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.

EIA Publishes Regional Electricity Supply and Pricing Forecasts Using UPLAN Model



LCG, August 13, 2019--The U.S. Energy Information Administration (EIA) announced that it is revising the presentation and modeling of its forecasts for electricity supply and market hub pricing to better reflect current electricity markets and system operations in the U.S. Beginning with the August 2019 Short-Term Energy Outlook (STEO), the new forecasting approach models electricity markets using the UPLAN production cost optimization software developed by LCG Consulting. EIA uses the solution results provided by this proprietary model to develop the STEO forecasts of monthly electricity generation, fuel consumption, and wholesale prices.

The new forecasts will generally correspond to electric power sector generation and fuel consumption for 12 electric supply regions, rather than using state boundaries that frequently do not correspond to market boundaries. The new electricity supply regions in the STEO better reflect how electricity is produced in balancing authority dispatch areas and wholesale markets. EIA is also beginning to forecast average peak-period wholesale electricity prices for the market hubs in the STEO electricity supply regions.

To incorporate the UPLAN model into the STEO, EIA also redesigned its Regional Short-Term Energy Model (RSTEM), which consists of an integrated system of equations and identities that link the various components of the U.S. energy industry together. RSTEM consists of submodules for each energy source (crude oil, electricity, coal, etc.) and industry function (production, demand, prices, etc.). The UPLAN model uses input data assumptions that are derived from EIA historical data sources and from other modules with RSTEM, along with data provided by LCG. The electricity supply modules within RSTEM use information from the UPLAN model solution output to create the published STEO electricity forecasts.
