Under a seven-year contract, Enron Energy Services will supply electricity and gas to all Sainsbury's UK offices and depots and to 450 stores.
Enron will also manage a £15 million energy efficiency investment programme, encompassing refrigeration, heating, lighting and ventilation.
Sainsbury's intends that most of the work will contribute towards its existing aim of upgrading all its supermarkets to the standard of the best by 2004. Energy use was identified as one of four corporate environmental priorities (ENDS Report 318, pp 25-27 ).
Enron is hailing the Sainsbury's deal as "the first of its type in the UK to combine commodity supply with a project-driven energy reduction programme."
