growth hits a compressor snag while California wildfire liability risk resurfaces

  • ECA LNG Phase 1 first cargo shipped Sempra's ECA LNG plant on Mexico's Pacific coast sent its first cargo, a key step toward full operations. Long-term contracts with TotalEnergies and Mitsui underpin revenue, and the Pacific route cuts shipping time to Asia, supporting future earnings.

    This is a new operational milestone that directly supports Sempra's LNG growth story and future cash flow.

  • Compressor damage delays ECA LNG commissioning Sempra found damage in refrigerant compressors at ECA LNG Phase 1, pushing substantial completion to the fourth quarter. The delay is a setback, but the company still expects no reduction in planned 2026-2027 earnings, limiting the negative impact.

    This is a new operational problem that could delay revenue and adds uncertainty, directly affecting SRE's price.

  • Data center power demand forecast raised Goldman Sachs lifted its 2030 data center capacity forecast to 217 GW, naming Sempra among utilities set to benefit from rising power prices and new contracts. More data centers mean more electricity sales for Sempra's regulated utilities.

    This is a new analyst forecast that highlights a major demand driver for Sempra's utilities, supporting the bull case.

  • California wildfire bill sparks selloff and downgrades California lawmakers introduced a wildfire bill without liability protection for utilities, sending Sempra shares down 3.9% and prompting Mizuho to downgrade the sector. The bill could expose Sempra to large wildfire costs, a real regulatory risk.

    This is a new regulatory threat that directly pressures SRE's stock and adds long-term uncertainty.
