The long-awaited completion of Unit 3 at Plant Vogtle, a nuclear power plant located southeast of Augusta, marks a significant milestone as the first American atomic reactor to be constructed from the ground up in decades. Despite its successful operation and reliable electricity generation, there are concerns about the project’s substantial cost, which amounted to $17 billion over budget and was delayed by seven years.
Georgia Power Co. announced Unit 3’s commercial operation, revealing that it can produce 1,100 megawatts of electricity to power approximately 500,000 homes and businesses. The electricity generated benefits the 2.7 million Southern Co. subsidiary Georgia Power customers and is being distributed to other utilities in Georgia, Florida, and Alabama.
While the completion of the nuclear reactor is a remarkable achievement in pursuing a carbon-free future, the substantial cost overruns and delays could discourage other utilities from considering atomic power as a viable option to reduce carbon emissions. Balancing the benefits of nuclear power, a low-carbon energy source, with its considerable financial challenges remains a concern for the industry.
“This hadn’t been done in this country from start to finish in some 30-plus years,” remarked Chris Womack, CEO of Southern Co. based in Atlanta, during a recent telephone interview. “So to do this, to get this done, to get this done right, is a wonderful accomplishment for our company, for the state and for the customers here in Georgia.”
Construction Delays and Cost Overruns: A Troubled Nuclear Project
At the nuclear site, a fourth reactor is almost finished, joining two older reactors that have been providing electricity for many years. According to the Nuclear Regulatory Commission, they anticipate loading radioactive fuel into Unit 4 by the end of September. This move is part of the preparation for Unit 4 to begin commercial operation, which is scheduled for March.
The original budget for the third and fourth reactors was $14 billion, but their current projected cost has increased to $31 billion for the owners. This amount doesn’t even include the $3.7 billion the contractor, Westinghouse, paid to the owners as compensation for walking away from the project. In total, the spending is now approaching $35 billion.
Initially, the third reactor was supposed to start generating power in 2016, but construction began in 2009.
Potential Implications and Future Outlook for Nuclear Reactor in Addressing Climate Change
The Vogtle nuclear power plant is significant because government officials and some utilities see nuclear power as a crucial solution for addressing climate change. Nuclear power provides a way to generate electricity without relying on natural gas, coal, or oil. However, the current focus in the U.S. is more on smaller nuclear reactors. Advocates hope these smaller reactors can be built with better cost control and schedule adherence, unlike the challenges Vogtle faces. Southern Co., the company behind Vogtle, has no plans to add more reactors to its existing fleet.
The utility company is expected to face opposition from longstanding opponents of the nuclear plant. Many critics argue that solar and wind power options would be more cost-effective. They express concern that allowing Georgia Power to pass on the costs of mistakes made during the Vogtle project will unfairly increase the utility’s profits.
In the coming decision, the commissioners will determine who bears the remaining costs of Vogtle, including the fourth reactor. Customers will be responsible for paying their share of the expenses deemed reasonable by the commissioners. On the other hand, any spending considered wasteful will be covered by the company and its shareholders.
According to Georgia Power CEO Kim Greene, the amount customers will be asked to pay has not yet been decided.
