PBA Consulting Ltd

PBA has built a reputation for successfully supplying high voltage services and solutions focused on the asset management of high voltage equipment. Since 2009, our hands-on specialist service has been progressively blended with a growing consultancy service based on our learnings around the asset management of transformers, circuit breakers, and SF6 stewardship. We have now taken our next evolutionary step by founding PBA Consulting Ltd which will focus on supplying high voltage engineering consultancy services and will complement the high voltage specialist services offered by PBA.

Our consultancy services in HV asset management have been augmented to now include system planning studies, including connection studies for hydro, thermal, solar, or wind generators, and HVDC Links.We advise on electricity market systems, and investigate major incidents. PBA’s contracting services and consulting services are able to leverage off each other to offer a mix of high voltage specialist knowledge that is rare in the power industry.
