1 Q. Please describe the investments in metering
2 equipment the Company will be required to make prior to
3 participation in the western EIM.
4 A. The majority of the meters on Idaho Power's
5 generating units cannot provide the data granularity that
6 will be required for CAISO settlement purposes. The
7 Company will examine all existing meters and determine
8 whether or not they meet CAISO's requirement for providing
9 five-minute, 15-minute, or 60-minute data and update as
10 necessary. In addition, Idaho Power has identified a few
11 instrument transformers feeding these generation meters and
12 some instrument transformers at several power plant
13 locations that are not revenue quality and will need to be
14 replaced.
15 Q. Will revenue quality meters be required on
16 generation units that Idaho Power chooses not to be
17 available for dispatch in the western EIM?

Q.
No.
What is the Company's estimate of the total
20 costs of all required metering investments?
21 A. Idaho Power estimates investing approximately
22 $1.48 million in required metering equipment for
23 participation in the western EIM.

1 Q. Does the benefits study performed by E3 factor
2 in the costs Idaho Power expects to incur as a participant
3 in the western EIM?
4 A. No. Company witness Mr . Tatum has performed a
5 revenue requirement analysis that describes the net impact
6 of the upfront and ongoing costs and NPSE benefits
7 associated with participation in the western EIM and the
8 Company's proposed accounting treatment of those costs .

IV . CONCLUSION
Please summarize your testimony.
Idaho Power currently manages energy
imbalances within its BA . However, participation in the
13 western EIM to manage supply and demand could result in
14 lower costs due to the reduction in the need for reserves
15 and the efficient use of the transmission system, while
16 also helping to reduce carbon emissions and more
17 efficiently use and integrate intermittent renewable
18 energy. Absent Idaho Power's participation in the western
19 EIM, market liquidity in the bilateral real - time market
20 will likely continue to decline and additional reserves
21 will likely need to be maintained, resulting in increased
22 NPSE for the Company's customers. It is estimated that
23 Idaho Power's participation in the western EIM would result
24 in sub-hourly dispatch cost savings of $4.1 - $5.1 million

A. No . Yes. Even though Idaho Power will identify
which Company owned generating units will be considered
participating units and available for dispatch in the
market and which will be non participating units , CAISO
requires that both are able to provide interval data but at
different levels of granularity .
Q. What is the Company's estimate of the total
25 costs of all required metering investments?
