Every month, Svenska kraftnät - the Swedish national grid operator - publishes updates on balancing services like FCR. These services help keep the electricity grid stable, especially when supply and demand don’t match. Here's a quick overview of what happened in April 2025 on the FCR markets.
What is FCR?
FCR stands for Frequency Containment Reserve*. It's used to quickly correct any imbalances in the power system. There are three types:
-
FCR-N (Normal)**: Keeps the frequency stable during normal operations.
-
FCR-D up: Adds electricity to the grid when frequency drops.
-
FCR-D down: Removes electricity when frequency is too high.
**Key Highlights for April
-
Prices increased** for all three FCR services compared to earlier this year.
-
However, prices are still lower than April 2024, especially for FCR-D products.
-
FCR-N averaged 37.4 EUR/MW - the highest monthly average in 2025 so far.
-
FCR-D up averaged 8.91 EUR/MW, and FCR-D down averaged 11.38 EUR/MW.
-
FCR-D down had very large price swings, from as low as 1.38 EUR/MW up to 773.71 EUR/MW during one peak on April 27.
**Why are prices changing?
-
A higher demand** for reserve power was introduced starting January 2025 - especially for FCR-D down. This added more volume to the market.
-
More battery storage systems have joined the market, increasing competition.
-
Water flow from melting snow (spring flood) affects hydropower, which also impacts FCR prices.
-
The new pay-as-cleared pricing model (used since February 2024) may lead to higher or more volatile prices compared to the older pay-as-bid system.
**Regional Trends
-
Southern Sweden (SE3 and SE4) is now more active** in the FCR markets, compared to the north (SE1 and SE2), which used to dominate.
-
The shift is driven by new participants - particularly battery systems - entering the market in the south.
**Supply Update
As of April 1, 2025:
-
Battery capacity qualified for FCR-N** increased by 30% since January.
-
Battery capacity for FCR-D up** rose from 610 MW to 670 MW.
-
Flexible consumption is growing slowly, but still plays a small role in the market.
