Does an ice bank or chilled water storage tank cut my Scope 2 emissions?
Usually not on the location-based method. Storage shifts chiller load to night, but India's grid factor is one annual average (0.710 kg CO2 per kWh), so the same kWh give the same CO2. Making ice can even use more kWh. It can still cut cost and peak demand.
When it can help
- If storage lets you use more of your own solar output.
- Under the market-based method, if a contract supplies renewable power at the hours you charge.
- If it lets a chiller run at its best load instead of cycling.
When it can hurt
- Ice making runs chillers at lower temperatures, so efficiency drops.
- Tank losses add kWh.
What Senseible does here
Senseible reads fuel invoices and electricity bills and applies IPCC 2006 factors and the CEA grid factor (0.710 kg CO2 per kWh), so you can compare Scope 1 and 2 before and after a change from the documents themselves.
