SSE PLC Stock: Why Investors Are Watching Its £33bn Grid Bet Before May Results

SSE PLC Stock: Why Investors Are Watching Its £33bn Grid Bet Before May Results

May 1, 2026

London, May 1, 2026, 19:03 BST

SSE PLC on Friday reported its total voting rights at 1,212,191,770, according to a regulatory filing. That number reflects the subtraction of 3,282,272 treasury shares—held by the company and not entitled to a vote—from its 1,215,474,042 issued ordinary shares. Investors use this figure as the baseline for UK holding disclosures.

Norges Bank bumped above a key ownership threshold in SSE this week, according to a separate filing. The Norwegian central bank reported a 3.151730% stake in voting rights—made up of 36,468,666 votes from shares it holds, plus another 1,736,146 from recallable shares on loan.

Notices come ahead of SSE’s preliminary results due May 28, where investors will zero in on how it plans to finance grid and renewables growth. In its April trading update, SSE pointed to adjusted earnings per share for 2025/26 in the 147p to 152p range, capital investment of about £3.5 billion, and adjusted net debt plus hybrid capital — those instruments that blend debt and equity characteristics — just topping £10 billion.

SSE shares finished Friday at 2,619.00 GBX, according to the company’s investor page. On Thursday, MarketWatch noted the stock jumped 2.98% to £26.41, topping the FTSE 100’s 1.62% gain. Shares remain under their April 13 high.

The main challenge here: the scale of expansion. SSE’s SSEN Transmission unit is pushing ahead with a north of Scotland power transmission program topping £29 billion, with 11 flagship projects at the core. Five of those are under construction now, according to the company, and over three-quarters of the necessary consents are already in hand. SSE controls 75% of SSEN Transmission.

The battle’s playing out in regulated grid investment, not the retail energy sphere. According to Ofgem, RIIO-3—the regulator’s five-year price control for monopoly networks, from April 2026 through March 2031—determines both earnings and investment limits. National Grid’s RIIO-T3 proposal? That would almost double its electricity transfer capacity across Britain.

SSE took the opportunity on Friday, with the Montrose announcement, to keep the spotlight on renewables. The Duke of Edinburgh stopped by Seagreen’s O&M base at Montrose Port, and SSE pointed out that Seagreen stands as Scotland’s largest operational offshore wind farm. Chief Executive Martin Pibworth called it a source of “secure, home-grown clean power.” Seagreen’s general manager Ewan Latimer pointed to the sector’s ability to “support ports, create skilled jobs.” SSE

Still, it’s not a one-way street. SSE keeps its investment-grade profile — S&P at BBB+, Moody’s Baa1, Fitch also BBB+ — all holding stable outlooks on the investor page. Fitch, however, flagged that with current capital spending plans, FFO net leverage could climb close to 5.0 times by fiscal 2030. If delays hit projects, expenses jump, or allowed returns fall short, that’s the cushion investors will be eyeing.

The voting-rights filing leaves earnings untouched for now but offers a clearer look at the shareholder base of a company whose valuation depends on pushing a major, regulated build-out from blueprint to execution.

  • Istanbul Airport Moves Ahead of Heathrow for Europe's Top Spot in July 2025
    August 11, 2026, 4:21 AM EDT. Istanbul Airport handled 8.15 million passengers in July 2025, pushing it past London Heathrow, which counted 7.86 million in the month. Heathrow saw Middle East route traffic fall 20.2% year-on-year, hit by the ongoing US-Israel-Iran conflict. The airport, which led Europe from 1996 to 2019 and again from 2023, is still running close to full with just two runways and is pressing for a third to reach up to 150 million passengers a year. First half numbers show Heathrow at 84.46 million travelers in 2025, with demand staying high despite the hit on some routes. It has also raised airline fees as it tries to fund early work on that new runway.
