Overview

Solar Partnership Market Engagement. We are issuing a UK2 Preliminary Market Engagement Notice to formally invite market responses.

Our prospectus outlines our objectives and current thinking — and sets out four high-level questions for which we are seeking written responses to through our e-tendering portal. Following an initial review, we will invite selected organisations to structured follow-up conversations.

Sessions will last approximately 60 minutes and will follow a consistent format across all respondents. These sessions are intended to better understand and explore the feedback already submitted as part of the pre-market engagement to the 4 questions included.

Submission

Written responses should be submitted by May 20th 2026.

Additional details

There is no requirement to prepare additional material beyond your original responses. Discussions will be conducted in a structured and consistent manner across all suppliers, using the four questions as the agenda.

We may ask follow-up questions to clarify or explore your responses in more detail. We are in listening and understanding mode and will not be sharing additional information beyond that already published in the Prospectus.

Any insights that may influence the future procurement approach will be documented and, where appropriate, shared in a transparent manner with all potential bidders. To ensure transparency and an audit trail, notes will be taken.

Participation in a follow-up conversation does not confer any advantage in any subsequent procurement process. We are holding the discussions to help WMCA better understand the market, it doesn't mean a supplier has been shortlisted, it's not mandatory and it wont provide an advantage or disadvantage in any future procurement process. Please use the following link to view the PME and respond - https://procontract.due-north.com/Advert?advertId=4944a9e... **** The estimated value represents the estimated total gross revenue receivable by the supplier from tenants, grants, grid exports and any other revenue over the potential duration of supplying services to tenants under the contract ****
