SCE&G and Santee Cooper, a state-owned utility in South Carolina, are building two 1,117-megawatt nuclear electric-generating units at V.C. Summer Nuclear Station in Fairfield County, S.C., where V.C. Summer Unit 1 has been in commercial operation for more than 30 years.

Westinghouse Electric Company is the design and construction contractor. Fluor Corporation is the construction manager.

Yes. With a project of this magnitude, there has to be some flexibility built into the process. This is a long-term project designed to ensure customers have clean, safe and reliable energy for decades to come. When the two new nuclear units go online, SCE&G’s generation mix will be about a third nuclear, a third scrubbed coal and a third natural gas. More than 60 percent of SCE&G’s generation will be non-emitting.

This is a question we have studied. That analysis still points to moving forward with new nuclear. When evaluating options for generating electricity, it’s not just about construction costs. There are many other considerations. For example, fuel costs; although natural gas prices are relatively low right now, it’s still cheaper to produce electricity using nuclear fuel. It’s extremely positive that natural gas prices are low today, but a 20-year historical review will show significant volatility in the cost of natural gas.

The natural gas industry is changing. Today, about 30 percent of our electric generation is fired by natural gas. SCE&G’s customers are enjoying the benefits of lower cost gas that shale gas fields and fracking technology has made available recently. However, this same technology is still relatively new. Wholesale natural gas prices are currently unregulated, and many question the long-term impacts of fracking. Gas producers are working on strategies to export their natural gas to overseas markets, which may place upward pressure on price. For all of these reasons, betting South Carolina’s energy future primarily on natural gas is not without risk. Gas has a role – a supporting role – in a balanced portfolio that will protect customers against price swings in any one fuel supply.

Adding nuclear power to our system will allow us to achieve a very balanced generation portfolio. Once our two new nuclear units are complete, we anticipate our generation mix will be about one-third nuclear, one-third natural gas and one-third scrubbed coal, giving us the flexibility to take advantage of whatever generation option makes economic sense for our customers at any given point in time.

Bottom line: nuclear will help reduce greenhouse gases in our state, will produce electricity more affordably than any other form of large-scale power generation currently available, and will result in a balanced energy portfolio to serve our customers. It’s simply the best solution for meeting our state’s long-term need for clean, reliable power.

Compared with all the options—including alternative sources such as wind and solar, as well as other traditional fuel sources such as coal and natural gas—nuclear was chosen after careful consideration as the best option to meet the energy needs of our customers well into the future in a manner that is safe, clean, reliable, proven, efficient, and economical. Renewable technologies such as wind and solar energy continue to improve. However, they still cannot provide the large-scale, around-the-clock generation required to meet South Carolina’s energy needs.

SCE&G promotes conservation through its EnergyWise® programs and incentives that can save customers money. Those programs include online energy-saving tips, home and business energy audits, rebates on ENERGY STAR appliances and lighting, and incentives to homebuilders.

Conservation, alternative forms of generation (like biomass and wind), and nuclear power will all play a part in meeting South Carolina's future energy needs. Each of these will be important to provide a diversified group of resources to meet the energy challenges that lie ahead. Helping consumers find energy efficient solutions is a significant part of SCANA’s balanced energy strategy.

SCE&G is continuously tracking costs and construction progress and updating the Office of Regulatory Staff (ORS) and the Public Service Commission of South Carolina (PSC) on a quarterly basis.

We estimate that our customers will see an average rate increase of about 2.5 percent per year during construction of the units. The Base Load Review Act, which is a state law enacted in 2007, effectively reduces the cost of building nuclear power plants in South Carolina by allowing the state’s regulated utilities to adjust rates annually during construction of such plants to recover related financing costs. Paying financing costs while construction is ongoing, as opposed to waiting until the project has been completed, lowers the cost of building the new units at V.C. Summer by about $1 billion, which in turn reduces the amount our customers will pay through rates for such things as the cost of capital, depreciation, property taxes and insurance associated with the project. We estimate this will save our customers at least $4 billion in electric rates over the life of the new units.

To draw an analogy, imagine you were planning to build a house and finance the purchase price with a 30-year mortgage. You could: pay any interest on the construction loan while the house is being built (like we’re doing with the new nuclear project) or pay no interest on the construction loan while the house is being built, but instead have the total amount of that interest included in your 30-year mortgage. The second option would significantly increase the amount you’d actually pay for the home because every month for 30 years you’d be paying interest on the interest associated with the construction loan.

The construction costs, as approved by the PSC, are not reflected in rates until the plants are put into service for the benefit of our customers.

We have provided information to DOE as part of the loan guarantee application process, but DOE has not provided us with specifics related to terms and conditions that might be attached to the loan guarantees. Without such information, we cannot effectively determine whether it would make sense for us and our customers to participate in the loan guarantee program. We have been consistent in stating that the loan guarantees are not essential to our ability to fund our nuclear construction project.

Nuclear plants are economic drivers. In addition to the approximately 800 workers at the operating plant, the new nuclear project will provide approximately 3,000-3,500 jobs at the peak of construction. There will be about 800 fulltime employees once construction is completed. SCE&G pays more than $20 million in property taxes for V.C. Summer Unit 1, and that amount will significantly increase when the new units are operational. SCE&G has a strong partnership with colleges and universities to meet the demands of the new nuclear workforce, and the company is cultivating the pipeline at the high school level and below. The Port of Charleston receives large components for the project and is expected to receive approximately 24,000 tons of equipment throughout construction.

