In this example we look at a cold store with 650 kWp of solar panels and a 1,200 kWh battery. The figures are an example; for your own site we calculate with your own quarter-hour data.
| Source of benefit | Per year (example) |
|---|---|
| Day-ahead and intraday trading | €26,000 |
| Imbalance | €15,000 |
| aFRR/FCR balancing services | €12,000 |
| Peak shaving | €12,600 |
| Solar self-consumption and avoided negative prices | €7,600 |
Two scenarios
Market prices fluctuate. That's why we always calculate with a cautious scenario and a base scenario. In this example the payback time is between six and seven years.
