Latvia’s New Imbalance Charge = A Direct Hit to Solar Profits
From 1 July 2025 every 15-minute mismatch costs about €40/MWh. Don’t pay it—fix it.
What It Means for Your Park
Forecasts slip 5–10 % on a good day, and can spike up to 20 %. Whatever strategy you’ve pencilled in, the grid still sends the invoice.
1 MWp Solar Park
Annual imbalance hit: €4 000–8 000
Break-even delay: ±12 months
5 MWp Solar Park
Annual imbalance hit: €21 000–42 000
Break-even delay: ±10 months
Forumula: MWp × 0.12 (cap-factor) × 8 760 h × error × €40/MWh
You know it, we know it—those charges land in Q3 2025.
Batteries: The Only Technical Fix
A smart EMS can watch errors happen.
A Battery Energy Storage System (BESS) erases them.
Buffers spikes & dips → no penalties
Sells stored kWh in peak hours → extra margin
Opens Frequency-Reserve markets → new income
Pick Your Path
You have three options: retrofit a C&I stack and curb penalties within weeks, add a utility-scale BESS for bigger or growing sites, or do nothing and watch imbalance fees drain profit.