SCE&G works closely with local schools to support students who are interested in Science, Technology, Engineering and Mathematics careers. For more information about construction jobs at V.C. Summer, visit and To learn about non-construction jobs, visit

The Nuclear Regulatory Commission has rigorous inspection processes for all U.S. nuclear power plants and nuclear construction projects.

SCE&G’s energy portfolio includes a diverse mix of electricity generation. This strategy relies upon increasing amounts of non-emitting nuclear and renewable electric generation, as well as existing fossil-fuel fired plants with proven emissions controls. Nuclear plants generate electricity virtually emissions-free, providing large quantities of electricity without affecting air quality or contributing to global warming.

All fuel-based electric power plants circulate large volumes of cooling water through the plant, but they actually consume only a small amount. It is projected that the existing V. C. Summer unit plus the two new units will consume less than 1.2 percent of the Broad River’s average flow.

A typical nuclear plant supplies electricity around the clock for 740,000 homes. A nuclear power plant that returns cooling water directly to the source, such as V.C. Summer’s current unit, consumes the equivalent of six to 16 gallons of water per day per household. Nuclear plants that use cooling towers, such as the two future units at V.C. Summer, would consume the equivalent of 20 to 26 gallons of water per day per household. By comparison, the average U.S. household of three people consumes about 300 gallons of water per day for indoor and outdoor uses, according to the United States Geological Survey (USGS).

The new reactor design, called the Westinghouse Advanced Pressurized Water Reactor (AP1000), builds on the industry's excellent safety record by using fewer moving parts and using cooling systems that rely on gravity instead of power supplies and motor-driven components. The AP1000 has 85 percent less cable, 80 percent less pipe, 50 percent fewer valves and 35 percent fewer pumps than today's generation of reactors.

Thorough inspections will continue over the course of the project. SCE&G expects that there will be issues, whether self-identified or identified by the regulator, which will need to be addressed along the way. This is a normal part of the nuclear licensing and construction process, it is in keeping with SCE&G’s meticulous oversight as well as the rigorous oversight by the NRC, and it ensures plants are designed and built safely.

The U.S. nuclear energy industry responded within days of the accident in Japan, inspecting plants to ensure they could withstand similar extreme natural events. In addition, V.C. Summer and the entire nuclear industry adopted a strategy to ensure that lessons learned in Japan are applied quickly and effectively at America’s reactors to make our safe plants even safer.

SCE&G has managed used nuclear fuel and other nuclear waste by-products safely and efficiently for nearly 30 years. V.C. Summer stores used fuel in its used fuel pool and has added dry storage capabilities. These robust, steel-lined, concrete containers are one of the storage methods used by nuclear stations across the U.S. As it has done safely for years with the current unit, SCE&G will store the used fuel from the additional reactor units on site. The new nuclear units will have their own fuel storage facilities — there will be no connection to the current fuel pool. Dry storage is an option for longer term storage for the new units as well. While SCE&G supports the construction of a permanent federal repository for used nuclear fuel, the company can safely store the used fuel.

In 2008, SCE&G and Santee Cooper, a state-owned utility in South Carolina, began the process of licensing and building two 1,117-megawatt nuclear electric-generating units at V.C. Summer Nuclear Station in Fairfield County, S.C., where our jointly owned V.C. Summer Unit 1 has been in commercial operation for more than 30 years. Westinghouse Electric Company served as the engineering, procurement, and construction contractor. Fluor Corporation served as the construction manager.
On July 31, 2017, SCE&G announced that it would cease construction and file a Petition for Approval of Abandonment with the Public Service Commission of South Carolina.
Our decision follows the March 2017 bankruptcy filing of Westinghouse, which eliminated the benefits of our fixed-price contract to our customers, investors, and other stakeholders. It also follows months of SCE&G and Santee Cooper each comprehensively evaluating our options to determine the most prudent path forward for the jointly-owned project. Through that evaluation, SCE&G determined that it would cost too much and take too long to complete both units. Although it appeared to SCE&G that it may have been practical to complete construction of only one unit, SCE&G decided to cease construction and file a Petition for Approval of Abandonment when Santee Cooper announced that it had decided to suspend construction of the project. A key consideration was our ability to manage future risks with the project and the potential impact to customer rates. We could not proceed with the project on our own, and therefore made the difficult but necessary determination that the most prudent course of action was for SCE&G to cease construction of both new nuclear units and file a Petition for Approval of Abandonment with the Commission. Moving forward is no longer in the best interest of our customers and other stakeholders.
At the appropriate time, we will file a request with the Public Service Commission of South Carolina to seek recovery of project abandonment costs under the Base Load Review Act. We also will be seeking approval from the Commission to use anticipated payments from the Toshiba settlement, benefits derived from tax deductions, and potentially, proceeds from the sale of any equipment on the site to mitigate future rate increases to lessen the impact on our electric customers.
We will soon file a Petition for Approval of Abandonment with the Public Service Commission of South Carolina.
Our customers have a growing need for electric power; at the appropriate time, we will inform the Public Service Commission of our plans to meet that need through a natural gas generation strategy.
