According to WRI's report "Over Heating: Financial Risks from Water Constrains on Power Generation in Asia," the majority of existing and new power generating capacity for publicly listed companies in South and Southeast Asia are located in areas classified as water scarce and stressed.

This figure provides a preliminary picture of water scarcity in areas of power generation. WRI mapped over 150 existing and planned thermal and hydro power plants from the largest publicly listed power generation companies in the region by using data from corporate financial reports and http://carma.org. Planned capacity includes all stages of project development reported in corporate financial disclosures but not yet operational in 2009. Water scarcity data is from the International Water Management Institute, WRI, and the University of Kassel. These indicators do not include important elements of water risk, including future climatic changes and demographic trends. For example, plants located in regions classified as water abundant may face risks due to changes in the timing of precipitation patterns.
