Sembcorp Utilities UK and UK Power Reserve have been combined together and rebranded as Sembcorp Energy UK.
Singapore-based parent company Sembcorp Industries bought UK Power Reserve for £216 million in 2018.
Sembcorp Utilities UK provides energy and water services to occupants of the Wilton International industrial park in Teesside, while UK Power Reserve (UKPR) operates a fleet of peaking plants and batteries across the UK.
Nomi Ahmad, head of Sembcorp Energy UK, said: “The unification represents the next step in our plan to give Sembcorp a firm foothold in the flexible distributed energy business, which is a new growth niche.
“In line with the integrated business, Sembcorp Energy UK will be rolling out its merchant and retail strategy with three new key appointments.”
Cathy McClay, the former head of future markets at National Grid Electricity System Operator, has been appointed as head of strategy. She previously held positions at National Grid, EDF Energy and British Energy.
Günther Puffer will oversee the company’s wholesale market operations as head of merchant. He was previously value delivery director at Origami Energy and before that worked at Statkraft and RWE.
And Tim Foster, formerly the head of UK operations for ElectroRoute, will take on the post of head of origination. His other prior employers include Statkraft, Smartest Energy and British Energy.
As part of the merger, Sam Wither will step down as the managing director of UKPR in November.
“Sam’s keen market insights and valuable contributions have been vital to the business,” added Nomi.
“He played a leading role in the integration of UKPR and Sembcorp, as well as growing the business. We wish him the very best in his new adventures.”
Sembcorp Industries chief executive Neil McGregor said: “As the sector moves towards decarbonisation and the shared goal of achieving net zero, we are confident that Sembcorp can play an integral part in meeting the nation’s energy needs. We are passionate about supporting our industrial customer base in the North East and the overall energy markets.
“We are also committed to adapting our business model by building our presence through incremental investment in UK capabilities and sustainable energy solutions. We regard the UK as a key long-term market and are setting our sights beyond current uncertainties, towards a better, more sustainable future for all.”
