National Grid ESO is offering nine-year contracts for reactive power services in the Mersey region.
Reactive power helps keep voltage levels stable, with providers either generating or absorbing reactive power. The Mersey tender is for absorption.
The tender is in two stages, a technical submission on 13 Dec and a commercial submission on 21 Feb 2020.
Delivery is required from 1 April 2022 and the tender is open to providers connected at both distribution and transmission level, including including those that are not yet connected.
Providers are allowed to stack additional services – but they must be available 24/7 to deliver contracted reactive power services if instructed to do so.
The minimum size for participating in the tender is 15MVAr. Sub-units as part of an aggregated portfolio must be at least 5MVAr.
The contracts are based on availability prices only, there is no utilisation fee.
