Q2:

What is the single point of failure requirement?

No single point of failure from the Facility shall result in a decrease in net electrical output greater than a nominal 3.3 MW AC. Additionally, in meeting this requirement, the Facility must be segmented in equally sized capacities (MW). Projects larger than 3.3 MW, will require at least two (2) points of interconnection. There is room for up to four (4) points of interconnection in the existing switchgear enclosure.

Q3:

Is there a black start requirement?

Black start capability is preferred. Proposals will need to identify any incremental costs to enable their facility to be black start capable, if not already enabled.

Q4:

A breaker and a half scheme was required in the Maui Stage 2 RFP. Does Maui Electric require the same scheme for the Lanai RFP?

A breaker and a half scheme is not required for the Lanai RFP. Refer to Appendix H for Interconnection Facilities and Cost Information.

Q5:

What is the zoning of this area?

The State Land Use and the County Land Use maps classify this parcel as Agricultural.

Q6:

Is this the only site available for this RFP?

Yes, it is.

Q7:

Is the battery fully dispatchable on a daily basis?

The RDG PPA specifies that the BESS shall be designed for an average annual use of 365 cycle(s) (a cycle is a discharge equal to the BESS Contract Capacity, and sufficient charging to return the BESS to 100% State of Charge).

Q8:

What is the throughput ratio of the system?

The Company is looking for the nominal MWh as indicated in the RFP at the point of interconnection, and any losses and system derates must be considered on the developer's side.

Q9:

Where would the system metering be located at the point of interconnection?

The metering would be located on the developer's side, just outside of the Company's baseyard. The Company's existing switchgear PTs and CTs shall not be used for metering the IPP.

Q10:

Is there a minimum power requirement or just minimum energy?

The only reference to minimum power is the 3.3 MW AC single point of failure requirement.

Q11:

There is a structure that is exposed above ground that resembles a valve. What is its purpose?

The Company does not have information on the existing conditions or infrastructure on the Pulama Site. Potentially historically significant objects have been noted and described in the Archaeological Literature Review and Field Inspection Report for the Pulama Site.

Q12:

How big are the existing generators?

There are six (6) generators that each have 1 MW capacity and two (2) Caterpillar units that each have 2.2 MW capacity.

Q13:

What is the preferred path for interconnection to the existing switchgear?

While possible, an overhead interconnection would be difficult given the existing facilities. An underground interconnection from the Facility to the existing manhole and then from the manhole through the existing conduits to the stub outs at the switchgear.

Q14:

Is there an underground mesh or grounding grid in the path of the new proposed underground?

Depending on the underground route, the existing underground conditions may differ. In general, the developer will be responsible to restore or replace any grounding infrastructure that is disturbed in accordance with Company specifications.

Q15:

Does the Company own the property to the southeast of the Miki Basin facility?

No, Pulama Lanai owns the adjacent property. The Company owns the property where the proposed interconnection is anticipated, but the property line is not currently not marked. The property line shall be staked and marked prior to construction.

Q16:

Is there an option to tie into the existing overhead lines?

The preferred method of interconnection is through the existing stub-outs at the switchgear. Developers who intend to propose an alternative interconnection are encouraged to contact the Company with their questions through PowerAdvocate.
