Pexapark, a Switzerland-based energy market analytics firm, has reported revenue potential for solar assets in Germany’s aFRR capacity market. The analysis has stated that solar assets could earn up to 7% above day-ahead revenues through aFRR participation. The source states that solar assets first entered Germany’s aFRR market in November 2025. Solar assets bidding 25% of minimum expected generation could have captured around 6% additional revenue during 2025. Including upward aFRR capacity raises the estimated uplift to approximately 7%. Downward aFRR prices between 12:00 and 16:00 averaged 48.4 EUR/MW/h (~ $56.63/MW/h) during 2025. The analysis explicitly states that most solar aFRR revenue potential occurs between May and September, with little to no uplift during winter months. Hydropower accounted for around 17 GW of 25 GW prequalified capacity as of March 2025, while bess capacity expanded to about 550 MW. Pexapark has noted that rising competition may reduce future revenue potential.
