Try our energy calculator now! Find out how Green DSR can bring CO2 reductions and financial savings to your organisation.

Our energy opportunity calculator is very simple and easy to use.

In just a few seconds, it will show you the untapped potential in your facility and the benefits your organisation could enjoy from participating in Green Demand Side Response.

All you will need is knowledge of your organisation's typical monthly electricity spend - this will be available on the bill from your current supplier.

Enter the value and the calculator will do the rest, producing an estimate of:

  • The carbon emissions reduction Green DSR will deliver (kgs)
  • The financial benefit of Green DSR made up of cost savings AND the income generated from trading the demand-side response savings with National Grid ESO
