Got Power? We Do - On Your Terms
Capstone’s Energy Surplus Program (ESP) delivers scalable on-site power, integrated cooling, and resilient infrastructure so AI data centers can scale with modular, fast deployments on a “Pay as You Grow” basis.
As grid constraints, utility delays, and rising energy costs intensify, Capstone’s ESP delivers Engineered Equipment Packages (“EEP’s”) that alignwith AI data centers’ specific topology – enabling growth or expansion without shifting infrastructure costs downstream.
FACT: AI is accelerating faster than the electric grid can support. As scrutiny increases around data center energy demand, interconnection delays, and who pays for new power infrastructure, operators are rethinking how they scale without solely relying on the grid. Capstone’s Energy Surplus Program (ESP) offers a proven path forward. Beyond core power solutions, Capstone provides tailored configurations for hyperscalers, Day1 loads, station power, expansion projects requiring supplemental power or cooling, midsized power blocks for colos, cloud and mobile compute environments, and small-scale EDGE deployments. Capstone’s broad product range supports multiple approaches to deliver the right mix of on-site power and cooling.
Today’s challenge is not simply how fast data centers can grow but how they do so without overloading utilities, delaying deployment, or increasing costs for surrounding communities.
By enabling on-site generation and integrated cooling, Capstone’s ESP reduces dependence on constrained grids and empowers operators to expand capacity on their own timelines, on their own terms.
ESP Key Benefits:
-
Scalable On-Site Power: Grow from multiple megawatts to hundreds of megawatts on a campus with modular units that can scale in months, not years.
-
High Efficiency at Scale: Achieve plant efficiencies up to 85% through high-grade waste heat recovery, cutting both energy use and cost.
-
Built-In Resiliency: Multi-bay 1MW configurations provide integrated and active redundancy, ensuring uptime even as AI server loads increase.
-
Energy Surplus Creation: ESP doesn’t just meet demand; it creates surplus capacity, relieving pressure on the grid while freeing energy for compute-intensive workloads at the rack and chip level.
-
Sustainability in Action: Low-emission microturbines with optimized efficiencies reduce total carbon footprint, helping operators meet ESG goals without compromising growth.
How ESP Delivers Energy Surplus
Scaling AI data centers requires more than a single technology. It demands an integrated system that combines power generation, cooling, storage, and controls into one resilient platform. That is where Capstone’s ESP delivers.
ESP unifies proven technologies into a purpose-built architecture designed for AI-driven, high-density workloads.

Why It Matters
As utilities, regulators, and communities call for large data centers to “pay their own way,” on-site, efficient generation is quickly becoming a prerequisite, not a differentiator.
| OPERATOR PAIN POINT | ESP SOLUTION |
| Utility Delays & Grid Congestion Multi-year wait times, rising interconnection costs, and grid constraints |
Accelerated Deployment On-site power and cooling deployed in months, independent of grid expansion timelines |
| Cooling Demands AI workloads driving high-density IT loads and unprecedented cooling needs |
Integrated Cooling Absorption chillers and dry coolers turn high-grade waste heat into chilled water and cut electrical cooling loads |
| Infrastructure Constraints Multi-year wait times for new grid connections or costly upgrades |
Scalable Design Modular microturbines, battery storage, and cooling scale with demand on your schedule |
| Rising Energy Costs Volatility and increasing utility rates |
Cost Control On-site generation hedges grid price swings and optimizes total cost of ownership |
| Net Zero Pressure Renewable supply alone not enough to meet ESG targets reliably |
Sustainability in Action Low-emission microturbines and waste-heat recovery reduce emissions and progress toward net zero |
