The evolution of the yearly gas demand for power generation, as seen in the figures
above, follows the trends set by the thermal gap. In Vision 3, as seen in the figure
below, the thermal gap decreases in the short term driven by the increase in renew-
able power generation, and increases sharply in the long term, when the increase in
renewables does not match the significant growth in electricity demand.

1) As the thermal gap defines the electricity generation which has to be provided by coal and/or gas-fired power generation
it is expressed in electrical units.
