The scope of work for this tender include design, engineering, production, erection and energizing of a total High Voltage System including:

50/10 kV power transformer

10 kV switchgear

Distribution transformers

Low voltage panels

Halsnæs Forsyning is supplying approximately 21.000 households with district heating and have a yearly heat production of 100.000 MWh.

Halsnæs Forsyning plans to establish a new heat production plant equipped with a 30 MW electrical boiler and a 10 MWth Air to Water heat pump. The plant will be prepared for an expansion of an additional Air to Water heat pump of 10 MWth.

The power supply for the plant will be from the public 50 kV grid. The point of connection (POC) is at the 50 kV station VAL, located nearby. The grid company NEXEL will install 50 kV bay at VAL. Halsnæs Forsyning will connect cable from the bay to the heat plant. The delivery and installation of 50 kV cable is handled in another purchase.

The overall project is divided into the following sub-contracts:

1. High Voltage System (present contract)

2. Cable and Cable Work for 50 kV Station to site

2. Buildings and foundations for Installations

3. Electric Boiler

4. Air to Water Heat Pump

The High Voltage Project (this tender) include engineering, production, erection and energization of the power supply for the heat production components.
