Spokesmen for the AEC-Dominican Power, a private energy generation company, said that the Los Minas plants will not be back on line until the end of the month. According to a report in the Listín Diario, the units have design problems that were detected after the new owners took over the installation from previous owners. They said that repairs that are taking place should definitely solve the problem. The CDE is dependent on private generators for the supply of about 50% of total energy served to the national energy grid.
