Good to know
Your questions, answered
Will joining affect my backup reserve?+
A flexibility provider should work within the limits and reserve settings agreed for your system. Check the specific scheme terms before joining.
Do all batteries and chargers qualify?+
No. Eligibility depends on the manufacturer, model, connectivity, tariff and the integrations supported by each provider.
Can I use optimisation and a VPP together?+
Sometimes, but services can conflict if more than one platform is trying to control the same asset. Confirm compatibility before connecting both.
Is income guaranteed?+
No. Returns depend on asset availability, market conditions, programme rules and how often your system can participate.
