Data Center Demand Derails Offshore Wind: Why Duke Energy’s 2026 Pivot Matters

Offshore Wind Projects Face New Headwinds from Data Center Growth

Surging electricity demand from the rapid expansion of data centers, combined with prohibitive project costs, has emerged as a primary risk for U.S. offshore wind development, forcing utilities like Duke Energy to shelve previously planned projects in favor of firm power generation. This pivot marks a significant reversal from the industry’s trajectory in the early 2020 s, where decarbonization goals were the primary driver of utility resource planning.

• Between 2021 and 2024, Duke Energy was methodically advancing its offshore wind strategy, acquiring the $155 million Carolina Long Bay lease in May 2022 and formally targeting the development of up to 2.4 GW of offshore wind capacity by 2035 as a cornerstone of its regulated decarbonization plan.
• This strategy was upended throughout 2025, culminating in the October 2025 Carolinas Resource Plan filing that shelved near-term offshore wind ambitions, pushing any potential development into the 2040 s. The company cited non-competitiveness and prohibitive costs, with internal estimates for 8 GW of offshore wind in North Carolina ranging from $55.7 billion to $71.5 billion.
• The primary catalyst for this reversal was an unforeseen surge in projected electricity demand, largely fueled by the expansion of data centers from customers like Microsoft. This new load growth forced Duke Energy to prioritize immediately dispatchable and cost-effective generation over the long-term, capital-intensive development cycle of offshore wind.

Capital Reallocation: Duke Energy’s $103 B Shift from Wind to Gas and Nuclear

Duke Energy’s strategic pivot in 2025 triggered a massive reallocation of its capital expenditure, shifting billions away from its nascent offshore wind program and toward a combination of natural gas, battery storage, and advanced nuclear technologies to meet urgent grid demands. This financial redirection is formalized in the utility’s updated five-year capital plan, which was increased to $103 billion, the largest among U.S. regulated utilities.

• The most significant cancellation was the shelving of the planned 2, 400 MW offshore wind procurement by 2035, which effectively froze a multi-billion-dollar investment pipeline despite the company’s existing $155 million investment in the Carolina Long Bay federal lease.
• Capital was immediately redirected toward firm power, highlighted by an April 2025 arrangement with GE Vernova to procure up to 11 new natural gas turbines. This move is supported by new midstream infrastructure projects, such as Enbridge’s T 15 pipeline expansion, to ensure fuel supply.
• The new plan also accelerates investment in grid flexibility and future carbon-free power, increasing the 2035 battery storage target by nearly 1, 000 MW to 6, 540 MW and allocating funds to advance the development of GE-Hitachi’s BWRX-300 Small Modular Reactor (SMR) technology.

Partnership Ecosystems Pivot with Duke Energy’s Offshore Wind Strategy

Duke Energy’s abrupt strategic re-evaluation in 2025 triggered a corresponding realignment of its partnership ecosystem, deprioritizing its regional offshore wind co-development relationship with Total Energies and elevating collaborations with firm power technology providers like GE Vernova and GE-Hitachi.

• The dynamic established in May 2022, where Duke Energy and Total Energies became de facto regional partners after winning adjacent leases in the Carolina Long Bay auction, was effectively put on hold. What was once a promising collaboration for a major East Coast wind hub is now in question.
• In contrast, new alliances focused on firm power generation became central to Duke Energy’s strategy in 2025. An April 2025 arrangement with GE Vernova for natural gas turbines became a cornerstone for meeting near-term demand.
• Simultaneously, a January 2025 investment agreement with GE-Hitachi Nuclear Energy to advance the BWRX-300 SMR design signals a long-term strategic bet on advanced nuclear, positioning it as a key carbon-free technology to fill the gap left by offshore wind.

North Carolina’s Offshore Wind Leadership Stalls Amidst Grid Pressures

North Carolina’s ambition to become a leader in the U.S. offshore wind market has been significantly delayed after its primary utility, Duke Energy, prioritized immediate grid stability in the Carolinas over the long-term development of renewable energy in the Atlantic. This move shifts the regional competitive landscape, ceding a first-mover advantage to neighboring states.

• During the 2021-2024 period, North Carolina was positioned as a key future hub for East Coast offshore wind. The federal government’s successful Carolina Long Bay lease auction in 2022, won by Duke Energy and Total Energies, created significant commercial and political momentum for the state.
• The 2025 pivot reverses this trajectory. Duke Energy’s decision to delay offshore wind development until the 2040 s at the earliest puts North Carolina at a distinct disadvantage to Virginia, where competitor Dominion Energy’s 2.6 GW Coastal Virginia Offshore Wind project remains on track for completion by late 2026.
• While the geographical asset of the lease area remains, near-term development activity in the Carolinas has shifted inland. Capital is now flowing toward new natural gas plants and potential SMR sites like Belews Creek, reflecting a strategic focus on leveraging existing onshore infrastructure to meet urgent demand.

