HNTAS: Draft Substation technical specifications for new build heat networks
Draft Heat Network Technical Assurance Scheme (HNTAS) regulatory technical requirements to help heat network developers, contractors and operators demonstrate compliance.
Applies to England, Scotland and Wales
Documents
Details
These technical specifications for heat network substations detail the draft requirements and technical obligations to be fulfilled as part of the upcoming Heat Network Technical Assurance Scheme (HNTAS).
A substation is a connection between distribution networks which contains an exchange of thermal energy (for example, via plate heat exchangers) together with other necessary equipment.
The specifications include the:
- technical requirements to be met
- performance monitoring requirements to be met
- key failures to be avoided
- evidence requirements to be provided to demonstrate conformity with HNTAS
They are for use by:
- heat network developers
- heat network designers
- heat network operators
- heat network equipment suppliers
- organisations within the heat network supply chain
These technical specifications correspond to the draft HNTAS assessment procedures for heat network substations.
Next steps
We will be requesting feedback on the information in these documents shortly. We will run a change management process in parallel with the HNTAS technical standards consultation which will launch shortly.
We will make final versions of these documents available before the scheme starts.
