State Energy Overview

South Carolina has immense opportunities for clean, renewable energy. Yet on the other hand, it is currently heavily invested in conventional, risky and costly energy sources that are funneling billions of dollars out of the state each year. South Carolina, like many Southeastern states, sends more than 8 billion dollars out of state for energy resources annually to provide power. But there are local opportunities that can help shift that equation to keep more of our money in-state.

With abundant offshore wind potential, great opportunities to promote energy efficiency and innovative bioenergy research taking place, South Carolina can move decidedly in the direction of clean and renewable energy sources—but not without an engaged citizenry and proactive leaders.

Our analysis shows South Carolina has a significant amount of commercially available and sustainable biopower capacity based on various biomass resources. Utilizing any of these resources will need to be done carefully and require thorough assessments of need, resource availability and other demands, water use, biodiversity, carbon, soil quality, air quality and other economic and environmental impacts. Many projects have been proposed for the state, but the prospects for their development remain unclear, based on factors including resource availability, federal regulations and laws, financing and environmental impacts.

South Carolina has some of the best offshore wind energy potential in the entire country. A study managed by the Southern Alliance for Clean Energy suggests that enough area exists off the state’s coast to support approximately 35,500 megawatts of offshore wind development – more than enough to meet all of the state’s current energy demands. South Carolina is already one of the top wind energy manufacturing states in our region, employing more than 1,000 workers in the wind industry, and new opportunities could create thousands more jobs for South Carolinians. The state also has excellent academic institutions researching wind and dedicated teams of advocates, which sets up South Carolina to be a wind energy leader.

Investor-owned South Carolina Gas and Electric, Duke and Progress Energy, state owned Santee Cooper and the 31 electric membership corporations serve the energy needs of South Carolina which total approximately 25,000 MWs. Total solar installations only amount to about 0.01% or 3 MW. SCG&E has a 2.5 MW rooftop project with Boeing and Santee Cooper’s solar projects total less than 400 kW. Santee Cooper offers low-interest loans up to $40,000 to residential customers who install solar systems and other renewable generation up to 20 kW. Santee Cooper and SCE&G have recently announced plans to significantly increase their solar capacity, but it will still be just a small amount of their total generation.

Through its Sunsense Commercial PV Incentive Program, launched mid 2009, Progress Energy offers 15 cents per kWh to non-residential customers — largely in North Carolina, but also in South Carolina — for the electricity generated by a solar system 11-500 kW in size for a period of 20 years and limited to a program total of 5 MW annually. To participate, commercial customers must apply, be approved and execute an interconnection agreement. In January 2011, Progress made Sunsense available to residential customers, limiting the total annual subscription to 1 MW. Systems owned and operated by other providers on a customer’s property are also eligible. You can read more about solar by visiting our Learn About Solar page, here.

With the second highest percentage of nuclear power of any state in the country, South Carolinians face rising electricity prices and water-intensive energy production. Nuclear power is expensive and risky. So expensive and risky that Wall Street won’t finance new nuclear reactors. So instead, our utilities pass the costs on to the ratepayers to pay on monthly bills. In fact, some of us are already paying more on our monthly bills to finance the expensive new reactors in Jenkinsville.

Nuclear power is an extremely risky and expensive way to boil water to generate electricity. Though nuclear power plants do not release carbon dioxide like coal plants, they do release radioactive and hazardous materials, including long-lived, highly radioactive waste, that threaten our security, jeopardize our health and pollute our natural resources. The consequences of an accident or terrorist attack at a nuclear power plant could be devastating. Nuclear plants are also huge water users that deplete limited and precious water resources. Building new nuclear generation is a waste of the valuable time and money needed to address global warming and a missed opportunity to invest in real renewable solutions that can benefit our state’s economy for generations to come.

There are a total of 12 coal plants in South Carolina primarily owned by Santee Cooper and SCE&G, but Progress Energy and Duke Energy each own one coal plant (Robinson and W.S. Lee respectively) in the state. W.S. Lee is slated to retire units 1-3 by 2018 under Duke Energy’s Cliffside settlement agreement in North Carolina. South Carolina utilities spend a total of about $1.1 billion on coal each year. On the list of the top 15 states for coal health impacts, South Carolina appears at number 13. There are 283 deaths and a mortality risk of 8.4 per 100,000 adults related to pollution from coal plants in the state. In 2010, 36.2% of South Carolina’s power came from coal. Although coal has declined over the past decade from 42% in 2000, it is still a dominant part of South Carolina’s energy mix.You can read more about solar by visiting our Learn About Coal page, here.

In addition to creating air pollution, South Carolina’s power plants produce nearly 2.2 million tons of toxic coal ash every year. The ash is mostly dumped in unlined pits near waterways where it can easily pollute water used for drinking, fishing and recreation. Despite this threat, South Carolina lacks many basic safeguards to protect public health and water resources from this toxic waste. Check out this fact sheet to learn more about coal ash in South Carolina.
