EPUKI is the UK division of EPH, operating a portfolio of power generation assets across the UK and Ireland since 2015. The company owns and operates fossil fuel and renewable generation facilities, alongside flexible generation assets that provide balancing and grid services. Named assets in the portfolio include Ballylumford, Corby, Kilroot, Tynagh, Langage, Lynemouth, and South Humber Bank.
The company's technical footprint spans generation (both baseload merchant and peaking operations), energy trading, grid balancing services, and power station construction and development. Central functions - engineering, finance, trading, and operations - are distributed across offices in Leeds, London, and Dublin. EPUKI is part of a larger group operating over 70 companies across Europe, with capital investment plans exceeding £2bn.
The operation sits at an inflection point in UK and Ireland energy markets: managing legacy fossil fuel infrastructure while expanding flexible generation capabilities to support grid stability as the region transitions toward Net Zero. That dual mandate creates technical complexity around asset optimization, trading logistics, and regulatory compliance across two separate grid jurisdictions. The company emphasizes flat structures and fast decision-making in response to market volatility and shifting energy policy.
