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.

Cost Estimate Increases for Duke's IGCC Project
LCG, November 25, 2009--Duke Energy Indiana (Duke) yesterday announced that design modifications and growth in the scope of its coal-fired, Edwardsport integrated gasification combined cycle (IGCC) project are expected to add approximately $150 million to the prior cost estimate of $2.35 billion.
Duke submitted the new cost estimate with the Indiana Utility Regulatory Commission (IURC) as part of its semi-annual update and is requesting the IURC to schedule a separate proceeding by next March, following additional engineering efforts and a revised cost estimate, together with associated rate impacts. The IRUC must approve any cost increase for the project.
Construction on the project commenced last year at Duke's existing Edwardsport Generating Station near Vincennes, Indiana and is scheduled for completion in 2012. Once the new, 630-MW power plant is operational, the old facilities, which include coal and oil units that have a capacity of 160-MW, will be retired.
With the IGCC design, 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. Duke has a request pending before state utility regulators to study permanent underground carbon storage in geologic formations of a portion of the plant's carbon dioxide emissions.
Duke filed an application for a "Certificate of Public Convenience and Necessity" (CPCN) with the IURC to build the plant in September 2006. In November 2007, the IURC directed Duke to develop carbon capture and storage (CCS) studies for the project, and Duke filed its plans in May 2008, together with the $365 million cost increase request. In January 2009, Duke received favorable rulings from the IURC that approved the revised cost estimate of $2.35 billion.
The project is expected to receive more than $460 million in local, state and federal tax incentives that will reduce the cost impact on Duke's customers.
