Energy availability now shapes where and how digital infrastructure gets built

AI-driven computing demand is colliding with a slower-moving physical reality: transmission infrastructure, utility interconnections, transformer manufacturing, and fuel delivery systems cannot expand at the same pace as hyperscale growth. What once felt like a regional utility issue is becoming a defining operational constraint for the next generation of data centers.

Bill Kosik, PE, CEM, LEED AP, Mission Critical Sector Leader at HED, contributed perspective on the growing shift toward on-site and hybrid energy strategies. His comments focused on the practical limits behind these solutions, from natural gas deliverability and transformer lead times to the regulatory complexity surrounding large-scale off-grid systems. Rather than treating alternative power as a shortcut, the discussion framed it as a new layer of infrastructure coordination.

In Data Center Knowledge, contributor Nathan Eddy examines how operators are adapting to widening gaps between projected utility capacity and actual delivery timelines. The article explores fuel cells, gas turbines, battery storage, and emerging regulatory pressures tied to gigawatt-scale AI campuses, placing the industry’s energy conversation within a broader transformation of digital infrastructure planning.

Rethinking Energy: How Data Centers Are Adapting to Grid Constraints

As grid delivery timelines struggle to keep pace with the rapid growth of AI data centers, operators are turning to on-site power solutions. Experts weigh in on the challenges and opportunities of this transformation.

With AI workloads driving unprecedented energy demands, data centers are facing a critical choice: adapt to grid constraints or risk falling behind. As a result, operators are increasingly taking control of their energy supply, signaling a major shift in how facilities are powered.

A recent report from Bloom Energy reveals a dramatic shift toward on-site power solutions, with one-third of hyperscalers and colocation providers planning fully self-powered campuses by 2030.

The report shows a widening gap between what data center operators expect from utilities and what utilities say they can realistically deliver.

Across major hubs such as Northern Virginia, the Bay Area, and Atlanta, utilities are projecting power-delivery timelines up to two years longer than hyperscalers and colocation providers anticipate – a mismatch that has grown worse over the past six months.

Developers are also rethinking how power is delivered inside facilities. Nearly half of respondents (45%) said they expect to adopt direct current (DC) distribution architectures in new data centers by 2028, signaling a shift away from traditional alternating current (AC) designs as operators seek higher efficiency and better alignment with modern IT loads.

Power Play

In response to the report, Bill Kosik, PE, CEM, LEED AP, mission-critical sector leader for HED, an integrated architecture and engineering company, told Data Center Knowledge that for gigawatt-scale data centers over the next decade, gas turbines and gas engines are the most “bankable” on-site firm-power option.

However, he cautioned that the capacity and deliverability of natural gas become critical challenges in this transition.

“At 500 MW, onsite fuel cells or turbines look like a new power-plant-class load, meaning constrained regions may require new laterals, compression, or pipeline upgrades with multi-year lead times,” he explained.

He added that fuel cells can scale in large blocks where gas is robust, and emissions permitting is manageable.

“Long-duration storage is a force multiplier, not a fuel substitute, as it bridges events and trims generator run-hours,” Kosik said.

He added that nuclear-powered small modular reactors (SMRs) are strategic, but unlikely to scale broadly before 2036.

Technical, Regulatory Barriers

Kosik cautioned that fully off-grid or hybrid data center power faces hard physics and even harder tariffs. While roadmaps push renewables and storage, designs of this nature can require an order of magnitude more land than the facility itself.

“The most universal chokepoint is transformers,” he said.

Large MV/HV units carry the same multi-year lead times that are slowing utilities, so onsite doesn’t magically bypass supply chains.

Gas or fuel-cell hybrids add firm transport and backup fuel requirements; hydrogen raises production, storage, leakage, and safety complexity.

Meanwhile, regulators are tightening rules: FERC is forcing large co-located loads to be fully visible in planning and to pay for transmission, regulation, and black start, limiting “netting away” impact through the late-2020s transition.

Challenges and Opportunities

As the data center industry continues to grapple with grid constraints, the shift to on-site power solutions presents both challenges and opportunities.

While technical and regulatory barriers remain, the growing adoption of innovative energy strategies signals a transformative moment for the sector. The question now is not whether operators will adapt, but how quickly they can overcome the hurdles to power the AI-driven future.
