The model is based on several elements:
Revenue:• Electricity sales between members (preferential price)
• Resale of surplus to the grid
• Green certificates and guarantees of origin
• Subsidies and public aid
Costs:• Initial investment (production, meters)
• Management and maintenance fees
• Administrative costs
• Insurance
Average savings:• 20 to 40% on energy bills
• Typical ROI: 7 to 10 years
Profitability depends on optimizing these different parameters.
