This article discusses how aging wind farms are retooling older turbines. Because of that, jobs and a thriving industry are growing up around the ‘repowering’ of existing wind farms, as technology upgrades increase their renewable energy production.
Old wind farms that have towered over the same fields for more than a decade may be generating more power now than ever before.
As America’s biggest wind farms age, their owners are starting to “repower” them with more efficient turbines, new electronics and longer, lighter blades that can sweep more wind with each rotation. The result is a thriving new industry, new jobs and more renewable energy.
New blades and technology updates have completely “revitalized” two Leeward Energy wind farms near Sweetwater, Texas, saving the company money and allowing the farm to generate more energy, said Leeward CEO Greg Wolf.
