Selling Power to the Utility

Questions & Answers

We believe that one of the main drivers of success of the competitive bidding process is to ensure transparency in that process. We believe that seeking the input of stakeholders and working collaboratively with such stakeholders to refine and improve the process will lead to successful RFPs.

We hope that the following answers to stakeholder questions will be helpful to potential Proposers and others interested in our RFPs. In order to ensure that information provided by the Companies is shared fairly with all Proposers, we are utilizing this page as a repository for questions and answers. While we aim to provide answers to all questions asked, it may not be feasible to respond directly to each question or comment submitted. Instead, similar questions may be consolidated so as to provide more helpful information. Questions specific to a particular project that might give a competitive advantage or contain confidential information may not be answered here or may be reframed in such a way as to be made available to the general public. Questions not relevant to these RFPs or questions received late in the process which do not allow for the Companies to provide an adequate answer may also not be answered here.



Could you please confirm whether the Company-owned Kahe Site is limited to 9.5 acres or whether a larger acreage can be assumed, if necessary, for the Project?


The Company is open to offering more land adjacent to the outlined area of the Company-owned Kahe Site. However, the land beyond this outlined area is significantly sloped and may not be suitable for siting project facilities. We are also not offering land on other portions of the Company property not directly adjacent to the Kahe Site.


Is the PowerAdvocate Proposal submission for variations different than in Stage 1?


Yes, the submission process for Stage 2 is different from Stage 1. In Stage 1, each proposal variation required a Proposer to create separate and distinct user names and submit each proposal variation separately under different user names. In Stage 2, Proposers may submit a Proposal with up to four variations (variations of pricing terms, Facility size, with/without storage, differing levels of grid-charging capabilities) under one user name. All variations within a Proposal must be proposed on the same site and use the same generation technology to be considered the same Proposal (under the same Proposal Fee). See RFP Section 1.8 and RFP Appendix B, Sections 1.1, 2.0, and 3.0.

Note for Oahu/Hawaii Island:
For each of the four variations, an additional variation with Contingency Storage may be proposed if the only change is the addition of a Contingency Storage component. Thus, potentially up to eight variations (four variations without Contingency Storage, and four mirrored variations with Contingency Storage) can be submitted under one user name and one Proposal Fee.


Can we connect a project to an existing 138 kV substation?


Standalone Storage projects (with or without Contingency Storage) and Paired projects (intended to meet the Storage Requirement (as such term is defined in the RFP) and/or Contingency Storage) will only be allowed to interconnect to the offered 138 kV substations, and interconnection into other existing substations will not be considered for this RFP. Generation only projects or Paired projects (not intended to meet the Storage Requirement and/or Contingency Storage) may be allowed to interconnect to existing substations. See Section 3.11.3 of the RFP.


In section 2.13 Experience and Qualifications of RFP Appendix B, it is requested that we provide evidence that project participants have worked jointly on other projects. Could you provide an example of how to fill in the table that’s provided in the section or advise if a modified format would be acceptable?


Please use the table format as instructed in RFP Appendix B section 2.13.1. The intent of this table is for bidders to clarify who on their team meets each of the experience categories below and the relevant projects or projects they worked on that best showcases their related experience. An individual or entity can meet one or more experience categories. A general example on how to fill out this table is provided below for reference.


Where should we send questions regarding the RFP, interconnection, or the process to?


The Independent Observer for this RFP has requested that all communication going forward be channeled through the PowerAdvocate Messaging function (Electronic Procurement Platform) instead of via the RFP Email Address. If you have not done so already, please register as a PowerAdvocate Supplier and email to the RFP Email Address your Company Name and username. You will then be added as a Supplier to PowerAdvocate RFP event. Once allowed into the Event, all communication and responses to questions will be conducted through the PowerAdvocate Messaging function/tab.


Does the Certificate of Good Standing and the Federal and State tax clearance certificates need to be dated within a certain period of time to be valid for this Stage 2 RFP?


