How does PUE change a Navi Mumbai data centre's Scope 2?
Scope 2 follows total facility electricity, not IT load alone. PUE is total facility energy divided by IT energy, so at a PUE of 1.5 every 100 kWh of IT draw means 150 kWh billed, all counted at 0.710 kg CO2 per kWh on the location-based method.
The relationship
ISO/IEC 30134-2 defines PUE as total facility energy over IT equipment energy. Cooling, power conversion and lighting are the gap between them, and all of it is purchased electricity in Scope 2.
Two methods
Report location-based at the grid factor and, where the site buys renewable electricity with qualifying evidence, a market-based figure too.
Worked example: one month (illustrative inputs)
- IT energy: 1,000,000 kWh; total facility energy: 1,500,000 kWh
- PUE: 1,500,000 / 1,000,000 = 1.5
- Scope 2, location-based: 1,500,000 x 0.710 = 1,065,000 kg CO2
Quantities are illustrative; use metered IT and facility energy.
What Senseible does here
Senseible reads each site's monthly electricity bills into a dated Scope 2 record, keeps renewable purchase documents beside them for market-based reporting, and records diesel for backup generators as Scope 1. Customer shares use the allocation key you enter.
