Demand side responses to electricity supply are being incentivised by HM Government and the National Grid to manage restricted grid capacity. UKWIR investigated the potential for demand side energy management in the UK water industry and its challenges and constraints. The principal challenge to water companies in deploying demand side management is that diurnal peak demands for water and electricity coincide.

The UK Water sector needs to proactively pursue and systematically implement value recovery from power use to maximise benefits available. An estimate of benefits of demand management deployment based on interventions in water and wastewater tested in this study produced a sector benefit total of £84million per annum for England and Wales. This opportunity for TOTEX reduction for both water companies and the water sector will require a shift in priorities towards investment in improved flexibility, controllability and energy efficiency to optimise processes and plant.

The Links and Benefits of Water and Energy Efficiency Joint Working

Reference: 12/CL/11/6

Published Date: 20/12/2012

This project was implemented to i) provide the water industry with firm estimates of the energy efficiency and carbon emission reductions associated with household water efficiency measures; and ii) identify how potential barriers to engagement with other stakeholders involved in promoting energy efficiency could be overcome, optimising benefits and minimising risks for all parties. A literature review identified evidence of measured water, energy and carbon savings associated with water efficiency activities. This evidence was used as the basis for modelling energy and carbon savings from retrofits of the most commonly installed water efficiency devices. Results are presented with confidence limits to reflect uncertainty. A stakeholder engagement exercise obtained feedback on the drivers, barriers and solutions associated with delivering joint water and energy efficiency initiatives. A number of specific recommendations are made based on the study findings that will help enable improved joint delivery of energy and water efficiency programmes.

Energy Efficiency in the Water Industry: A Compendium of Best Practices and Case Studies - Global Report

Reference: 10/CL/11/3
ISBN: 1 84057 571 9
Published Date: 19/10/2010

Energy consumption by the water sector has increased considerably as a consequence of the implementation of new technologies to meet tightening potable water and effluent quality standards. The price of energy around the world has also substantially increased.
The objective of this research study was to develop a Compendium of world-wide best practice in the energy efficient design and operation of water industry assets.
The compendium records energy efficiency best practice across a matrix of the water cycle from abstraction, treatment and distribution to sewerage, treatment and disposal. The processes start with conservation and leakage, focus on pumping and aeration, and include sludge treatment. Relevant renewable energy applications are covered to reduce the net energy demand.
Best practices are established through Fact Sheets and illustrated by Case Studies from across the world linked to headings in the matrix. Conclusions on savings and technology are drawn and suggestions are made for future research and development.
The compendium allows easy assimilation of best practice to increase energy efficiency in the water industry for senior management, engineering, operation and maintenance personnel.
