What changes from 250 kW to 5 MW

250 kWPrivate cage or suite options may still exist. Facility minimums and density matter.
500 kWDedicated suite economics, ramp and adjacent expansion become central.
1 MWContiguous capacity, utility status and construction dependencies narrow the field.
2 to 5 MWWholesale phases, powered shells or future delivery paths are increasingly likely.

Capacity for lease needs a dated delivery path

For operating capacity, verify usable IT kW, room or suite, cooling, electrical topology and the work needed to turn up service. For capacity under construction, document utility status, equipment procurement, commissioning milestones and the provider's contractual delivery obligation. Announced capacity without those details is not a dependable project option.

Commercial terms to normalize

  • Committed usable IT kW, metering basis and power overage treatment
  • Initial ramp, future ramp and take-or-pay milestones
  • Base recurring charge, utility pass-through and PUE treatment
  • One-time fit-out, distribution, security and commissioning charges
  • Annual escalators, renewal pricing and early termination rights
  • Adjacent expansion rights and consequences of a late future phase
  • Cross-connect, carrier, cloud and remote-hands costs
  • Service levels, maintenance rights and force majeure allocation

Compare four major markets

Ashburn

Exceptional network depth with very tight near-term availability and premium pricing.

Dallas

Large development pipeline and strong scale, with interconnection and prelease status to verify.

Atlanta

Rapid growth and East Coast reach, with immediate capacity tighter than long-term generation plans imply.

Chicago

Central geography and dense connectivity, with utility delivery timelines increasing the value of energized capacity.
