REV Renewables, NextEra, and CAIS Settle $67M Allegations Over BESS Market Infringements and Miscommunication.

REV Renewables, NextEra, and CAIS have settled allegations of CAIS BESS market infringements. The allegations stem from incorrect information CAIS received regarding the Vista Energy Storage project’s ability to provide ancillary services. The developer’s 40MW project provides CAIS with energy and ancilliary services. Developers receive a fee for their project being available to provide these services. CAIS will pay the developers for the charging/discharging of batteries to maintain specific charge levels. However, there was a conflict between the operation of regulation down and the ancilla service state of charge constraint, which sought to charge the battery. The settlement was part of a US$1 million civil penalty to the US Treasury and a larger US67 million to CAIS. Despite these violations, REV has denied any wrongdoing.
