Green Energy Storage: Co-located BESS with PV & Wind — incl. EEG direct marketing

This analysis examines co-located battery storage (BESS) combined with PV or wind plants in the German market with EEG direct marketing. Revenues are derived from FCR, aFRR, day-ahead/intraday arbitrage, and the EEG sliding market premium model. Both scenarios show a significant IRR uplift compared to the respective reference case without BESS — wind projects benefit more due to double the full-load hours.
