What flows through a data centre — and how it pays

A data centre leases IT capacity — measured in kilowatts of critical power — to tenants on long contracts. Power and data flow through racks of servers; tenants pay recurring rent plus power & connectivity. With most costs fixed on a built facility, the economics turn on occupancy (lease-up), the rent achieved, and energy efficiency (PUE) — high operating leverage means margins climb sharply as the halls fill.

Power & connectivity
Why investors like it: recurring rent on long leases to creditworthy tenants is a stable, inflation-linked annuity — close to real estate but with a powerful demand tailwind (cloud & AI). Power & connectivity (recharges, cross-connects, managed services) add a stickier, higher-churn layer. With the facility's costs largely fixed, every point of occupancy and £ of rent drops almost straight to EBITDA — which is why lease-up is everything.

Illustrative model. Represents a ~40 MW IT-capacity colocation data centre operating 24×365. Revenue = leased kW × (rent + power & connectivity). Tenants' IT power is recharged; the operator bears the cooling/common-power overhead set by PUE (total facility power = IT load × PUE), so a lower PUE means a higher margin. Most other costs (staff, maintenance, connectivity, insurance, rates) are largely fixed, giving high operating leverage on occupancy. EBITDA = revenue − operating costs. The investment case is a simplified DCF: unlevered IRR discounts free cash flow to the firm (EBITDA − cash tax − capex) plus an exit on the EV/EBITDA multiple; levered IRR is the equity cash flow after debt. For illustration only — not investment advice, and not any specific asset.
