Flexibility
The first outcome foreseen from the country’s
long-term objectives is a shift from dispatchable
to non-dispatchable generation. Between 2019
and 2030 the share of dispatchable generation
is expected to fall from 94% to 79%. This shift
in the energy supply accompanies a sustained
increase in electricity demand of 0.6% per
year, and a 1.1% yearly increase in peak load.
