To put things in perspective, here’s how my electricity bill in Estonia breaks down. I have PV panels, and my ESS runs in trading mode.
June:
- 17% electricity (Nord Pool)
- 54% grid costs (variable grid fee)
- 29% taxes (renewable tax, electricity duty tax, VAT)
Excluding taxes, electricity vs. grid costs were 24% vs. 76%.
June was a cheap-kWh month and shares vary across the year, but as my system grows and becomes more efficient—and as I add more batteries — grid fees account for a larger share of the bill.
