Net Zero, Energy and Transport Committee

Subordinate Legislation

Meeting date: 7 November 2023

Patrick Harvie

That is correct. That is what generates a revenue stream for the network, which is what makes it an attractive proposition for investors. The experience with heat networks in this country鈥攁nd, I think, in Denmark, where they are used the most extensively of any European country鈥攊s that they tend to be affordable and attractive for that reason, compared with individual consumption of gas or other fuels.

Heat networks are particularly viable and effective when they have a range of different heat consumers鈥攏ot all domestic but some commercial, some industrial, and large public buildings, for example鈥攁nd a range of heat sources. Some networks will have a heavy reliance on a single heat source or small number of heat sources. Existing networks will be under a duty to bring forward a plan to decarbonise if they have a polluting heat source.

However, over time, as we see the extensive development of heat networks, we are likely to see that viability become an incentive for any operator to diversify its heat sources. That might be by using banks of heat pumps. In the Glasgow area, it might be using the River Clyde as a heat source, as Queen鈥檚 Quay does. It could also include industrial sources of heat, such as waste heat and other options. The diversification of heat producers and heat consumers is one of the things that will make the networks more viable for the long term.

It will come from a range of sources.

Local authorities will produce their LHEES and provide them to Government. I think that they are all to be provided to the committee as well. They will be made public.

Those are the existing targets under the act. The 2035 target is for what happens beyond that.

As we set out in the consultation, the three proposed targets were based on not only the information from the first assessment report, which looked at where heat network zones will be, but a range of scenarios about the viability of heat networks鈥攁 high or low scenario might mean more or fewer heat networks respectively in those areas that have been found to be suitable鈥攁nd assumptions about a connection rate of 50 per cent.

As we go forward, we will have to address some of the issues around demand assurance so that those developing and investing in heat networks have confidence that there will be consumers connecting to them. However, we made that connection rate assumption for the short period ahead, before the demand assurance measures are in place.

Therefore, from those three factors, we derived proposals for targets of 6TWh and 7TWh and the other stretch target of 12.5TWh. Although a case can be made for any of those targets, it was felt pretty clearly that the target of 7TWh was stretching in terms of achieving significant growth in the sector but also achievable.

It will depend on the specific settings in each area. That is why LHEES are being taken forward at the local level.

If the committee has not had the chance to learn about the heat network in Shetland, for example, I think that that would be instructive. It has been in operation for 25 years, and the company is now looking to expand and extend it, including to potential customers who are not right in the town centre.

There are some energy losses that come from extensive heat networks, but the experience of Denmark is that you can have them over a very wide area, and they do not just have value in the inner core of a city, so we would like to ensure that as many parts of Scotland as can benefit from heat networks do so.

Of course, in less densely populated areas, other approaches to decarbonisation鈥攊ncluding individual heat pumps and other technologies鈥攚ill be, and already are, extremely successful.

That question is probably best directed at colleagues who work on the waste side. There are many reasons why there is an environmental desire to move away from burning our waste鈥攖o put it simply鈥攅ven with modern technology. As Monica Lennon鈥檚 question hinted at, it requires a continual feed of waste material going in, and it is not consistent with a circular economy approach.

The approach with regard to heat networks is that, where an existing facility has waste heat that is going into the air and is not benefiting anyone, we might as well plug that into a heat network and get some value and use out of it.
