Brandt looks into when ERCOT''s Ancillary Services will be saturated for BESS. Once there is more battery energy storage capacity being bid into Ancillary Services than there is capacity to be awarded, prices start to fall - due to this increased competition. This is known as ''saturation''. This makes Ancillary Services much less …
