Greece has one of the most attractive day-ahead market spreads in Europe, with near-zero prices during midday RES oversupply and often extremely high evening peak prices. This creates ideal arbitrage conditions for BESS operators.
The ancillary services market is relatively unsaturated, with limited participants and consistently elevated prices. This provides BESS assets with an opportunity to capture significant revenue streams before competition increases.
The Greek TSO has a conservative approach to system balancing, resulting in frequent activations and strong demand for flexibility. BESS is uniquely positioned to provide these services efficiently and profitably.
