NextEra Energy and Google Collaborate on Accelerating Nuclear Power Deployment

LCG, October 28, 2025--NextEra Energy and Google yesterday announced two agreements that will help meet growing electricity demand from artificial intelligence (AI) with clean, reliable, 24/7 nuclear power and strengthen the nation's nuclear leadership. First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

PSEG Takes Controlling Interest in Tunisia Power Plant

LCG, Dec. 27, 2000Newark, N.J.-based PSEG Global Inc. and Marubeni Corp. of Japan announced jointly yesterday that they had acquired from Sithe Energies Inc. the interest they didn't already own in Carthage Power Co., an ad hoc Sithe unit set up to own and operate a 471 megawatt power plant in Tunisia.

PSEG Global increased its ownership in Carthage Power from 35 percent to 60 percent and Marubeni increased its shareholding from 32.5 percent. PSEG will assume Sithe's contract rights and obligations for management of construction and ongoing operation and maintenance of the plant.

Michael Thomson, president of PSEG Global, said "We have seen greater return and more efficientoperations in assets we control than in ones where we simply are a minority partner. This is part of alarger strategy to increase our ownership in select projects around the world."

The plant is scheduled to begin commercial operation next summer. Natural gas fuel for the combined-cycle facility will be furnished by Socit Tunisienne d'Electricit et du Gaz, the Tunisian energy utility, which will also contract for the plant's electric output.

Financial terms of the sale were not disclosed.
