Overview

Amazon has been reaffirmed by BloombergNEF as one of the world’s leading corporate buyers of carbon‑free energy for 2025. The company now oversees a portfolio that exceeds 40 GW of renewable, nuclear, and storage capacity across more than 700 projects in 28 countries. Sellers on Amazon should watch these developments because they shape electricity costs, grid reliability, and the sustainability credentials that buyers increasingly demand.

Key Points

• Top corporate purchaser — BloombergNEF ranks Amazon among the highest global buyers of carbon‑free power for the second consecutive year.
• 40 GW installed — Amazon’s investments total over 40 GW, enough to supply roughly 12.1 million U.S. homes.
• 700+ projects — The portfolio spans four nuclear agreements, 11 utility‑scale battery farms, 300+ utility solar and wind sites, 300 onsite solar installations, and six offshore wind farms.
• Mississippi data‑center boost — A partnership with Entergy adds 650 MW of renewable capacity, enough for more than 150 000 homes, and funds a $300 million grid‑reliability program at no cost to residential customers.
• SMR rollout — Amazon is backing four small modular reactors (SMRs) in Washington (initial 320 MW, expandable to 960 MW) and has committed $500 million to X‑Energy to develop over 5 GW of new nuclear capacity by 2039.
• Battery‑storage intelligence — At the Baldy Mesa project, AI analyzes up to 33 billion data points annually to decide when to store or release power, smoothing supply during heat‑wave peaks.

How Amazon’s Carbon‑Free Energy Strategy Works

1. Long‑term power purchase agreements (PPAs) — Amazon signs multi‑year PPAs with developers, guaranteeing revenue that lets projects secure financing and begin construction. Example: a 15‑year PPA for a 300 MW wind farm in Texas.
2. Project diversification — The company spreads investments across nuclear, solar, wind, and battery storage to balance baseload reliability with intermittent generation.
