Developments must connect to heat networks in earmarked zones

Proposed developments within or next to identified heat network zones (HNZs) in Scotland should only get permission if they can connect to one of the existing communal heating systems, according to the Scottish government’s new planning blueprint.

The final version of the Holyrood government’s fourth National Planning Framework (NPF), which was published on Tuesday (9 November), says Scottish councils should take into account HNZs when drawing up their local development plans (LDPs).

It says that developments within or adjacent to identified HNZs will only be supported in these local plans where they are designed and constructed to connect to the existing heat network.

Where a heat network is planned but not yet built, proposals will only be supported if cost-effective connection is allowed for at a later date

The NPF also confirms the Scottish government’s backing for onshore wind projects, which was outlined in the draft framework published last year.

The final version states that LDPs should identify opportunities for all forms of renewable and low-carbon energy technologies, including onshore wind farms, enabling grid infrastructure, batteries, pumped hydro storage and solar arrays.

It says that once an area has been identified for wind farms, it should be suitable for this use “in perpetuity”.

However the new planning blueprint, which has been drawn up to replace the third NPF that dates back to 2014, maintains the existing embargo on development of wind farms in national parks and National Scenic Areas.

It says that when considering renewable energy generation development, planners should give “considerable weight” to the contribution they make to greenhouse gas reduction targets.

The NPF says renewable energy development should not be constrained by grid capacity and consideration should be given to underground connections where possible.

The document also identifies hubs for renewable energy development in the Orkney, Hebrides and Shetland Islands.

The Royal Town Planning Institute Scotland hailed the publication of the finalised NPF 4 as a “significant milestone” in the country’s ambitions to tackle climate change.

The framework will now be discussed and voted on by the Scottish Parliament.
