Request
I am researching solar photovoltaic (PV) development and wish to make the following request under the Freedom of Information Act.
Q1 On land and building assets that are owned or controlled
* by the authority, how much solar PV capacity in kilowatt peak (kWp) has been installed? (*"controlled" means where the authority has management control of a site's facilities and utilities, such as under a long-term lease)
I would like the response for this to be separated into four categories:
* Solar PV capacity owned by the authority:
* Solar PV capacity owned by a community group:
* Solar PV capacity owned by another party, that is not a community group, where a power purchase agreement (PPA) exists to supply the authority:
* Any other solar PV capacity owned by another party:
* If an exact figure for installed solar PV in kWp cannot be obtained, please make an estimate of a minimum value that is known with confidence.
For example, “estimated – at least 100kWp”.
Q2 This question asks for information about procurement of solar PV goods and services in the past three years, where a contract has been awarded between 1 January 2023 and the date of this request.
Could you supply me with the following information please: I have also put Q2 into an Excel template (attached to this email).
Please use this to return to me, if possible. Please complete these columns for each procurement activity (add more if necessary) No.

Response
Q1. On land and building assets that are owned or controlled* by the authority, how much solar PV capacity in kilowatt peak (kWp) has been installed? (*"controlled" means where the authority has management control of a site's facilities and utilities, such as under a long-term lease)
I would like the response for this to be separated into four categories: Solar PV capacity owned by the authority: Estimated 270 kWp
Solar PV capacity owned by a community group: 0.0 kWp
Solar PV capacity owned by another party, that is not a community group, where a power purchase agreement (PPA) exists to supply the authority: 0.0 kWp
Any other solar PV capacity owned by another party: 0.0 kWp
Q2. Please see Excel spreadsheet attached.
