The Electricity Enquiry Service (EES) is also known as the Electricity Central Online Enquiry Service (ECOES).
The EES is a service funded by electricity suppliers and distributors and governed under the Retail Energy Code (REC).
EES was designed to assist suppliers in the customer switching process by allowing the triangulation of data; it is also used to provide benefit to REC Parties and non-REC Parties (such as PCWs).
