UK-first trial of ground-mounted energy saving transformers commences

Northern Powergrid is to become the UK’s first distribution network operator (DNO) to trial super low loss ground-mounted Amorphous transformers (AMTs).

Announced on 6 December, the trial of the AMTs will form part of its wider Losses Discretionary Reward programme, set to be submitted to Ofgem in March 2020. The transformers can reduce core losses by up to 90% and could lead to annual losses savings of up to 2GWh for DNOs, if rolled out across its operational area.

Over the next 12 months, Northern Powergrid will conduct sound testing, thermal imaging and power quality testing to monitor the performance of the AMTs. The transformers are being installed at strategically selected sites for the trial, including Bishop Auckland and two sites in Hull. The outcomes will be shared as a UK case study for DNOs, commercial and industrial users.

Aisha Ahmad, Smart Grid Development Engineer at Northern Powergrid, said: “For too long, losses have been seen as an unavoidable reality of network operation, but new technology means we can now tackle the problem head on. Trials like this will help build our understanding of losses, support decarbonisation and make Northern Powergrid’s network as efficient and reliable as possible.”
