Tesla has entered into a long-term Power Purchase Agreement (PPA) with the Madrid-based renewable energy firm Zelestra to acquire the entire electricity output of a forthcoming 140 MW solar energy project in Texas. The facility, dubbed the Lumen solar farm, will be situated in Anderson County within the Electric Reliability Council of Texas (ERCOT) market.
According to the official announcement from Zelestra on July 29, 2026, construction on the site is slated to commence in 2027. The company expects the plant to reach full operational capacity by 2029. This agreement represents a significant expansion of the partnership between the two firms; they previously collaborated in 2024 on a 57 MW PPA involving solar installations in Spain’s Castilla-La Mancha region.
Phil North, CEO of Zelestra US, stated that the project is intended to support Tesla’s rapidly increasing energy requirements in the Texas region. The deal underscores Tesla’s ongoing strategy to secure direct, large-scale renewable energy supply to power its manufacturing and operational infrastructure.
