Nova Scotia Power has agreed to buy another 2 MW of wind power from Renewable Energy Services Ltd (RESL). The developer, based in Lower Sackville, already has 4.4 MW of wind power either operating or close to being completed in the province under an earlier contract with the utility. "We have fulfilled our original agreement with Nova Scotia Power, but are fortunate to have three more turbines available to us," says RESL chairman Dale Robertson. The turbines, which include an Enercon E48 unit and two Turbowinds 600 kW machines, are expected to be operating by the end of the year, although the company had yet to finalise sites when the contract was announced at the end of July. "We've got an inventory of sites and we are just picking the best ones now," says Robertson. RESL won its original contract in a Nova Scotia Power solicitation for projects less than 2 MW in size. Its installations are all so-called exploratory turbines that allow the company to assess the wind resource at various sites in anticipation of potential future expansion. When that expansion might occur, says Robertson, will depend on the province opening up the market to allow companies like RESL to sell directly to retail customers, or on Nova Scotia Power deciding to buy more wind. Meantime, the company is shifting its focus to Alberta where it is looking at developing a site near Pincher Creek in 2007.
