The Hidden Price Tag of South Carolina's New Gas Plant: Why Santee Cooper's Bet on Fossil Fuels is a $10 Billion Mistake
Santee Cooper and Dominion are pushing the Canadys gas plant. The real cost isn't just fuel; it's our energy future.
Key Takeaways
- •The Canadys gas plant proposal prioritizes legacy fossil fuel infrastructure over rapidly advancing, cheaper battery storage solutions.
- •Ratepayers face the high risk of absorbing 'stranded asset' costs when gas becomes economically unviable in the coming decade.
- •The move signals regulatory complacency and discourages serious investment in zero-carbon alternatives in South Carolina.
- •Expect significant ratepayer litigation and legislative battles over this plant's financing within the next 5-10 years.
Are we witnessing a historical policy blunder in real-time? While Santee Cooper and Dominion Energy parade their application for the new natural gas power plant at Canadys as a necessary step for grid reliability, the truth smells suspiciously like stranded assets and regulatory complacency. This isn't just a local utility story; it's a crucial flashpoint in the national debate over energy infrastructure investment versus climate responsibility. The push for this gas plant screams of locking in decades of high-carbon dependency just as the market pivots violently toward cheaper, cleaner alternatives.
The Unspoken Truth: Sunk Costs and Political Inertia
The primary winners here are clear: the utility shareholders and the construction firms currently enjoying lucrative, long-term contracts. The losers? Every single South Carolina ratepayer who will ultimately foot the bill for this fossil fuel behemoth. Opponents, like the Southern Environmental Law Center, rightly point to the environmental damage, but the deeper, more insidious issue is the economic one. Natural gas is a bridge fuel that is rapidly becoming a dead end. Building a massive new facility now guarantees that ratepayers will be paying off equipment that could be economically obsolete within 15 years, long before its planned retirement date. This is corporate risk externalized onto the public.
Why now? Because the regulatory environment is still sluggish enough to allow this kind of inertia to flourish. When you analyze the regulatory filings, the primary justification often hinges on 'peaking capacity'—the need for quick power during heat waves. But what they conveniently downplay is the plummeting cost of utility-scale battery storage. A modern battery farm paired with existing renewable sources offers faster response times and zero fuel price volatility compared to building a new gas turbine. This move isn't about maximizing reliability; it's about maximizing the lifespan of outdated thinking within utility boardrooms.
Why This Matters: The Stranded Asset Time Bomb
The concept of the stranded asset is the ghost haunting this entire proposal. As federal incentives for renewables increase and battery technology scales, the economic rationale for burning gas will evaporate. When that happens—and it will happen faster than utility executives predict—who absorbs the loss? Santee Cooper, a state-owned utility, means the taxpayer absorbs it. Dominion, a massive investor-owned corporation, will lobby ferociously to ensure ratepayers cover the difference. This Canadys plant is a 40-year commitment made in a 5-year technology cycle.
Furthermore, this move sends a chilling signal to clean energy developers looking at the South Carolina market: 'We are not serious about the transition.' It artificially suppresses the demand for truly forward-looking solutions like offshore wind or massive solar installations, simply because the incumbent players prefer the familiar, albeit increasingly risky, path of gas.

Where Do We Go From Here? The Inevitable Pivot
My prediction is that this plant will be approved, but it will become the most expensive, underutilized asset in the state's history within a decade. The backlash won't just come from environmental groups; it will materialize as ratepayer advocacy groups demanding accountability for the poor long-term financial planning. We will see an aggressive, almost desperate, push for federal subsidies to retrofit or prematurely retire this facility by the late 2030s. The true battleground won't be in front of the Public Service Commission now, but in the state legislature five years from now when the first major rate hike tied to this project hits.
The only viable strategy for Santee Cooper is to pivot immediately, using the permitting process delay to pivot the application toward high-efficiency combined-cycle gas turbines paired with massive battery storage—a true bridge—or, better yet, scrap it entirely and issue an RFP for firm, zero-carbon capacity. Anything less is fiscal malpractice.
Frequently Asked Questions
What is the main environmental concern regarding the Canadys gas plant proposal?
The primary environmental concern is that approving a new, large-scale natural gas plant locks South Carolina into decades of increased carbon emissions, directly contradicting broader national and global climate mitigation goals.
Who are Santee Cooper and Dominion Energy in this context?
Santee Cooper is South Carolina's state-owned electric and water utility, while Dominion Energy is a major investor-owned energy company operating in the region. Their joint application seeks approval to build and operate the new power generation facility.
What is a 'stranded asset' in the context of a new power plant?
A stranded asset is an asset (like a power plant) that suffers from unanticipated or premature write-downs, devaluations, or conversion to liabilities due to changes in regulation, technology, or market forces—in this case, the rapid decline in the cost-competitiveness of natural gas versus renewables and storage.
What role does the Southern Environmental Law Center (SELC) play?
The SELC actively opposes the construction of new fossil fuel infrastructure, advocating for cleaner energy alternatives and challenging utility proposals that they believe harm the environment and burden consumers financially.
