If you're running a battery and looking to maximize your earnings from energy exports, you might have wondered: Are some days better than others? Well, after analyzing the data from 2025 so far, we've found that not all days are created equal! Some days of the week—and even specific sites—are raking in incredible feed-in rates, while others are lagging behind.
Let's break it down and see which days have been the best for battery owners cashing in on high feed-in tariffs.
🔥 The Champions of Feed-In Rates
The absolute best-performing day for batteries in 2025 so far has been Saturday at Site 60, with an incredible 1,761.55 c/kWh in average earnings per kWh exported. That’s a massive payday for anyone shifting their energy exports to the right time slots!
Wednesday also dominates, with multiple site locations seeing huge rates:
Site 98 – $14.32/kWh
Site 47 – $12.76/kWh
Site 91 – $11.99/kWh
Meanwhile, Thursday holds its own, with Site 60 pulling in $7.36/kWh and Saturday at Site 106 seeing $7.16/kWh.
🏆 The Top 5 Battery-Friendly Days
Based on the highest feed-in rates across all locations, here are the best days to export energy:
Saturday – Huge earnings, especially at Site 60
Wednesday – Consistently high across multiple sites
Thursday – Strong mid-week performance
Friday – Decent rates, but not as dominant as Wednesday and Saturday
Tuesday – Some standout sites, but more variability
📉 The Least Profitable Days
While Monday and Sunday make appearances in the rankings, they tend to be at the lower end of the spectrum. For example, the best Monday site (Site 76) only hit 86.25 c/kWh, a far cry from the top Saturday numbers.
⚡ What This Means for Battery Owners
If you're looking to optimize your battery’s exports, aim for peak days like Saturday and Wednesday. These days consistently bring in the highest feed-in rates across different sites. Meanwhile, if you’re flexible, avoid lower-yield days like Monday and Sunday, unless the market shifts.
