So far over £165 million of Heat Networks Investment Project (HNIP) funding has been awarded to date.
The most recent recipient is Kent County Council securing £2,478,000 to support the development of a low carbon heat network in Maidstone.
Local authorities across the UK have announced ambitious targets in an effort to not only encourage local businesses and households to act but also to accelerate national action to fight climate change and meet the 2050 net zero target.
Kent County Council has adopted a leadership position by committing to reducing carbon emissions for its own services and buildings to net zero by 2030 and for the whole county by 2050.
To understand how different decarbonisation scenarios could achieve net zero, Kent County Council used a pioneering methodology from Laser Energy (a business unit within Commercial Services Kent Ltd, a company wholly owned by KCC) to identify the most suitable approach for the county which consisted of 3 primary ways of reducing emissions; investing in renewable energy generation, shifting to electric vehicles and energy rationalisation.
The approach identified strategic actions, many of which are already underway but also included the establishment of a heat network in Maidstone.
The decision to invest in a heat network scheme in Maidstone supports the net zero aspiration; creating a low carbon, deliverable demonstrator project which will encourage local stakeholders to recognise heat networks as a viable opportunity to decarbonise heat in the town.
The opportunity for heat networks within Maidstone and the wider region has not yet been fully exploited and it is hoped this pioneering project will encourage their wider use.
The Maidstone Heat Network has potential to connect over 24GWh of heat demand as it extends North and South into the town centre.
A water source heat pump and gas boiler system supported by a local solar farm will enable the network to transition to net-zero carbon operation.
This combination means that heat generated from the Heat Pump is essentially zero carbon. The network has been designed with an oversized thermal store to balance periods of low carbon heat generation and heat demand.
At full capacity, it is expected that the heat pump will delivery over half of the network’s heat demand.
Moreover, the network could connect to additional low carbon heat sources in the future, further reducing emissions.
This local authority scheme provides an excellent example of how heat networks can not only deliver low carbon heat to our homes and buildings today, but also support future growth and expansion.
With annual carbon savings of around 1,300 tonnes per year over the first 15 years of operation, this network will play a key role in progressing the work already carried out by the council to reduce carbon emissions to net zero.
Kent County Council have already successfully reduced carbon emissions by 50% between 2010 and 2020.
Ken Hunnisett, Triple Point Heat Networks Investment Management said:
“Local authorities have a unique combination of skills, powers, local knowledge and relationships with key stakeholders. This allows them to drive forward projects such as the Maidstone heat network scheme to support the achievement of local and national climate change targets, whilst maximising the benefits to their communities. We are proud to support these efforts and look forward to working with other local authorities as they work towards net zero.”
To date HNIP has awarded over £165 million to 24 heat networks across England and Wales. In total, 128km of pipe will be built out across the successful HNIP schemes connecting over 52,000 homes and almost 230 non-residential buildings to low carbon, affordable heat. The estimated carbon savings are substantial and further decarbonisation and expansion opportunities exist for all the projects supported by HNIP.
About the scheme:
Kent County Council: £400,000 grant for commercialisation and £2,077,864 grant for construction
Kent County Council has a strong track record in delivering low carbon and zero carbon projects.
The Maidstone district heating network presents one of the strategic energy infrastructure developments in the region which will support the council’s net zero aspirations.
The council opted for a low carbon solution which utilises a water source heat pump combined with low carbon electrical power generation. The scheme has been developed as an enabler network for further expansion into the local area, and to increase its proportion of heat from low carbon sources.
It is expected that the network will provide affordable, low carbon heat to 110 homes and 5 non-residential properties.
