  • Dobrich RWO
  • Pernik RWO
  • Smolyan RWO
  • Sliven RWO
  • Stara Zagora RWO
  • Vratsa RWO

Specific objectives of the assignment include:

  • Screening of water companies’ operation processes and identifying areas with high energy intake;
  • Identifying proven EE measures available including energy management/digital solutions and energy generation measures (including RES) that drive better utility performance/operation;
  • Identifying and prioritizing key investments (up to EUR 10 million per company), which will have quick, but long-term effect on operators’ energy consumption.

 The Encon’s Team is responsible for implementing the following tasks:
