BESS operating modes

How BESS can operate

A grid-connected BESS can work in several operating modes. The most valuable strategy is usually a combination of energy trading, balancing markets, and local grid or site value, depending on market access and technical qualification.

Nord Pool price arbitrage

The battery charges during lower-price hours in the Latvian bidding zone and discharges when the price spread is high enough to cover losses, grid fees, battery degradation, and trading costs.

Frequency reserves

A qualified BESS can reserve fast capacity for FCR, aFRR, or mFRR products, helping the power system maintain balance and earning capacity payments when bids are accepted.

Balancing activation

When the transmission system needs energy up or down, the battery can be activated to inject or absorb power. This can create activation revenue in addition to capacity revenue.

Local grid and site value

Storage can reduce peak loads, support local resilience, and make better use of existing connection capacity, which is especially useful where network capacity is limited.
