Deval is the main electricity distributor in Valle d’Aosta, offering its services to over 130,000 consumers in 69 of the 74 municipalities in Valle d’Aosta and using more than 4000 km of medium- and low-voltage power lines. The high quality of its service, guaranteed by a well-organised 24/7 on-call system, is also the result of the continuous technological upgrading activities it performs on both distribution lines and metering units. In fact, electronic meters are in place for over 95% of supply contracts meaning that these can be remotely managed in full, readings and contractual changes included.
