Missouri - Rolla (now known as Missouri University of Science and Technology). I have

12

been employed by OG&E for the last 23 years in several positions of increasing

13

responsibility including engineering, maintenance, and operations. I began my career with

14

OG&E in 2000 as a Process/Maintenance Engineer at the Horseshoe Lake and Mustang

15

Power Plants. In March of 2005, I moved to the Power Supply Services group as a Staff

16

Mechanical Engineer. In 2008, I became the Superintendent of Power Generation - Coal

17

at Sooner Power Plant. In February 2011, I became the Director of Redbud Power Plant,

18

and in October of 2017, Horseshoe Lake Power Plant was added to my responsibilities. In

19

February 2021, I transitioned into the role of Director of Power Supply Services.

20

In my current role, I am responsible for the operations and maintenance of

21

engineering functions and the management of capital projects for all of OG&E's thermal

22

generation fleet. In this role, I supervise a team of approximately 80 members including

23

engineers, project managers, and construction services personnel. In addition, I supervise

24

the asset condition monitoring organization that is accountable for the predictive

25

maintenance technologies OG&E deploys to monitor and analyze the condition of our

26

plants. I have worked at several OG&E Plants throughout my career either as a member

27

of the plant or as a Power Supply Services Engineer. Overall, my experience as an engineer

28

and leader at different levels throughout Power Supply has allowed me to become well

29

versed in the operations and maintenance needs of the OG&E fleet

OG&E'S GENERATION FLEET

13

Horseshoe Lake, Frontier, Muskogee (Unit 4 and 5), and Mustang are natural gas-fired

14

power plants. In addition, OG&E operates and is the majority owner of two combined

15

cycle gas-fired generation facilities: McClain and Redbud. Finally, OG&E owns and

16

operates approximately 450 MW of nameplate wind generation.

17

Table 1 below illustrates OG&E's generation resources, including the 2022 tested

18

capacity of each unit, and when those assets began commercial operation.

Q.

Does the MFR Package include information regarding OG&E's generation

7

availability and dispatch?

8

A.

Yes. I support Schedule G, which includes generator availability and dispatch during 2022.

9

Schedule G-1 contains a tabular summary of the monthly availability of each generating

10

unit, and Schedule G-4 contains a listing of all outages, derates, and an event description.

11

The monthly availability of the generating units is measured as the equivalent availability

12

factor ("EAF").

13

16

("NERC") in their Generating Availability Data System ("GADS") as the fraction of hours

17

the unit was available to produce electricity after all types of outages and deratings are

18

considered compared to the total period hours. The EAF metric is an appropriate measure

19

of a unit's ability to deliver its full output of energy for use by customers during a given

20

period. Capacity Factor is another metric that reflects output from specific units that is

21

driven by the Southwest Power Pool ("SPP") market dispatch instructions.1
