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.

State Issues Air Permit for Duke's New Coal Unit

LCG, January 30, 2008--The North Carolina Department of Environment and Natural Resources (DENR) Division of Air Quality yesterday issued the final air permit for a new, 800-MW coal-fired unit at Duke Energy's existing Cliffside Steam Station. The new air permit includes a commitment from Duke Energy Carolinas to address carbon emissions and climate change concerns. Duke plans to commence construction of the facility immediately.

The new unit at Cliffside Steam Station is scheduled to begin generating power in 2012. After the new unit commences operations, Duke will retire four older, less efficient units at Cliffside that have a capacity of about 200 MW. Furthermore, Duke agreed to retire an additional 800 MW of aging coal units in North Carolina, with the retirements scheduled as follows: 350 MW by the end of 2015, 200 MW by the end of 2016, and 250 MW by the end of 2018. Thus, after adding 800 MW of efficient new capacity with relatively low emissions, Duke will retire a total of 1,000 MW of older, less efficient coal-fired capacity between 2012 and 2018.

In March 2007, the North Carolina Utilities Commission issued a summary "Notice of Decision" to approve a Certificate of Public Convenience and Necessity (CPCN) for Duke Energy Carolinas to build only one of two proposed 800-MW, coal-fired electric generating units at the Cliffside Steam Station. Prior to the decision, the plan called for the first unit to commence operations in 2011.

The Commission's approval was conditioned upon Duke retiring four aging, units at the station when the new, 800-MW unit commences operations. The Commission noted that Duke did not demonstrate the need for both units.

Duke originally filed its CPCN with the Commission in May 2005, with the project cost estimated to be $2 billion. In October 2006, Duke filed a revised, $3 billion estimate with the Commission on a confidential basis. The cost increase was driven by new, firm price quotes for major components of the planned facility.
