WPD launches new pilot to manage demand, save customers money

Western Power Distribution (WPD) has announced the launch of a domestic flex pilot scheme to help customers save money and manage demand on the network.

Launched on 30 October, Sustain-H is the first flexibility services project from WPD that is specifically designed for domestic customers. It will ask providers to drop to – or below – a pre-agreed level at pre-agreed times. They will then need to hold that usage for a four-hour window. Customers delivering within these targeted four hour windows will each be able to earn around £10 a year for homes with electric vehicle chargepoints and up to £60 a year for a home with a “full suite” of flexibility technologies, such as heat pumps and batteries.

Sustain-H is being procured in Constraint Management Zones within the Midlands, the South West and Wales. It was designed by WPD, Everoze and SGC during the spring.

Eight providers have already signed up to offer the service to their customers, which is four times the number that the trial organisers had been hoping for. They include Ecotricity, EDF, Octopus Energy, Kaluza, SMS, Stemy Energy, ev.energy and myenergi. Five are set to go live in November, with another three coming online in March 2021.
