Noventa Energy Acquires Innovative Heat From Waste Water Assets From Scottish Water Horizons

Noventa Energy (Noventa), a leading provider of decarbonised heating and cooling solutions, has acquired three innovative heat from waste water assets from Scottish Water Horizons. 

These assets, located in Glasgow, Stirling and Campbeltown, and the first of their kind in the UK, will be partially repowered to benefit from Noventa’s proprietary, world-leading technology to reduce emissions and expand heat generation capacity.  

The strategic transaction will also enable Scottish Water Horizons, a commercial subsidiary of Scottish Water and a leader in sustainable energy, to release capital to carry out further investment in renewable technologies. 

The three heat from waste water schemes currently provide heating to district heat networks owned by Stirling Council and Clyde Gateway, as well as a leisure centre owned by Argyll & Bute Council. The energy centres also provide power to wastewater treatment plants owned by Scottish Water in Stirling and Glasgow. The services are provided under long-term heat and power agreements and are delivered through combined heat and power and wastewater energy transfer systems.

Together, these schemes have the potential to generate 33GWh of heat and 15GWh of power annually, the equivalent of heating and powering almost 5,000 and 1,000 average homes respectively across the UK. Under Noventa’s ownership, they will continue to contribute towards Scotland’s national targets for reducing greenhouse gas emissions and strengthen energy resilience in these communities.

Following the acquisition, Noventa will invest in upgrading the assets with its proprietary systems. These will significantly increase the utilisation of heat from waste water to provide additional renewable heating capacity for customers. 

“This sale enables us to accelerate the development of renewable energy technologies, such as heat from waste water projects, further supporting Scotland’s energy transition.

“We remain deeply committed to Scotland’s low carbon heat market, and our partnership with Noventa ensures these assets will continue to grow, contributing to Scotland's net-zero goals by providing reliable, low-carbon heating solutions.

Managing Director, Scottish Water Horizons

Scottish Water Horizons will continue to work closely with Noventa on the development of future projects, enabling both companies to meet the growing demand for sustainable heating solutions across Scotland. Paul Kerr, Managing Director of Scottish Water Horizons, said:

“This sale enables us to accelerate the development of renewable energy technologies, such as heat from waste water projects, further supporting Scotland’s energy transition.

“We remain deeply committed to Scotland’s low carbon heat market, and our partnership with Noventa ensures these assets will continue to grow, contributing to Scotland's net-zero goals by providing reliable, low-carbon heating solutions.

"This aligns with our strategy of incubating and divesting at the right time, maximising impact, and reinvesting in projects that protect our environment for future generations.”

The acquisition was funded by Ancala, a leading infrastructure manager. Ancala invested in Noventa in 2023 and is working closely with the management team to pursue its international growth plans and accelerate delivery of Noventa’s significant pipeline of waste water energy projects.
