Southeast Asian PHES sites

The ANU is currently mapping pumped hydro energy storage sites throughout Southeast Asia – with detailed information for individual countries to follow. Protected areas have been excluded from these maps.

Fig. 1. Potential PHES locations in Southeast Asia. Red areas are highly prospective with potential heads better than 800 m. Other colours are also attractive, although with lower potential heads.

These sites were found using algorithms with defined search criteria within a geographic information system (GIS) platform. This platform was used to find detailed information, such as head, reservoir areas, and storage capacity. This list is not yet exhaustive. We are also in the process of developing a cost model that will determine the least cost option for the tunnelling between two reservoirs, and therefore the location of the lower reservoir. The Australian atlas can be accessed through the link below for reference – the additional information mentioned above will be available in future releases of the atlas.


Bali spreadsheet (xlsx, 431 K)

This spreadsheet contains a list of sites, and the basic characteristics of those sites. At this stage, matched lower reservoirs are not included. Head is assumed to be 400 m to allow an estimate of the potential energy storage.

The following Google Maps link provides the locations of the PHES sites (the reservoirs can be seen using the Google Earth files below):

Google Earth can be used to view the potential reservoirs. This software is free, and widely accessible. When used in 3-D mode with 3:1 vertical exaggeration, Google Earth provides good visualisation from any direction. This .kmz file can be loaded in the "Places" field to allow the user to visualise the potential reservoirs. These are shown with a representation of the dam walls. Clicking on a blue reservoir displays a pop-up with information about that reservoir, as does clicking on a dam wall.
