Question 1

What is a powered shell data center?

Accepted Answer

A powered shell is a purpose-built data centre building delivered with the structure, utility service, and connectivity in place, but with the interior left as conditioned raw space. The developer delivers the envelope, the slab, the power capacity to the building and usually the fibre entry. The tenant fits out everything inside: cooling plant, electrical distribution, racks, containment, security and controls. It sits between a bare industrial building and a fully fitted turnkey suite.

Question 2

What is the difference between a powered shell and a turnkey data center?

Accepted Answer

Scope and who carries the fit-out. A turnkey suite arrives complete — cooling, UPS, distribution, containment, commissioning — and the tenant brings only hardware. A powered shell delivers the building and the power, and the tenant designs and builds the interior to their own standards. Turnkey costs more per kilowatt and moves faster; powered shell costs less and gives the operator full control over their cooling and electrical topology, which matters if you have your own reference design.

Question 3

How much does a powered shell data center cost?

Accepted Answer

Any figure quoted without a site is guesswork, because the number is driven by the things that differ most between sites: how much power is actually available and when, land and construction cost in that market, and how much civil and utility work the shell needs. The more useful question is what the delivery date is worth. A cheaper shell that cannot energize for five years while it waits in an interconnection queue is not cheaper in any sense that matters to an operator with hardware on order.

Question 4

Is a powered shell available faster than a build-to-suit?

Accepted Answer

Usually yes, because the building work overlaps with the tenant fit-out design rather than following it. But the honest constraint is rarely construction — it is power. Across much of North America a new large load waits five to seven years for a utility interconnection, and no amount of construction speed compresses that. A shell is only genuinely fast if the power is already secured.

Question 5

How is a GRECO powered shell different?

Accepted Answer

The power is generated on the campus rather than drawn from a utility connection that has to be granted first. Solid oxide fuel cells below roughly 20 MW and combined cycle above it sit behind the meter, so delivery is a construction schedule rather than a queue position. The other difference is heat: halls are engineered for liquid cooling from the outset, and the recovered heat is sold into district energy at 50 °C instead of rejected.

Question 6

What lease structure does a powered shell normally use?

Accepted Answer

Typically a long-term triple-net lease, priced either per square foot or per kilowatt of committed critical capacity, with terms commonly running ten to fifteen years to underwrite the development. The tenant carries the fit-out capital and usually the operating costs inside the demise. Exact structure is a negotiation rather than a published rate, because it moves with the capacity committed and the phasing.
