3. The market opportunity: scale and technology pipeline

Provide a granular breakdown of the project’s technical requirements

ALPHA

Section objective

To provide a granular breakdown of the project’s technical requirements. By categorising properties into 'technology pathways,' the council enables the supply chain to see exactly which products and skills will be in demand and they can identify more precisely where they can contribute.

The value to stakeholders

  • Manufacturers: can forecast the volume of units (eg, 4,000 ASHPs vs. 2,000 shared loop systems) needed in their production cycle and forecast investment into wider supply chain enhancements such as marketing, show homes and sales teams.

  • Installers: can identify if they have the right certifications (eg, MCS for individual units vs. specialist drilling/groundwork skills for shared loops) existing fossil-fuel installers are able to make decisions about joining the renewables workforce based on the future direction for their local market.

  • Investors/lenders: The 'total pipeline' figure (~7,500) provides the scale needed to justify project finance or specialised delivery models.

What to include in this section

  • Technology segmentation: don't just list a total number of homes. Break them down by the likely heating solution (individual, networked, or communal). To help do this, complete the table in the text box below with the estimation for your area using Nesta’s heat planning tool. Briefly explaining why certain technologies were chosen for certain areas (eg, "dense areas with no outdoor space") helps contractors understand the site constraints they will face.

  • The 'anchor' mix: Explicitly mention non-domestic buildings (schools, colleges, retail). These are 'anchor loads' that often make the commercial case for heat networks more attractive.

  • Visual data: Include a technology suitability map (as shown in the example below). A map turns a table of numbers into a geographic work plan that a local business can visualise.

Heat planning tool

Nesta is currently developing a clean heat planning tool. This tool will automatically identify the most suitable technological approach for groups of similar neighbouring properties in Great Britain.

The tool is based on open-source data and is free for Local Government.

The video below shows the core features of the tool. It enables the identification of opportunity areas across all groups of low-carbon heating technologies for your local authority, filter opportunity areas according to your priorities and drill down into specific clusters to explore the underlying data such as tenure, property types, information about properties off-gas, presence of listed buildings and more.  With one click, you can also export a data-backed pipeline of opportunities to inform your local plan.

3. The market opportunity: Scale and technology pipeline

Our analysis confirms that a mix of technologies would best meet the diverse needs of AREA's housing stock, including KEY ANCHOR LOADS. This creates a varied and significant pipeline of work. The plan is built around three core technology pathways, with a clear initial rough breakdown of the market size for each, as shown in Table 1.

Table 1.  Initial breakdown of potential technology pathways

Technology pathway

Description

Estimated properties(includes a mix of individual houses, flats and larger commercial and educational buildings)

Individual heat sources

Standalone systems per property, such as air source heat pumps, ground source heat pumps, air to air heat pumps or other electrified heating. 
Most suitable for: Properties with large garden/outdoor space and properties already off the gas grid.

NUMBERNUMBER
Tip: a range (e.g., 2,000 – 2,500) works best here to show there is flexibility and potential overlap.

Networked heat sources

Individual ground source heat pumps connected via a shared loop, known as shared ground loops or networked ground source heat pumps.
Most suitable for: dense areas with little to no private outdoor space and properties that are in listed buildings, or in a conservation area (due to the lack of changes to the built environment).

NUMBERNUMBER

Communal heat sources

A single large heat source (e.g. communal ASHP or GSHP) serving an individual building and multiple dwellings, or a small number of nearby buildings via a communal heat network. Networked GSHP could also be suitable.
Most suitable for: Dense properties with little or no private outdoor space, with an existing communal heating system, room for a plant room or an outdoor communal heating source, or those near waste heat sources.

In summary, this section establishes the technical roadmap for AREA, moving from broad ambition to defined heat pathways for different areas withinAREA. The analysis confirms that a mix of technologies is essential to meet the diverse needs of the AREA’s properties. This data-led approach provides the certainty you need to forecast demand, prepare stock, and allocate personnel

Recommendation

At this stage it is recommended to engage the supply chain and other local stakeholders.

It is recommended to form an advisory group that ensure interests are represented and opportunities identified through the combination of local and professional knowledge. This also invites other to be included within the plan, and it’s onward development and delivery.

For more guidance on the kind of roles that may form an advisory group see our guidance on forming a team.
