(TRISO stands for TRi-structural ISOtropic).

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.

PNM Asks Court to Rule on Western Resources Merger

LCG, Oct. 15, 2001--Public Service Co. of New Mexico asked a New York court on Friday to either rewrite the terms of its takeover of two Kansas utilities from Western Resources Inc., or to call a halt to the pending transaction.

Western Resources and PNM announced the $4 billion deal last November, in an arrangement that would required Western to separate its electric utilities from the parent company and spin off its other businesses to shareholders.

But the Kansas Corporation Commission in July of this year Rejected Western's request for an electric rate increase and blocked the company's reorganization plan. That, according to PNM, changed the terms of its agreement with Western.

Western, though, is still trying to push through the deal with PNM, despite the New Mexico utility's claim that the deal is now much different that the one it agreed to. PNM has now taken the matter to the Supreme Court of New York, where both companies agreed to take any disputes.

"Although we take this step reluctantly, we believe we have no choice," said Jeff Sterba, PNM chief executive. "Western has demanded that we seek KCC approval of the original transaction, even though it contains a provision that has now been ruled unlawful by the KCC. We believe it would be futile for us to make such a filing."

Sterba added "We believe the current agreement must be restructured, so that it can be approved by the KCC."

PNM is a combined electric and gas utility serving about 800,000 million customers in New Mexico. Western provides electricity to about 636,000 customers in Kansas.
