Palau : Energy Transition Project (formerly Smart Grid Project)

Sovereign Project | 49450-037

The project will install a total of 15 megawatt hour battery energy storage system (BESS), which will enable the grid to increase the utilization of outputs from the solar photovoltaic power plant and provide grid services to Koror-Babeldaob grid to equip Palau Public Utilities Corporation (PPUC) with tools to optimize the use of renewable energy. Protection systems will also be upgraded to reduce the frequent blackouts of the grid system, especially with the expected increase of outputs from the solar photovoltaic power plant. The project also includes a pilot vehicle-to-grid project, as a future option for further optimization of renewable energy generation.

Project Rationale and Linkage to Country/Regional Strategy

Although Palau enjoys almost 100% electrification rate, it relies heavily on imported diesel for power generation. Over 97% of power generation is based on fossil fuel (diesel) and 3% on solar. To reduce reliance on fossil fuel and to meet the Nationally Determined Contribution target, Palau plans to integrate renewable energy through (i) two phases of independent power producers (IPPs) engagement, and (ii) solar roof top installations. The first phase of the IPP project (IPP-1) is expected to be complete with a 13.2 megawatt-peak (MWp) solar system and a 15 megawatt-hour (MWh) battery energy storage system (BESS) by early 2024. This IPP-1 solar system will bring the share of renewable energy to 20% of Palau's generation mix if the grid can accommodate its outputs. This will depend on optimizing the intermittent outputs of IPP-1 by minimizing curtailment.

PPUC plans to install a BESS in its grid system to achieve this goal. Reducing curtailment is critical to optimizing PPUC's operational efficiency because of the take-or-pay arrangements in the power purchase agreement. In addition to BESS, the government plans to make better use of IPP-1 generation capacity with an introduction of vehicle-to-grid (V2G) solutions. As a small island nation with limited demand for equipment necessary for V2G, a public sector pilot initiative is needed to test and showcase the effectiveness of V2G solutions.

Summary of Environmental and Social Aspects

Environmental Aspects
The project has been screened and is classified as Category B for environment with an initial environmental examination (IEE) and environmental management plan (EMP) prepared. The IEE and EMP outline all assessed risks and mitigative actions to be undertaken in the management, monitoring, and reporting requirements for environmental compliance of the project.
Involuntary Resettlement
The project is categorized C for involuntary resettlement and indigenous peoples. Land ownership in Palau is exclusively vested in the state. The due diligence conducted for the project confirms that proposed project investments will be installed on government owned land (public land) and will not require land acquisition nor cause any physical or economic displacement. The project is not expected to impact any distinct and vulnerable group of indigenous peoples as defined under ADB's Safeguard Policy Statement. The project will ensure that the local communities actively participate and receive culturally appropriate benefits.
