Sweden
Overview
Sweden’s frequency and balancing products are broadly in-line with the Nordic cooperation model. FCR-D and aFRR are particularly well-suited to DERs due to small minimum bids, asymmetric acceptance, and flexible prequalification. Strict measurement rules require a wallbox connection for EV flexibility. In 2022, these products were typically more lucrative than in neighboring countries.
SVK, Sweden’s TSO, allows small (<0.1MW) assets to be type-qualified and therefore assed to a pool without pre-qualification. Although this type qualification is limited to 1MW of additional capacity, the relatively quick (<8 week) pre-qualification process means this isn’t an insurmountable barrier.
The BSP role is not yet active is Sweden, unlike neighboring countries, limiting participation to BRPs.
