Promoting Energy Efficiency in the Pacific (Phase 2) - PEEP2 Summary Report on Assessment of Energy Efficient Technologies for the Pacific

Report prepared for Asian Development Bank, by International Institute for Energy Conservation - Asia. 5 countries are part of this PEEP2 programme: Cook Islands, PNG, Tonga, Samoa, Vanuatu. In these Pacific Developing Member Countries (PDMCs) , a number of new/innovative end-use technologies are likely to be applicable for improving energy efficiency in a cost-effective manner as well as reducing energy use and Greenhouse Gas (GHG) emissions. The purpose is to identify and assess a range of applicable energy efficient low carbon technologies for the five PDMCs.

In this regard, energy efficient technology options for the following types of technologies were evaluated:

a)    Small Air Conditioning (AC) Technologies - wind, split, split plus inverter & solar air conditioning systems

b)    Medium and Large Air Conditioning Technologies - VRV/VRF, reciprocating, screw, scroll chilers, HVAC systems with VFD

c)    Water Heating Technologies - heat water pump heaters, solar , gas water heaters

d)    Lighting Technologies

The project team identified the various energy efficient technologies that are applicable in the PDMCs and this summary report presents findings of the assessment of these technologies. The evaluated technologies were assessed based on Cost of Conserved Energy (CCE), Net Present Value (NPV) and Internal Rate of Return (IRR) using a generic spreadsheet model. The evaluation of the proposed energy efficient technologies was undertaken for two scenarios, namely, (i) replacement of old technologies by new technologies, and (ii) purchase of new technologies for new installations.
