IIEC Successfully Implements the Largest Energy Efficiency Project in the South Pacific

Featured Stories

Under the Pacific Alliance for Sustainability (PAS) program of the Global Environment Facility (GEF), the Asian Development Bank (ADB) provided technical assistance for the “Promoting Energy Efficiency in the Pacific (PEEP)” project. The project was co-financed by the GEF, Government of Australia, Japan International Cooperation Agency (JICA) and the Asian Clean Energy Fund (under the Clean Energy Financing Partnership Facility). During the implementation phase (PEEP2) from 2011 to 2015, the International Institute for Energy Conservation (IIEC) established policy and implementation frameworks, developed energy efficiency targets, and implemented a range of energy efficiency (EE) projects in the five participating Pacific Developing Member Countries (PDMCs): PNG, Vanuatu, Tonga, Samoa, and the Cook Islands. The overall goal of the project was to reduce energy consumption in the residential, commercial and public sectors in order to save energy, reduce fossil fuel imports, and lower greenhouse gas (GHG) emissions.

Under PEEP2, IIEC implemented 34 EE projects following ADB procurement guidelines. Grant funding from the GEF was provided for the procurement of EE equipment, while the installation costs were covered through co-funding from the recipients (e.g., hotels, government agencies). With a total investment of US$ 2,686,637, the project resulted in energy annual savings of 3,377 MWh, annual cost savings of US$1,519,629 and CO₂ savings of 3,204 tons/year. The average cost of saved energy across these projects varied from 3 to 11 cents/kWh—extremely cost-effective in comparison with the electricity tariffs in the PDMCs, which range between 29 and 61 cents/kWh.

Project outcomes also included:

· Development of an energy use database to provide access to information on electricity consumption and energy efficiency indicators at national and end-use sector levels.

· Development of national EE targets for the five PDMCs based on energy consumption and end-use energy savings projections for three policy scenarios – conservative, moderate and aggressive – for the years 2020, 2025 and 2030.

· Development of guidelines to support EE best practices, including an Energy Efficiency Technology Assessment; International Best Practices for Energy Efficiency Building Codes; a Green Hotels Rating Scheme for the Pacific; a Green Commercial Buildings Rating Scheme for the Pacific; Energy Efficiency Assessment Guidelines, Framework and Scorecard; and EE Guidelines for Hotels, Commercial Buildings and Street Lighting.

· Conduct of a comprehensive energy audit training in all five PDMCs, which included intermediate and advanced energy auditing, practical on-site training and preparation of Investment Grade Audit Reports.

· Preparation of a series of “Energy Saving Tips” for printing on the back of electricity bills and “Home Energy Guides” providing information on electricity costs for common electrical appliances (both efficient and inefficient) customized to each PDMC.

The PEEP2 guidelines, templates and implementation models would be suitable for scaling up EE implementation throughout the Pacific region.
