NEW IID OPEN ACCESS SAME TIME INFORMATION SYSTEM (OASIS)
Imperial Irrigation District is pleased to announce that, in an effort
to obtain a more efficient and simplified webTrans and webOASIS system,
it is in the final stages of modifying its current OASIS. As part of the
reconfiguration, IID has created individual sources for each Independent
Power Producer in its Balancing Authority Area, thereby reducing the number
of Point of Receipt/Point of Delivery combinations, and also reducing the
number of transmission paths. The new system will allow IID to monitor
and maintain its webRegistry (NAESB) in a more efficient manner.
Starting July 7, 2014, each Transmission Service Request (TSR) that is
in “STUDY” mode will be individually transitioned from the old system to
the new. Please be assured that all customers will retain their current
queue position(s). Each customer will be required to electronically submit
a new Transmission Service Reservation. The new TSR will reference the
old OASIS “AREF” number so there is a clear history in the system. This
will be achieved by inserting a short statement into the “Customer Comment”
section specifying the new reservation is being submitted for the purpose
of replacing the old OASIS reservation. There will be an interim period
of parallel operation with both the old and new TSRs active in the production
system. This interim period will allow for quality assurance during transition.
PLEASE NOTEthat beginning immediately, for those intertie points with
Available Transfer Capability (ATC) where service can commence immediately
with no additional analysis, IID will begin tendering Transmission Service
Agreements in accordance with the provisions of Section 17 of the Open
Access Transmission Tariff.
IID will be sending such Agreements for execution in queue order. Customers
will have fifteen (15) calendar days to sign and return the agreement(s)
and begin paying for reserved capacity or their transmission service request
will be deemed terminated and withdrawn.IID will proceed to refund
any pending reserved capacity deposit for terminated/withdrawn requests.
Following termination or withdrawal, IID will make remaining capacity
available to the next eligible customer in the queue on a first-come, first-served
basis. Customers may voluntarily withdraw transmission service requests
by contacting IID’s OASIS Administrator at
As the new system is being configured in OATI production system, new e-tag
templates that include newly created Sources, Paths, and TSR numbers will
be distributed to pertaining PSEs. Once the new system has been set-up
in its entirety, an announcement will be posted on IID’s OASIS page stating
the revamp has been completed. IID will also notify customers via email.
Due to the implementation of the NERC ATC-related MOD Standards, TTC (and
ATC) values posted after April 1, 2011 are under review and subject to
IID will work closely with customers to ensure a smooth transition to
the new OASIS. Questions regarding the process should be referred to Jerrod
Sweet, IID’s Open Access Same Time Information System Administrator, via
