Improvements in identifying revenue theft have also been recorded. In 2007 teams of revenue protection personnel found some 290,000 customers who were stealing energy, and Light reported that 72 GWh had been recovered. The utility says that the extra revenue arising from these activities will allow it to invest even more in revenue protection methods in the years to come. These methods will include communication programs with customers and the implementation of new technologies to identify energy theft more efficiently, including smart meters. Regular inspections of customers’ premises will be carried out, and obsolete meters will be replaced.
