Operation and Maintenance

We offer operation and maintenance services for energy production plants as well as industrial or municipal energy consumers. Pöyry has its own modern equipment for conducting these services.

Pöyry's main operation and maintenance services include:

  • Emission measurement services as a test laboratory (T062) accredited by FINAS (Finnish Accreditation Service) according to the SFS-EN ISO/IEC 17025:2005 standard covering the following exhaust and flue gas compounds: particulates, oxygen, oxides of nitrogen and sulphur, carbon monoxide and carbon dioxide, hydrogen chloride and hydrogen fluoride, hydrocarbons volumetric flow and composition of gas
  • Calibration and comparison measurements (QAL-2 and AST) of continuous measurement systems in industry and energy production plants according to the SFS-EN 14181:2004 standard, using accredited reference methods
  • Measurement of following emissions: odorous sulphur compounds (both TRS and separate compounds), PCDDs/PCDFs, PCBs, chlorophenoles and PAHs, ammonia chlorine and chlorine dioxide, heavy metals, fine particles (PM1.0, PM2.5 and PM10), condensible particulate matter
  • Performance measurements (boiler plants, steam turbines, gas turbines, cooling towers, desulphurisation units, NOx removal systems and electrostatic precipitators), wind power plants, regenerative thermal and catalytic combustion plants, solvent recovery plants
  • Condition monitoring, revision and operational tests for assessing the performance development of processes or individual components and need for overhaul and maintenance
  • Noise measurements and modelling (3D modelling of noise transmission to the area for environmental permitting needs)
  • Provision of technical advisors for annual overhauls and operation and maintenance planning

Extensive wind power measurements during development phase covering also arctic climatic conditions:

  • Implementation of meteorological measurements by means of mast measurements and supplementary soundings
  • Development of measurement systems

Wind power measurements in operational phase:

  • Commissioning, i.e. power curve measurements according to the IEC 61400-12 standard
  • operation and maintenance consulting
  • Energy efficiency assessment and benchmarking for power plants and process industry
