Working with Statera Energy, a developer, owner and operator of flexible electricity generation infrastructure, Dunamis undertook the design, installation and commissioning of the 132/33kV infrastructure that connects the Pelham battery storage project, located near Bishop’s Stortford in Hertfordshire, to the electricity network.

Our solution

  • 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 Fulcrum Group company Maintech Power.  

Benefits delivered

  • Completed from design to commissioning in just ten months, the facility has a peak output of 49.99MW and has the potential to provide enough power for over 13,000 UK homes at any moment in time.
  • Maintech Power was awarded the ongoing electrical maintenance contract for the facility.


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.
