The demand for the island is between 17 MW and 18 MW, which an off peak demand a low as 8 MW especially in the cooler months of the year.

The pre Maria customer base was over 36,000 with an average monthly electrical energy consumption of 8.4 GWh.

1.3 Impact of Hurricane Maria

Hurricane Maria made a direct hit on the Commonwealth of Dominica on September 19, 2018, resulting in widespread damage and destruction across the island and affecting all sector of the economy. The electricity sector was affected as follows:
