Data center future development capacity measures megawatts of additional buildable capacity beyond projects already under construction, under the issuer's stated land and power assumptions.

It is a longer-dated development-runway measure, not current operating capacity.

Future capacity shows what the platform could build next

Digital Realty reported more than 5 gigawatts of additional future development capacity as of March 31, 2026.

The company also broke that capacity into sites with more than 100 megawatts, 25 to 100 megawatts, and less than 25 megawatts of buildable capacity.

That distribution helps investors distinguish hyperscale campus runway from smaller incremental expansions.

Buildable capacity still carries execution risk

Future capacity may depend on utility interconnection, permitting, land development, capital availability, customer demand, and construction sequencing.

It should not be treated as committed supply or a guaranteed future revenue base.

Power access can be more important than raw land

A large land bank has limited economic value without a credible path to electrical capacity.

Data-center operators therefore increasingly discuss future capacity in megawatts rather than only acres or buildings.

Primary-source examples

Data center future development capacity is most useful as a buildable power-and-land runway measure. Pair it with current construction, pre-leasing, capital spending, and market-level power constraints.

Part of the Data Center Operating Model

Connect bookings, in-place rent, utilization, interconnection, renewal pricing, signed-not-commenced backlog, development capacity, pre-leasing, future buildable capacity, stabilized yield, construction cabinets, and commencement timing to understand data-center growth economics.

How the model fits together
  • Capacity and recurring monetization: Cabinet utilization shows how much Equinix cabinet capacity is billed. Digital Realty annualized rent and Equinix interconnection revenue are separate recurring-revenue lenses, so they add monetization context without forming a standardized cross-company formula.
  • Bookings, backlog, and repricing: Equinix Annualized Gross Bookings capture near-term recurring revenue expected to start within 90 days, while Digital Realty signed-not-commenced backlog captures future annualized GAAP base rent awaiting lease commencement. Renewal rental-rate change then shows repricing on expiring Digital Realty leases. These measures describe different stages and must not be treated as interchangeable.
  • Development capacity and lease conversion: Capacity under construction and sellable cabinets under construction show near-term supply being built, while future development capacity shows longer-dated buildable runway. Pre-leased development percentage shows how much construction is already spoken for, estimated stabilized development yield frames expected economics at maturity, and signed-lease commencement lag shows how quickly bookings convert into in-place rent. These issuer-defined measures add development and lease-conversion context rather than forming a standardized cross-company formula.
