Yorkshire Water is seeking to enter agreements for the sale of all biogas produced through anaerobic digestion (AD) at its Knostrop wastewater treatment works, in Leeds, and Blackburn Meadows wastewater treatment works in Sheffield.

The contract is being tendered in two separate Lots - the water company is looking to enter agreements for the sale of all biogas produced through its anaerobic digestion (AD) processes at both wastewater treatment works.
The agreements will be on a design, build, finance, operate and maintain (DBFOM) basis, and will require the development of a biogas upgrading facility on leased land within each site.
Yorkshire Water anticipates that the appointed partner can obtain greatest value from using the upgraded biogas for biomethane-based road transport fuel sales and the generation of renewable transport fuel certificates (RTFCs).
Knostrop wastewater treatment works and Blackburn Meadows wastewater treatment works both host a large AD facility, historically producing 14-15 million Normal Cubic Meters (Nm3) and 6-7 million (Nm3) of biogas respectively on an annual basis, which is presently used in combined heat and power (CHP) engines.
Following installation, all biogas produced will instead be directed to the biogas upgrading facility at each site.
The required capital works are expected to include installation of biogas pre-treatment, an upgrading facilities and gas export infrastructure at the site.
The subsequent operational period will be managed by the appointed partner and is anticipated to include operation and maintenance of the biogas upgrading and export facilities, with responsibility for all activity downstream.
The launch of the procurement process has a Spring 2022 target completion date. Yorkshire Water intention is for the successful commissioning and operation of both facilities will be achieved as soon as possible, but no later than 1 April 2024.
Initial contract term for both Lots is 15 years, with a potential extension option of a further 5 years.
Anticipated revenue generation over the initial period is an estimated £130 million at Knostrop and £60 million at Blackburn Meadows.
The revenue estimates are based on utilising all biogas for renewable transport fuel production.
The procurement process will launch in Autumn 2021, with a Spring 2022 target completion date. YWS seeks that successful commissioning and operation of the biogas upgrading facility will be achieved as soon as possible, but no later than 1 April 2024.
