Last month, we pre-qualified a Battery Energy Storage System (BESS) for mFRR (manual Frequency Restoration Reserve) in Sweden in 10 days.

That process often takes around two months.

Even better: we got approval on the first submission: no feedback, no corrections, no extra rounds.

This sits on top of the milestone we shared before Christmas, where we delivered a BESS system in record time. Same theme. Same standard: move fast, ship clean, start earning early.

What we achieved (and why it matters)

mFRR prequalification isn’t paperwork theatre. It’s a trust test.

Your setup has to be right (configuration, tests, operations) because the grid depends on it.
So when you shorten that timeline without getting bounced back with comments, you’re proving two things at once:

• Speed (you can move)

• Quality (you can be trusted)

Timeline: from contract to trading to mFRR in SE2

Here’s the straight timeline, end to end:

• 26 days from contract to operation with WHES

• Control takeover on December 25, 2025

• Intraday + Day-Ahead trading live from December 26, 2025

• mFRR prequalification approved in 10 days (January 2026)

• Market area: SE2

And yes, SE2. Value doesn’t only live in SE3/SE4.

What this unlocks for BESS owners

When the asset is installed but not market-ready, it’s a parked race car.

Shortening the path to mFRR helps owners and developers:

• Start monetizing earlier (less idle time, faster revenue start)

• Reduce project risk (fewer loops, fewer delays, clearer delivery)

• Prove operational readiness (first-time approval is a quality signal)

Trading optimization: earn early, keep it stable

Getting to market quickly is step one.
The real work starts when trading goes live.

Our approach to BESS trading optimization focuses on:

• Consistent performance, not hype spikes

• Smart participation across Day-Ahead, Intraday, and balancing markets

• Dispatch strategies that don’t create chaos for operations teams

H2: Battery health optimization: protect the asset while you monetize it

Revenue is great. A degraded battery is not.

That’s why we pair trading performance with battery health optimization:

• Reduce unnecessary cycling

• Avoid high-stress operating patterns

• Balance short-term gains with long-term performance

Because the easiest way to lose money in storage is to win it too aggressively.

What’s next

We’ll keep pushing the same two outcomes:

1. Bring BESS assets to market fast

2. Maximize value without sacrificing battery health
