As a general rule, the termination of a ECA ends with the agreed commercial operating period. A ECA may be terminated in the event of abnormal events or circumstances which do not comply with the provisions of the Treaty. The seller has the right to reduce the supply of energy when such abnormal circumstances occur, including natural disasters and uncontrolled events. The ECA can also allow the buyer to reduce energy if the value of the electricity changes after taxes.  In the event of a lack of energy, this is usually due to the fault of one of the parties involved, resulting in damages paid to the other party. This can be excused in exceptional circumstances such as natural disasters, and the party responsible for repairing the project is responsible for such damages. . . .
