The CER licences competing electricity suppliers to serve customers needs and sets a range of licence conditions that are designed to protect customers and promote competition. A full list of licensed suppliers and their contact details can be found in the section "Electricity Supply Licences".
The CER has overseen the gradual liberalisation of the electricity supply market which culminated in full market opening in February 2005. The regulatory framework created the right environment for competition to develop and since then competition has increased in the business and domestic markets. In 2010, the CER published its Roadmap to Deregulation, which set out the milestones for the end of price regulation. All business markets were deregulated from 1st October 2010. From April 2011, the domestic market will be deregulated and all suppliers will be free to set their own tariffs.
The retail market is also supported by ESB Networks, who provide meter reading and data management services for all suppliers and customers.
This section of the CER website outlines the regulatory arrangements currently in place to support competition and ensure that customers are protected and further the aim of a truly competitive retail electricity market offering real value and quality service to customers.
