Virginia Governor Abigail Spanberger’s landslide victory in the gubernatorial race last November was largely propelled by a compelling platform centered on the urgent need to rein in escalating electricity costs for the Commonwealth’s residents. This focus resonated deeply with voters grappling with inflation and the rising expense of daily life. A significant factor contributing to this concern is Virginia’s burgeoning role as a global hub for artificial intelligence (AI) data centers, an industry with an insatiable appetite for power. The state’s largest utility, Dominion Energy, is currently facing immense pressure to meet the projected surge in electricity demand driven by this technological expansion. Governor Spanberger, a Democrat, consistently pledged on the campaign trail to "make Virginians’ bills more affordable," a promise that formed a cornerstone of her successful bid for the executive office.
However, in a move that has generated considerable discussion and some surprise, Governor Spanberger signed a bill last month signaling Virginia’s return to the Regional Greenhouse Gas Initiative (RGGI). RGGI is a cooperative, market-based program designed to reduce atmospheric carbon dioxide (CO2) emissions from the power sector across nine northeastern and mid-Atlantic states. This decision marks a significant policy reversal, as Virginia had withdrawn from the program in 2022 under the administration of her Republican predecessor, Glenn Youngkin.
The Mechanics and Controversy of RGGI
RGGI operates as a "cap-and-trade" system. Under this framework, a declining cap is set on the total amount of CO2 emissions that participating utilities are permitted to release annually. Utilities are issued or must purchase allowances for every ton of CO2 they emit. Those who emit less than their allocated allowances can sell their surplus to others, creating a market incentive to reduce pollution. While proponents argue that these programs drive utilities towards cleaner energy sources and innovation, a frequently cited concern is that the costs associated with purchasing allowances are ultimately passed on to consumers in the form of higher electricity bills.
This inherent cost implication has placed cap-and-trade programs under increased scrutiny, particularly as the Democratic party pivots towards addressing voter anxieties about inflation. In California, for instance, some Democratic lawmakers have advocated for relaxing the state’s cap-and-invest system. Similarly, New York Governor Kathy Hochul, also a Democrat, has sought to delay the implementation of certain aspects of the state’s climate initiatives, including a proposed cap-and-trade system for emissions from buildings and vehicles, even as New York remains a member of RGGI.
Supporters’ Arguments: Protecting Consumers from Data Center Costs
Despite the perceived tension with her affordability agenda, supporters of Virginia’s re-entry into RGGI argue that the program could, in fact, shield many Virginia households from the financial burden of the data center boom. They contend that the revenue generated from the sale of pollution allowances can be strategically reinvested to lower energy bills for consumers and accelerate the transition away from fossil fuels.
William Shobe, an emeritus professor of public policy at the University of Virginia and an original architect of the RGGI program, explained the rationale. "Of course [RGGI] imposes costs on ratepayers, because we’re trying to internalize the costs that pollution is causing on everyone else," Shobe stated. "But it’s really important to make sure we don’t make a good environmental policy regressive. If you design it right, it’s another tool for reallocating the costs that data centers are imposing on ratepayers."
The 10 other states participating in RGGI collectively agree to progressively lower the emissions cap every few years. This mechanism is intended to compel utilities to invest in and adopt renewable energy sources such as solar and wind power. Since its inception in 2009, RGGI has been credited with helping member states significantly reduce their overall CO2 emissions, primarily through the displacement of coal-fired power generation with cleaner-burning natural gas.
Dominion Energy’s Role and Potential Cost Pass-Through
Dominion Energy, a dominant utility serving over half of Virginia’s residents, particularly along the populous coast, has a history of managing RGGI costs. Before Virginia’s withdrawal, the utility implemented a per-watt surcharge on customer bills to offset RGGI expenses, which amounted to approximately $5 per month for an average household. While some critics argued that Dominion did not need to pass these charges onto consumers, a representative from the company has indicated that they intend to seek to reimpose such fees now that Virginia is rejoining the initiative.
The financial dynamics of RGGI have become more pronounced in recent years. The price of a RGGI pollution permit has doubled over the past five years, rising from $8 to $16 per ton, as member states have intensified their efforts to reduce carbon emissions. Concurrently, Virginia’s energy consumption has surged by approximately 15 percent, largely attributed to the insatiable demand from the AI data center sector. According to the Electric Power Research Institute, a non-profit research firm, data centers currently account for about 20 percent of the state’s electricity consumption, a figure projected to exceed 50 percent by 2030.
