INVERTER REPOWERING ACROSS 4 SITES
Case Study 8
Situation/Challenge
Inverter stations on solar farms convert direct current (DC) electricity generated by solar panels into alternating current (AC) for use in the grid. However, over time the efficiency of these inverter stations begins to deteriorate due to aging hardware, outdated technology, and the lack of spare parts. With one client, there was a decision to invest in a complete revamp of their solar inverter stations across multiple sites.
BGE Solution
Across 4 sites in Somerset, Devon and Dorset aggregating 24 MW, BGE engineers replaced a total of 14 inverter stations. This work involved deconstructing old Emerson inverter stations and replacing each one of them with a new SMA inverter station. The old inverter stations were stripped for spare parts and recycled. Innovatively, the inverter platforms were adapted for the installation of the new systems. The jobs were completed with the installations of new Power Plant Controllers and new meters.
Outcome
The commissioning and energisation of the 14 new inverters were achieved successfully within the project deadlines. The results were enhanced efficiency, downtime minimised, and the lifespan of the sites extended. The client was pleased with the quality of BGE’s service and has since commissioned repowering on two more sites, involving replacing 11 inverter stations.
