How much power reaches the racks?

Using the infrastructure MW planner

This planner turns a facility power allocation into an estimate of the power left for IT equipment. It is for project owners, operators and analysts who need to compare assumptions before discussing a site, cooling change or equipment plan. It keeps the arithmetic visible: usable IT load equals facility allocation minus non-IT overhead. The result is a scenario calculation. It does not establish a utility commitment, commissioned capacity or measured equipment performance.

Start by choosing a consistent power boundary. The facility allocation should describe the total power available inside that boundary, expressed in megawatts. Baseline non-IT overhead covers cooling and other facility systems inside the same boundary. Enter the scenario overhead using the same definition. Mixing a utility connection figure with an IT-only figure can create an attractive result that has no physical meaning. Keep the source and date for each input beside your project notes.

For example, the illustrative defaults allocate 250 MW to the facility. A baseline overhead of 50 MW leaves 200 MW for IT. A scenario overhead of 42 MW leaves 208 MW. The difference is 8 MW reallocated to IT in the arithmetic. That number does not mean the project has gained a new utility connection or that a cooling product has achieved an 8 MW saving. A real claim needs measurements taken across the same boundary under comparable operating conditions.

Change one assumption at a time and compare the outputs. If scenario overhead rises above the baseline, the reallocated figure becomes negative: more power is going to systems outside IT. The planner rejects a zero or negative facility allocation, negative overhead and overhead greater than facility allocation. Check the status message when results are unavailable. Use project-specific figures rather than treating the defaults as a benchmark.

Before making an investment or engineering decision, review the scenario with the responsible engineering team. Check reserve margins, distribution losses, redundancy, equipment derating, cooling conditions and the difference between nameplate and sustained load. This compact planner does not model those factors separately. Use the power project portal to organize a broader review, and retain the underlying disclosures and operational evidence when sharing results.
