Where a battery earns, market by market

The homepage speaks in euros. This page speaks the market's language, for the reader who wants to know exactly which pools a battery can tap and why the balance between them is shifting.

THE VALUE POOLS

Six markets, three kinds of value

WHOLESALE

Day-ahead

Hourly auction, one day in advance. The frame for the day: charge in the trough, discharge into the peak.

WHOLESALE

Intraday

Continuous trading through the day itself. Where the frame gets refined as reality diverges from the forecast, hour by hour.

IMBALANCE

Imbalance

The settlement price for deviating from nomination. A risk to manage and, steered well, a source of value.

BALANCING

FCR

Frequency containment reserve. Fast, automatic frequency support, remunerated for availability.

BALANCING

aFFR

Automatic frequency restoration reserve. Activated by the TSO, remunerated for capacity and activation.

CAPACITY

CRM

The capacity remuneration mechanism: payment for being available when the system is tight.

THE DIRECTION OF TRAVEL

From ancillary services to wholesale

Batteries historically earned most on FCR and aFRR. That balance is shifting. Saturation pushes ancillary remuneration down as more batteries enter those markets, while a growing share of renewables makes wholesale prices more volatile, and volatility is exactly what a battery monetises. A strategy built for the coming years valorises across both, with wholesale as the growing leg.
