LCG, May 19, 2026--Avangrid, Inc., a member of the Iberdrola Group, today announced the signing of a long-term Power Purchase Agreement (PPA) with Puget Sound Energy (PSE) for the 199.5-MW Big Horn I wind project in Klickitat County, Washington. This agreement represents the fourth PPA executed by the two companies for projects in the Pacific Northwest.

LCG, May 18, 2026--The U.S. Secretary of Energy today issued an emergency order to address critical grid reliability issues in the Midwest anticipated this summer. The order is in effect beginning on May 19, 2026, through August 16, 2026. The emergency order directs the Midcontinent Independent System Operator (MISO), in coordination with Consumers Energy, to ensure that the J.H. Campbell coal-fired power plant (Campbell Plant) in West Olive, Michigan shall take all steps necessary to remain available to operate and to minimize costs for the region.

NRC Accepts Construction Permit Application for Dow's Advanced X-energy SMR Project in Texas
LCG, May 14, 2025--The U.S. Nuclear Regulatory Commission (NRC) accepted Dow's construction permit application to build X-energy Reactor Company, LLC's ("X-energy") first small modular reactor (SMR) plant to power a chemical facility in Seadrift, Texas. Dow's wholly-owned subsidiary, Long Mott Energy LLC, is developing the project to provide Dow's UCC1 Seadrift Operations manufacturing site with safe, reliable, and clean power and industrial steam to replace existing energy and steam assets that are approaching end-of-life. The project is part of a demonstration project supported by the U.S. Department of Energy (DOE) and, if approved, would be the first advanced nuclear facility at an industrial site in the United States.
The relatively rapid acceptance by the NRC of the construction permit application is an example of streamlining the licensing process, as Dow and X-energy only recently announced the submission of their application to the NRC on March 31. The NRC stated that the application applied new technology-inclusive guidance issued by the NRC to streamline the review process for non-light-water reactor applicants. The new guidance leverages the industry-led Technology-Inclusive Content of Application Project (TICAP) project to support a more risk-informed review of the safety analysis report (SAR) used to support an advanced reactor application. The TICAP effort is a direct result of a larger licensing modernization project supported by DOE in collaboration with industry and NRC.
The Long Mott Generating Station project will include four Xe-100 SMRs, which are high-temperature, gas-cooled SMRs powered by specialized TRISO particle fuel (TRISO stands for TRi-structural ISOtropic). A single SMR can produce 80 MW of electric output or 200 MW of process heat and is designed to operate for 60 years.
Since 2018, X-energy, and subsequently Dow, have worked with the NRC to demonstrate the safety profile of the Xe-100 advanced SMR through its advanced fuel design and passive safety features. (As stated by the DOE, "TRISO particles cannot melt in a commercial high-temperature reactor and can withstand extreme temperatures that are well beyond the threshold of current nuclear fuels.") This work has resulted in a comprehensive application submittal, which X-energy states exceeds NRC regulations for the protection of public health and safety, as well as the environment, with substantial safety features.
X-energy was selected by the DOE in 2020 to develop, license, and build an operational Xe-100 advanced SMR and TRISO-X fuel fabrication facility. Since that award, X-energy has completed the engineering and preliminary design of the nuclear reactor and has begun development and licensing of a fuel fabrication facility in Oak Ridge, Tennessee. Furthermore, X-energy has secured approximately $1.1 billion in private capital to commercialize its technology.
Dow anticipates that construction of the plant could begin within the next five years. Approval of the construction permit may take up to 30 months. Once the permit is received and upon Dow confirming the ability to deliver the project while achieving its financial return goals, construction could begin. Dow expects the cost of energy (net of all subsidies) to be competitive with other alternatives for firm, clean energy. X-energy's advanced SMR may be the first, grid-scale advanced nuclear reactor developed to serve an industrial site in North America.
