Summary
E.ON Energidistribution’s page for its pilot flexibility market in Halland (SW Sweden), launched summer 2025. The market is Sweden’s first local flexibility market with a focus on production load (produktionslast) — distinct from E.ON’s existing SWITCH markets, which focus on consumption. Five named participants contributed testimonials at launch.
Key claims
The problem being solved
During summer months, total electricity production from renewables (solar, wind) can become very high while consumption is low. This can cause capacity challenges in parts of the grid. By actively curtailing production loads or increasing consumption during peak hours, the grid can be used more efficiently — enabling faster connection of more production facilities without requiring extensive grid expansion. Halland is specifically identified as an area that can face capacity challenges in summer, having seen rapid growth in electricity production from solar and wind.
How the market works
- E.ON signals a flexibility need via the digital trading platform SWITCH
- Providers who can adjust their production or consumption during the specified time window submit bids on the same platform
- The contract goes to the actor who submitted the lowest price per MWh of flexibility
- Producers, consumers, and energy storage actors with at least 0.1 MWh/h capacity located within the market area can participate as flexibility providers
Differentiation from consumption flex markets
A consumption-focused flexibility market addresses peak loads caused by high consumption. The Halland production-focused market addresses peak loads caused by high production — by reducing injection into the grid (downward regulation of production) or increasing withdrawal (increasing consumption). Both types contribute to faster grid connections.
No comparable market exists
As of July 2025, there is no other local flexibility market with a focus on production load in Sweden. The comparable national-level instruments are Svenska kraftnät’s balancing service markets for downward regulation (nedreglering).
Participants (named at launch)
| Participant | Role / quote |
|---|---|
| Falkenbergs Energi (Markus Bengtsson, tf vd) | Battery energy storage; “no doubt about the value of this pilot — batteries can help connect more production and more customers within existing infrastructure” |
| CheckWatt (Dan-Eric Archer, vd) | Aggregator/software; grid companies reporting increasing instances of high solar production combined with low consumption in local grids; using battery flexibility to reduce overload during peak production hours |
| Ntricity (Lars Skoglund, vd och grundare) | Multi-market optimization of flexible resources; contributing downward regulation of solar and wind production to smooth out production peaks |
| Varbergs Energi (Jens Nordberg, energihandelschef) | Flexible assets offering flex services locally behind meters and centrally to Svk; pilot “opens up regional flexibility” |
| Soltech Energy Solutions (Douglas Lindén, affärsområdeschef solparksutveckling) | Participating with solar park Solpark Öringe; pilot important for enabling new connections and illuminating value of inter-actor collaboration |
Relevance to wiki
- E.ON Energidistribution / SWITCH: extends the SWITCH platform and E.ON’s market operator role from consumption-side to production-side flexibility — an important expansion of scope
- Flexibility Market: first Swedish local flexibility market for production load; establishes that both sides of the generation-consumption balance can be procured locally
- Congestion Management: specifically addresses the summer overproduction problem — a different congestion mode than the winter consumption peaks that drive most existing flex markets
- Aggregation: CheckWatt, Ntricity, and Varbergs Energi are all aggregator-type actors; Soltech is a generator; Falkenbergs Energi is a battery storage operator — demonstrating the diverse resource mix
- Villkorade Avtal / connection speed: faster connection of production is cited as a key co-benefit of flexibility, consistent with E.ON’s general framing of flex as enabling connections
- Balancing Markets: Svk’s downward regulation markets are identified as the only comparable national instrument — positioning this local market as filling a gap below TSO level
