    Introduction of the CEZ Group

    • CEZ Group is an integrated electricity company with operations in a number of countries in Central and Southeastern Europe and Turkey, with its headquarters in the Czech Republic (Installed capacity 15 620 MW). Employs almost 27 000 people.

    • CEZ Group currently operates:

    – 2 nuclear power plants (4 290 MW)

    – 15 coal-fired power plants (5 527 MW)

    – CCGT power plant 840 MW

    – 35 hydropower plants, including 3 pumped storage plants

    in the Czech Republic.

    – 2 locations with wind power plants (Fantanele 600MW)

    – 2 coal-fired power plants in Poland (678 MW)

    – CCGT power plant 904 MW in Turkey

    • CEZ is the largest electricity producer in the Czech Republic

    – producing nearly 61 TWh a year (approximately 50% in NPP)

    The PI System at CEZ: CUTD Project

    Purpose:

    1. Unification of data base technology & data. Consolidating multiple technologies at multiple sites.

    2. Operations & maintenance savings

    3. Increased availability of operations data

    • The project included: • Replacement of existing storage

    • Migration of all necessary data from the original storage

    • Switching applications to new storage

    Efficiency Monitoring: Transformation

    Past Present

    No online data - difficult to monitor efficiency in real time

    The real heat rate after month energy balance

    Partial non - fulfillment hidden in monthly averages

    Incomprehensible information for service personnel

    Real-time, Online monitoring

    Immediate information on the device status

    Clear information for service personnel (maintenance,

    operators)

    Real time decision making

    COMPANY and GOAL

    Company

    Logo

    Leveraging the PI System to improve

    Efficiency & Water Consumption

    CEZ Group operates more than 20 thermal power plants and wanted to reduce loss in variable caused by the late response of service personnel to degraded parameters.

    • No real-time efficiency

    monitoring

    • Incomprehensible information

    for service personnel

    • No information about water

    consumption

    • Creating the efficiency monitoring center

    • Creating the water monitoring screen

    • Real-time efficiency

    monitoring

    • Informed service staff

    • Real-time water

    consumption monitoring

    • Using tools PI Vision and Asset

    Framework (AF]

    • Savings in variable costs in the

    order of millions CZK/year • Late response of service personnel

    to degraded parameters
