Pacific Energy Corporation inquiry dated 11/28/17: QUESTION:

Buy American Act

3. Will ALL products need to conform to the Buy American Act? Or only major items? ANSWER:

The Buy American Act applies only to photovoltaic devices. QUESTION: 5. There has been evidence to show that in other federal procurement, Buy American Act is waived

for certain conditions. For example, as below from the Federal Transit Administration (FTA):


“FTA may waive Buy American if FTA finds that: (1) application of Buy American is inconsistent with the public interest; (2) the steel, iron, and goods produced in the U.S. are not produced in a sufficient and reasonably available amount or are not of a satisfactory quality; or (3) including domestic material will increase the cost of the overall project by more than 25 percent for rolling stock. The process for seeking a waiver is set forth in 49 CFR part 661.” Referred from below website: https://www.transit.dot.gov/buyamerica

Will GPA allows such type of exemptions as long as the consortium? ANSWER: The DON does not intend to issue waivers from this requirement. LSIS inquiry dated 12/05/17: QUESTION: 1. I am working at LSIS in Korea, which does manufacture for PV inverter and ESS; and now our

company is preparing this Mult-Step bid “Renewable Energy Resource Phase III”.

Can we use our Korean PV inverter and ESS PCS, which are made in China for this project? ANSWER: The Buy American Act applies only to photovoltaic devices. Wartsila inquiry dated 12/09/17: QUESTION: 1. I have a question about confirming receipt of Amendments. Is it necessary to sign each

Amendment and return a signed copy to you or is an email confirming receipt sufficient? ANSWER: Refer to Page 15 of 501, Section 2.3 IFB Amendment. QUESTION: 2. Also, if the bidder is a partnership, Joint Venture, consortium, or other form of joint bid, is it

necessary for both entities to formally register as a potential bidder or is it sufficient if only one of the companies registers?

ANSWER: It is at the discretion of the companies of the partnership, joint venture, consortium, or other form of

joint bid. However, the primary bidder shall be identified on the Bidders Register. Siemens Industry Inc. inquiry dated 12/16/17: QUESTION: 1. Can GPA provide a technical description or stability study bode diagram explaining why ramp rate

control of 1% for both PV and energy storage is a requirement of the RFP? ANSWER: Response shall be forthcoming.

Buy American Act

➢ Buy American Act The IRB on P10 of 512 indicates ‘The renewable resources shall conform to the Buy American Act for projects located on federal lands’. The Buy American Act does not always show clearly from which maker(s) of PV panels, invertors, and energy storage system CONTRACTOR can procure. Do the following cases conform to the Buy American Act? 1 CONTRACTOR procures the PV panels made in China. 2 CONTRACTOR procures the PV panels made in US and the panel’s maker has its head quarter in China. 3 CONTRACTOR procures the PV panels made in Malaysia and the panel’s maker has its head quarter in China.

Response forthcoming.

1 Overview ➢ maximum export capacity 30 MW The IFB on P52 of 512 indicates ‘The Bidder’s renewable resource project shall have a maximum export capacity 30 MW (AC) at the interconnection point; this may be the combination of several generation units at one site.’ I would like to ask you the bidder may propose the PV power development at Site No. 5 of 18 MW only.

The output capacity for projects that are exporting from the ESS may be larger than the PV System depending on the ESS inverter capability. This establishes a limit that bidders cannot exceed due to system stability issues.

3 Page 52 of 501

1. Overview

The IFB on P52 of 512 indicates as follows; 5. The ESS must provide the following functions: o The primary purpose of the ESS shall be for energy shifting which is to deliver the solar produced energy at another time or period of the day. The above description of required functions to ESS is not always clear. The other function which is noted as ‘the renewable generation ramp limit shall be 1% of the project nameplate capacity per minute’ is clear. I would like to ask you to show the numerical description of ‘energy shift’ requirements.

The primary purpose of the ESS shall be for energy shifting which is to deliver the solar produced energy at another time or period of the day. All energy delivered must be through the ESS which shall deliver energy at a firm output. GPA will dispatch energy accordingly based on the project’s maximum export capacity, stored energy and GPA’s needs.

Article 8 Alternation

The IFB on P146 of 512 indicates as follows; ➢ In particular, (COMPANY) shall comply with all requirements as provided in Section 4.2, Section 7.2 and Section 8 of the Master Lease and as specified here I would like to ask you to show Section 4.2, Section 7.2 and Section 8 of the Master Lease.



5 The IFB on P146 of 512 - Article 8 Alternation – indicates ‘(COMPANY) will not make, or cause to be made any alterations, improvements, additions and changes in or to the premises without the prior written consent of GPA and prior written consent of Navy.’ The IFB on P496 of 512 indicates ‘6. COMPLIANCE WITH SPECIFICATIONS AND OTHER SOLICITATION REQUIREMENTS: Bidders shall comply with all specifications and other requirements of the Solicitation.’ Does the above mean the bidder need to comply with NAVFAC specifications in order to acquire the prior written consent of Navy?

