Advantage NRG secures additional £6.7m of contracted works

Hercules plc (AIM: HERC), a leading UK infrastructure and construction services group, is pleased to announce its specialist power and energy subsidiary, Advantage NRG, has secured new works with a combined contract value of c.£6.7m across the National Grid network in England. Advantage NRG specialises in the supply of linesmen for the construction and maintenance of overhead electrical transmission lines.

The new works run from March to October 2026. At peak delivery, the contracts will require up to 79 skilled operatives, demonstrating Advantage NRG's expanding operational scale and technical capability.

These works show there is growing demand for the delivery of linesman teams as electricity network operators accelerate investment in resilience and capacity.

This is in addition to the Group's update in February, when Hercules announced £6.5m worth of contracts for Advantage NRG, from January to December 2026.

Hercules believes Advantage NRG is well-placed to benefit from the UK's major upgrade of its electrical infrastructure to meet rising energy needs. National Grid proposals include £58 billion of investment focused on extending and modernising the country's transmission and distribution networks to deliver sustainable and reliable power across the UK.

Brusk Korkmaz, CEO of Hercules, said: "Advantage NRG is going from strength to strength thanks to the increasing demand for its specialist teams from electricity network operators across the UK. The power and energy sector is a key growth driver for Hercules and these new contract wins highlight the Group's position as a trusted partner to the network operators."
