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.

Xcel Energy Reacquires NRG Spin-Off

LCG, Feb. 19, 2002--Xcel Energy has announced it wants to buy all outstanding shares of NRG Energy, which owns unregulated generating assets in the U.S. and other assets abroad.

NRG separated from Xcel in 2000, but has become highly leveraged and experienced significant risk of having its debt downgraded. Shares would be bought back at $11.50, 35 percent below their original pricing at issuance.

According to NRG, Xcel's announcement did not follow any negotiations between the two companies. Although Xcel has sought to strengthen NRG's position with transfers of capital and forced it to sell off overseas investments, NRG's stock price has fallen 50 percent in the past six months.

In communications with analysts, Xcel, which now owns 26 percent of NRG, asserted that its sudden announcement of a buyback at a discount was necessary to prevent a debt downgrade for the struggling unit. NRG's debt is currently investment grade. Credit Lyonnais Securities analyst Gordon Howald commented, "NRG's highly leveraged balance sheet proved unfixable in the near term."
