LCG, March 17, 2026--Oklo Inc. (Oklo) today announced that it has signed a U.S. Department of Energy (DOE) Other Transaction Agreement (OTA) to support the design, construction, and operation of Oklo’s first reactor, the Aurora powerhouse at Idaho National Laboratory (INL) under DOE’s Reactor Pilot Program (RPP). The DOE Idaho Operations Office subsequently approved the Nuclear Safety Design Agreement (NSDA) for the fast-fission power plant, and Oklo immediately requested DOE commence review of its Preliminary Documented Safety Analysis (PDSA).

Conversion of Coal-fired Plant Near Completion

LCG, Apr. 21, 2003--The shutdown of the coal-burning part of the Noblesville power plant in Indiana in late February will be followed in June by the start-up of three new gas-fired combustion turbines, according to Cinergy Corp.

The plant was rated at 90 megawatts previously, and with the operation of the gas turbines, will have a nominal capacity of 300 megawatts. The turbines from the coal plant will be run by steam created by the new turbines. Emissions will be reduced by 94 percent, PSI Energy Inc., the Cinergy subsidiary responsible for the conversion, said.

The same firm that designed the original NOblesville plant, Sargent & Lundy, has also done the engineering work for the current installation. It is thought that the facility will produce power for about half the year, for peak demand. The increased efficiency and reduced emissions may aid PSI Energy in reaching a final agreement with the Environmental Protection Agency over emission limits to accompany capacity expansion. Hamilton County will benefit from the new turbines, as its reserve margin has been as low as 1 percent in the past few years.
