What is the DTS?

The Data Transfer Service (DTS) is the founding function ElectraLink was created to procure. Incorporating the technological Data Transfer Network as well as customer service and governance principles, the DTS facilitates the movement of critical information between energy suppliers, Distribution Network Operators (DNOs), metering agents and other market participants.

This creates a diverse, innovative, adaptable marketplace where market participants can perform their roles well, maximise efficiency, and drive better outcomes for energy users in households and businesses.
