- The RNG potential index is an indicative tool intended to highlight areas where feedstock potential and proximity to the grid converge. It does not, on its own, constitute a decisionmaking tool for project implementation. It does not replace the need to conduct additional analyses, particularly technical and economic assessments.
Additionnal informations (see map legend)
[1] Before considering any project on the gas network, a hydraulic capacity addition request must be submitted to and approved by Énergir. You may submit a request at: [email protected]
[2] The TQM and TCPL gas transmission networks are operated by entities that are distinct from Énergir. Data on the hydraulic capacities of these networks is not publicly available. Connecting a RNG project to the TQM/TCPL network requires the submission of a specific request and may incur additional costs.
[3] The quantities of corn-grain residues presented were estimated using the following methodology:
- Availability of residues: only for agricultural soils containing more than 4% organic matter (SOM).
- For these lands: the harvest rate was estimated in order to maintain a positive humus balance. This rate was determined by taking into account:
- the removal of corn-grain residues;
- and the return of raw digestate (approximately 2 t SOM/ha).
RNG potential Index
Objective:
Identify areas that offer favorable conditions for the development of RNG production plants.
- The index is calculated by combining the following key factors: Index = Network Factor × Feedstock Potential Factor
- Network Factor – Proximity to and capacity of Énergir’s gas network:
- This factor increases with proximity to the network within a zone whose width is proportional to the network’s capacity. The value is highest in the immediate vicinity of the network and decreases with distance.
- Feedstock Potential Factor – Combined production potential
- This factor corresponds to a weighted sum of the densities of available materials:
- Density of animal resources: 80% of the weighting
- Density of crop residues: 10% of the weighting
- Density of industrial, commercial and institutional residues: 10% of the weighting
- Finally, the index is slightly adjusted downward based on the phosphorus load specific to each region.
