The net export decreases when the installed capacity is close to equilibrium, with an internal peak of demand and sales. Increased net exports associated with marketing represents additional revenue for the system; moreover, a decrease in peak demand means less pressure on the electricity system to avoid operating higher-cost plants or needing to import electricity. The net export of 41,461 GWh in the full period from 2005 to 2025 produces an income of US$ 2073 million.
