Energy Efficiency Measures in Moldovan Utilities GUTU SERGIU, MAY 08, 2014
Content: I. Why Energy Efficiency? II. Performing Energy Audit III. Putting in practice Energy Audit recommendations IV. Outcomes V. Next steps 2
National Water Supply and Sanitation Project (NWSSP) Urban Component: Bali, Cahul, Orhei, Floresti, Ungheni, Causeni. Rural Component: Valeni, Colibasi, Sarata-Noua, Bestemac, Pirita, Dubasarii Vechi, Navirnet, Sanatauca, Zahorna.
NWSSP Components: Total Project Value: USD 12,8 mln. World Bank loan Implementation Period: FY 2009- 2013 4
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 5
Main stages: Contract duration Budget, (USD) Weigh, (%) Energy Audit6 months230.00021 Implementation18 months870.00079 Total:1.100.000100 6
Methodology under 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 correlator has been performed 7
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 Balti city Before After 10
Outcomes: Electricity Consumption reduced by: kWh/year Total investment: 1,1 mln USD; Total Savings: 0,3 mln USD/year; Payback period 3,7 years; 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 15
