HBS to power Affinity Water’s operations towards net-zero

We are delighted to announce that water supplier Affinity Water has sought the renewable energy expertise of HBS New Energies to help develop and deliver its solar PV programme.

Working closely with Affinity Water’s Estates Team, HBS New Energies have been managing all aspects of DNO, survey and detailed design of the Walton Solar PV Farm and have started construction on site this week. It is the first project to be delivered under phase 1 of an exciting roll-out of renewables.

Due to be completed in early 2022, the 553 kWp ground-mounted solar array will feed directly into the Walton Water Treatment Works (WTW). The solar installation will generate 535,706 kWh of clean, green electricity per year to help sustainably power the Affinity Water production site.

Graham Deans, Head of Estates and Facilities Management at Affinity Water said: We’re pleased to take this important first step to develop our renewables portfolio as we continue to play our part and realise our Plan for Net Zero operational emissions by 2030 and improving energy efficiency. In working with HBS New Energies we have the expertise on board to deliver and I am looking forward to progressing the next phases of our plan in the months and years ahead.

Tackling climate change and reaching Net Zero is one of the biggest challenges the world faces, and our customers and stakeholders are looking to us to see what we are doing to achieve it.”

Key project facts for Walton WTW Solar Array

  • The Walton Water Treatment Works (WTW) uses approximately 5,547,346 kilowatt-hours of energy per year to supply clean water to hundreds of thousands of Affinity Water customers. 
  • The ground-mounted solar installation being built by HBS New Energies will provide up to 10% of Walton’s energy consumption.
  • That’s enough electricity to power 142 homes every year. Based on the average UK household consumes 3,760 kWh per year.
  • The solar energy produced by the 1216 solar panels will also save around 168.71 tonnes of carbon annually.
  • The solar PV array at Walton WTW will offset the equivalent annual carbon emissions of 73 family cars (based on 12,000 miles annually). 

Earlier this year Affinity Water set out its route map to net-zero to achieve zero-carbon operational emissions by 2030. This commitment will be met by developing a renewable generation portfolio of solar and wind across their estate. Other sustainable projects include purchasing green grid-supplied electricity; optimising energy efficiency and demand reduction on production sites, electrifying their fleet of vehicles and sequestration initiatives. 

As a major energy user, Affinity Water hopes that by 2030 it generates 10% of its total energy usage from on-site renewable energy generation assets like solar, wind or hydrogen and thereby reducing reliance on the National Grid. 

James Bull, Managing Director at HBS New Energies said: I am delighted that Affinity Water has chosen HBS New Energies as a strategic solar partner to develop their renewable generation portfolio and support them on their journey to achieving net-zero operational emissions by 2030.  

We look forward to delivering the first phase of this exciting solar programme. It is a crucial first step to helping cut Affinity Water’s carbon footprint and reducing its reliance on grid-supplied electricity.

John Toms, Head of Commercial at HBS New Energies, added: We are looking forward to helping Affinity Water kickstart the roll-out of renewables across their estate. Using our extensive experience and technical expertise within the water utility sector, we are perfectly positioned to support Affinity Water and build high-performance solar installations.  

When complete, the on-site renewable source at Walton will contribute to lowering carbon emissions and strengthen Affinity Water’s ability to future-proof operations against volatile energy costs.

The partnership with Affinity Water is the latest to be forged by HBS New Energies and continues an ongoing strategy to increase renewable generation and reduce emissions within the water industry and help accelerate the journey to carbon neutrality by 2030.

HBS New Energies appointment builds on its impressive track record of supporting solar programmes for some of the UK’s leading water service providers including Anglian Water, Welsh Water, Thames Water and United Utilities.
