Alphabet buys Intersect Power to secure AI data center energy

On Monday, Google parent Alphabet announced that it has agreed to acquire Intersect Power, a developer of data centers and clean energy. The transaction is valued at $4.75 billion in cash, in addition to the assumption of the company’s outstanding debt. Under the terms of the agreement, the acquisition will include Intersect Power’s future development projects. However, it excludes the developer’s existing operation, which is set to be bought out by other investors and managed as a separate company.

The acquisition is designed to help Alphabet expand its power-generation capacity alongside new data centers. This allows the company to bypass local utilities, which are regional power providers currently struggling to keep up with the massive energy demands of artificial intelligence companies. Securing direct access to the energy that powers these data centers has become a critical factor for companies training and running AI models.

Alphabet previously held a minority stake in Intersect Power, following a strategic funding round led by Google and TPG Rise Climate. The financial details of the partnership and acquisition include:

• $4.75 billion in cash, plus debt assumption, for the acquisition.
• $800 million for the previous strategic funding round led by Google and TPG Rise Climate.
• $20 billion in total investment targeted by the partnership by 2030.

Google will be the primary user of the new data parks, which are locations situated next to wind, solar, and battery power designed to host AI chips. However, Intersect Power’s campuses are designed as industrial parks, meaning they can also host other companies’ AI chips alongside Google’s own hardware.

According to Google, these new data parks are expected to be operational late next year and are projected to be fully completed by 2027. The transaction itself is expected to close in the first half of next year.

Why it matters

Big Tech is shifting from being a customer of the energy grid to owning the infrastructure that generates power, as grid bottlenecks become the primary constraint on AI scaling. By acquiring its own clean energy developer, Alphabet is securing the massive power capacity required to run its AI infrastructure independently of regional power grids, highlighting how direct energy access has become a critical operational priority.
