British Solar Renewables creates smart energy systems for a net zero carbon future. British Solar Renewables develops (BSR Energy), builds (BSR EPC), and maintains (BSR O&M) utility‑scale solar, wind and storage projects in the UK and internationally. Having developed and built in excess of 700 MWp, BSR is a major contributor to the UK Renewable Energy Sector.
Head of OT
The fundamental objective of the Head of OT is to manage the OT team in designing, deploying, and supporting the communication and monitoring systems on new and existing distributed energy projects. As new PV and battery sites increasingly rely on their communication networks for operation, BSR needs to ensure that new designs meet the current requirements for performance and cybersecurity, and that older designs are maintained and upgraded in line with current industry practices. The Head of OT will also be available to provide advice and assistance for reactive issues which need additional skills or experience and will participate in an on‑call rota for out‑of‑hours remote support along with the other members of the comms team.
