Bristol’s Heat Network

Today’s guest blog is from Councillor Nicola Beech, Cabinet Member for Climate, Ecology, Energy, and Waste, and Labour Councillor for St George Central

To play our part in the fight against climate change, Bristol has committed to becoming a carbon neutral city by the year 2030. The expansion of Bristol’s Heat Network to new communities across Bristol is one key ingredient in securing Bristol’s energy future and providing businesses and homes with heat and energy form low carbon sources.

Heating and hot water currently account for 40% of energy-related carbon dioxide emissions worldwide, and 40% of Bristol’s emissions come from heating our homes and workspaces, so it is vital that we continue to invest in technology like this to support our transition to net zero.

What’s Bristol’s Heat Network?

Heat networks are a network of underground pipes that deliver affordable, low-carbon heat and energy to homes and businesses across the city. Bristol’s Heat Network is divided into different sections that cover areas across the city, with each section powered by a local energy centre. Heat networks are not new technology and are commonplace across Europe, with Copenhagen topping the charts with its heat network supplying around 98% of the city’s heat demand. Heat networks are less common in the UK and Bristol really does lead the way here.

Our existing heat network now supplies over 1,000 properties with low-carbon heat with pipe spanning over 8km underground. The neat part of heat networks is that they can draw their heat from many different sources – from the river to sewers to underground geothermal. So as our city continues to transition to 2030 and other heat sources become available, our heat network can live on.

But timing is everything and our cabinet paper brings forward our investment into Bedminster Green where 2,000 new homes are being built. By taking this decision, we are ensuring that we minimise disruption during the installation of the underground pipes and low carbon energy centres and have the energy solution in place ready to serve new developments as they are built.

What’s next for Bristol’s Heat Network?

The approved Bedminster section of the network will use heat extracted from waste-water in our sewer system to provide homes with warmth and warm water. We are living our waste nothing values by recycling Bristol’s hot shower water to heat homes elsewhere.

We are also continuing with the construction of a new Water Source Heat Pump in Castle Park, a renewable technology that will create heat from water in the floating harbour and the largest in the country.

As we see global shocks in gas prices forcing consumer bills up, I am really proud to be part of an administration which is creating the energy infrastructure Bristol needs, putting us in control of our energy future and taking big leaps on our journey to 2030.
