In a remarkable feat of engineering and adaptability, one of the UK's largest "private wire behind the meter" solar farms was successfully designed and installed, boasting a 20 MW capacity with 37,440 PV panels. The project, initially conceived as a 9.5 MW rooftop system, evolved into a ground-mounted solution due to structural concerns. This transition exemplified the team's problem-solving prowess as they navigated environmental challenges, including wildlife relocation and archaeological considerations. The complex DNO application process, involving G99 and G100 protocols, was skillfully managed, securing a 13.6 MW grid export allowance. Now generating 20% of the manufacturing plant's power requirements, this solar farm significantly contributes to Nissan's ambitious carbon neutrality goal for 2050 and supports their strategy for all-electric vehicles by the early 2030s. This project stands as a testament to innovative sustainable energy solutions in the face of
