Frequently asked questions

Can you perform CA-ISO Compliance for a new facility ?

Yes. We have CAISO Authorized Metering Inspectors, technical resources, and the equipment necessary to complete the inspection and certification CAISO requires of new and existing CAISO Metered Entities.

Do you take care of the CA-ISO coordinating and procedure?

Yes, to the extent we are allowed under current CAISO rules, the owner opens a maintenance project in the CAISO portal called RIMMS, and AMPS DMS provides the maintenance services identified in the outage (OMS) on the devices identified by CAISO EDAS. We find that some customers may want us to take care of all of the CAISO coordination, including compliance paperwork. We also find that other customers have a group that takes care of this CAISO coordination for them. We will be glad to assist you with all of the coordination efforts we are allowed to provide on your behalf.
