Grid Under Siege: How Data Center Demand Redefined Dominion Energy’s Strategy in 2026

Data Center Power Demand Shifts from Growth to Grid-Breaking Scale

The scale of electricity demand from data centers in Virginia has transformed from a significant growth driver into a systemic challenge, forcing Dominion Energy to fundamentally restructure its investment, generation, and regulatory strategies to prevent grid instability. This shift is defined by a rapid escalation in both the size and volume of power requests, moving beyond manageable annual growth to a level that threatens to overwhelm existing infrastructure and planning cycles.

• Between 2021 and 2024, data center demand was a rapidly growing but relatively predictable part of Dominion’s load, rising from 21% to 24% of total Virginia electricity sales. During this period, the utility managed this expansion by connecting dozens of new facilities, such as the 15 data centers totaling 933 MW of new capacity that were brought online in 2023.
• Starting in 2025, the demand profile changed dramatically, with individual data center campus requests escalating from a typical 30 MW to between 300 MW and “several gigawatts.” This explosive growth is reflected in Dominion’s pipeline of contracted capacity, which soared from approximately 40 GW in early 2025 to 47.1 GW by October 2025, pushing connection wait times out by several years.
• This escalation moved the primary strategic challenge from accommodating growth to ensuring basic grid reliability. In response, Dominion accelerated plans for massive infrastructure projects, including new gas-fired generation, and began pursuing paradigm-shifting solutions like Small Modular Reactors (SMRs) and novel rate structures specifically for large energy users.

Dominion’s $50.1 B Capital Plan: A Direct Response to Data Center Power Demand

Dominion Energy‘s capital investment strategy has been completely reshaped by data center power requirements, triggering a historic increase in its long-term spending plans to fund the necessary generation and transmission infrastructure. The utility’s financial planning now directly reflects the urgent need to build a larger, more resilient grid capable of supporting hyperscale electricity consumption, with a clear line drawn between data center growth and massive new capital outlays.

• In February 2025, Dominion announced a 16% increase in its five-year (2025-2029) capital expenditure plan to $50.1 billion, up from a previous forecast of $43.2 billion. The company explicitly cited the need to meet accelerating power demand from data centers as the primary driver for this substantial increase.
• Within this updated plan, a $17 billion portion was specifically identified to support data center growth and the broader clean energy transition. This allocation confirms that the majority of new capital is being directed toward accommodating the power needs of the digital economy.
• This strategic investment is materializing as large-scale, targeted projects. Key examples include a planned $1 billion super high-voltage transmission line to serve data center hubs and a proposal for a new 1, 000 MW natural gas plant in Chesterfield County, both aimed at meeting near-term demand.
• The utility’s nearly $10 billion investment in the 2.6 GW Coastal Virginia Offshore Wind (CVOW) project is also intrinsically linked to this strategy. Dominion has framed the project as a critical source of large-scale, carbon-free power required to serve its data center customers.

Strategic Alliances: How Dominion is Co-opting Hyperscalers to Build the Future Grid

Dominion Energy has shifted from a traditional utility-customer dynamic to forging deep, strategic alliances with hyperscalers and technology firms to jointly develop and finance next-generation energy solutions. This collaborative model, born out of the necessity to meet unprecedented power demand, treats data center operators not just as consumers but as co-investment partners in building the future grid.

• Before 2025, partnerships were largely transactional, centered on Electric Service Agreements and coordinating grid connections. While collaborative, these arrangements did not typically involve joint development of new generation technologies.
• The pivotal change occurred in late 2024 and 2025 with Amazon. What began as a Memorandum of Understanding (MOU) in October 2024 evolved into a formal collaboration by June 2025 to jointly develop up to 5 GW of nuclear energy, including a $500 million venture for a 300 MW SMR. This represents a paradigm shift toward co-investment in new, firm, carbon-free power generation.
• This trend extends to technology and regional development. In July 2025, Dominion partnered with the startup FLUIX AI through its Hyperscaled Program to use artificial intelligence to better predict and manage data center load, improving grid stability.
• Further, a October 2025 partnership with Appalachian Power and Invest SWVA aims to advance energy storage technology to attract data centers to new regions within Virginia, demonstrating a strategy to use alliances to manage geographic load concentration.

