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.


Our specialist technical advice is led by our Technical Directors

Dr Ranil de Silva and John Pringle

Ranil de Silva has worked on the technical analysis of power systems across several countries, including grid planning, insulation coordination, HVDC systems, electricity markets, and incident investigation.

John Pringle’s expertise in the installation and maintenance of transformers and circuit breakers has given him insights into the issues faced by the owners of ageing HV plant.

PBA Consulting also taps into the skills and experience of the wider PBA group and affiliated engineering resources. This allows us to bring in subject matter experts as required.

PBA Consulting’s Vision is to be a trusted advisor to our customers, with a thorough understanding of our customer interests, and providing independent and objective advice based on our specialist experience in the high voltage power industry.
