NuScale Power Achieves Standard Design Approval from NRC for 77 MW SMR

LCG, May 30, 2025--NuScale Power Corporation (NuScale), a leading provider of advanced small modular reactor (SMR) nuclear technology, yesterday announced that it has received design approval from the U.S. Nuclear Regulatory Commission (NRC) for its uprated 77 MW power modules. NuScale states that it remains the only SMR technology company with design approval from the NRC, and the company remains on track for deployment by 2030, with 50- and 77-MW SMR options.

EIA Presents Analysis of California's Solar and Wind Power Curtailment Challenges

LCG, May 29, 2025--The U.S. Energy Information Administration (EIA) released an analysis yesterday showing that the California Independent System Operator (CAISO), the grid operator for most of the state, is increasing its curtailment of the rapidly growing solar- and wind-powered generation facilities in order to balance electricity supply and demand, which is necessary to maintain a stable electric system.

Indiana Commission Authorizes Duke IGCC Project

LCG, November 21, 2007--Duke Energy yesterday received authorization from the Indiana Utility Regulatory Commission to proceed with the construction of a 630-MW coal-fired power plant that will use an advanced, integrated gasification combined cycle (IGCC) technology. Duke must still receive an air permit from the Indiana Department of Environmental Management. If received, construction may commence in 2008, with full operations achieved in early 2012.

The proposed project will be built at Duke's existing Edwardsport Generating Station near Vincennes, Indiana. Once the new plant is operational, the old facilities, which include coal and oil units that have a capacity of 160-MW, would be retired.

The IGCC design employed for the plant includes coal gasification. Synthetic gas created from coal is used in a gas turbine to generate electricity. The hot exhaust gas from the turbine heats water to produce steam to power a steam turbine and generate electricity a second time. The gasification process offers the potential for lower cost solutions to capture and sequester CO2, which may assist in efforts to thwart global warming.

The estimated cost of the plant is roughly $2 billion, which will be offset by over $460 million in local, state and federal tax incentives.

Duke filed an application for a "Certificate of Public Convenience and Necessity" (CPCN) with the Commission to build the plant in September 2006. Duke must justify and seek approval in a separate proceeding to recover any costs above the approved $1.985 billion.

The Commission directed Duke to proceed with its plans to develop carbon capture and storage studies and to file a proceeding with the Commission to establish that process in six months.