Virginia’s Data Center Alley: The Epicenter of Global Power Demand and Grid Strain

Virginia, particularly the northern part of the state, has solidified its role as the dominant global market for data centers, but this extreme geographic concentration has created an intense, localized strain on Dominion Energy’s grid. This has forced the utility and regional planners to seek solutions that extend beyond “Data Center Alley, ” including developing new infrastructure in other parts of the state and engaging in multi-state transmission planning.

• Between 2021 and 2024, Northern Virginia was the clear focal point of data center development, driving the majority of Dominion’s load growth and cementing its reputation as the world’s largest data center market. Infrastructure challenges, while emerging, were largely contained to this region.
• From 2025 onwards, the geographic strategy began to diversify as a direct result of grid constraints. Projects like the proposed 1 GW gas plant and new transmission lines to serve a 900 MW campus in Chesterfield County show that significant new load is being sited outside the traditional core.
• The strain is now forcing a deliberate geographic expansion strategy. The October 2025 partnership with Appalachian Power and Invest SWVA is designed to build out energy infrastructure in Southwest Virginia, creating new viable locations for data center development away from the congested northern region.
• The problem’s scale has transcended state lines. Dominion’s collaboration with other regional utilities like AEP on transmission proposals to the PJM Interconnection in late 2024 confirms that serving Virginia’s data centers is now a regional grid planning challenge.

From Renewables to Reactors: Data Center Demand Accelerates Next-Gen Power Tech

The unprecedented 24/7 power demand from data centers has forced Dominion Energy to accelerate its technology adoption timeline, pushing emerging solutions like Small Modular Reactors from long-term concepts to near-term commercial priorities. This shift reflects a recognition that conventional and intermittent renewable resources alone are insufficient to power the AI-driven digital economy, necessitating a pivot to firm, carbon-free generation and innovative grid management technologies.

• In the 2021-2024 period, Dominion’s technology strategy to serve data centers focused on deploying commercially mature technologies. This included connecting facilities to the existing grid and planning for large-scale renewables like the Coastal Virginia Offshore Wind project.
• The period from 2025 onward is marked by a clear pivot toward next-generation technology. The formal collaboration with Amazon to develop a 300 MW SMR represents a strategic commitment to advanced nuclear as a viable, scalable, and carbon-free baseload power source specifically for hyperscale customers.
• Innovation is also occurring in grid management and finance. In November 2025, Dominion secured approval for a new rate class (GS-5), a financial product designed to make data center developers directly fund the infrastructure they require. In early 2026, it filed a new large-load connection queue plan, a procedural technology to manage the overwhelming demand more efficiently.
• The utility is also investing in grid digitization and automation. Its work to automate its AVEVA PI System, which manages over 5 million data tags, and its collaboration with FLUIX AI are critical for managing the complex, dynamic loads from data centers in real time.

SWOT Analysis: Dominion’s Pivot in the Data Center Power Race

Dominion Energy’s guaranteed, massive load growth from data centers serves as a powerful strategic strength, but this same growth exposes critical weaknesses in grid capacity and creates significant threats from regulatory and ratepayer pushback. This dynamic has forced the utility to pursue unique opportunities, such as first-of-a-kind partnerships and new technologies, to transform these challenges into a sustainable business model.

• If this happens: The new GS-5 rate class, approved in November 2025, successfully shifts the financial burden of new infrastructure to data center developers. Watch this: Monitor Dominion’s revenue from this rate class and its impact on the funding pace for its $50.1 billion CAPEX plan throughout 2026.
• If this happens: The Amazon SMR partnership moves from concept to a concrete project plan. Watch this: Look for key milestones in 2026, such as site selection announcements or pre-application filings with the Nuclear Regulatory Commission (NRC).
• These could be happening: The Virginia State Corporation Commission’s (SCC) decision on the proposed 1 GW Chesterfield gas plant will signal the state’s true priority. An approval would prioritize immediate reliability for data centers, while a rejection could intensify the push for nuclear and energy storage solutions.
• These could be happening: The Virginia General Assembly could introduce new legislation building on bills like SB 253 to further refine how grid upgrade costs are allocated. This would directly impact the financial models for both Dominion and data center developers considering new projects in the state.
