May 2026 delivered another solid result for our model battery (2 MW, 4 MWh, RTE 0.86, DoD 100%), optimized on DA + IDC markets. The battery could have generated 93 kPLN in revenue.

📊 Key takeaways

  • 4.5% higher revenue than in May 2025.
  • 1.1% higher revenue than in April 2026.
  • 3,001 PLN in average daily revenue.
  • Around 895 kPLN in 12-month rolling revenue.

⚡ Fewer cycles, more valuable opportunities

Interestingly, the number of cycles dropped to around 1.24 cycles per day, which was lower than in both April and March. Yet revenues did not decline. This means that the optimizer had access to more valuable daily opportunities.

📈 Can Q2 2026 set a new record?

Q2 2025 has so far been the best quarter for our model battery since the market reform in June 2024.

For Q2 2026 to beat that result, June would need to deliver around 99 kPLN in revenue (June 2025 was almost 104 kPLN).
