Why cannot I add/delete more generating units under my aggregation? Any pending invoices will prevent account holders from adding/removing more generating unit under your aggregation. Pay the invoice and you will be able to add/delete generating units.
What does suspend certificate mode mean? An asset that is approved may have their status updated to "Suspend Certificate" mode. Aggregated assets are likely to be in the suspend certificate mode since account holders will add more generating units to the aggregation. Under this mode, you cannot issue certificate until it is in "approved" status. Please reach out to the TIGRS administrator requesting for reapproval of your asset if in "suspend certificate mode."
