Centrica, owner of British Gas, has signed a seven-year $400m (£247) cloud outsourcing deal with HP.
The move is part of an outsourcing shake-up which will see HP and Fujitsu provide desktop and datacentre services, while the previous supplier of these services, T-Systems, will focus on SAP services in the cloud and smart grid technology.
Dave Bickerton, CIO of Centrica, says the deal will help provide flexibility, cost-savings and reduce the company's carbon footprint.
"Centrica is striving to improve our ability to respond to market changes to supply gas and electricity to homes and businesses more efficiently," he added.
HP will provide Centrica's migration to a private cloud- and utility-based computing through its two UK datacentres. Datacentre support will come from HP Best Shore global delivery centres in India, Malaysia and the Philippines.
"The utility industry around the world is making great strides using technology to support an 'instant-on' enterprise that gives businesses and consumers more control over their energy use and utilities more options in how they deliver energy," said Mike Nefkens, senior vice-president at HP Enterprise Services.
