Nova Scotia's capital city is hoping to supply close to 40% of its electricity needs with wind power by 2008 and save millions of dollars in the process. Halifax Regional Municipality (HRM) is agreeing with two wind developers to buy 22-25 GWh a year for 20 years. HRM staff estimate buying wind will save the municipality between C$8.3 million and C$28 million over the life of the contracts, depending on how quickly electricity costs continue to rise in the province's largely fossil fuel based system. The forecast assumes a 2.5% annual increase to achieve the $8.3 million in savings. HRM issued a request for proposals last summer and selected Barrington Wind Energy, based in Halifax, and Toronto's Ventus Energy as its suppliers.
