LCG, May 6, 2026--Oklo Inc. ("Oklo"), an advanced nuclear technology company, announced today that the U.S. Nuclear Regulatory Commission (NRC) has approved the Principal Design Criteria (PDC) topical report for the Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR), which is currently under construction in Idaho. The PDC topical report establishes a regulatory framework that defines the fundamental safety, reliability, and performance requirements to guide future reactor licensing and design activities, and the approved report should simplify future applications and reduce the need to re-review established material.

LCG, April 30, 2026--OG&E, the operating subsidiary of OGE Energy Corp., announced today that it will power three new data centers that Google announced in Muskogee and Stillwater, Oklahoma last year. As part of the agreement, Google will also make power generation capacity available from two solar facilities in Stephens and Muskogee Counties that are currently under construction. The data centers and associated Electric Service Agreements are expected to provide economic growth for local communities and the state, contribute to grid stability, and benefit OG&E's current customers.

Southern Files for New Nuclear Reactors at Plant Vogtle
LCG, August 16, 2006--Southern Nuclear Operating Company yesterday filed an application with the Nuclear Regulatory Commission (NRC) for an Early Site Permit (ESP) on behalf of the owners of the Alvin W. Vogtle Electric Generating Plant located near Waynesboro, Georgia. Southern had previously announced that it has selected the Westinghouse AP1000 reactor design for the two new reactors included in the project. The new electric generating capacity, which would total about 2,200 MW, is intended to meet the rapidly rising demand for power in the Southeast.
The plant owners consist of Southern Company subsidiary Georgia Power Company, Oglethorpe Power Corporation (OPC), the Municipal Electric Authority of Georgia (MEAG) and the City of Dalton. Southern Nuclear is a subsidiary of Southern Company and operates the existing two reactors at Plant Vogtle, plus two other nuclear stations in Georgia and Alabama.
The intent of filing the ESP is to enable the NRC to initiate the review of the site where the reactor units would be installed prior to the owners committing to building the new units, thereby reducing regulatory uncertainty associated with the project. Filing the ESP is not a commitment from the owners to proceed with the expansion project but preserves the option to proceed in a timely fashion to meet anticipated electric supply needs in the 2015 timeframe. In addition to NRC approval, Georgia Power will need approval from the Georgia Public Service Commission prior to proceeding with construction.
Southern Nuclear also announced yesterday that it plans in 2008 to file a Combined Construction and Operating License (COL) with the NRC for the new reactor units at Plant Vogtle. The COL would provide a single license to construct and operate the new reactors based on the previously filed ESP.
In addition to the expansion proposed at Plant Vogtle, Southern Company is pursuing the installation of four other new nuclear reactors - all using the AP1000 reactor design - at two other sites in the Southeast. In March, Southern announced that it executed an agreement with Duke Power (Duke) to jointly pursue the development of a new nuclear power plant at a site in Cherokee County, South Carolina. Duke will be the developer and plant operator, and Southern will be a co-owner of the plant located outside of Southern's traditional service territory.
At the Cherokee County site, Duke plans to proceed to prepare an application to the NRC for a COL for two Westinghouse AP1000 reactors. The COL is scheduled to be submitted to the NRC by early 2008.
In March of this year, Southern also announced another joint proposal with Tennessee Valley Authority (TVA) whereby the two companies would jointly pursue the construction of two new nuclear reactors at TVA's Bellefonte plant site near Scottsboro, Alabama.
The AP1000 reactor incorporates passive safety features that rely upon natural forces. The NRC approved the Design Certification for the AP1000 standard nuclear plant design on December 30, 2005. The AP1000 has also been selected by Progress Carolinas, SCANA and Santee Cooper as the basis for additional COL applications to construct new nuclear reactors.
