CLARKSON: Mr. Lee, I'd like to, if I can ask a question here—excuse my voice. I'd like to
<br />zero in on what you consider to be normal operations. It would be my belief, and correct me if
<br />I'm wrong, that this plant would be subject to dispatch by HELLO, that they would be able to
<br />specify the load at which you operate and when and how long you operate. Is that correct?
<br />LEE: Yes, we will be under the energy management system dispatch from the Hawaii Electric
<br />Light Company.
<br />CLARKSON: And, wouldn't you consider that to be normal operation to be operating under
<br />dispatch?
<br />LEE: That is normal operations, yes.
<br />CLARKSON: Well, then, I, I don't understand why a planned shutdown and planned startup for
<br />maintenance would not be considered normal operations. I can, I can easily see how a plant trip
<br />a turbine trip, a grid disruption would result in an emergency and the abnormal operation, but in
<br />my understanding, a planned shutdown and a planned startup, I would think one would consider
<br />that to be normal operation.
<br />LEE: Normal routine maintenance shutdowns are planned, so it could be considered a normal
<br />operation, but not, let's say, it doesn't, if it's a turbine outage, turbine planned maintenance
<br />outage, or a steam boiler outage, there are durations that could vary. So, and, mostly in the terms
<br />that we use "normal" would be in the sense of operations 24/7, yeah, that's the context we've
<br />been using it in. Although, from a plant maintenance standpoint, having normal maintenance is
<br />normal, and you have different degrees or different levels of maintenance. So, it could be that a
<br />turbine maintenance outage is not going to occur every year; it's going to occur maybe every six
<br />years or, and so on. A boiler maintenance outage, depending on the boiler, how it operates and
<br />how it's dispatched, based on the readings we get, there may have to be boiler maintenance
<br />outages maybe once a year or maybe twice a year, but you know, the variate, the time in which
<br />the unit is down for maintenance depends on what needs to be done, you know.
<br />CLARKSON: One more question for me, and I'll turn it over to the rest of the Commission.
<br />Does the, I assume the plant is going to have a black start diesel generator available?
<br />LEE: Yes, the unit will have a black start biodiesel generator.
<br />CALRKSON: Okay, biodiesel generator, and this would be used only under conditions when the
<br />grid was not available. I understand that that's what black start means is when you have a dead
<br />grid and you have to start up the plant without it. Will not that diesel exceed 55 dBA when it's
<br />in operation?
<br />LEE: Our plan is that whatever the noise source emitters are, we plan to mitigate that with our
<br />noise mitigation plan, either through insulation, landscaping, different methods. We are
<br />spending quite a few dollars in the design phase and the construction to, the plan is to mitigate to
