Overview

• From June 2027, Meta will acquire the Clinton plant’s full 1.1 gigawatts of nuclear-generated electricity under a 20-year contract.
• The agreement replaces Illinois’ expiring zero-emission credit subsidy and underwrites the facility’s relicensing process through at least 2047.
• Constellation plans a 30-megawatt capacity uprate, with the pact expected to generate $13.5 million in annual tax revenue and $1 million in nonprofit grants over five years.
• Meta’s first nuclear power deal underscores a broader tech trend of securing reliable, low-carbon energy to meet growing AI and data center demands.
• Constellation is evaluating a permit application for a small modular reactor at the Clinton site to further expand nuclear capacity.
