Warning: 1.58 cycles/day (577 cycles/year) exceeds warranty limits for many BESS installations. While some systems can accommodate higher cycling, many warranties are limited to 365 cycles/year.
2The PortfolioEnergy virtual BESS used approximately 1 cycle per day at a round-trip efficiency of 90%. Computed using a backtest with optimisation using Montel forecasts and EPEX order book data. Auctions cleared with settled prices. Intraday continuous trading was simulated by introducing a multi-second delay (order book time) between accessing the order book and matching orders. Iceberg orders and user-defined blocks were not considered.
