ELECTRICITY

LET’S GET STARTED
WHERE ARE WE NOW?

Scottish Water delivers vital water and wastewater services in Scotland and uses 576GWh pa of electricity, leading to 160ktCO2e pa.

We currently generate and consume 53GWh of renewable electricity on our assets, displacing
the use of grid electricity.

We also host renewable generation of 831GWh per annum for others on our land. This is exported to the National Grid, supporting UK emissions. We aim to significantly increase this, playing our part in supporting a flourishing Scotland.

These tables illustrate the key activities we are exploring to reduce our electricity emissions.

We will keep these under review with our expert advisory panel.
