For the bus depot of HEAG mobilo GmbH at Klappacher Str. 172 in 64285 Darmstadt, ENTEGA AG intends to procure a charging infrastructure including the necessary power supply technology. This includes all components starting from a transfer station for the connection to the medium-voltage grid of the distribution system operator, via 2 transformer stations for the supply of low voltage up to the charging stations incl. Charging rectifiers and DC charging points.

- Lot 1 charging infrastructure,

- Lot 2: electricity supply system.

- Lot 1 - charging infrastructure:

The subject of the invitation to tender in Lot 1 is the technical project planning, supply, erection and commissioning of 28 DC charging stations with a charging power of 150 kW at the depot of HEAG mobilo GmbH. For this, the necessary charge rectifiers outside of the depot, the wiring incl. The connection to the low voltage outlets of the transformer stations as well as the connection of the depot and the individual charging points in the depot must be set up by AN of lot 1. Any necessary civil engineering work, the construction of foundations and cable trays are also included in the scope of services of lot 1. The erection of the charging stations will take place in 3 construction phases up to and including 2021.

- Lot 2 - Power supply systems:

For the connection of the charging rectifier lot 2 a transfer station, 2 transformer stations with medium voltage, low voltage and Traforaum as well as a middle voltage ring are to be established. The transfer station serves as a grid connection point for the medium-voltage grid (20 kV) of the distribution system operator. Starting from the transfer station, 2 transformer stations are connected with a medium-voltage ring. In addition to the transfer station and the transformer stations, the contractor of lot 2 also creates the medium-voltage ring, whereby the necessary civil engineering for the medium-voltage ring is awarded in a separate order.
