1. An energy control system comprising:
- a photovoltaic power generation unit connected to a grid and configured to generate power using sunlight;
a gas power generation unit configured to generate power using gas; and
a control unit configured todetermine whether sale of the power generated by the photovoltaic power generation unit to the grid is possible,when the sale is possible, automatically perform control to supply a load by prioritizing the power generated by the gas power generation unit over the power generated by the photovoltaic power generation unit, and,when the sale is not possible, automatically perform control to supply the load by prioritizing the power generated by the photovoltaic power generation unit over the power generated by the gas power generation unit.