This escalating demand necessitates that Virginia’s utilities will need to procure a greater volume of carbon permits from RGGI, thereby increasing the cost of generating electricity from natural gas. Even though Virginia was outside the RGGI alliance for a period under Governor Youngkin, its re-entry means it must align with the decarbonization trajectory already established by the other participating states. Andrew McKeon, executive director of the RGGI Inc. non-profit organization that manages the program, noted that Virginia is effectively returning to the program at a point where it would have been had it never left.
Reinvesting RGGI Revenue for Affordability and Efficiency
Proponents of Virginia’s return to RGGI maintain that the program’s financial structure offers a pathway to mitigate, rather than exacerbate, energy affordability challenges. The revenue generated from the sale of pollution allowances is earmarked for projects designed to reduce energy bills and promote energy efficiency. Prior to its withdrawal, Virginia utilized approximately $250 million in RGGI funds to enhance energy efficiency in low-income households. These initiatives included weatherizing homes to improve insulation and upgrading heating, ventilation, and air conditioning (HVAC) systems. Such energy-saving measures not only benefit the direct recipients but also indirectly help all customers by reducing overall demand, which can help temper energy prices. Furthermore, these efforts contribute to the broader public health benefits derived from reduced pollution from coal and gas-fired power plants.
The significant energy consumption of data centers positions them to bear a substantial portion of the costs associated with rejoining RGGI. Dominion Energy has already implemented a new rate structure for "large load" users, including data centers, requiring them to cover the majority of the costs associated with generating and distributing their substantial power needs. This measure aims to prevent these costs from being disproportionately shifted to residential customers. Professor Shobe also indicated that Virginia legislators are exploring options to modify how RGGI revenues are allocated, potentially directing a portion to assist low-income families with their electricity bills.
"It [would be] an automatic mechanism for recovering some of those increased costs and giving it back," Shobe commented. He suggested that some low-income households with minimal energy consumption could potentially see their bills decrease compared to a scenario where Virginia remained outside RGGI. It is important to note that Professor Shobe has been appointed to Virginia’s state air pollution control board, though he maintains no formal affiliation with the current gubernatorial administration.
The Pace of Decarbonization and Future Energy Mix
The question remains whether RGGI will significantly accelerate Virginia’s transition away from fossil fuels, especially given existing state mandates. The Virginia Clean Economy Act mandates that Dominion Energy phase out all its fossil fuel power plants by 2045, with provisions for continued operation only if necessary to ensure grid reliability and prevent blackouts. Over the past decade, Dominion has brought approximately 2 gigawatts of solar power online and has ambitious plans to add another 16 gigawatts over the next ten years, representing an estimated investment of around $8 billion. As of 2024, fossil fuels constituted roughly 60 percent of Virginia’s energy mix, with nuclear power and a growing solar component making up the remainder.
Dominion is also set to begin receiving power from the Coastal Virginia Offshore Wind project, the nation’s largest offshore wind farm, which is nearing completion. However, the company is simultaneously seeking approval to expand a large natural gas power plant, a move that has drawn strong opposition from environmental groups and community organizations. Notably, Dominion’s investment plans reportedly allocate more funds toward natural gas development than to solar projects. Furthermore, to meet the burgeoning demand from data centers, the utility has resorted to importing electricity from coal and gas plants in neighboring states like West Virginia and Ohio, which often have less stringent environmental regulations. Dominion has estimated that phasing out its reliance on fossil fuels to comply with the state’s clean energy law would incur a cost of $270 billion, though environmental organizations have contested these figures.
Given the stringent requirements of the Virginia Clean Economy Act and the considerable technical and financial challenges associated with maintaining a reliable, 24/7 power supply without fossil fuels, some experts express skepticism about RGGI’s capacity to expedite Virginia’s departure from natural gas.
Shuting Pomerleau, an energy analyst at the center-right think tank American Action Forum, articulated this view: "I don’t see a magic wand, we’re hitting the ceilings everywhere. I will be very skeptical if all these things combined could accelerate the decarbonization much faster than it currently already is."
RGGI as a Financial Catalyst for Clean Energy Investment
Conversely, advocates for Virginia’s return to RGGI assert that the program will exert a tangible influence on the strategic decisions of Dominion Energy and other utilities. As these companies face the necessity of investing tens of billions of dollars to meet escalating energy demand, the financial signals provided by RGGI are expected to make investments in renewable energy sources like solar and battery storage more financially attractive compared to continued reliance on fossil fuels. Jamie Dickerson, a senior policy analyst at the climate policy think tank Acadia Center, emphasized this point.
"RGGI will be a direct price signal," Dickerson stated, highlighting the program’s role in shaping market incentives and driving the clean energy transition. The economic framework of RGGI, by increasing the cost of carbon-intensive energy generation, aims to create a more level playing field for cleaner alternatives, thereby encouraging the necessary investments to power Virginia’s future in a sustainable and affordable manner.
