Retendering Framework agreement for certified and CE marked LoRaWAN modbus node

Beskrivelse fra ordregiveren

Energinet has high-voltage (up to 400 kV) circuit breakers filled with gas SF6. To reduce the amount of leaked SF6. It has been requested that Energinet should be able to monitor leakages more closely so that Energinet can react faster than today. With the Framework Agreement Energinet wants to buy LoRaWAN nodes for transferring the data from the hybrid gas density monitor to Energinet. 1. Background Energinet, who is the Danish TSO (Transmission System Operator), has high-voltage circuit breakers filled with gas SF6 which is a very CO2 polluting gas variant. 2. Purpose Energinet wants to be able to replace the existing gas density monitor with a new Hybrid gas density monitor, which is capable to monitor the pressure in the breakers and thereby collect different data and analyze the trend over time and identify SF6 leakages early in the process. The Hybrid Gas density monitor must be able to communicate with a communication node which is transferring the data, via LoRaWAN, to Energinet. 3. Scope of this tender The scope of this tender is to provide a framework agreement enabling Energinet to purchase LoRaWAN nodes for surveying our SF6 filled components. The LoRaWAN nodes will be put into tender, but recipient LoRaWAN gateway is Energinet's own responsibility and coverage, so the LoRaWAN standard becomes the dividing line between tender and Energinet and is not part of this tender. The tender will only be focusing on the delivered products and there will be no need for a maintenance agreement, as we aim to get a deploy and forget solution. Energinet is currently looking into a demand of 2.400 units which need to be mounted on our AIS breakers. 4. Energinet's market knowledge Energinet currently uses products from Adeunis. Through market knowledge Energinet believes that products such as Adeunis Modbus LoRaWAN EU863-870 or Dragino RS485-LN Modbus to LoRaWAN Converter or similar products can meet most of the requirements in the tender. For more information see the Tender Conditions and Appendix 2 on the tender platform EU-Supply.
