In water companies' draft business plan submissions to Ofwat there were significant investments related to renewable energy. Ofwat assessed the draft business plans and allowed a significant amount of renewable energy-related investment. This would lead to a 40 per cent. increase in the amount of renewable energy generated by the companies. Most of this increase comes from additional production of biogas from sludge treatment and a growth in combined heat and power (CHP) capacity.
Ofwat are currently reviewing the final business plan submissions from water companies. The outcome of their review will be made available on 23 July.
