GAS AND
FUEL OIL

LET’S GET STARTED
WHERE ARE WE NOW?

Scottish Water and its PFI partners use 199GWh of gas and fuel oil per year.

The majority of the gas is used in the thermal drying and processing of wastewater sludge.

Fuel oil is used for standby generation of power at our assets in the event of power supply problems.

The remaining gas is used for heating in our buildings.

This leads to 38ktCO2e per annum.

These tables illustrate the key activities we are
exploring to reduce our gas and fuel oil emissions.

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

Maximising the energy we recover from bioresource

UP TO

2025

• Consider rationalisation of buildings post COVID-19.

UP TO

2030

UP TO

2040

• Identify, assess and implement activities to replace sludge drying technology and alternatives to gas for sludge processing.

• Delivery of new solution at Daldowie to maximise value of bioresource.

• Maximise renewable generation from bioresource.

• Identify, assess and implement activities to maximise value of bioresource at returning PFI assets.

• Identify, assess and implement alternative technologies to replace standby generation on our assets (e.g. battery power).

• Complete implementation
of alternative technologies
to replace standby generation on our assets.

• Identify, assess and implement renewable heat sources for our buildings.

• Complete implementation of renewable heat sources for our buildings.

• Deliver Juniper House refurbishment as a net zero emissions building.
