Biomethane injection points

Conexus Baltic Grid (Conexus) has developed a solution that enables biomethane producers to inject produced biomethane into the transmission system using public Biomethane Injection Points (BIP), supported by a smart system. The biomethane is transported to the injection point by road as bioCNG in high-pressure containers (250–300 bar).

This solution is especially important for producers whose facilities are located far from the gas transmission or distribution networks and for whom a direct connection would not be economically or technically feasible. In Latvia, only a small number of potential biomethane production sites are located close enough to existing gas infrastructure to justify direct system connections.

To promote the development of biomethane production throughout Latvia, Conexus is implementing the so-called “virtual pipeline” concept. Under this model, biomethane is transported via public roads and injected into the system at specially designed public points. Each BIP provides:

  • Safe injection of biomethane into the transmission system,
  • Quality control and metering,
  • Identification of the transporter and supplier,
  • Remote monitoring and control.

Based on the location of existing biogas plants and the results of public consultations, Conexus has identified several potential locations for future BIP development, depending on available financial resources.

 

First public biomethane injection point “Džūkste”

On July 28, 2025, the first public biomethane injection point “Džūkste”, located in Džūkste parish begins operations. Producers will also be able to receive Guarantees of Origin for sustainably certified biomethane injected via the Džūkste BIP.

Quality, Metering, and Balancing at the BIP

Conexus continues to actively develop the gas market by providing safe and accessible infrastructure, while also working on new solutions for the injection and transportation of sustainable gases.
