Local authority water services use approximately 350GWh of energy and emits 180,000 tonnes of CO2.
Initial indications from the Working Group reveal 30% - 50% savings in energy use are achievable through the use of high efficiency pumps. The Water Services Working Group will aid local authorities to achieve these substantial savings.
Energy Use in Water Services
Energy used in local authorities water services varies between 55% and 70% of the total energy consumed by local authorities.
Per Capita energy consumption in several surveyed counties shows an average energy consumption of over 105 kWh per person on water and waste water.
Potential Energy Efficiency Opportunities
Many water pumping stations and treatment plants have never managed energy – with the exception of the winter demand reduction schemes. Significant energy opportunities however do exist.
For example, work underway in Kerry and Tipperary has yielded significant savings (20% - 40% in pumping energy efficiency) in several key categories.
