Field is a London energy company founded in 2021 that develops, builds and operates grid-scale battery storage. Its sites store surplus renewable generation and release it when demand rises, supported by in-house trading and optimisation software. The company is building a portfolio of storage assets across Britain and continental Europe.
Backed by Local Globe

Field has entered its next phase of growth. In June, the UK energy regulator, Ofgem, selected 16 long-duration energy storage projects to progress to delivery. Field were awarded 5 of these. Collectively, in MWh terms, our projects are approximately 3 times the capacity of all battery energy storage installed in the UK to date. We currently have 4 projects totalling over 1GWh of energy storage in construction in GB with lots more delivery to do.

Your Mission

As Lead Grid Connection Engineer (Delivery) you will be responsible for leading grid compliance deliverables on some of the world’s longest duration BESS projects from pre-construction right through to FON (Final Operational Notification)

The role requires hands-on, pro-active management of your projects and key stakeholders (e.g. BoP contractors, BESS Suppliers, Consultants, TO’s and NESO). You therefore need to be highly engaged, resilient, execution-focused and detail-oriented. You’ll need to be passionate about power systems engineering, well-versed in UK grid code, and work well as part of a multi-disciplinary project team.

You will report into our Head of Delivery (Michael) and work closely with in-house experts across Engineering, QHSE, Procurement, Legal and Development.

If you’ve managed the end-to-end compliance process on transmission-connected renewable projects then we’d love to hear from you, particularly if you have experience on projects in north Scotland.