Yes, the Certificate of Good Standing from the State of Hawaii Department of Commerce and Consumer Affairs and Federal and State tax clearance certificates must be dated within 60 days of the date of your proposal submission. Also, a Certificate of Vendor Compliance issued from the Hawaii Compliance Express (HCE) eliminates the need to obtain both a Certificate of Good Standing and Federal and State tax clearance certificates, and will be accepted in your Proposal submission in lieu of those. The Certificate of Vendor Compliance must also be issued within 60 days of the date of your proposal submission.


In the Oahu RFP, does the 200 MW mentioned in the introduction refers to the maximum amount of storage you are looking?


Specific to Oahu, the 200 MW mentioned in the Introduction is not a maximum amount, and instead refers specifically to the amount of MW capacity sought in the Oahu RFP to replace the capacity from an existing firm generator, which the RFP refers to as the “Storage Requirement”. With regards to the Storage Requirement, the RFP specifically provides, “The total amount of energy storage being solicited in this RFP is the capability to store and discharge energy equivalent to at least 1,200 MWh per cycle via a total nameplate capacity of at least 200 megawatts (“MW”). This MW and MWh storage capability is referred to herein as the “Storage Requirement”.” The Companies are also seeking renewable energy generation projects paired with storage not intending to meet the requirements of the RFP Storage Requirement. The storage from these paired projects would be above and beyond the Storage Requirement being sought and there is no specific target for this storage. Selection would be dependent on evaluation and benefit cost analysis of proposed projects with storage and proposed projects without paired storage competing to meet the variable renewable dispatchable generation MWh solicited in the Oahu RFP.


For the Oahu RFP, can you please describe what is meant for a Project to be black start capable?


Black start capability for Oahu is not a requirement for projects being proposed but a preference for standalone energy storage projects or energy storage paired with generation facilities. If a Project is not already designed to be black start capable, the RFP asks to specify the cost to enable back start. The Company would expect a Project providing black start on Oahu to have the ability to provide power to the Company’s grid without relying on any services or energy from the Company’s grid to recover from a total or partial shutdown. When the Company’s grid blacks out, the Project may experience during start-up (if the Project remains connected) or while connecting, step changes in load and other transient and dynamic conditions as it picks up load without support from other resources on the system. If the project wants to be considered as a black start resource, the PSCAD and PSSE models provided in the time required under the PPA would need to be able to model the black start capability. Other than as mentioned, the Company has not at this time designed requirements for the black start capability and are looking to Proposers to explain how their solution will provide the service and the functionality their design can provide.


For the Oahu RFP, how many inverters out of the total will need to have black start capability?


100% of the inverters is preferred to allow the storage to run at full capacity unless some inverters can operate in grid following mode while other inverters run in black start/grid forming mode.


For the Oahu RFP, are there requirements on how the inverters are supposed to switch from normal operation to black start?


If the Company’s grid blacks out and the Project’s facility shuts down, the Company wants the facility to transition to and start in black start mode. Transition from black start back to normal is preferred to be online, bumpless, and seamless.


A Proposer states they are currently not registered in the State of Hawaii, and asks if they can state in the Proposal that they will provide the Certificate of Good Standing and the requested tax clearances if their proposal is ultimately selected as a winning proposal. Will that meet the RFP eligibility requirements?


No, the Eligibility Requirements for this RFPs specify that the Proposer must provide as part of its Proposal submission, a Certificate of Good Standing from the State of Hawaii Department of Commerce and Consumer Affairs and federal and state tax clearance certificates for the Proposer. Please also note that the Company's response (R6) in the Q&A section of the RFP Website states that a Certificate of Vendor Compliance issued from the Hawaii Compliance Express will be accepted in lieu of these required items.


Is a Project required to be located outside of the Extreme Tsunami Evacuation Zone?


No, Project infrastructure does not need to be located outside of the Extreme Tsunami Evacuation Zone. Refer to Section 1.2.5 in the Oahu and Maui RFPs, and 1.2.6 in the Hawaii RFP for tsunami-related requirements.
