GRECO Energy
A powered shell is a purpose-built data centre building delivered with its structure, utility service and connectivity in place, but with the interior left as conditioned raw space. The developer provides the envelope and the power; the tenant designs and builds everything inside it.
It sits between a bare industrial building, which is cheaper but has no meaningful power, and a turnkey suite, which arrives fully fitted, costs more per kilowatt and leaves the tenant far less control over cooling and electrical topology.
Most powered shells are gated on a utility interconnection: the building is finished and sits idle until the connection is granted. A GRECO shell generates power on the campus behind the meter, so the delivery date is a construction schedule rather than a position in a queue that runs five to seven years across much of North America.
