Powering Tomorrow: Meeting Data Center Needs and Ensuring Grid Sustainability

March 26, 2025

Data centers (DC) present a myriad of complex challenges and opportunities. There are no simple solutions, and the stakes are high, from startup investments, rates, and potential stranded costs to the type of energy powering these facilities and their community impact. Siting decisions, whether urban or remote, bring their complications, compounded by regulatory ambiguity and potential NIMBY opposition. As electricity demands grow, the pressure to create a resilient, sustainable grid becomes increasingly critical. This is not a puzzle for the distant future; it’s a pressing challenge in real-time in communities nationwide.

What’s driving the urgency? The economy’s electrification, the explosive growth of AI, and emerging technology in cloud computing all require enormous amounts of energy. Data centers have become the backbone of our digital economy. Yet, their skyrocketing power needs are pushing the limits of our grids and infrastructure and raising questions about their benefit to the communities in which they’re located.

“In the past, large electric loads often brought additional economic benefits, namely jobs, which utilities could factor into their rate structures. However, data centers typically create few new jobs, complicating rate structuring decisions.”

Another Twist

In planning load growth, utilities have relied on past trends, but DCs bring a new dynamic to the equation. Their energy needs are often immediate, introducing complications around timing and costs. Forecasting power demands is not easy in a rapidly evolving industry with little history to draw from. There is uncertainty over how much power will actually be required. This leads to the million-dollar question: Who is responsible for DC energy costs? Will local ratepayers see increased rates? Will the DC have a different rate (as TVA is considering)? And if projections miss the mark, who absorbs the stranded costs if the DC isn’t built or goes under? These issues underscore the need for close collaboration with stakeholders, innovative solutions, and clear accountability.

Effective collaboration among DC owners, utilities (including water), local officials, and community members is essential for addressing shared challenges and competing priorities during early planning. DCs require proximity to power sources, so siting is a key consideration. Location introduces unique complexities, whether in a remote area or near a population center.

Electric utilities are tasked with ensuring reliable power for all customers, yet rising DC energy demands raise concerns about whether critical facilities like hospitals, schools, and emergency services might face competition for power during outages. Another fundamental issue to consider is whether valuable local investments, resources, and time are diverted from broader public needs to serve large commercial entities, i.e., should limited resources be used to build a new walk-in health clinic or a data center. Utilities must navigate these complexities by fostering discussions on resource allocation that balance community benefits with industry growth.

Hydroelectric power production is both reliable and renewable which makes it an attractive option to data centers who are eager to tout those features.

Then and Now

Even before a DC is built, key questions arise about the type of energy it will use and who will supply it. Initially, DC owners placed a premium on having their DCs run on clean energy. However, as the number of DCs has grown and their energy demands have surged, many owners have shifted from a preference for clean energy to accepting any available power to meet immediate needs.

Complicating matters further, the question of who provides the power has become more fluid. In some cases, DC owners come to the planning table with their energy sources, a choice that can spark debate in communities prioritizing sustainability. The immense energy demands of DCs remain one of the industry’s most significant challenges, but they also present opportunities for innovation, such as:

AI and Automation
- Leveraging AI to optimize energy use by forecasting demand and adjusting operations in real-time
- Automating cooling and power distribution systems to boost efficiency
Demand Response Programs
- Shifting non-essential computing tasks to off-peak hours to ease grid strain
- Partnering with utilities to balance grid loads during high-demand periods
Balancing Reliability and Sustainability
- Adoption of microgrids and decentralized power generation to enhance reliability
- Deploying battery storage systems to harness excess renewable energy for peak-use times
- Exploring emerging technologies like green hydrogen for sustainable, long-term energy storage

These innovative approaches underscore the critical importance of balancing the energy needs of this growing industry with sustainable and community-focused solutions.

After three decades of progress fueled by market forces, growing demand, and federal support, the future of U.S. renewable energy is less clear.

A New Playbook is Needed

Shifting political leadership and uncertainty around future energy policies continue to create challenges for utility operations and investments. Issues that were once thought of as distant 2050 problems are now 2025 challenges. This fast-evolving landscape underscores the urgent need for innovation and collaboration across the energy sector. The solutions of the past are outdated. A new, forward-thinking approach and playbook are needed. One that supports the needs of a growing U.S. economy yet reflects fairness for ratepayers, local communities, sustainability, and resilience for the future.
