Greg Dilger of Renatus chats with Paddy Finn, the joint founder and CEO of Limerick-based VIOTAS about his business as well as a range of topical sustainable energy issues. An academic entrepreneur if ever there was one, Paddy developed an interest in demand response and smart grid technology during his time, as both undergraduate and postgraduate, at the University of Limerick, and led to him co-founding VIOTAS (formerly Electricity Exchange) with Duncan O’Toole in 2013.
