Arbitrage shapes the future of battery revenues: capacity market and bankability
AleaSoft Energy Forecasting, September 18, 2026. The rapid growth of storage will progressively transform battery revenue streams in Spain. Balancing services offer highly attractive opportunities today, but their capacity is limited. In the long term, energy arbitrage is emerging as the main revenue base for these assets, now complemented by the new capacity market. Webinar […]
Intraday spreads at 2026 highs: how much battery storage actually captures
AleaSoft Energy Forecasting, September 15, 2026. The Spanish electricity market’s one-hour intraday spread reached an average of €195.29/MWh in August 2026, the highest monthly level of the year, compared with an average of €121.78/MWh so far in 2026. This context widens the opportunities for battery storage, but the intraday spread is only the starting point […]
