Industrial Electrical Substation

Industrial Electrical Substation, a solution conceived and designed by INEO Postes & Centrales for EDF, Rte and ENEDIS

An electrical substation is a component of the electrical grid used for both the transmission and distribution of electricity. It raises the electrical voltage for transmission and then lowers it for consumption by users (residential or industrial). Electrical substations are therefore key equipment for the continuous supply of energy.

Innovating to secure the energy supply

The industrialization of the electrical substation is proof that transmission and distribution systems are vital. The robustness and reliability of its equipment are a top priority. In order to meet the demand of its customer EDF, Rte and ENEDIS, INEO P&C has developed industrial electrical substations.

The Industrial Electrical Substation (IES) consists of a set of HV modules installed in a metal building, the whole constituting a "d" substation. The transformer cells and the HV premises have an independent structure and can be adjoined or dissociated from the P.E.I. building

The advantages of an Industrialized Electrical Substation (I.E.S.)

+ Discreet

The P.E.I. is more easily integrated in a peri-urban environment. From the outside, this closed building does not look like an electrical substation. In addition, the PEI technique requires 3 times less surface than its equivalent in open substation which also makes it easier to integrate them in cities;

+ Performing

The metal roofing increases the life span of the equipment, which is not subject to the vagaries of the weather. The first P.E.I. are 30 years old and our customers rarely call on us for maintenance.

+ Economic

From the design stage, thanks to the use of market components by INEO P&C teams, to the operation stage with the implementation of protection measures to deal with climatic hazards - such as tornadoes, frost, etc. - the global cost of a P.E.I. (including its operation and maintenance) is much lower than a traditional outdoor substation. Moreover, the technical and architectural choices have been designed so that each cell is insulated by boxes resistant to overpressures linked to short circuits, thus avoiding the "domino" effect in case of short circuits.
