Duke Energy's South Carolina Gas Plant: A Strategic Pivot for Growth and Grid Resilience

Duke Energy's proposed 1.4-gigawatt (GW) natural gas-fired power plant in Anderson County, South Carolina, represents a critical strategic move to address surging regional energy demand while positioning the utility as a leader in forward-thinking grid modernization. By leveraging existing infrastructure, advanced turbine technology, and state policy tailwinds, the project underscores Duke's ability to balance affordability, reliability, and environmental stewardship in an era of rapid industrial and population growth. For investors, this project is a bellwether for utilities navigating the dual challenges of decarbonization and infrastructure renewal.

The Strategic Case for the Anderson County Plant

The plant's location on a 200-acre site near Highway 81 South and True Temper Road is no accident. Duke has deliberately chosen a site with existing transmission infrastructure, minimizing the need for costly new grid investments. This strategic decision slashes upfront capital expenditures and accelerates timelines—a key advantage in a market where regulatory hurdles and supply chain constraints often delay projects. The plant's design also reduces water usage by 50% compared to conventional gas plants, easing environmental concerns and local permitting risks.

The project's GE Vernova partnership is equally pivotal. The turbines supplied by GE's Greenville, South Carolina, facility are not just advanced combustion engines but hydrogen-ready platforms. This dual capability allows Duke to pivot toward cleaner fuels as hydrogen infrastructure matures, future-proofing the plant's value over its 30+ year lifespan. GE's $160 million expansion of its South Carolina factory to boost turbine production further aligns with Duke's supply chain strategy, reducing dependency on imported equipment.

State Policy as a Tailwind

South Carolina's Energy Security Act of 2025 has been a game-changer. By expediting permitting for projects like the Anderson plant and prioritizing gas-fired generation, the law addresses a critical gap in the state's energy mix. With demand growing at 4–5% annually due to data centers, advanced manufacturing, and population expansion, Duke's plant will provide the flexible, reliable capacity needed to prevent outages and keep rates stable. The law's emphasis on hydrogen-readiness also aligns with Duke's long-term decarbonization goals, creating a regulatory moat for the utility.

The Investment Thesis: Grid Modernization as a Growth Engine

For investors, the Anderson County plant is a microcosm of Duke's broader $83 billion five-year investment plan—a strategy that combines grid resilience, fuel flexibility, and regulatory alignment. Here's why this matters:

1. Lower Risk, Higher Returns:
2. The plant's reliance on existing infrastructure and GE's local supply chain reduces execution risks.

3. Regulatory support under the Energy Security Act expedites approvals, mitigating delays.
   

4. Hydrogen-Readiness as a Competitive Edge:

5. The 7HA turbines' ability to burn up to 30% hydrogen now and 100% in the future positions Duke to capitalize on emerging green hydrogen markets.

6. This flexibility reduces stranded asset risk as decarbonization policies tighten.

7. Economic Multiplier Effects:

8. The project will create 600 construction jobs and 30 permanent roles, bolstering local economies.
9. GE's turbine manufacturing in South Carolina creates a symbiotic relationship, benefiting both companies' bottom lines.

Risks and Considerations

While the project's fundamentals are robust, investors should monitor three risks:
- Supply Chain Volatility: GE's turbine production timelines must stay on track to avoid delays.
- Regulatory Hurdles: Though the Energy Security Act streamlines permitting, public opposition or environmental challenges could arise.
- Gas Price Volatility: Natural gas remains a price-sensitive commodity; prolonged spikes could strain affordability.

Investment Recommendation

Duke Energy's Anderson County plant is a core holding for investors seeking stable, regulated utility growth. The project's alignment with state policy, its use of advanced technology, and its focus on future-proofing through hydrogen-readiness make it a model for grid modernization. With Duke's dividend yield of 3.2% (as of June 2025) and a track record of consistent earnings growth, the utility is well-positioned to deliver steady returns.

Buy and Hold: Investors should view the Anderson County plant as a catalyst for Duke's long-term value creation. As South Carolina's energy demand grows and hydrogen infrastructure scales, this project will underpin Duke's earnings resilience while shielding it from obsolescence.

In a sector where adaptability is key, Duke's strategic bet on gas with a hydrogen future is a masterstroke—one that investors should welcome as a pillar of their utility portfolios.
