Data Center 24/7 Renewable Matching Calculator

Evaluate hourly renewable matching performance by combining annual load, aligned renewable supply, storage dispatch, and fully matched hour counts.

Total electricity consumed over the year by IT and supporting systems.
Renewable MWh delivered in the same hours as the load (post-alignment).
Battery or thermal discharge allocated to fill gaps. Defaults to 0 if blank.
Count of hours in the year where renewable supply equalled or exceeded load. Defaults to reported load hours when blank.

Operational planning aid. Pair with detailed hourly telemetry before making procurement or disclosure commitments.

Examples

  • 380,000 MWh load, 320,000 MWh hourly matched, 22,000 MWh storage, 6,100 fully matched hours ⇒ Energy matching score 90.00% | Shortfall 38,000 MWh | Surplus 0 MWh | 69.63% of hours fully matched (6,100 hours).
  • 250,000 MWh load, 210,000 MWh matched, storage left blank, fully matched hours blank ⇒ Energy matching score 84.00% | Shortfall 40,000 MWh | Surplus 0 MWh | 84.00% of hours fully matched (7,358 hours).

FAQ

Should I include market purchases backed by renewable certificates?

Only if the certificates are time-matched to the delivery hour. Otherwise treat them as unmatched energy and leave them out of the hourly matched input.

How do I treat co-located generation with curtailment?

Use net MWh actually consumed during matching hours. Excess production spilled to the grid should be excluded unless storage shifts it into deficit hours via the optional storage field.

What does the shortfall represent?

Shortfall quantifies the MWh still served by non-matched sources. Many organisations convert it to residual emissions using the grid emission factor, similar to the hydrogen carbon intensity workflow.

Additional Information

  • Result unit: percentages with supporting MWh shortfall and surplus values.
  • Storage discharge defaults to zero, so only simultaneously matched renewables count unless you add battery dispatch.
  • Hours fully matched default to the energy score applied to 8,760 hours when no data is provided, offering a quick proxy.
