Walters Power UK

Walters Power entered the UK market in 2009 with an 8MW plant in Yorkshire. The plant is the first of an expected series of small power plants in the United Kingdom to be developed by Walters Power UK. As the UK transitions from high-carbon (primarily coal) generation plants, Walters Power UK plans to develop a number of power plants to address anticipated peak power shortages. "We've traded in UK-based equipment for years and own a significant inventory based in the UK, so we're able to respond quickly to local energy needs," said Walters Power UK President David Walters.
