Data centers now enjoy a close alliance with coal and natural gas power stations
In a rapidly digitalizing world, tech companies are increasingly investing in nuclear capacity, raising concerns about the potential replacement of carbon-free power with dirtier forms of generation. This shift is particularly evident in regions like Virginia, where at least 175 hyperscale data centers are operational or proposed, contributing significantly to the region's energy demand.
According to the U.S. Department of Energy (DOE), data centers are responsible for at least 65% of projected load growth in Virginia, Georgia, and South Carolina. By 2030, data centers alone are expected to drive a demand increase of at least 50 GW, potentially up to 100 GW, posing a significant challenge to the transition to a cleaner grid.
As fossil fuel power plants retire, the strain on the grid increases due to the lack of replacement with reliable, baseload power. While renewable resources like wind and solar offer carbon-free power, they face limitations such as weather dependency and lower capacity factors. This could lead to reliability issues, including increased risk of outages, especially under extreme weather conditions aggravated by climate change.
To mitigate these impacts, several regulatory and policy measures are being proposed or implemented. For instance, the Federal Energy Regulatory Commission (FERC) has streamlined approvals for natural gas infrastructure to support stable supply, recognizing the need for firm capacity to meet data center loads.
In some states, data centers are being encouraged to co-locate with onsite generation facilities, such as natural gas and nuclear plants, to reduce grid stress and improve local reliability. States are also exploring policies that support a sustainable yet reliable energy future, weighing fossil fuel retirements, data center demands, community impacts, and environmental goals.
National-level energy emergency declarations have also been used in the past to prioritize fossil fuel development to meet rising demand, helping counterbalance grid risks posed by retiring plants and surging data center loads.
However, the rising demand from data centers is not without controversy. For example, the tariff in North Carolina has been controversial, as it could allow data centers to subsidize renewable energy development that would have occurred anyway. Meanwhile, the delay in the retirement of fossil fuel generators overwhelmingly harms Black and brown communities.
In response, some states are proposing measures to protect ratepayers from data center-driven costs. For instance, Duke Energy in North Carolina has approved a green tariff proposal for data center customers to accelerate solar energy developments. California, home to the world's largest data center market, has proposed bills that would incentivize data centers to draw at least 70% of their energy from renewable sources and require public sharing of energy usage.
As the demand for data centers continues to grow, striking a balance between economic growth and environmental sustainability will be crucial. Ensuring sufficient reliable power infrastructure through streamlined natural gas projects, onsite generation requirements, and strategic support for baseload resources will be key to maintaining grid stability.
