CAISO submitted a tariff amendment to remove language in the CAISO tariff that states non-generator resources with resource adequacy capacity have a requirement to submit $0/MW availability bids in the residual unit commitment (RUC) process. CAISO explains this language is not consistent with the CAISO's current practices, which do not support the submission of RUC availability bids by non-generator resources.
