What is RCOA?

Retail Competition and Open Access (RCOA) allows qualified electricity end-users (known as Contestable Customers or CCs) to choose their own electricity supplier instead of staying with the Distribution Utility (DU) in the franchise area where the CCs are located.

Through this Power of Choice, CCs have a direct influence on how they can effectively manage their electricity costs by successfully entering into Retail Supply Contacts (RSCs) with Retail Electricity Suppliers (RES).

CCs who have entered into RSCs have enjoyed transparent prices, flexible contract terms that meet their specific requirements, and other value-added services.
