The Globe and Mail reports in its Saturday edition that TransAlta has scrapped a wind farm it had planned for southwestern Alberta and put three other projects on hold, blaming restrictions that the province's UPC government has imposed on renewable energy and uncertainty over coming market changes. The Globe's Jeffrey Jones writes that TransAlta has cancelled development of its 300-megawatt Riplinger wind farm, which had been planned for Cardston county near the Rocky Mountain foothills. The project, which would have comprised 47 turbines, is located in a newly restricted 35-kilometre exclusion zone near a protected area, chief executive officer John Kousinioris said. "So that is a project that we will not be proceeding with," Mr. Kousinioris told a conference call to discuss the company's first-quarter results. The Riplinger wind farm had been scheduled to start up in 2027. Meanwhile, the Calgary power generator is putting three other projects on hold until it has more clarity on the future of Alberta's electricity market redesign. After a seven-month moratorium on new renewable-energy projects in the province, Premier Danielle Smith imposed new restrictions on wind and solar energy that came into force in March.
