Amazon Approved to Acquire 1.2GW Sunstone Solar-Plus-Storage Project in Oregon

Global technology giant Amazon has received approval to acquire the 1.2GW Sunstone solar project in Oregon, one of the largest solar photovoltaic (PV) developments in the United States.

The Sunstone project was developed and previously owned by US independent power producer Pine Gate Renewables, which filed for bankruptcy in November 2025. The site comprises 1.2GW of solar PV capacity paired with 1.2GW of battery energy storage system (BESS) capacity. The project is considered “ready to build”, having secured all necessary permits and approvals from the Oregon Energy Facility Siting Council (EFSC).

Amazon’s acquisition was approved by the Bankruptcy Court for the Southern District of Texas. The company will purchase the project for US$83 million in cash through its dedicated project subsidiary, Oregon Solar I.

The move comes after Amazon raised concerns in November over insufficient power supply from an Oregon utility to support its expanding data centre operations in the state. Amazon has built multiple cloud computing data centres near the Columbia River, significantly increasing its electricity demand in the region. Once fully operational, the Sunstone solar-plus-storage project is expected to rank among the most significant renewable energy generation assets in the US.

Historically, Amazon has met most of its energy needs through power purchase agreements (PPAs). Alongside fellow tech giants Meta and Google, Amazon led US solar power procurement in 2024. However, the scale of the Sunstone project, combined with its advanced development status, makes it particularly attractive as Amazon’s energy demand continues to grow rapidly.

As electricity consumption from data centre hyperscalers rises, direct ownership of power generation assets may become increasingly common. Last month, Alphabet, Google’s parent company, announced the acquisition of energy developer Intersect Power. At the time, Alphabet and Google CEO Sundar Pichai said the move would allow the company to develop new energy capacity “in lockstep with new data centre load”.

Since filing for bankruptcy, Pine Gate Renewables has put approximately 10GW of project assets on the market, while maintaining that it has sufficient liquidity to continue operating. Earlier this month, Israel-based developer Nofar Energy acquired 1GW of Pine Gate’s utility-scale solar assets across the Carolinas, Alabama and Texas for US$285 million.
