Meta has signed a power purchase agreement with renewable energy company Zelestra, expanding its U.S. solar portfolio. The deal builds on an existing partnership between the two firms, which are backing several solar projects across the country.

Under the PPA, Meta will offtake electricity from solar installations developed by Zelestra, though specific capacity or pricing figures were not disclosed. The arrangement adds to Meta's growing portfolio of renewable energy contracts aimed at powering its data centers and operations.

Zelestra, a global renewable energy developer, has been scaling its U.S. presence through corporate PPAs. For Meta, the agreement supports its goal of matching 100% of its electricity consumption with renewable energy, a target the company says it has met since 2020.

The solar projects are located across multiple U.S. states, but exact locations and timelines were not specified in the announcement. Construction and operational details remain undisclosed.

Corporate PPAs like this one are a key driver of U.S. solar deployment, accounting for a significant share of new capacity in recent years. However, interconnection delays and supply chain constraints continue to pose challenges for project timelines across the sector.
