Around 70% of planned power capacity is
locations considered either water stressed
or water scarce.
In India, severe water scarcity will amplify competition for water and determine
thermal plants competitiveness and location – while cooling demand grows

In China, water constraints could make
the expected increase in thermal power
output unachievable, in particular, as
60% of thermal power capacity is in
northern China, which as only 20% of
freshwater supply.

Storms, heavy rainfall and increased temperature will impact the power system
