1. Are you interested in bidding for this opportunity? [Yes/No]

2. Do you have a single project that is eligible as per the parameters set out in the table [Yes/No] If ‘No’, what is your biggest single eligible project that you would be interested in bidding for a CPPA opportunity? What volume would the project be capable of meeting?

3. Do you have any concerns with any of TfL’s parameters? We are particularly interested if you have concerns with the delivery window, volume, or the contract length, but welcome all feedback.

4. If you don’t have an eligible project or are not interested, why not? E.g. the delivery window is not suitable for you, public sector procurement processes, current market conditions, etc. Please give as much detail as possible.

5. If TfL’s PPA procurements (now or in the future) were to run simultaneously with the Government’s Contract for Difference auctions, would this deter you from taking part in TfL’s PPA procurements? Please give rationale for your response.
