  1. Energy Efficiency Measures in Moldovan Utilities GUTU SERGIU, May 08, 2014

  2. Content: • Why Energy Efficiency? • Performing Energy Audit • Putting in practice Energy Audit recommendations • Outcomes • Next steps

  3. National Water Supply and Sanitation Project (NWSSP) Urban Component: Balți, Cahul, Orhei, Floresti, Ungheni, Causeni. Rural Component: Valeni, Colibasi, Sarata-Noua, Bestemac, Pirita, Dubasarii Vechi, Navirnet, Sanatauca, Zahorna.

  4. NWSSP Components: Total Project Value: USD 12,8mln. World Bank loan Implementation Period: FY 2009- 2013

  5. Why Energy Efficiency? • WU use old and energy intensive equipment • Electricity consumption reaches over 28-35% of WU’s Operational Costs • Moldova is a Net Importer of energy from unstable markets

  6. Main stages:

  7. Methodologyunder Energy Audit: • Flow measurements at all water sources, all water and sewage pumping stations. • Outflow measurements of individual water and sewage pumps • Energy consumption of individual pumps and air blower • Team used pressure measurements equipment in order to evaluate actual performance of pumps and pressure piping • Acoustic leak detection using correlatorhas been performed

  8. Consultant prepared the following submittals, (Dec, 2011): • BoQ and Cost estimate for Goods, Works and associated services • Technical Specifications for Goods and Works within proposed Energy Management Program (EMP) • EMP schedule of implementation

  9. Solutions applied in Balticity Before After

  10. Outcomes: -42% -50% -35% -68%

  11. Outcomes:Electricity Consumption reduced by: Total investment: 1,1 mlnUSD; Total Savings: 0,3mlnUSD/year; Payback period 3,7 years; kWh/year

  12. Other benefits: • Industrial productivity and competitiveness • Poverty alleviation: Water affordability and access • Reduced GHG emissions • Sustainable Natural resource management • Development goals

  13. Complications: • WUs are still using energy intensive equipment, and obsolete distribution system • Given limited human, and technical capacity WUs are not able without foreign assistance to replicate Energy Efficiency • Political instability, and multiple elections (two local elections; three parliamentary elections; one referendum) • Socially oriented tariffs inhibit development • Limited borrowing capacity of WUs and local municipalities

  14. Next steps: • Further extension of energy efficiency programs • Continuous building of institutional capacity • Regional development in the water sector
