Benefits of Batteries:
- Lower energy costs
- Provides independence
- Backup system
Reasons Batteries Reduce Energy Costs:
- Lower Procurement Costs: Because the Dutch energy price is announced 24 hours in advance, with a battery, you can purchase energy at the lowest price of the day.
- Peak Shaving: Peak shaving is a strategy where you manage electricity demand and reduce peak loads on the electricity grid. This is done by compensating energy consumption with energy from the battery.
- Load Shifting: Load shifting reduces consumption peaks by moving energy usage from peak hours to off-peak hours.
- Energy Price Speculation: Because energy costs are announced 24 hours in advance, with a battery, you can consume energy at low or negative costs and sell it at higher prices.
Calculating Battery Capacity:
Battery Capacity (kWh) = Average Daily Usage (kWh) x Autonomous Days / DoD
- Battery Capacity = the required capacity for your system
- Average Daily Usage = the energy you need daily
- Autonomous Days = the number of days you want to be independent of the electricity grid
- Depth of Discharge (DoD) = the battery's discharge percentage
