VITOUSEK: Yes DEFRANCO: Is there off-the-grid options now to charging butteries like solar? MORIN: Yeah, so the charging systems need access to energy, and there is the option to, you know, plug into the grid, which is the most common, but there are also the options for microgrids or for—and there is actually a good example at the community college here in Hilo where you've got a solar canopy, so it's a solar panel array, that tracks the sun. There is a battery system that's hooked up to it, and you can actually charge your car there. So that system is totally grid independent. So there are those solutions as well. I will say that they are more costly because you now have the need for, you know, the equipment and the batteries, but they may also be an acceptable solution where there is no infrastructure. So thinking about, you know, up on Saddle Road, for example, that might be ideal where you've got a lot of sun and you don't have the grid infrastructure required for charging, you can pop those up there and that could also work. So it's just one additional type of solution that we can avail of. KIMBALL: And I should mention that the charger that is associated with that solar canopy is the same charger that you'll see in the parking lot at Walmart hooked up to the grid. It's the identical technology. VITOUSEK: Okay. So it was Recommendation 8 on clarifying the conflict between number of parking stalls required for each EV versus each plug on an EV charger. And what was the resolution to that, that was recommended? KIMBALL: So what, yeah, so just—I'm sorry, am I interrupting? Go ahead, Director or KAY: Oh, no, I was this is ChristianI was just going to address that. Yeah, so there was a clarification that it's number of plugs per parking space, not number of chargers per parking space. And I think I understand your question maybe as, if there are multiple plug options on a single charger, but there's maybe only two power lines going to juice those plugs VITOUSEK: Correct. KAY: you want the number of lines to be the ability to charge the number of vehicles that come out of the charger, not the number of possible plug-ups. So it's a semantic thing that I'm seeing. So VITOUSEK: Yeah. KAY: so that's what you want to clarify. Did you hear that, Councilmember Kimball? KIMBALL: I did, and I'll have to think about the language of that. So, I mean, the typical development for the infrastructure would be you would have one line coming from wherever your power box is and then out to the charging location, and then you could have multiple chargers at that location. And some chargers, like you mentioned, have more than one plug. So, 19 EXHIBIT B
