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.

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.

Mississippi Power and Sierra Club Achieve Settlement Agreement on Select Coal Assets
LCG, August 6, 2014-Mississippi Power, a subsidiary of Southern Company, announced Monday a settlement agreement with the Sierra Club that will reduce coal-fired power generation at three of Mississippi Power's older coal plants. The Sierra Club agrees to dismiss and withdraw all pending legal and regulatory challenges against Mississippi Power's Kemper County project and Plant Daniel and refrain from formally intervening in all existing and anticipated regulatory proceedings for these two plants for a period of three years.
Plant Ratcliffe, located in Kemper County, Mississippi, is a 582-MW IGCC (Integrated Gasification Combined Cycle) project. The state-of-the-art facility is designed to capture approximately 65 percent of the carbon dioxide emissions, which will then be compressed and transported via a new, 61-mile pipeline to inject underground and support Enhanced Oil Recovery (EOR) operations. In December 2010, Mississippi Power held the ground breaking ceremony for the project, which is now scheduled to commence generating power in 2015.
Plant Daniel is a 2,077 MW, four unit fossil fuel power plant located in Escatawpa, Mississippi. A $660 million scrubber project is currently under way to ensure compliance with the new federal environmental standards by April 2016. After the upgrades are complete, 95 percent of the plant's sulfur dioxide emissions are expected to be removed.
To most economically comply with new federal environmental standards and meet the company's obligations under the settlement agreement, Mississippi Power plans to repower, convert to natural gas, or retire several units at plants Watson, Sweatt and Greene County. At Plant Watson, Mississippi Power will terminate the use of coal and convert the two remaining coal-fired units to natural gas by April 16, 2015. The plant already has three units that operate on natural gas.
At Plant Sweatt, Mississippi Power will retire two of the existing natural gas units, repower with more advanced technology or convert to an alternative non fossil-fuel source by the end of 2018.
Lastly, Mississippi Power will terminate coal operations and convert two units to natural gas by April 16, 2016 at Plant Greene County.
Mississippi Power's president and CEO stated, "With the repowering, natural gas conversion or retirement of certain units, Mississippi Power's energy mix is expected to be 60 percent powered by natural gas in 2020. This further illustrates the importance of the Kemper County energy facility, which will use locally mined, low-cost lignite, in maintaining a diverse fuel mix for our customers."
In the settlement agreement, Mississippi Power also agreed not to oppose certain aspects of the renewable net metering policy development currently being contemplated by the Mississippi Public Service Commission. Furthermore, the settlement include establishing and funding a $15 million grant for an energy efficiency and renewable energy program with the Mississippi Gulf Coast Community Foundation; complying with standards for a 100-year rainfall event when building future retention ponds associated with the Kemper County energy facility; and contributing to a conservation fund for the habitat of the Mississippi gopher frog.
