Biogas upgrade and offtake, Knostrop and Blackburn Meadows

• Value: £130M

Yorkshire Water Services Limited ("YWS") is seeking to enter agreements for the sale of all biogas produced through its anaerobic digestion ("AD") processes at its Knostrop wastewater treatment works in Leeds. 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 the site. YWS 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 hosts a large AD facility, historically producing 14-15 million Normal Cubic Meters ("Nm3") of biogas annually, 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. Note, biogas volumes may increase or decrease due to operational performance, environmental schemes being undertaken and external factors. Annual production figures are not guaranteed. The required capital works is anticipated 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. YWS therefore anticipates that the appointed partner will enter into sub-contracting agreements as needed to provide a complete DBFOM solution for YWS. 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. To express your interest please email Kenneth.gaffney@yorkshirewater.co.uk with full contact details including phone, email and postal address for the individual who will be the primary contact for future correspondence. Bidders will be required to register with the Ariba Sourcing platform to participate in this requirement. All bidders will be required to agree and sign a Bidder Agreement as well as an Ariba Engagement Policy, which will be available via the Ariba Sourcing platform once registered. This is a mandatory requirement before receipt of any further documentation. YWS is not bound to (and makes no representation or other commitment that it will) award any contract (nor enter into any other arrangement) as a result of the procurement process to which this notice relates, and reserves the right (subject to compliance with its legal obligations) to discontinue or change the procurement process at any time. YWS will not be liable for any costs, expenditure, work or effort incurred by any person in responding to this notice or proceeding with or participating in the procurement process, including if the procurement process is discontinued or changed by YWS. Additional information: Please note it is anticipated that the contract can generate c£130m revenue over the 15-year term. This revenue estimate is based on utilising all biogas for renewable transport fuel production, and assumes upgraded biogas sales realise £0.30/kg and RTFCs (generated from renewable fuel production) are sold at £0.30 per RTFC. Indexation is assumed to be 2% p.a. Bidders should note that this is an estimated value only and they are required to make their own assumptions regarding all relevant prices and costs.

YWS 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"). Blackburn Meadows wastewater treatment works hosts a large AD facility, historically producing 6-7 million ("Nm3") of biogas annually, which is presently used in combined heat and power ("CHP") engines.
