Free Relay Replacement

(G99) NATIONAL GRID FUNDING FOR ACCELERATED LOSS OF MAINS PROTECTION SCHEME!


Here at G99 training we can not only train you to become a test engineer, but we also undertake to get your system registered on the ENA/Nation Grid scheme, so you don’t have to pay for the upgrade of your SSEG which you will have to do if you want to stay connected under the new engineering recommendations.

I hope we have enough information on these pages to help you understand what will be required in the next couple of Years.

LOSS OF MAINS PROTECTION

Generation owners are required by the Distribution Code to install loss of mains (LoM) protection at distributed generation sites.

This is to ensure that, following a fault that isolates sections of the distribution system to which they are connected from the rest of the electricity system, distributed generation does not form an autonomous power island with the remaining local demand.

Other faults elsewhere on the GB electricity system should not result in the operation of LoM protection. The two most commons forms of LoM protection are rate of change of frequency (RoCoF) relays and vector shift (VS) relays.

Other forms of LoM protection, eg direct intertripping, are also available. It was identified that RoCoF relays and VS relays could inadvertently operate and trip distributed generation following events that do not result in islanding.

This resulting loss of generation could cause a significant system disturbance and a widespread loss of supply. The cost of managing such risk, incurred by NGESO and funded by BSUoS charge payers, in 2018 exceeded £100m.

To aid you we have also put a link here, which you can use to view the full report from the Distribution Network Owners and National Grid ESO.

What we can offer you is, clients who make early applications will both benefit from reduced outages and will receive an upgrade payment from National Grid for each relay that is excepted onto the scheme.

Payment will be in the order of £1k to £1.5k for relays that can have settings changed or between £2.5k and £4k if a relay must be replaced with a new unit.

To apply for the support funding, an application must be submitted to the DNO who will then assess the application against various criteria, we can do this application for you.

At the time of the application the details of the relays, make, type and settings will have to be provided along with other information.

If approved by the respective DNO, then the work can take place by competent contractors such as Dave Pallas who is registered on the accepted contractors list, and once the evidence of the change has been provided, then payments will be made to the Generator by National Grid.

The change can be done before agreement is reached with the DNO, but evidence must be provided that the relay change was needed (i.e. It was not already set to use RoCoF) and it has been completed.

We can manage the entire process for you from making the application, site investigation to determine the type of change that is needed and then undertake the works for you.

Please use any of our contact details to get in touch.
