Customer Change Team Leader


NGN is seeking to identify a means of ensuring that the impacted properties’ AQs can be managed so as not to increase the amount of energy requiring to be purchased by the shippers at the affected meter points.

NGN (and Cadent) is working in partnership on the HyDeploy2 Project to blend up to 20% by volume (6% by energy) hydrogen into isolated pilot areas on each of their networks. This Innovation Project is entering into Phase 2 which will involve two trials on small sections of live gas network(s)

The Project Team has selected discrete area within the NGN network, which can be isolated, on which to undertake the HyDeploy2 Live Pilot and the commercial impacts of the hydrogen blend will need to be managed through the CDSP Central Systems.

The consumers at the properties impacted will be engaged directly by a dedicated NGN team – there are approximately 670 largely domestic properties involved. The first live pilot is scheduled to commence in Quarter 4, 2020 and will run for a period of 10 months.

The use of the hydrogen blend will result in a lower calorific value being passed through the consumers meter compared to natural gas; the exact calorific value being received by the isolated trial area will be monitored throughout the trial.


This Change is in scope of November 2020 Release, information about this Release can be found here.
