Flexible Power aims to help business customers in Western Power Distribution's licence areas     make the most of their energy flexibility. This is done  by providing access to  Constraint Managed Zones (CMZ) services  which are split into three    products:  Secure, Dynamic    & Restore.

The initial process for selecting zones has now been completed.   The available zones are highlighted below and go live on 28/10/2018.
