A battery for full ERE credits? Charge during the day instead

Translated from a LinkedIn post in Dutch.
ERE credits (emission reduction units) are the Dutch system that rewards renewable electricity delivered to transport. Home chargers with solar panels are getting fewer ERE credits than they expected, Dutch newspaper de Volkskrant wrote this week. The Dutch Emissions Authority (NEa) only counts what you take from the grid on balance, and for private individuals solar power counts at the grid average of 50.5%.
Businesses, however, may register their own solar power as 100% renewable: 0.66 ERE per kWh instead of 0.33. Even via a battery. Does it pay off? I calculated four scenarios for a truck that charges 55,000 kWh a year.
Charging costs per year, after ERE credits:
- Do nothing, charge at night: € 8,250
- Battery, the solar power had no other use: € 3,990
- Battery, while the building could use the solar power itself: € 7,840
- Daytime charging, directly from the panels: € 510
Registering ERE credits for your grid power costs nothing and already brings you to € 2,780.
The battery shifts solar power to the night. If your building uses that electricity itself during the day, you buy it back there. What remains is the extra ERE credits, and they do not pay back the battery.
The gain is in the planning: charge the truck when the sun shines.
What does this mean for your company? The Charging Scan calculates it based on your own electricity use and trips. All scenarios and charts are in the article Full ERE credits for solar power: four scenarios.
