          Bacviz Kecskemet (Hungary)

          Service solution to reduce energy consumption and the electricity bill in a pumping station

          Reference: Water 15% energy savings, ROI in less than 3 years

           

          I. CUSTOMER ENVIRONMENT / PROJECT CONTEXT

           

          Customer profile:

          • Bacviz is the operation company in charge of providing drinking water to the town and region of Kecskemet. It represents a population of 120 000 inhabitants.
           

          Customer objective and constraints:

          • In Hungary the electrical utility providing electrical energy to the water operation company has a price policy based on a fixed subscription. When the water utility has peak demands over the subscription value some penalties are applied. The water utility wants to avoid this cost.
          • More generally a clear understanding of the consumption of the different process steps is required to optimise the process. On average electricity bill accounts for up to 30% of operation cost for a water utility.
           

          II. SOLUTION IMPLEMENTATION

           

          Implementation methodology (main phases):

          1. Meeting with operators to understand the key step of the process: deep underground pumping, sand filters, chlorination.
          2. Instrumentation of the customer's electrical network with measurement devices connected to a web server.
          3. Analysis of the data collected by the Schneider Electric services team.
          4. Creation of an official report on a regular basis and presentation of the conclusions to the operation company staff.
           

          Duration:

          • 2 years: 2004 to 2006

          4. Modbus/Ethernet communication units
          5. Ethernet server information collection
          6. Information analysis
           

          How did we estimate the energy savings (methodology, tools, ...)

          • Energy savings were directly obtained by the reduction of the contract from a 600kW base to a 400kW base (winter subscription)
           

          III. RESULTS / ACHIEVEMENT

           

          Customer benefits:

          • The customer has a lower contract with the water utility.
          • He is able to manage the process to avoid peak demand: no filter backwashing during deep water pumping for instance.
          • Balancing of the pumps to limit ageing.
          • Pulsed air compressor optimisation.
           

          Customer testimonies (Verbatim):

          • Plant operation manager: "After 6 months of operation and the two first monitoring reports we have optimised the energy cost. We wish to extend the complete supervision of our electrical equipment on 2 pumping stations at Kecskemet."
           

          Schneider Electric differentiating values VS competitors:

          • Local service team collaboration with a local panel builder.
          • Full solution proposed by the same team including electrical equipment revamping, Ethernet TCP/IP transmission of data via a safe router, interpretation of data by experts, quarterly reports for recommendations.
