Oklo and Siemens Energy Sign Agreement to Accelerate Power Conversion System for New SMR in Idaho

LCG, November 19, 2025--Oklo Inc. and Siemens Energy announced today that the parties have signed a binding contract for the design and delivery of the power conversion system for Oklo’s Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR). The agreement authorizes Siemens Energy to begin engineering and design work to expedite procurement of long-lead components and to initiate the manufacturing process for the power conversion system. Oklo’s expertise in advanced fission technology will be combined with Siemens Energy’s extensive industry experience with steam turbine and generator systems, with the ultimate goal of generating carbon-free, reliable electricity.

NERC's New Winter Reliability Assessment Raises Concerns for Elevated Risk of Insufficient Supplies to Meet Demand in Extreme Operating Conditions

LCG, November 19, 2025--NERC yesterday released its 2025–2026 Winter Reliability Assessment (WRA), which concludes "much of North America is again at an elevated risk of having insufficient energy supplies to meet demand in extreme operating conditions." The WRA does state that resources are adequate for normal winter peak demand, but extended, wide-area cold snaps will be challenging.

California Takes a Bath on Surplus Power

LCG, July 18, 2001The state of California is selling surplus electric power and losing money perhaps a lot of money on every megawatt-hour, according to a report in this morning's issue of the San Jose Mercury-News.

All year long, the state, through the California Department of Water Resources, has been purchasing power, often at top prices, in an effort to stave off rolling blackouts during the summer. With the arrival, a number of factors have combined to give the state a surplus.

The weather has cooperated to a marked degree, with peak demand much less than predicted. In addition, power plants owned by independent generators have been reliable following maintenance over the winter and three large new generating stations have begun producing electricity. On top of that, Californians have been answering the call to conserve power spurred by the specter of higher prices.

"We're seeing certain times of the day where we may not need power that we previously thought we needed, and we're selling it on the open market," Oscar Hidalgo, spokesman for the water agency told the Mercury-News. "We're probably moving a little more power than we anticipated, but I don't think anybody anticipated a July like we're experiencing."

The California Independent System Operator has daily been reporting around 42,000 megawatts of power available while demand has been far lower. Today, for example, Cal-ISO expects demand to reach 32,210 megawatts, meaning a surplus of around 10,000 megawatts.

Because electricity can't be stored, the state has been obliged to sell its surplus for whatever it can get, which in some cases hasn't been much.

"There's a painful lesson to be learned when you overbuy when supplies are tight," Gary Ackerman, executive director of the Western Power Trading Forum, told the paper. "Anybody can lose money in this business, and the state of California is getting a taste of that."

According to California Energy Markets, a trade weekly, the state was selling power last Thursday at $25 per megawatt-hour. Ackerman said the state has been selling power for as little as $1 to $5 per megawatt-hour. Power was selling on the spot market for $20 to $40 per megawatt-hour yesterday.

Whether the state planned well or overbought is hard to say, the Mercury-News observed. The contracts could prove invaluable if another heat wave threatens blackouts. Ackerman likened power contracts to insurance -- a prudent move to guard against shortages and price spikes, even if it turns out you don't need it.