Offshore Wind’s LCOE Deemed Immature for 2026’s Urgent Power Needs

Duke Energy’s 2025 decision demonstrates that while offshore wind turbine technology is mature for deployment, its current levelized cost of energy (LCOE) and long development timelines are misaligned with the immediate, large-scale, and cost-sensitive power demands driven by industrial expansion and data centers.

• From 2021 to 2024, the primary challenge was seen as de-risking a technologically proven solution, fixed-bottom turbines, through environmental studies and regulatory engagement. The focus of efforts like the WOW project with Duke University was on environmental and permitting risk, not fundamental technology or cost questions.
• In 2025, the central issue became economic viability, not technical feasibility. High projected costs and an LCOE that was non-competitive against alternatives like new natural gas plants, estimated at around $50/MWh, made the technology untenable for meeting immediate needs from a customer cost perspective.
• The utility’s pivot toward mature technologies (advanced gas turbines) and emerging but potentially more cost-controllable firm power sources (SMRs) shows a clear preference for assets that can meet both baseload and dispatchable needs more predictably and affordably in the near-to-mid term.

SWOT Analysis: Duke Energy’s Strategic Shift on Offshore Wind

The strategic analysis reveals a pivot from leveraging federal support for long-term renewable growth to addressing the immediate threat of overwhelming load growth with proven, cost-effective technologies.

2026 Outlook: Watching for a Tipping Point in Gas vs. Renewables Costs

Looking ahead to 2026, the critical question is whether the economic calculus that drove Duke Energy’s pivot away from offshore wind will hold, or if falling renewable costs, rising gas price volatility, or new policy measures will force another strategic re-evaluation.

• If this happens: Should natural gas prices experience sustained volatility or a significant price increase, or if a federal or state carbon price is introduced, the operational expenditures of Duke’s new gas-heavy strategy will rise, making shelved renewable projects appear more economically attractive in retrospect.
• Watch this: The final “all-in” cost and operational performance of Dominion Energy’s 2.6 GW Coastal Virginia Offshore Wind project, expected to be completed in late 2026, will provide a crucial real-world benchmark for offshore wind LCOE in the Southeast, either validating or challenging Duke’s cost assumptions.
• These could be happening: Monitor any commercial activity related to Duke’s $155 million Carolina Long Bay lease. A sale to another developer would signal a definitive long-term exit, while holding the asset preserves future optionality. Also, track progress on early site permits for SMRs, as this is Duke’s primary hedge for long-term, carbon-free firm power.

Frequently Asked Questions

Why did Duke Energy abandon its near-term offshore wind plans?

Duke Energy shelved its offshore wind plans primarily due to an unexpected surge in electricity demand, largely from data centers. This forced the utility to prioritize more cost-effective and immediately available ‘firm’ power sources like natural gas over the long-term, high-cost development cycle of offshore wind, which was deemed non-competitive with cost estimates ranging from $55.7 billion to $71.5 billion for 8 GW.

What is Duke Energy investing in instead of offshore wind?

Duke Energy is reallocating its capital towards a combination of natural gas, battery storage, and advanced nuclear power. This includes procuring up to 11 new natural gas turbines from GE Vernova, increasing its 2035 battery storage target to 6,540 MW, and investing in the development of GE-Hitachi’s BWRX-300 Small Modular Reactor (SMR) technology.

What will happen to the $155 million Carolina Long Bay lease that Duke Energy purchased?

Following the decision to shelve its offshore wind projects, the $155 million investment in the Carolina Long Bay federal lease is now stalled. While development is halted, Duke Energy still holds the asset, preserving the option for future development. The article suggests monitoring whether Duke sells the lease, which would signal a long-term exit, or continues to hold it.

How does this decision affect North Carolina’s position in the offshore wind industry?

Duke Energy’s pivot significantly delays North Carolina’s ambition to become a leader in the U.S. offshore wind market. By pushing its own projects into the 2040s, it effectively cedes a first-mover advantage to neighboring states like Virginia, where Dominion Energy’s 2.6 GW offshore wind project is still on track for completion in 2026.

Are all offshore wind projects on the East Coast being cancelled?

No. While Duke Energy has paused its projects in the Carolinas, the article notes that other projects are moving forward. A key example is competitor Dominion Energy’s 2.6 GW Coastal Virginia Offshore Wind project, which remains on track for completion by late 2026 and will serve as a crucial real-world cost benchmark for the industry.
