To ensure economic viability of a project, we generally recommend:

• Minimum annual consumption of 400 MWh

• Minimum annual production of 250 MWh

• Minimum of 10-15 participants to diversify profiles

• Collective self-consumption rate of at least 30%

These thresholds may vary depending on local context, energy tariffs and available subsidies.
