Our model battery (2 MW, 4 MWh, RTE 0.86, DoD 100%), optimized for DA + IDC, could have earned 97 thousand PLN - the second-highest result over the past 12 months!

📊 As a result, the 12-month rolling sum has slightly increased again, reaching 892 kPLN.

📈 Interestingly, September 2025 revenue is nearly identical to the same month last year - but this time, the share of the Day-Ahead Market in total revenue is lower.

Is this a sign that the Polish energy market is starting to stabilize?

Perhaps the growing number of RES units is now balanced by increased gas-fired generation capacity.

⚠️ Meanwhile, an important change in the Day-Ahead Market (SDAC)

As of October, Fixing II auction is now settled every 15 minutes instead of hourly! We’ll soon show how this impacts BESS strategies and revenue potential - stay tuned.
