BESS Benchmarking
At KYOS, we help investors, developers, and operators in the rapidly evolving battery energy storage (BESS) market with actionable insights and robust analytics. Our Battery Index is part of a broader suite of advanced benchmarking and valuation tools designed to assess revenue potential and performance across markets and technologies.
KYOS Battery Index
The KYOS Battery Index reports cashflows in a specific past month for the defined battery and market. The index is expressed in kEUR/MW/year.
The modelled battery is a 10MW/40MWh BESS, with roundtrip efficiency of 88%, and 1.33 max cycles/day. The BESS is optimized in wholesale markets (Day-ahead and Continuous Intraday) and balancing markets (aFRR, including free energy bids).
For comparison, we added a TB4 market reference. TB4 is defined as top–bottom spreads between the 4 highest vs lowest day-ahead market prices. It is as a conservative metric of value captured by a 4-hour BESS
