True added value project delivery

As part of the electricity infrastructure, Dunamis designed and delivered a 132kV electricity connection for UK Power Networks (UKPN), which owns and maintains the electricity network in London and the South East, and an adjacent 132/33kV substation for Statera Energy, and all associated structural, civil and electrical works.

Utilising its experience and expertise in the delivery of large-scale battery storage infrastructure, Dunamis was able to achieve accelerated timescales, which included a six month construction phase, through the use of its in-house design division and in-house construction teams via sister company, Maintech Power.

“We’re delighted to have successfully completed this complex and innovative project with Dunamis. We will continue to engage with high quality contractors such as Dunamis for the build-out of our pipeline of storage and flexible generation projects in the UK."
