Framework contract for station construction components for the years 2022 to 2025. Beginning of the framework contract 1.12.2021.

The framework agreement includes the production and delivery of turnkey walk-in and non-walkable 10kV compact stations for use in ENERVIE Vernetzett GmbH's network area and for sale to its customers.

In addition, the supply of individual components for station conversion.

ENERVIE Netzett is writing out a framework contract for the renewal of 10kV medium-voltage stations as well as for continuous grid expansion and renovation for the supply of compact walk-on — and compact non-walk-on stations. This also includes individual components such as 10 kV medium voltage switchgears and low-voltage scaffolding for the renovation of existing stations for retrieval.

The following components are part of the framework contract:

1. Delivery of factory-ready walk-on and non-walkable compact transformer stations in monolithic concrete construction with fault arc testing according to DIN EN 62271 — 202 mainly for own use in grid expansion.

Completely equipped with SF6 insulated (maximum 4 fields) metal-encapsulated medium voltage switchgear and power distribution transformer up to 630kVA with fault arc testaccording to DIN EN 61936-1, rated voltage ur = 12 kV, low voltage main distribution in open touch-proof scaffolding design, each as provided off the framework agreement.

If necessary Distribution of own demand (supply), settlement converter (supply), meter housing (supply) and station accessories.

Completely wired inside the concrete body (medium voltage, low voltage, self-consumption and grounding, free use point in the prepared excavation pit.

2. Delivery of factory-ready walkable and non-walkable compact transformer stations in monolithic concrete construction with arc testing according to DIN EN 62271 - 202 for installation in slopes mainly for self-use in grid expansion.

Completely equipped with SF6 insulated (maximum 4 fields) metal-encapsulated medium voltage switchgear and power distribution transformer up to 630kVA with fault arc testaccording to DIN EN 61936-1, rated voltage ur = 12 kV, low voltage main distribution in open touch-proof scaffolding design, each as provided off the framework agreement.

If necessary Distribution of own demand (supply), settlement converter (supply), meter housing (supply) and station accessories.

Completely wired inside the concrete body (medium voltage, low voltage, self-consumption and grounding, free use point in the prepared excavation pit.

3. Delivery of factory-ready walk-in and non-walkable compact transformer stations in monolithic concrete construction with fault arc testing according to DIN EN 62271 - 202 mainly for resale to Mark-E Effiziency GmbH industrial customers..

Completely equipped with SF6 insulated (maximum 4-panel) metal-encapsulated medium voltage switchgear and power distribution transformer greater than 630 kVA to 1,600 kVA with arc fault test according to DIN EN 61936-1, rated voltage ur = 12 kV, low voltage main distribution in open contact-proof scaffolding design, each as provision from the framework agreement.

If necessary Distribution of own demand (supply), settlement converter (supply), meter housing (supply) and station accessories.

Completely wired inside the concrete body (medium voltage, low voltage, self-consumption and grounding, free use point in the prepared excavation pit.

4. Supply of factory-ready, type-tested medium-voltage switchgears in SF6 technology according to DIN EN 61936 - 1.

Execution as a unit (block).

— Delivery of factory-ready, type-tested medium-voltage switchgears in SF6 technology according to DIN EN 61936-1.

Design can be baying as single fields or panel blocks.

— Delivery of factory-ready, type-tested medium-voltage switchgears in SF6 technology according to DIN EN 61936-1.

Execution as a single unit (block), but without the need to take pressure dissipation measures.

5. Low-voltage main distributions in open touch-proof scaffolding design both for installation in a factory-ready compact station and for replacement in existing switching stations.

6. Supply of components to produce an intelligent local network station. The 10 kV medium voltage switchgear must be remotely controlled by means of motor drives on the load switches. Messages and measured values must be remotely transferable using mod bus and modbus-enabled telecontrol technology.

The entire plants cannot be specified in more detail at the moment. In the expected concept of implementing the framework agreement, the bidder requires a detailed description of the experience of using these technologies.

From today's perspective, the service specifications represent the demand for a continuous station renewal program up to 2025. The volumes are based on the estimates of expansion capacities and the financial resources provided for this from 2022 to 2025.

The changing framework conditions in terms of sustainability and security of supply in terms of ever-growing requirements from renewable energies and increased energy requirements for the expansion of e-mobility infrastructure are not taken into account.

Framework contract for power distribution transformers oil-cooled in hermetic version with fully encapsulated and non-contact connections (power sizes 100 kVA, 250 kVA; 400 kVA; 630 kVA, 1,000 kVA and 1,600kVA). The transformers must be made available to the manufacturer of the concrete building in the form of a consignment warehouse.

The quantities and contract modalities to be provided will be announced in the service descriptions.
