Why Data Centers Are Leaving South Carolina

South Carolina has long positioned itself as a business-friendly state — low taxes, available land, and a growing port economy. But when utility officials stood before state senators and acknowledged that fewer data center firms are even bothering to put SC on their shortlist, it signaled something more serious than a slow quarter. It signaled a structural problem.

The data center industry doesn't wait around. These developers are making billion-dollar site selection decisions on 18-to-24-month timelines, and if a state can't check the right boxes fast enough, they move on. Right now, South Carolina is watching that happen in real time.

The Numbers Behind the Retreat

Data center development has been one of the hottest infrastructure investment categories in North America over the past five years. Hyperscalers — Amazon, Microsoft, Google, Meta — along with a wave of colocation and wholesale providers, have been absorbing land and power capacity at a rate that would have seemed implausible a decade ago. Northern Virginia alone absorbs gigawatts of new capacity annually. The Carolinas, Georgia, and Texas have all competed aggressively for overflow demand.

South Carolina had geographic advantages that should have made it a natural destination: proximity to the Southeast corridor, coastal connectivity, and relatively affordable land. Yet utility officials are now telling legislators that fewer developers are running the numbers on SC locations — which means the state isn't losing deals at the finish line; it's being eliminated from consideration entirely.

That's a meaningfully worse problem. Losing a deal late in the process suggests a specific weakness. Being screened out early suggests systemic ones.

Utility Rates Are the First Filter

When a data center site selector opens a spreadsheet to evaluate a new market, power cost is usually column one. A hyperscale data center consuming 100 MW of power — a modest facility by today's standards — will spend tens of millions of dollars annually on electricity. At that scale, a difference of even half a cent per kilowatt-hour translates to millions of dollars per year, compounded over a 20-to-30-year asset life.

South Carolina's utility rate environment has not been competitive enough to clear that first filter for a growing number of developers. Virginia, Texas, Georgia, and increasingly Ohio and Indiana have structured industrial power rates and dedicated large-load programs that signal to developers: *we want your load, and we've built a framework to support it.*

The absence of a purpose-built large-load tariff isn't just a pricing issue — it's a signal about whether a state's utility infrastructure is ready to partner at scale. Developers aren't just buying electrons; they're buying a relationship with a utility that understands their operational requirements: redundant feeds, fast interconnection timelines, predictable rate escalation, and the ability to scale capacity as their campuses grow.

When utilities haven't built that framework, developers assume the education process will be slow and the deal timeline will stretch. They go somewhere else.

Infrastructure Readiness and the Site Selection Clock

Beyond rates, the physical infrastructure question is equally decisive. Data centers require substantial transmission capacity at the point of interconnection, and in many parts of South Carolina, the grid wasn't built with gigawatt-scale industrial loads in mind. Upgrading that infrastructure takes time — often years — and developers are not going to anchor their expansion plans to a speculative grid upgrade timeline.

Fiber density matters too. While South Carolina has made investments in broadband infrastructure, the density of long-haul fiber routes that data center operators depend on for low-latency connectivity to major population centers is thinner than in competing markets. A data center in Northern Virginia or Atlanta can connect to dozens of carrier routes. That redundancy is non-negotiable for enterprise and cloud customers.

The regulatory permitting environment adds another layer. States that have streamlined environmental review and permitting for large-scale industrial facilities — particularly those with significant water consumption from cooling systems — have a meaningful advantage. Every month added to a permitting timeline is a month of delayed revenue for a developer, and in a capital-intensive business with high borrowing costs, that delay has a real dollar figure attached to it.

What Competing States Are Doing Right

Georgia's success is instructive. Georgia Power has structured specific programs for large commercial and industrial loads, and the state has been aggressive about pre-entitling sites and marketing them to developers before they even start their search. When a site selector calls Georgia, there's often a ready answer: here's a site, here's the available power capacity, here's the timeline. That clarity is worth enormous amounts of deal momentum.

Texas leans on deregulated market structure and sheer scale of available land and transmission. Ohio and Indiana have recruited aggressively using a combination of tax abatements, utility cooperation, and state-level economic development resources. North Carolina, South Carolina's neighbor, has attracted significant data center investment in part because Duke Energy built a dedicated framework for engaging with hyperscale developers.

South Carolina hasn't been absent from this competition — there have been projects, and the state does have some facilities operating. But "some facilities operating" is not the same as being a go-to destination, and the gap between those two positions is widening.

The Regulatory and Incentive Gap

South Carolina does offer data center sales tax exemptions on equipment, which is a baseline incentive most competing states also provide. The problem is that a sales tax exemption has become table stakes, not a differentiator. Developers expect it; it doesn't move the needle.

What moves the needle is a combination of factors working together: a utility that has a dedicated large-load program, a state economic development agency that can shepherd projects through permitting, access to renewable energy for developers with sustainability commitments, and some form of property tax incentive structure that makes the long-term cost basis competitive.

South Carolina hasn't assembled that full package, and in a market where developers have abundant choices, "most of the ingredients" isn't good enough. Virginia didn't become the world's largest data center market by accident. It built a coordinated ecosystem — utilities, regulators, developers, and local governments — and maintained it over decades.

What Could Actually Change the Trajectory

The path forward isn't complicated, but it requires political will and utility cooperation that hasn't materialized yet.

The most impactful near-term move would be for South Carolina's major utilities to develop and file formal large-load interconnection programs with the Public Service Commission. Not a vague commitment to work with large customers, but a structured tariff with defined timelines, pricing tiers, and reliability commitments. That single step would change how developers perceive the market.

Second, the state should identify and pre-entitle two or three marquee sites with confirmed power availability. Shovel-ready data center sites with known utility capacity are the closest thing to a guaranteed deal in this industry. Developers will trade some cost disadvantage for certainty because certainty has enormous financial value.

Renewable energy access is increasingly non-negotiable for the largest buyers. Microsoft, Google, and Amazon all have aggressive sustainability targets and require markets where they can either source renewable energy directly or participate in utility green tariff programs. Expanding South Carolina's renewable procurement options — whether through utility green tariffs or direct access — would remove a disqualifier for a significant segment of the market.

What Happens If Nothing Changes

The economic stakes are substantial enough to take seriously. A single 100 MW hyperscale data center campus represents hundreds of millions of dollars in construction activity, significant ongoing equipment procurement, and years of high-wage technical employment. Larger campuses — the 500 MW to 1 GW campus developments that have become common — represent economic impacts that dwarf most other industrial recruitment wins.

More importantly, data centers create durable demand for local power, which spreads transmission and generation costs across a larger base, potentially benefiting all ratepayers. They consume relatively little water compared to traditional manufacturing. They generate property tax revenue without proportional demands on schools or public services.

South Carolina is not out of the game. The fundamentals — land availability, geographic positioning, and a growing technical workforce — haven't disappeared. But the window to build a competitive position is narrowing as other states continue to invest in the infrastructure and institutional relationships that developers are looking for.

The utility officials who testified before the Senate weren't delivering a postmortem; they were delivering a warning. Whether South Carolina acts on it will determine whether the state captures a meaningful share of one of the largest infrastructure investment waves of the next decade — or watches it flow to Georgia, North Carolina, and beyond.
