The challenge

Land and power, but no data center.

A renewable energy developer held a strong site and deep expertise in solar power, but had never designed or built a data center. To decide whether to commit capital, and to bring partners and investors along, they needed more than a concept. They needed a decision package an investment committee could actually underwrite.

The site had to make sense technically and financially: the right capacity, the right power architecture for an on-site renewable supply, a defensible cost basis, and a clear view of the risks before anyone broke ground.

Our role

Blank site to investor-grade package in six weeks.

PGCIS led the advisory and basis-of-design engagement. We started with requirements and feasibility, then developed a conceptual architecture, BIM model, and basis of design across eleven CSI MasterFormat divisions, from civil and structural through electrical, mechanical, controls, and security.

Our concept paired a behind-the-meter microgrid - 161 kV utility service, roughly 12 MW of on-site solar, and standby generation - with three-loop cooling for liquid-cooled AI racks. It targeted a 1.4 PUE and zero water use.

The investor package included a 6 MW to 24 MW phased plan, a costed risk register, renders, single-line diagrams, and equipment schedules. Specialist subconsultants supplied grid and market studies.

Outcomes

What happened

  • Delivered a complete, investor-grade decision package, design plus economics plus risk, in a six-week engagement
  • Defined a Tier III, concurrently maintainable facility concept on an N+1 basis, targeting a 1.4 PUE and zero water for cooling
  • Identified $6.5M to $8.5M in capital savings through a consolidated power architecture
  • Identified a further $0.9M to $1.25M by eliminating raised flooring
  • Modeled project economics that lifted internal rate of return from roughly 12 percent to a 15 to 19 percent range under a power pass-through structure
  • Bounded total project risk exposure to a defined $3M to $8M range, with mitigation paths for interconnection, geotechnical, and permitting risk
