Generation Business

TOA OIL's Mizue Power Station generates electrical power under contract from Showa Shell Sekiyu K.K.. A part of generated powers is also supplied on a wholesale basis to TEPCO Energy Partner, Inc.

  • 1Receiving of fuel for generation
    Fuel for power generation is supplied directly from our adjacent Keihin Refinery by pipeline. Linking power stations directly to refineries enables us to reduce our stock of storage tanks for generating fuel and use heat more effectively, assuring highly efficient operations.
     
  • 2-1Generation: Boiler turbines
    In boiler-turbine power generation, fuel is burned in boilers to boil water, generating high-temperature, high-pressure steam.
    This steam drives turbines, whose rotational energy is captured by generators as electrical power. Byproduct gases from the oil refining process and oil residues are used as fuel.
     
  • 2-2Generation: Gas turbines
    In this arrangement, instead of steam, high-temperature, high-pressure gas generated from the burning of fuel expands to drive turbines, and this rotational energy is captured by generators as electrical power.
    Byproduct gases from the oil refining process are used as generating fuel.
     
  • 3Environmental measures
    The exhaust gases are treated using an array of environmental equipment comprising desulfurizers, denitrators and electrostatic precipitators. These systems scrub the exhaust of sulfur oxides (SOx), nitrogen oxides (NOx) and dust, which are causes of environmental pollution.
     
  • 4Power transmission
    TOA Oil supplies the power it generates to Showa Shell Sekiyu K.K. and TEPCO Energy Partner, Inc., which in turn supply power to customers.
