IT giant Hewlett-Packard will be powering its entire global information technology requirements via wind power, under a 12-year power purchase agreement signed last week with SunEdison.

The agreement will see HP purchasing 112 megawatts of wind power to supply the company’s 1.5 million square feet (140,0000 square metres) of data centre operations located in Texas.

HP said the agreement would avoid the emission of more than 340,000 tonnes of carbon dioxide annually, and would enable it to reach its 2020 operational greenhouse gas emissions reduction target of a 20 per cent reduction on 2010 levels by the end of the 2015 financial year. The locally generated power is equivalent to the annual electricity use of 42,600 homes.

“This agreement represents the latest step we are taking on HP’s journey to reduce our carbon footprint across our entire value chain, while creating a stronger, more resilient company and a sustainable world,” Gabi Zedlmayer, HP’s vice president and chief progress officer, corporate affairs, said.

This is the first utility-scale renewable energy purchase by HP, and is part of a wider push to develop a sustainable cloud.

The agreement has enabled SunEdison to begin construction on a new 300MW wind farm in Texas that is expected to create more than 400 jobs during the construction phase and up to 15 permanent jobs during the operational phase. The company said the project would also provide local economic benefits including land lease payments and property tax revenues.

“Wind generated electricity represents a good business opportunity for Texas and for HP,” Paul Gaynor, executive vice president, Americas and EMEA at SunEdison said.

“By powering their data centres with renewable energy, HP is taking an important step toward a clean energy future while lowering their operating costs. At the same time, HP’s commitment allows us to build this project which creates valuable local jobs and ensures Texan electricity customers get cost-effective energy.”

Both HP and SunEdison are among the founding members of the Business Renewables Center, a non-profit organisation created last year to facilitate large-scale corporate purchases of renewable energy.
