Is Intraday the real hedge against saturation in ancillary services markets?

In the S2 2025 Finland Price forecasts, Clean Horizon believes that Intraday takes a significant share of the revenues.

But a key question remains:
Why wouldn’t Intraday also face BESS saturation, just like reserve markets?

At Clean Horizon, we believe Intraday opportunities will continue to grow, driven by increasing exchanged volumes on the continuous market.

Focus on the Finnish Intraday Market

Let’s take a closer look at what’s actually happening on the Finnish Nord Pool Intraday continuous market. Intraday markets represent the ultimate market for generators and consumers to settle their position before delivery.

• Shift to 15-minute products
  Since the transition to 15-minute products on March 18th, 2025, the number of transactions has exploded.
  December 2025 recorded 6× more transactions than December 2024.
  
• Strong correlation with renewable generation 
  Exchanged volumes are tightly linked to renewable production. Over time, intraday continuous volumes have grown steadily, in line with the rise of renewables.
  This correlation is also clearly visible on a monthly basis, as shown by 2024 data.
• What does this mean for BESS?
  As batteries increasingly enter the intraday market, they will naturally capture the highest-value transactions, while lower-value trades are left for other assets.

However, the continuous growth in traded volumes acts as a hedge against market saturation, sustaining long-term intraday value for BESS.