Article 8 Alternation

UXO

6a I would like to ask you to indicate Navy rule(s) that CONTRACTOR needs to follow, before the commencement of excavation, to acquire the prior written approval of Navy. It seems the procedure for CONTRCTOR to follow before the excavation have been varied as times pass-by. Your indication of most recent procedure approved by Navy could be appreciated.

Navy has provided the following process for Unexploded Ordinance guidance:

• Unexploded Ordnance (UXO) and other Munitions and Explosives of Concern (MEC) may be present at this site. Any subsurface excavation, digging, drilling or other disturbance of the surface requires prior written approval of Navy and shall be done in compliance with all applicable Federal, state, and local laws and regulations and with Department of Defense and Department of the Navy safety policies.

• Lessee shall comply with the following conditions, including, but not limited to:

- Provide minimum seven (7) days notification of intrusive activities;

- Reasonable consideration of alternate work schedules to minimize vehicular and


pedestrian traffic exposure;

- If MEC/UXO encountered on DON land, conduct “3Rs”: Recognize, Retreat and Report for all on-site personnel;

- Confer immediately with CJRM Regional Explosives Safety Officer to determine scope of investigation and requisite response action

6b

CONTRACTOR will not be able to foresee the location and the amount of the buried materials until the ground-surface is scanned. The buried materials may be found at the final layer scanned. If found, CONTRCTOR needs to continue the scan for further depth. It will affect the cost and the construction period. Will CONTRACTOR be able to negotiate with GPA to increase the bid price in case UXO issues heavily impact the cost and timely completion?

Following NAVFAC specifications

The IFB on P485 of 512 indicates as follows; PART 1 - QUAL SUPPORT REFERENCES ➢ B2-c. Provide the technical specifications and other information available for the generators included in the proposal NAVFAC specifications require high-level requirements; i.e. the design wind speed is higher than that of the regular case. PV panels need to be designed and manufactured on NAVFAC wind-speed. Will GPA reject the technical proposal if the proposed specification does not meet the NAFVAC requirements or accept it with lowering the score of evaluation scoresheet?


8 Page N.A.

Time extension

In order to select PV panels, invertors, ESS, etc. to meet NAVFAC requirements and to follow the Buy American Act, we need more time before the technical proposal. I would like to ask you to extend the cut-off date for receipt of technical proposal more than 1 month.

Please see revised bid schedule in Amendment #3.

5.16. Payment Milestones and Schedule

The IFB indicates as follows; Payment milestones have been selected to clearly identify the actual status of the portion of the Work completed rather than anticipated project progress schedules It seems the above payment procedure is applied to the construction work done. Could we understand the payment to be applied for Phase 3 is based on the product of power-output and the contracted power-purchase-price?

This contract shall be paid based on energy delivered and the bid energy price. No construction payments are to be made as GPA does not own this facility.

2.2.4. Use of GPA Facilities

GPA shows 6 sites in Table 2. South Finegayan site was once canceled by Government of Guam (see P 476 of 501). However, it was selected by NAVFAC (see P233 of 501 3rd para: After fully considering the comment, DoN determined that ---) Could we understand the reason which was raised by GOG to cancel has been rifted and South Finegayan site will be used for PV power development for the period of 20 to 30 years?

The document cited further explains in the paragraphs following as to reasoning and justification as it “supports existing energy security and mission needs of NBG and AAFB.”

2.4.3. Substation Short Circuit Capacity Values

I would like to ask you up to how many more MW Orote and Harmon substation can accept the power developed by the new PV power stations from sites of Phase 3.


Orote Substation and Harmon Substation

I would like to ask you to give us the latest as-built drawings and specification of Orote and Harmon substations in order for us to estimate the cost required for up-grading the above substations. The above as-built drawings and specifications include, but not limited to, architectural, structural, and control ones. I understand the above cost estimate will be done by GPA and GPA’s appointed consultant. However, we need the above items in order for us to prepare for the contingency amount.

1.37 “Excused Hours” Dispatch Down (as defined in

(line 1.37) The IFB indicates as follows;

Appendix K) 1.37 “Excused Hours” means the hours in the applicable Production Measurement Period in which (i) Seller or Buyer has declared Force Majeure, (ii) Seller has initiated a Dispatch Down (as defined in Appendix K), I understand Appendix K you are mentioning is on Page 141 of 501. However, Page 141 indicates Calculation of Weather Hours. I would like to ask you which page we will refer for the definition of Dispatch Down.

GPA defines dispatch down in page 134 of 501: “Buyer shall pay Seller, on the date payment would otherwise be due in respect of the day in which any curtailment is initiated by GPA for reasons other than Force Majeure or Seller Event of Default (“Dispatch Down”),

C2. Dispatchability (3)

C. POWER PRODUCT CHARACTERISTICS C2. Dispatchability (3) - Proposals not capable of energy shifting total daily solar generated energy shall be disqualified. I would like to ask your clarification of ‘total daily solar generated energy’. Would it mean the developer will charge all the energy generated during the daytime into the ESS and discharge them afterward? If so, I am afraid the energy generation of one day will be zero.

