In 2016, the heat sector finally recognised the importance of performance data. Helped by companies like Guru, heat network operators began to obtain energy performance data from their networks.

The data sent shockwaves through the industry as many realised that their networks are not performing anything like what was promised, largely due to shortcomings in design and commissioning.

Using this information, the operators of these poorly performing networks could finally attach precise numbers to their long-held suspicions: that losses are high, that heat costs too much and that service can be unreliable. Of course, customers on bad networks already knew this from their own experiences of high bills, cooking corridors and intermittent heating and hot water.

As this awakening gathers pace, a key trend for 2017 will be the move towards quantified performance. Armed with clear requirements, clients will be more specific about what they want, and use measurement and verification to ensure they get it. ESCOs, having had their fingers burnt, will no longer be content to sample the performance on a limited number of dwellings before adopting a new network. Instead they will use performance data to verify that 100% of equipment in homes has been properly commissioned. In short, networks won’t be allowed to go into operation until they work as intended.

This change in approach will have huge implications for the industry.

What... is the efficiency of your district heat network?

What… is the efficiency of your district heat network?

In order for district heating (DH) to fulfil its potential and deliver wide-scale decarbonisation of heat in the UK, it must demonstrate three things:

  • Efficiency: DH networks must transport heat energy from source to customer with low losses.
  • Low carbon emissions: using DH must result in demonstrably lower emission by connecting customers to sources of low-carbon heat.
  • Value for customers:  heat customers must have the means to ensure they’re getting value for their money.

So how are we doing? And what progress have we made in meeting these three challenges so far?

The chancellor has allocated £300m to heat networks. What happens next matters – a lot.

When I started working in the low carbon sector in the early noughties, it felt like we had all the time in the world. You could tinker about with gizmos like earth pipes and building-mounted wind turbines and feel like you were doing good. Hockey stick carbon graphs seemed a bit abstract and rarely got people’s blood pumping.

The intervening years have flashed past. Now in 2016, Governments, businesses and communities around the world have woken up to the scale of the threat from climate change. Pressure to act is mounting.

Randy Cambell knows: sometimes halfway is worse than nothing at all.

Randy Cambell knows: sometimes halfway is worse than nothing at all.

The Heat Network Code of Practice is likely to become intertwined with building regs. In particular, heat networks that comply with the Code could be treated more favourably under SAP.

But as I highlighted in the last post, we’ve got a problem: there’s currently no such thing as a Code-compliant heat network. For SAP to reference the Code, some form of Code compliance regime will be required.

DECC has said it wants to keep any such regime light touch, which seems reasonable. But, as I hope to describe in this post, a light touch regime could greatly damage the heat market. In other words, the wrong compliance regime would be worse than no regime at all.

Heat networks finished 2015 on a high. In a year in which the Government hammered almost every other part of the low carbon sector, heat networks not only escaped harm, they unexpectedly received a £300m boost in November’s Comprehensive Spending Review. And there may even be further support if projects can secure a share of new innovation funding at DECC.

So you might expect this market to rapidly pick up speed. But funding is only part of the picture. Even more important is policy, because just like a species is shaped by its ecosystem, heat networks are shaped by their policy landscape.

This landscape can be defined by three key features: the CIBSE Code of Practice, the Heat Trust rules and SAP. Influential as they may be, these three features aren’t set in stone. Far from it. All three will undergo major changes in 2016, with so much potential to shake up the market that it’s tough to predict how projects will look (commercially, technically, legally) a year from now.

What might these upcoming changes mean for projects, practitioners and operators?
