The electrical infrastructure consists of a total length of 4723.95 km of lines at 345, 138 and 69 KV, where the 345 KV network, which links the North Zone with the area of Santo Domingo, is the most economically important and functional one. It has a length of 129.9 km at a maximum transmission power of 1200 MVA per circuit. In addition,

In 2013, the total injection of electrical energy in the system was 13,850.9 GWh. The companies who supplied the most were AES Andres with 15.2%, HIDRO with 13.4%, EGEHAINA 12.6%, ITABO S.A. with 12.3%, SEABOARD 9.6% and DPP with a 9.2%. AES Dominicana units as a group contributed 36.6% of the energy in the Electricity Wholesale Market, reaching the highest market share in the generation sector.

the National Transmission System consists of approximately 2660.93 km of transmission lines at 138 kV and can be referred to as the Sub-backbone network; also 1933.13 km of 69 kV lines. It operates and maintains approximately
