Project description 

Fortum’s world-class operation and maintenance (O&M) concept and extensive experience as an owner and operator of biomass-fired power plants was one of the most important reasons for why Fortum eNext was chosen as operation and maintenance partner at the new power plant. When starting its commercial operation, the 299 MW Tees renewable energy plant in the UK will be the largest and most efficient dedicated biomass-fired power plant in the world. The plant will be using wood pellets and chips from United States and Europe as the fuel.

Under long-term operation and maintenance (O&M) contract, Fortum is responsible for the full-scope operation and maintenance activities at the plant, including mobilisation, staffing, operation and maintenance, management of a steam turbine with a long-term service agreement as well as the implementation of Fortum's O&M digital tools CMMS and TOPi®. The full-scope operation and maintenance means that Fortum eNext takes the overall responsibility for power plant operation and maintenance activities including operational and service management as well as for the personnel.
