Hinkley Point C Nuclear Power Station (HPC) is a two-unit, 3,200 MWe EPR nuclear power station under construction in Somerset, England. Hinkley Point C will provide zerocarbon electricity and help secure a diverse and balanced energy supply for the United Kingdom. Arabelle Solutions, under a contract with NNB GenCo, designs and supplies two conventional power islands for Hinkley Point C nuclear power plant. The turbine halls will contain the Arabelle turbine, the largest and most powerful steam turbine to be in operation, along with other critical equipment.

In September 2021, ENKA signed a contract with Arabelle Services UK Ltd. for the prefabrication and erection of piping systems for the conventional power islands of 2 units, where each unit will be producing 1,600 MW power. The scope of works to be carried out under ENKA’s responsibility may be summarized as installation of high pressure (HP) piping and its supports, supply, prefabrication and installation of intermediate pressure (IP) and low pressure (LP) piping, prefabrication and assembly of high-density polyethylene (HDPE) and glass reinforced plastic (GRP) piping as well as their supports and installation and assembly of fire protection equipment and piping systems. ENKA also provides commissioning support and material management services to Arabelle Services.

In July 2024, ENKA entered into an additional contract with Arabelle Services Ltd. for the verification of the design, procurement of materials and installation of thermal insulation for both piping and equipment in the turbine hall.
