The value proposition of battery storage extends far beyond mere wholesale energy arbitrage. To truly unlock the full economic potential of these assets and maximize their contribution to grid stability, it is crucial to consider their participation in ancillary services markets. We show this multi-market optimization here by way of example focusing on all spot markets (Day-Ahead, Intraday and Intraday Continuous) as well as the ancillary services.
Over the last year we became increasingly involved with the “science” of modelling past and future revenues of battery energy storage systems (BESS) and now decided to shed some light on this practice. We believe that customers are being sold a lot of voodoo for science and that the incentives in this industry are not at all well aligned.
We are often asked how the financial optimization (or: arbitrage) of a battery across the different market places of the spot market works. We show this x-market optimization here by way of example focusing on the day-ahead spot market (hourly auction at 12 noon), intraday quarter-hourly auction (at 3 p.m.) and the so-called intraday continuous market (quarter-hourly products up to five minutes before delivery).
