Powering the Data Center Boom:

No One-Size-Fits-All Solution
The explosion of artificial intelligence, cloud computing, and high-density computing has driven a global data center boom. These facilities are the backbone of modern digital infrastructure, but they come with a challenge: how to power them reliably and affordably. Data centers are energy-intensive, and their demand is growing at a rate that is putting real pressure on existing grids.
While the public may not think about where the electricity for their data storage or AI applications comes from, the companies building and operating these data centers have to. And they have options—each with tradeoffs depending on market conditions, grid constraints, and the local energy landscape.
Buying Power from the Grid
The simplest way to power a data center is to buy electricity from the grid, just like any other large commercial or industrial user. In deregulated markets, companies can shop for power through retail suppliers, negotiate contracts, or even enter into power purchase agreements (PPAs) with renewable energy developers. In regulated markets, they are typically subject to standard utility tariffs, which may or may not be favorable depending on demand charges, peak pricing, and rate structures.
Market-based purchasing allows flexibility, but it also introduces volatility. Energy prices fluctuate based on fuel costs, transmission congestion, and seasonal demand swings. Many companies are seeking long-term contracts or hedging strategies to manage this risk, but even then, they are still dependent on the grid’s reliability.
Collocated Generation: On-Site or Nearby Power
Another approach is to build power generation close to the data center itself. This could be in the form of natural gas turbines, fuel cells, combined heat and power (CHP) plants, or even nuclear small modular reactors (SMRs) in the future. Collocated generation provides independence from market fluctuations and can serve as a standby power source if the grid fails.
Some data centers have opted for dedicated renewables, such as solar and wind, but these intermittent sources require either substantial battery storage or a hybrid system with another dispatchable power source. Locally available energy resources—such as access to hydropower in the Pacific Northwest or nuclear energy in Virginia—play a major role in determining what’s feasible.
Dual-Purpose Power: Strengthening the Grid
A third model is emerging: data centers investing in power generation that not only serves their own needs but also contributes to overall grid stability. This can take the form of grid-interactive backup power, where a facility’s on-site generation operates as a peaker plant when the grid is stressed.
This could be a game-changer in markets with tight capacity. In Texas, for example, some data centers are exploring natural gas microgrids that can dispatch excess power to ERCOT during peak demand events. In other areas, large-scale battery storage or demand response programs could allow data centers to adjust their power consumption in real time to support the grid.
Interconnection, Markets, and Local Constraints
All of these solutions depend on one critical factor: interconnection. The ability to connect to the grid—whether to draw power, supply excess electricity, or simply ensure reliability—can be a lengthy and expensive process. Transmission congestion, permitting challenges, and a backlog of interconnection requests in regions like PJM and MISO are creating delays that can stretch for years.
Market prices also matter. Energy-intensive industries like data centers are gravitating toward regions with historically lower electricity prices, such as parts of the Southeast, where vertically integrated utilities have a more stable cost structure. But as demand rises, prices will adjust, and the cheapest regions today may not stay that way forever.
Then there are local resources. A location with abundant hydropower may find it more economical to sign a PPA with a utility, while a data center in West Texas might be better off pairing solar with battery storage. Zoning laws, air permitting for fossil-fuel-based generation, and community acceptance also play a role.
There’s No Universal Answer
The reality is, there isn’t a one-size-fits-all solution to powering data centers. The best approach depends on a complex mix of interconnection timelines, market prices, local resource availability, and regulatory considerations. Some companies will buy power from the grid, others will build their own generation, and some will look for hybrid models that balance reliability, cost, and sustainability.
As the data center boom continues, energy infrastructure will have to evolve alongside it. The companies that can navigate this complexity and make informed, context-specific decisions will be the ones that succeed in keeping the digital economy running.
