EGS & BESS

Let’s work together to put the energy strategy into practice.

You are making a valuable contribution to a renewable future and/or potential performance reserves in the form of balancing energy. We are happy to support you in your project and thus contribute to your important commitment. Let us work together to achieve the goals of the Energy Strategy 2050.

Technical connection conditions for EGS and storage

When implementing an EGS, please note our TCC for EGS. These also apply for storage units.

Technical connection conditions (TCC) for the parallel operation of energy generation systems (EGS) and storage units in the Primeo Energie power supply network

• Appendix B2: Grid diagram for EGS > 30 kVA
• Appendix B1 explanation: Activation of EGS ≤ 30 kVA with contactor as alternative

Factory acceptance and standards to be set

Primeo Energie carries out a factory acceptance test at all EGS sites. The producer confirms to Primeo Energie that all specifications have been complied with and that the settings are in line with the TCC for EGS.

As a rule, and unless otherwise stated on the application for connection, the current country setting for Switzerland must be set in accordance with NA/EGS-CH. Alternatively, the current VDE-AR-N 4105:2018—11 data record (or for medium voltage 4110) can be selected in exceptional cases. Older country rates which are no longer valid may no longer be used.

For EGS > 3.6 kVA with Type 2 converter, characteristic curve Q(U) must be set in accordance with Appendix D of TCC for EGS (static grid support). With an output ≤ 3.6 kVA, cosφ = 1 can be used.
