Veolia has helped bring Scottish Water within touching distance of its target of energy self-sufficiency at its Seafield Wastewater Treatment Works (WwTW), the largest treatment works in the east of Scotland. Since 2015, Veolia has extended the site's capability to generate its own energy from 55% to around 85% in 2017 by boosting the renewable energy derived from a combination of anaerobic digestion of sludge and biogas-fired combined heat and power (CHP) plants. In fact, full self-sufficiency has already been achieved at various points during 2017, when Seafield used no electricity from the Grid.
