Hemingway POR/POD
Effective June 1, 2012, Idaho Power introduced a new POR/POD of HMWY into its system. As far as
the POD, this is just a replacement of the prior M500 point that Idaho Power sold to for many years.
However, this is a new POR to our system. HMWY is another interconnection point with PacifiCorp on
the western side of Idaho Power’s system. Although ENPR and HMWY are separate POR’s, there is a
simultaneous limit applied to the POR’s. The TTC for the combined paths from a west to east direction
is as follows (this is the TTC value that corresponds with the HMWYENPR-Northwest internal segment
point reflected on the Idaho Power OASIS map):
Winter Operations (November 1 – March 31) - combined TTC of 400MW
Spring Operations (April 1 – May 31) – combined TTC of 450MW
Summer Operations (June 1 – October 31) – Combined TTC of 510MW
The POR of ENPR has a TTC of 400MW and the POR of HMWY has the profiled TTC reflected above.
However, on a combined basis, they cannot exceed the profiled TTC above.
What this means is on a firm basis, the combined total of transmission sold west-east across Idaho from
the POR of ENPR and HMWY combined will not exceed the above TTC values. As with all paths on
our system, non-firm ATC will be impacted by any counter-schedules (refer to Idaho Power’s ATC ID
for non-firm calculation).
Also note, both have a direct correlation to Path 14, Idaho Power’s Idaho-Northwest path.
