LCG, October 28, 2025--NextEra Energy and Google yesterday announced two agreements that will help meet growing electricity demand from artificial intelligence (AI) with clean, reliable, 24/7 nuclear power and strengthen the nation's nuclear leadership. First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

LCG, October 23, 2025--Google announced today a first-of-its kind agreement to support a natural gas-fired power plant with carbon capture and storage (CCS). The 400-MW Broadwing Energy power project, located in Decatur, Illinois, will capture and permanently store its carbon dioxide (CO2) emissions. By agreeing to buy most of the power it generates, Google is helping get this new, baseload power source built and connected to the regional grid that supports our data centers.

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.
