What was the purpose and agenda of the 14th Biennial Transmission Workshop opening?

Vice Chair Walden 0:00

Good morning. Welcome to the 14th Biennial Transmission Workshop. I'm joined with Commissioner Marquez-Peterson and Commissioner Lopez, and Chair Myers and Commissioner Thompson will not be with us today, and they are excused. Let me do a quick sound check with the commissioners that are remote. If you want to check in and say hi, make sure that you're ready.

Commissioner Marquez-Peterson 0:30

Yes, good morning. Hopefully you can hear me okay.

Vice Chair Walden 0:32

We can hear you. Excellent. And Commissioner Lopez?

Vice Chair Walden 0:42

All right, we'll try again. Oh, yep. All right,

Commissioner Lopez 0:46

excellent. Good to go.

Vice Chair Walden 0:49

Good. I just want to make sure before we get started that we've got our commissioners online. So we'll start at the agenda opening comments. We will start with Commissioner Marquez-Peterson and then Commissioner Lopez.

Commissioner Marquez-Peterson 1:07

Great, thank you. I appreciate everyone preparing for today's meeting. I think the biennial transmission assessment is pretty important to Arizona, and it can assist us in regional coordination of transmission, particularly related to grid reliability during our periods of high peak, which we're having this summer, certainly, enable greater access to lower cost power from neighboring states, and increase our resiliency during extreme weather events. There are a lot of benefits to understanding exactly how transmission is occurring and the plans for proposed growth in the future. Today, I'd like the presenters to address, please, coordination among the utilities and their involvement in groups that I've heard related to planning, which is West Tech, Western Transmission Consortium,

Commissioner Marquez-Peterson 1:53

And also, many know that I've had an interest in the WEC planned facilities map, which is updated once a year. I'd like to also have each of the presenters speak to the WEC map and tell me how valuable that is and is it really impacting our regional planning. And I know the map currently presents tentative and committed projects. So I would like them to each please address those three groups as they present. But thank you again for the opportunity to make an opening comment.

Vice Chair Walden 2:24

Thank you commissioner Lopez.

Commissioner Lopez 2:29

Nothing more to add just the looking forward to the overall presentations and in previewing the the new maps that that were provided. I'm kind of looking to a deep dive so I'm looking forward to the meeting.

Vice Chair Walden 2:47

Thank you yes, I agree this is crucial for our reliability in the state and looking forward to what everyone has prepared for us. I will turn this over to staff for any opening comments and if you'd like we can have staff go ahead and present the or call up the presenters for each each one.

Adam Beckerman 3:13

Good morning, Vice Chair, Commissioners, and stakeholders. Adam Beckerman for Utilities Division staff. Welcome to the first workshop for the 14th Biennial Electric Transmission Assessment. Today, we will have presentations of 10-year plans from APCO, APS, SRP, and TEP and UNSC. TEP will also present the Southwest Area Transmission 10-year Snapchat Study. At the end of the workshop, staff will present a tentative schedule for the rest of the 14th VTA process. For those presenting virtually, staff will be controlling the slides, so please let staff know when to move to the next slide. After each presentation, we'll have time for commissioner questions. Thank you all for your participation in today's workshop, and we'll start with APS.

Adam Beckerman 4:06

Yeah, this is forward, backwards.

4:07

Oh, I can try. Yeah, okay. Great.

Matthew Robinson 4:12

Good morning, Vice Chair Walden, Commissioner, staff. My name is Matthew Robinson. I am the supervisor of transmission planning at APS. My team is responsible for performing the 10-year plan, the analysis behind it, the BTA, and the analysis behind these as well. So looking forward to presenting our presentation and answering any questions you may have. So an agenda of these slides is going to take a look at the 10-year plan for 2026 through 2035 that we've submitted, as well as our distributed generation and energy efficiency study that we performed, our extreme contingency study, as well as the reliability must-run analysis study that we've also performed. Going on to the next slide, we did perform a technical study as well to inform the 10-year plan itself.
