In an effort to further reduce its carbon footprint, Southern Water is turning to sewage to boost renewables generation. At present, the water and sewage company generates 17 percent of its electricity demand from 16 combined heat and power (CPH) sites, with total renewable electricity generation currently totaling 48.3GWh. With new Veolia combined heat and power (CPH) engines installed at its treatment facilities in Hampshire and Kent, Southern Water will be well equipped to expand its renewables portfolio.
The new projects at Hampshire and Kent have seen Veolia implement project design, installation and operation of biogas cogeneration units, which converts wastewater from Southern Water’s 39,000 kilometers of sewage networks into biogas through anaerobic digestion (AD).
