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 and data center gains offset by wildfire liability risk

ECA LNG first cargo and data center demand Sempra's ECA LNG project shipped its first cargo under long-term contracts, while forecasts for data center electricity demand rose, boosting confidence in future growth.
This is a major new operational milestone and demand driver for Sempra.
Earnings beat and raised guidance Sempra reported $796 million in profit, beating guidance, and raised its full-year targets, signaling strong financial performance.
This is a new positive financial result that directly impacts investor sentiment.
Funding $65B buildout via asset sales and deals Sempra funded its $65 billion buildout through asset sales, including an Ecogas Mexico sale and a KKR stake deal, plus a 20-year Petrobras LNG contract.
This shows how Sempra is financing its growth, a key new development.
Wildfire bill and LNG delays A California wildfire bill without utility liability protection caused a 3.9% selloff and downgrades, while compressor damage delayed ECA LNG completion to Q4.
This is a new negative event that pressured the stock during the quarter.

Sempra beats guidance, sells assets, signs Petrobras LNG deal

Profit jump and raised guidance Sempra's second-quarter profit rose to $796 million from $461 million a year earlier, and the company lifted its full-year earnings guidance to $4.80-$5.30 per share while keeping a 7%-9% long-term growth target. Higher expected earnings make the stock more attractive to buyers.
Earnings growth and raised guidance are the core fundamental driver of the stock's value.
Asset sales fund $65 billion buildout Sempra completed the roughly $500 million sale of its Ecogas Mexico gas business and is selling a 45% stake in Sempra Infrastructure to KKR. The cash helps pay for its record $65 billion five-year plan, mostly regulated utility projects, without selling more new shares that would dilute owners.
Capital recycling reduces dilution risk and supports the growth plan that underpins future earnings.
20-year Petrobras LNG contract Sempra signed a 20-year deal to sell about 800,000 tonnes of LNG a year to Brazil's Petrobras from its Port Arthur Phase 2 project in Texas. Locking in a long-term customer supports the roughly $12 billion expansion and future cash flow.
A long-term sales contract de-risks a major growth project and supports future revenue.
Rising US gas costs and new financing mix Industry speakers warned that climbing US natural gas prices could make American LNG less competitive globally, a risk for Sempra's export projects. Sempra also said it is leaning more on private-equity and sovereign-wealth funding for expansion, which can be costlier or more complex than traditional loans.
This is the main counterweight: cost pressure on LNG margins and a shift in how projects are financed.

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.
