September 2026 - a new record for our model battery

Our model battery (2 MW, 4 MWh, RTE 0.86, DoD 100%), optimized on DA + IDC markets, could have generated as much as 126.2 kPLN in revenue in September.

📊 The strongest result since the market reform

This is the strongest result since the market reform, averaging 4,206 PLN per day. The 12-month rolling revenue has now increased to around 966 kPLN.

⚠️ A proposed tenfold increase in concession fees

At the same time, Poland's Ministry of Energy has proposed a 10-fold increase in the concession fee coefficients.

To put this into perspective, selling 1 MWh at 1,000 PLN/MWh results in:

• A 0.50 PLN concession fee under the current rules.
• A 5 PLN concession fee under the proposal.

⚡ What could this mean for intraday trading?

For active intraday trading, this could increase optimization costs and reduce the incentive to place some orders, potentially affecting market liquidity as well.
