The negative-price, curtailment and grid-fee rules that drive Serbia's battery economics.
We compute it for every ≥1 MW battery — independent, from public data.
Stromfee provides specialized expertise in BESS integration within complex energy markets. By analyzing TSO and day-ahead market structures, we help operators navigate regional grid dynamics. Our focus remains on optimizing battery storage performance to meet local demand. We provide the technical insights necessary for successful project deployment.
Stromfee leverages significant price spreads in day-ahead markets to maximize BESS profitability. For example, in Slovenia, the day-ahead price spread reached an average of EUR 170/MWh over a 30-day period. This represents a substantial opportunity for arbitrage strategies. Our team understands how these fluctuations impact storage operations.
Stromfee identifies concrete funding opportunities, such as the EU-approved storage support in Slovenia. This includes a EUR 10 million corporate call from the Climate Change Fund administered by the market operator. We help clients navigate these specific financial instruments to secure project viability. Our goal is to align your BESS assets with available regional incentives.
