Why This Matters
The completion of Bellefield 1 marks a major milestone in the U.S. transition to clean energy. Partnering with Amazon, AES is advancing the scalability of solar-plus-storage solutions, which are vital for meeting the energy demands of hyperscale data centers while supporting grid reliability. The 2,000 MW Bellefield project, once fully operational, will be the largest of its kind in the nation, capable of powering approximately 467,000 homes annually and displacing over 1 million metric tons of CO₂ per year. Innovations like AES' Maximo AI system and the creation of local union jobs further underscore the project's economic and environmental significance.
