Energy Savings Initiatives Sample Clauses

Energy Savings Initiatives. A separate report has been prepared under the PPTA consultancy on energy savings initiatives for SAWACO. In conjunction with a local energy auditing consultant, MWH has conducted energy audits at locations covering the full range of operations across HCMC’s water supply system. The following sites were included in the audit. • Thu Duc WTP – Raw Water Pumping • Thu Duc WTP – Treated Water Pumping • Thu Duc WTP – Backwash System • Thu Duc WTP – Office, Workshop, Ancillaries • Xxx Xxxx WTP – Raw Water Pumping • Xxx Xxxx WTP – Treated Water Pumping • Xxx Xxxx WTP – Backwash System • Xxx Xxxx WTP – Office, Workshop, Ancillaries • Thu Duc BOO WTP • Xxxx An WTP • Xxxxx An Water Supply Company • Hoc Mon WTP • SAWACO Headquarters Offices • JS Company Office Zone 3 • JS Company Office Zone 5 At each location the key energy using items were noted and energy saving measures were identified and cost estimates prepared. The measures have been sorted into four groups: no cost, payback period up to 3 years, payback period up to 3 to 5 years and payback period greater than 5 years. The capital costs of these groups are shown in Table 3-2. Table 3-2 Costs of Energy Savings Measures Payback Period US$ million VND million No Cost 0 0 Short Term 0 to 3 years 1.5 27 Medium Term 3 to 5 years 0.75 13 Longer Term greater than 5 years. 2.9 52 The most significant short term payback measure is the installation of Variable Frequency Drives (VFDs) for the treated water pumps at WTPs. This has an estimated cost of US$1.3 million (23.7 billion VND) and a payback period of 2.8 years. Another significant item because of the short payback period is the modification of the filter backwash process at the Hoc Mon WTP. This has an estimated cost of US$16,000 (286 million VND) and a payback period of 0.36 years. Other short term pay back measures include installation of VFDs on pumps, of higher efficiency fluorescent lamps, of extra transformers, of more efficient pumps, of capacitor banks, and of more efficient air conditioners. Many of the medium and longer term payback measures are the same as the short term ones mentioned above. Under the Climate Change Adaptation project the consultants will provide support to SAWACO for introduction of these initiatives during project implementation. SAWACO is considering implementing the energy savings program with its own funds.
