The exponential growth of data centers—driven by cloud computing, streaming services, and emerging technologies like artificial intelligence—presents a unique challenge for electric utilities. Unlike more predictable commercial or industrial customers, data centers often have:
- High and “Lumpy” Demand: Large capacity requirements that can ramp up quickly.
- Load Uncertainty: Actual electricity usage may deviate from forecasts if data center operators consolidate workloads, adopt more efficient chips, or shift operations elsewhere.
- Critical Reliability Requirements: Data centers must maintain near-constant uptime, making uninterrupted power supply essential.
These attributes raise important questions for utilities about how much capacity to build and how to recover infrastructure costs if actual data center load doesn’t match initial projections.
Utility Strategies to Address Data Center Loads
In response to potential risks and opportunities, utilities are exploring the following high-level strategies:
-
Contractual Safeguards
Ensuring data center operators pay their fair share of infrastructure costs, often through minimum demand charges or “take-or-pay” agreements that protect the utility (and other customers) if load declines. -
Regulatory Alignment
Working within regulatory frameworks—whether that’s at a state utility commission or another authority—to justify cost recovery proposals, rate structures, and large capital investments needed to serve data centers. -
Flexible System Design
Building capacity in modular phases, using scenario-based forecasts, and incorporating the possibility of distributed energy resources (DERs). This approach helps utilities avoid overbuilding and reduces the risk of stranded assets. -
Proactive Stakeholder Engagement
Maintaining open communication with local authorities, planning agencies, and data center developers to anticipate changes in load and technology, and to coordinate on timelines and infrastructure needs.
Spotlight on Flexible System Design
Among these strategies, flexible system design has emerged as a standout approach to balancing the potential for massive new demand with the uncertainty of load growth. By phasing infrastructure upgrades and building in modular components, utilities can more easily adapt to real-world conditions.
Key elements of flexible system design include:
- Phased or Modular Infrastructure Builds
Staging substation and feeder expansions as demand materializes, rather than all at once. - Flexible Use of Distributed Energy Resources (DERs)
Integrating battery storage, local generation, or demand response to offset peak loads and increase reliability. - Advanced Monitoring, Control, and Data Analytics
Leveraging smart grid technologies to anticipate load fluctuations and optimize system performance in near real-time. - Rate Design and Cost-Recovery Mechanisms
Structuring charges so that data center customers pay for the capacity they reserve, protecting utilities from stranded costs. - Collaboration and Contingency Planning
Working with system operators, other utilities, and community stakeholders to ensure enough capacity is available when needed, without overspending.
Each elements addresses data center loads differently.

Final Thoughts
The data center boom presents significant opportunities for utilities in terms of new load and revenue, but it also carries substantial risks around investment recovery and operational reliability. By taking a flexible approach—both in infrastructure development and in risk-sharing contracts—utilities can better align with customer needs, regulatory expectations, and rapidly evolving technologies. Ultimately, these strategies foster a more resilient, modern grid capable of powering the data-driven future.
