As Duke seeks higher rates, will gas plant plans collide with clean energy goals?
Duke Energy is seeking significant rate increases and proposing new natural gas plants to meet soaring electricity demand, largely driven by data centers and AI, which challenges North Carolina's 2050 carbon-neutrality goals. State lawmakers and regulators are debating how to balance reliability, affordability, and climate targets amidst this unexpected growth. Senate Bill 730, which includes new guidelines for data centers and requires a study on carbon-neutrality impacts, has passed the NC House.
North Carolina's energy future is being reevaluated due to a surge in electricity demand from data centers, artificial intelligence, manufacturing, and population growth, according to Robert Cox, director of the Energy Production and Infrastructure Center at UNC Charlotte. This unexpected demand is forcing Duke Energy, regulators, and lawmakers to rethink the state's power generation strategy and how to fund it, putting pressure on North Carolina's 2050 carbon-neutrality goal.
Duke Energy is requesting an 18% rate increase over three years for residential customers and argues that new natural gas plants are necessary to ensure reliability, stating that all economically viable resources, including nuclear, renewables, storage, natural gas, and coal, are needed. Environmental groups, such as the Sierra Club, question how long-lived natural gas facilities align with the state's climate targets and if customers should bear the cost of infrastructure primarily serving large power users like data centers. However, Duke maintains its commitment to carbon neutrality by 2050, a position supported by a November 2024 North Carolina Utilities Commission order that deemed a 35-year useful life for new natural gas generation reasonable.
The debate has also reached the General Assembly, where the North Carolina House approved Senate Bill 730, known as the Ratepayer Protection Act, on June 3. This bill would impose new guidelines and restrictions on data centers and mandate a study on the financial effects of the state's carbon-neutrality requirements on electric bills. Additionally, it would prevent the retirement of certain coal and natural gas facilities until Duke Energy secures approval for a new 1,000-megawatt nuclear project. While supporters believe the legislation protects ratepayers and ensures reliability, critics argue it could impede the transition from fossil fuels.
