2.  In 1998 Queensland Electricity customers exceeding 40GWH were given the opportunity to enter the National Electricity Market (NEM). This meant these customers could investigate opportunities in obtaining better energy charges as an alternative to Franchise Tariff Rates as gazetted by the Queensland Government.  Tariff equalisation policy operates in Queensland. This means similar customers will pay the same Notified Prices whether they are in Brisbane or Mt Isa.  Notified Prices are controlled and Gazetted by QLD Government. These are generally reviewed annually. Network Charges and Energy Charges are bundled together to form a Tariff Rate.  Queensland customers do however have the option to enter the NEM and take advantage of any cheaper energy costs if available in the NEM or stay on Notified Prices. Since the market opening in Qld all customers now have the opportunity to choose Contestability or stay on Safety Net Notified Prices.

3.  Electricity markets have deregulated  Functions of generation, distribution and retail have been separated  Electricity is now a commodity bought and sold like any other  Retailer may change each year with contracts but the Network provider remains the same.  Franchise or notified priced customer’s new gazetted tariff rates are published on the 1 st July every year. This is a Government determination.

5.  EEQL is the Host Retailer for all EECL Notified Prices Customers still with EECL.  EEQL is still responsible for energy sales and associated services (Retail Franchise Tariffs, Green Credits, Green energy etc) to customers Connected to EECL.  As per Section 92 of the Electricity Regulations eligible customers may elect to stay on the safety net Notified Price structure or choose to become a Contestable customer. Except for those Small Customers consuming below 100MWh's/year, once a site is Contestable the site cannot elect to return to safety net Notified Price rates (See Regulations for details).  For Customers who have chosen to take up a Market Contract and go Contestable (Small Customers consuming less than 100MWh's/year) who then choose to revert back to a Non Market Contract they must remain with their current Retailer who are obliged to offer equivalent rates similar to Notified Price rates.  Should an eligible customer elect to become a Contestable Customer the customer will need to ensure Rules compliant metering is installed and an Electricity Retail Sales Contract is in place. This can be arranged through the Customer’s Retailer of Choice.
