The statement is assessed as highly likely to be true based on overwhelming and consistent evidence from primary and secondary sources. The two principal parties, NextEra Energy (the plant operator) and Google (the customer), have both issued official public announcements confirming their collaboration to restart the Duane Arnold Energy Center in Iowa. Google's official blog post explicitly states the purpose is to supply carbon-free power for its data centers. This core claim is directly and independently verified by numerous highly authoritative news outlets, including Reuters, CNBC, and major local Iowa newspapers like The Des Moines Register and The Gazette. There is no conflicting evidence among the provided sources. The confidence in this assessment is high due to the quality and unanimity of the sources. The truth probability is set slightly below 1.0 because the restart is a future plan, with reports citing a target date of 2029. While the agreement and intent are firmly established, the successful completion of a major energy project years in the future is not absolutely guaranteed and is subject to regulatory, financial, and logistical execution.
