This Preliminary Market Engagement (UK2) notice is being issued to inform the market that Yorkshire Water Services Limited is undertaking early engagement with suppliers to support the development of the sourcing strategy for a Direct Procurement for Customers (DPC) Programme Advisory Framework. Yorkshire Water is progressing a pipeline of major infrastructure projects for delivery using the Direct Procurement for Customers (DPC) delivery model. Under DPC, a competitively appointed provider designs, builds, finances and potentially operates major infrastructure assets under long-term contractual arrangements. DPC projects are subject to regulatory oversight by Ofwat, including staged regulatory submissions demonstrating strategic case, procurement readiness, and value for customers before contracts can be awarded. Yorkshire Water is therefore exploring the establishment of a multi-disciplinary professional services framework and/or strategic partnerships to support the development of bankable DPC projects capable of progressing through regulatory approvals and competitive procurement. The framework may provide support across several disciplines, including: • Technical advisory - engineering, design, environmental assessment, ecology, planning and technical assurance • Commercial advisory - development of business cases aligned with the HM Treasury Five Case Model, procurement strategy, market engagement, commercial structuring, risk allocation, payment mechanisms and incentivisation structures • Legal advisory - development of robust contractual arrangements for major infrastructure concessions, building on previous DPC and infrastructure projects, including specialist support in planning and infrastructure law • Programme assurance - independent assurance of submissions and programme governance to ensure regulatory compliance and readiness for Ofwat/RAPID assessments and associated approval processes The information gathered through this engagement will help shape the proposed scope, structure, commercial model and procurement approach for the framework. This exercise is for information-gathering purposes only and does not constitute a call for competition. Participation in this engagement will not provide any advantage or disadvantage in any subsequent procurement process. Suppliers interested in contributing to this market engagement are invited to express their interest in accordance with the instructions set out in this notice

Yorkshire Water (YW) and Kelda are seeking to engage the market to discuss their planned deployment of new on-shore wind turbines. Work done to date indicates deployments of 1-3 turbines at each location, with 7 sites under consideration initially plus 2 re-powering sites. As YW and Kelda look to expand this programme, they anticipate a small scale wind development programme in addition. The deployments would be on YW operational land and would directly power the adjacent operational site, offsetting grid purchased power. Early turbine identification, based on site constraints and available wind yields, suggests Kelda are looking to initially procure in the 500 kW - 3.45 MW range. This will result in a variance of turbine sizes from hub heights between 40 - 80 meters, and tip heights up to the region of, but not limited to, 117 metres. Later phases of wind development will be in the sub 250 kW range. The purpose of this notice is to open discussion with turbine manufacturers / suppliers to understand; - Equipment / turbines availability; - Indicative lead times for supply; - Indicative pricing, both capex and opex; - Indicative commercial terms; and - After sales maintenance provision. - Transport management - Installation These are non-conclusive and are likely to change as development progresses. YW and Kelda anticipate the award of the procurement in 3 bandings: 1. 1MW A procurement partner may look to cover all of these bandings or just 1. YW and Kelda are open to both new and refurbished turbines via direct purchases from OEMs, broker facilitated procurement and framework agreements.

Yorkshire Water (YW) and Kelda are seeking to engage the market to discuss their planned deployment of new on-shore wind turbines - specifically regarding bankable wind data without the requirement for 12 month Met Mast or LiDAR campaigns. Work done to date indicates deployments of 1-3 turbines at each location, with 7 sites under consideration initially plus 2 repowering sites. As YW and Kelda look to expand this programme, they anticipate a small scale wind development programme in addition. The deployments would be on YW operational land and would directly power the adjacent operational site, offsetting grid purchased power. The purpose of this notice is to open discussion with wind data analysts, modellers and providers. We would like to work with wind data specialists with a proven track record of securing wind turbine project finance having used modelled wind data, processed into a bankable format, without a 12 month LiDAR or Met Mast campaign. Data must include: - Annual Average(mean) wind speed (at hub height) - Once in 50 years 3 seconds maximum wind gust - Weibull Shape factor k - Wind shear index IEC alpha - Characteristic turbulence at 15m/s, or the full turbulence graph - Wind farm output at P50/P90 levels (gross and net yield) The following can be provided: - Wind turbine locations - Wind turbines hub heights - Wind turbine makes and models - Any other relevant data YW and Kelda are looking to partner with a single data provider who can provide bankable wind data which will be used for accurate financial modelling and securing project finance.
