When Big Tech Buys the Power Station: Google's $4.75bn Intersect Deal and the Hyperscaler Energy Arms Race

CM Energy Insight — March 2026

In December 2025, Alphabet agreed to acquire Intersect Power — a clean energy and data centre infrastructure developer — for $4.75 billion in cash. It was not a power purchase agreement. It was not a partnership. Google bought the entire developer. That single transaction tells us more about where the global energy market is heading than any government white paper published in the last twelve months.

This article examines what drove the deal, places it alongside a wave of comparable moves by Microsoft, Amazon, and Meta, and asks what it all means for UK energy investors, developers, and policy-makers.

Why Google Bought a Power Company

Google was already a minority owner of Intersect and had closed a $20 billion partnership in 2024 to co-develop data centres alongside energy parks combining renewables and battery storage. The acquisition, however, represents something fundamentally different: vertical integration of the power supply chain into the tech company itself.​

Intersect's portfolio is substantial. The company has $15 billion worth of operating or under-construction infrastructure, with 10.8 GW of clean energy capacity expected to be operational or in construction by late 2028. The assets Alphabet will acquire include projects under construction in Texas and California, plus an in-development Texas complex with approximately 3.6 GW of solar and wind capacity and 3.1 GWh of battery energy storage.

The strategic logic is Intersect's "power first" co-location model. Rather than building a data centre and then waiting years for a grid connection, Intersect designs each project as a self-contained microgrid — solar, batteries, and flexible gas generation sitting on-site with the data centre, connected to the grid at the substation level but keeping most power flows internal. This bypasses multi-year interconnection queues, eliminates roughly 5% in grid transmission losses, and allows phased expansion without repeated permitting cycles.

Sheldon Kimber, Intersect's founder and CEO put it bluntly: "The truth is that modern energy infrastructure now sits at the center of American competitiveness in AI". Sundar Pichai framed it as operational necessity: Intersect will help Google "expand capacity, operate more nimbly in building new power generation in lockstep with new data center load".

The End of the PPA Era?

For a decade, hyperscalers treated power as a procurement problem. They signed long-term power purchase agreements with renewable developers, claimed "100% renewable" status through energy credit matching, and drew their actual electrons from the grid like everyone else.​

That model is breaking down. Google's emissions increased 51% from its 2019 baseline despite massive renewable procurement, driven by AI-related data centre growth. The grid simply cannot deliver new connections fast enough — US power project development timelines have stretched from under two years in 2000–2007 to more than four years for projects completed between 2018 and 2023. With over 40 GW of behind-the-meter and co-located generation now announced by hyperscalers collectively, the industry is moving decisively toward what developers are calling "Bring Your Own Generation" (BYOG).

Google's Intersect acquisition is the most dramatic expression of this shift, but it is not the only one. In the first two months of 2026 alone, Google signed PPAs with TotalEnergies for 1 GW of solar capacity in Texas, with Clearway Energy for 1.17 GW across Missouri, Texas and West Virginia, and with Xcel Energy for up to 1.9 GW of wind, solar and long-duration storage in Minnesota.

The Hyperscaler Energy Scoreboard

Google is not acting alone. Every major hyperscaler is now acquiring, building, or contracting energy assets at a scale that would have seemed fantastical five years ago. In 2025, Amazon, Google, Meta, and Microsoft together signed 16,777 MW of corporate renewables contracts — roughly 80% of all corporate renewable deals signed globally that year.​

The combined capital expenditure of the top five hyperscalers (Amazon, Alphabet, Microsoft, Meta, Oracle) is projected to exceed $600 billion in 2026, a 36% increase over 2025, with approximately 75% — around $450 billion — directly tied to AI infrastructure.​

The table below summarises the landmark energy deals each hyperscaler has struck in the last 18 months:

Nuclear's Comeback — Funded by Silicon Valley

Perhaps the most striking feature of this energy arms race is the rehabilitation of nuclear power — funded not by governments but by technology companies.

Microsoft's deal with Constellation Energy to restart the Three Mile Island Unit 1 reactor (rebranded the Crane Clean Energy Center) under a 20-year PPA drew global attention. The US Department of Energy subsequently approved a $1 billion loan to support the restart, with operations expected in 2027. Microsoft's Chief Sustainability Officer noted that carbon-neutral sources like nuclear will "increasingly contribute to achieving the 100% matching goal through 2030".

