Substation 15/30 kV of S. Roque
Substation of São Roque

The consortium Siemens/WinPower was selected by EDA for the design, Supply, Erection and Commissioning of the 30/15 kV substation of São Roque.

This project consists on the expansion of the existing São Roque substation, located in the Thermoelectric Power Plant of São Roque do Pico. This can be done by ensuring the connections of the new 30 kV transmission line between the substations of São Roque and Madalena; of the new 15 kV distribution line (São Roque 1); and the installation of a new 30/15 kV, 5 MVA transformer unit, with automatic voltage regulation, which will ensure the regulation of the voltage level on the distribution busbar of 15 kV, thus increasing the quality of service in the distribution of electricity from this new facility.

For this purpose, a dedicated building will be built to house all the equipment of the new substation and an outdoor equipment park, just for the assembly of the transformers. As part of the local distribution electrical grid, this new substation will allow the improvement of the electrical infrastructures of EDA, due to the boosting of the reliability of the system and of the required availability indexes.
