Operational data from onsite energy systems (like heat networks) is extremely hard to come by. Very few people manage to get hold of it, and those who have it rarely share.

What are the typical loads in dwellings? What are the network losses? Do customers all demand heating at the same time or are demand events spread out?

Who knows? Engineers don’t stick around and find out how their designs work in real life; ESCOs hold their cards close to their chests; and many landlords fail to extract or make use of their own data.

This dearth of data has hamstrung the industry at a time when it should be racing ahead. It’s one of the biggest reasons why, when it comes to energy performance, we’re just not getting better fast enough.

In late 2014, when DECC put out a call for proposals to improve heat networks, we saw a chance to unlock some of these data silos and accelerate development of the heat market.

gilliganAndskipperIn a shock move, last autumn the chancellor allocated £300m to heat networks to be spent over the next 5 years. This funding presents a golden opportunity, but there’s a real danger it will be spent delivering more of what we’ve already got.

Largely driven by planning policy, the district heat market is currently made up of tens of thousands of small networks, each on its own little island with few connections to bigger sources of low carbon heat. Poorly delivered and rarely checked, many of these networks suffer from dismal efficiency.

As I pointed out in my last post, the industry is busy grappling with just getting the basics right: reducing heat losses from networks and protecting end customers. But time is short: the UK’s looming carbon targets mean that even at this early stage in market development, we have to stay focused on the endgame of CO2 reduction.

So how should DECC spend the money? Here are my suggestions:
