Phase I: making a difference

Phase I (Middle Governorates)

Overview: Energy Audit Outcome

  • Identified energy savings potential in pumping stations ranges from 4% to 65%
  • In total a saving potential of 21 million kWh per year (25%) and 935,000 JOD or 15,700 t CO2 per year was identified
  • 4 to 13 years pay-back periods (for private sector investment)
  • Life Cycle Costing not applied for procurement of pumping equipment
  • No regular inspections & overhauling of pumps
  • Fragmented organisation structure in WAJ
    • Core Challenge: Institutional changes needed, not only investment
    • Energy Performance Contracting (EPC) identified as a promising approach
    • Assessment within the IEE Programme has shown that proper operation & monitoring (O&M) of pumping stations is indispensable to achieve energy savings.

Part 1: Energy Audit

With a consulting consortium led by Dorsch International Consultants GIZ conducted an energy audit (study) for major consumers of pump electricity in the three governorates of Balqa, Madaba and Zarqa. This energy audit consisted of the collection and analysis of pump performance measurements and electro-mechanical investigations. To this end water flow, pressure and electricity consumption was measured, as was the system performance. Based on the derived factual efficiency, the energy saving potential was calculated assuming the use of improved technology and better operations. As part of the audit also the required investments to implement retrofit measures was estimated and technical measures to reduce the energy consumption were developed.

The analysis carried out within the Water Schemes in the Middle Governorates has shown the limited capacities in staff qualifications of WAJ to operate, maintain and overhaul their pumping stations. The existing situation is the result of inappropriately sized and operated pumps and insufficient quality of maintenance and repair processes due to lack of qualified staff, substandard equipment and most important split responsibilities among different WAJ units. The outcome is low performance of the pump efficiency, high operation costs and high energy costs. The frequent pump failures and breakdowns requiring emergency replacement with often not suitable pumps. Most of the maintenance is executed on emergency basis in case of pump failures. This further increases inefficiency and wear and tear at the used equipment and infrastructure.

A large number of divisions and actors are involved in the process starting from the designing and selection of pumping facilities to operations, maintenance and repair. The responsibilities for pump operation and maintenance are fragmented between the different departments and bureaucratic procedures for procurement of spare parts and tools as well as low performance incentives result in the actual problematic situation of pumping facilities. Water utility procurement laws put the focus on the cheapest purchase cost for pumps and equipment and prevent an orientation at life-cycle-costs when new pumps are procured. This implies that relatively low-quality and cheap pumps are being procured, which have due to their electricity consumption and higher repair and maintenance needs much higher life-cycle costs than high-quality pumps. The conclusion had to be that simply procuring new high efficiency pumping infrastructure would not help to find a sustainable solution to the mentioned challenges.

Conducted energy audits do not only contain information about electricity consumption and improvement potential, but also give detailed recommendations for measures how the energy saving potential can be reaped. Besides the technical issues, the findings show also the need for institutional change processes. Especially with regard to the fragmentation of responsibilities and the lack of coordination for the involvement of the different units, which prevent a coherent optimised design and operation.

Together with the private sector, the IEE Programme therefore aims to optimize WAJ’s process regarding pump station design, retrofit, operation and management. The focus of the approach is to include innovative technologies and high private sector investment within the different private sector participation (PSP) and contracting models developed by the IEE Programme.

 

Part 2: Implementation

Measures and methods derived from the initial energy audit are implemented. The idea is to use private sector operational expertise and private finance as far as possible, eg. for rehabilitating and operating pumping stations to achieve sustainable improvements. This means that beside direct procurement and improved operation of pumps, the investments in and the operation of pumping stations might be outsourced by WAJ to the private sector for a predetermined number of years. In addition, investments for selected stations were implemented from within the budget of the IEE Programme.