Meta went further in January 2026, signing three nuclear agreements — with Vistra, TerraPower, and Oklo — supporting up to 6.6 GW of energy by 2035. The TerraPower deal alone covers two advanced Natrium reactors at 690 MW, with rights to energy from up to six additional units totalling a further 2.1 GW. Meta described nuclear as essential for the "reliable, 24/7 clean energy" that AI workloads demand and that variable renewables alone cannot guarantee.

Amazon, meanwhile, has targeted more than 5 GW of new nuclear capacity before 2039, including a partnership with Energy Northwest on a small modular reactor project in Washington State. It has also invested in Talen Energy's existing nuclear capacity, acquiring the 960 MW Cumulus data centre campus adjacent to Talen's 2.5 GW Susquehanna nuclear station, and subsequently expanding its nuclear PPA with Talen to 1,920 MW through 2042.

NextEra Energy is restarting Iowa's Duane Arnold nuclear facility as a dedicated power source for a Google data centre, with Google paying for the plant directly — a textbook example of the BYOG model applied to nuclear.​

The White House Steps In

The scale of hyperscaler energy demand has become a political issue. On 4 March 2026 — just two days ago — President Trump convened executives from Amazon, Google, Meta, Microsoft, OpenAI, Oracle, and xAI at the White House to sign a "Ratepayer Protection Pledge".

Under the pledge, hyperscalers committed to "build, bring, or buy" all the energy needed for their data centres and to pay the full cost of associated grid infrastructure, ensuring those expenses are not passed on to residential ratepayers. Companies also agreed to negotiate separate rate structures with utilities, pay for energy capacity whether they use it or not, and make backup generation available to grid operators during periods of scarcity.

The pledge is nonbinding, but its political significance is real. It formalises the expectation that hyperscalers will self-supply rather than free-ride on existing grid capacity — an expectation already being built into state regulatory processes and FERC proceedings.

What This Means for the UK

The UK is not immune to these forces. Datacenter demand in the UK grid connection queue has reached 50 GW, while in Scotland alone, c5GW of data centre demand is currently in the planning system — exceeding Scotland's entire peak winter electricity demand of roughly 4,000 MW.

The government has designated AI Growth Zones and set a 6 GW data centre target, offering energy discounts of up to £24/MWh in Scotland and creating a new Connections Accelerator Service to fast-track grid access. National Grid's Data Centre Impact Study has explored behind-the-meter generation, private wire arrangements, and flexibility services as mechanisms to manage grid strain.

For UK energy investors and developers, the hyperscaler playbook creates both opportunity and risk:

• Grid connection reform becomes even more urgent. If hyperscalers follow the US BYOG model in the UK, they will seek behind-the-meter or private-wire arrangements that bypass the conventional connection queue — putting further pressure on NESO's Gate 2 process and the broader Connections Reform programme.

• BESS and flexibility assets gain new anchor tenants. Co-located battery storage is central to the Intersect model. UK developers with battery projects near data centre clusters (particularly in the Thames Valley, West London, and central Scotland) may find hyperscaler off-take is a faster route to revenue certainty than merchant trading.

• Nuclear and SMR interest intensifies. Every major hyperscaler has now signed nuclear deals in the US. As the UK's own SMR programme advances under Great British Nuclear and Rolls-Royce SMR, data centre co-location could emerge as a demand-side catalyst.

• The planning and consenting system faces new pressure. Hyperscale data centres with on-site generation are effectively industrial energy parks. The SSEP (Strategic Spatial Energy Plan) and CSNP (Centralised Strategic Network Plan), both due in 2027, will need to account for this converging demand.

The Bigger Picture

Google did not spend $4.75 billion on Intersect Power because it wanted to be in the energy business. It spent $4.75 billion because it concluded it could not win the AI race without controlling its own power supply. That calculation — now shared by Microsoft, Amazon, Meta, and increasingly by OpenAI, Oracle, and xAI — is reshaping the global energy investment landscape more rapidly than any climate policy, subsidy programme, or market reform.

For boutique energy advisory firms, for investors evaluating renewable or storage projects, and for developers navigating the UK's connection queue, the message is the same: the largest, most creditworthy, and most aggressive buyers of clean energy infrastructure in history are now in the market. Understanding their strategies is no longer optional — it is the starting point for every investment case.
