Stuart Harris, Head of Energy and Carbon Operations, BT Technology, Service & Operations

“We have been very pleased with the quality and workmanship from the team at Powerstar – the energy savings have been higher than forecast and we are expecting to run a phase 2.

Powerstar has been very flexible in scoping, design and working around our operational units to ensure full services were maintained. I have no hesitation in recommending Voltage Optimisation from Powerstar and we are pleased with the full service Powerstar provided.”
