Fortum stock jumped after Alphabet’s Google agreed on September 15, 2026 to buy half of the Loviisa nuclear plant’s output in a 22-year deal. The utility’s recent quarterly figures show improved profitability and set the backdrop for the AI-driven demand story.

Fortum Oyj stock (ISIN FI0009007132) is trading higher after the Finnish utility secured a long-term nuclear power supply agreement with Alphabet’s Google, a deal that extends the life of its Loviisa plant and locks in demand for decades from 2030 to 2049, as reported on September 15, 2026.

Google data centers anchor Fortum’s nuclear output

According to Daily Finland on September 15, 2026, Fortum disclosed a 22-year supply pact that allows the extension of the Loviisa nuclear facility, with Google set to purchase 50 percent of the station’s electricity output between 2030 and 2049.

As Daily Finland reports, equities of Fortum surged more than 8 percent on the Helsinki Stock Exchange on the day the agreement was announced, reflecting investors’ view that the AI-linked demand from Google materially improves the utility’s earnings visibility.

Share reaction and AI-bubble commentary

A separate commentary from Placera.se on September 15, 2026 highlights that Fortum shares “rallied 17 percent or EUR 3 billion in market value” when the Google data center plans and the related power supply agreement were presented, underscoring how strongly the market reacted to the perceived AI-bubble tailwind.

For investors, the key takeaway from the Google deal is that a large portion of Fortum’s baseload nuclear output at Loviisa is now pre-contracted for two decades, which supports more stable cash flows and potentially underpins future dividend capacity compared with a scenario where volumes would have been sold purely on the wholesale market.

Strategic positioning in nuclear and AI demand

As Junior Stocks notes in a uranium sector piece dated September 15, 2026, Alphabet’s data centers will draw power from Fortum’s Loviisa nuclear plant under the new arrangement to support energy-intensive AI workloads, putting Fortum in a strategic position as a low-carbon baseload supplier to the global technology industry.

Historically, Fortum has focused on a combination of nuclear, hydro and other low-carbon generation in the Nordic region, and the Google contract amplifies this positioning by tying a portion of its nuclear portfolio directly to AI-driven demand growth, which many analysts see as a structural trend over the coming decade.

Recent financial performance provides context

In its most recent quarterly reporting before September 15, 2026, Fortum has shown improving profitability, with higher margins in its power generation and trading segments compared with the prior year period; these figures, covered by the company’s investor relations materials in 2026, provide the backdrop for understanding how incremental contracted nuclear volumes could translate into earnings stability.

Historical context from the company’s earlier financial reports indicates that in fiscal year 2024 Fortum generated several billion euros in revenue with a meaningful share coming from nuclear and hydro power, and management has emphasized the importance of long-term contracts and stable regulation for sustaining its return profile over time.

Risks and considerations for shareholders

Despite the clear positive signal from Google’s long-term commitment, there are still risks investors need to monitor, including regulatory decisions on nuclear plant lifetimes, potential changes in power market pricing, and the capital expenditure required to keep the Loviisa plant operating safely through 2049.

Another factor is the broader debate around how quickly AI-related electricity demand will ramp up and whether other utilities and energy technologies, such as renewables paired with storage, could compete with nuclear contracts, which could influence Fortum’s relative bargaining power in future negotiations.

Fortum stock price snapshot

On the Helsinki Stock Exchange, Fortum stock trades in euros and recently reflected the sharp move associated with the Google announcement, with the price move of more than 8 percent on September 15, 2026 marking a notable outperformance versus many other Nordic utilities on the same trading day.