This requirement is to ensure that all projects shall have ESS capability to store and deliver the energy produced by Solar PV. It is not requiring production and delivery daily as this is dependent on the weather.

Letter from DPR of GOG to NAVFAC Archeological inventory survey and subsurface testing

The letter issued by Government of Guam (‘GOG’) to NAVFAC dated on June 5 2015 indicates GOG was not able to concur with NAVFAC determination based on the Draft Archaeological Inventory Survey and Subsurface Testing at Multiple Locations in Support of Navy Renewable Energy Projects on Guam report. Further, the letter issued by GOG to NAVFAC on July 24 2015, page 326 of 501, indicates many concerns and unacceptance of NAVFAC draft (see Page 330 of 501). NAVFAC, on the other hand, replied to GPA by issuing the letter dated on Aug 13, 2015, page 332 of 501, stating that ‘when we did not receive correspondence from your office within the extended review period, we were forced to act on our determination of No Historic Properties Affected, which we are confident is correct’. I would like to ask your clarification of the existence of historical properties in sites of Phase 3. Could I understand the possibility for the developer to encounter the historical properties during the period of construction is quite small? Or, is it mandatory for the developer and required by GPA and NAVFAC



to conduct the archeological inventory survey before the construction starts?

Time Extension for technical proposal submission

In order to understand the technical requirement of ESS such as ’energy shift of solar power to another time’ and ‘energy shifting total daily solar generated energy’, and further, in order to look for the vender who meets the above requirements, I would like to ask you to extend the cut-off date for receipt of technical proposal more than 1 month.


Obayashi Corporation inquiry dated 01/30/18: No Page Clause Question Response 1

Page 52 of 501

1. Overview The IFB on P52 of 512 indicates as follows; 5. The ESS must provide the following functions: o The primary purpose of the ESS shall be for energy shifting which is to deliver the solar produced energy at another time or period of the day.

Page 169 of 501

C2. Dispatchability (3)

The IFB on P169 of 512 indicates as follows; C. POWER PRODUCT CHARACTERISTICS C2. Dispatchability (3) - Proposals not capable of energy shifting total daily solar generated energy shall be disqualified.

[Question 1] Could I understand ‘total daily solar generated energy’ is equivalent to the quotient of annual minimum guaranteed output divided by 365? The generated energy becomes more in summer and less in winter. If the ESS has the capacity to save the maximum one-day generated output per year, the capacity is too much. I understand the capacity to save the average one-day generated output per year will be sufficient. However, I need the clear definition of ‘total daily solar generated energy’.

GPA requires for energy to be delivered at night due to its restriction in receiving additional renewable energy during the daytime. Thus, bidders must design for a PV and ESS system that will collect the energy for delivery after the energy production period or at evening/nighttime.


2-2

[Question 2]

Apart from Question 1 of the above, will you accept the following control concept as per your requirement of ‘energy shifting total daily solar generated energy’? Time zone 1: generation output not to be decreased while the aggregate demand is heavily increasing Time zone 2: generation output not be fluctuated while the aggregate demand is heavily fluctuated Time zone 3: generation output not to be increased while the aggregate demand is heavily decreasing Time zones are to be defined by GPA. The above concept comes from the requirement of Hokkaido Electric Power Company in Japan, asking the wind power developer to follow. The said requirement is noted below. (1) 7:00 to 10:00 generation output not to be decreased (2) 11:30 to 13:30 generation output not to be fluctuated (3) 16:00 to 19:00 generation output not to be decreased (4) 20:00 to 23:00 generation output not be increased The same figure enlarged is shown after this table.

GPA requires for energy to be delivered at night due to its restriction in receiving additional renewable energy during the daytime. Thus, bidders must design for a PV and ESS system that will collect the energy for delivery after the energy production period or at evening/nighttime.

2-3

[Question 3]

The ESS capacity shall be determined by taking into account of deterioration. The level and speed of deterioration depends on how the ESS is operated. Will GPA instruct the developer to save the total energy generated every day, or to save 80% of it, for example, and shift the same amount to night, or not to save at all sometimes? I like to understand the frequency and saving amount of the above instruction.

Bidders will have to make this consideration when determining their energy guarantees. GPA will still require delivery of energy within the contract year. The bidders have to determine degradation or incorporate upgrades/replacements within their contract term as part of their price bid.

KEPCO inquiry dated 02/02/18:

No. Category RFP page RFP article Question

1 Volume I 9 of 501

The Bidder's renewable resource project will have a maximum export capacity of 30MW(AC);

RFP stated that a maximum export capacity of 30 MW (AC) while 40MW of renewable capacity with Energy Storage System. Does it mean that one site (total 2 sites) can export 30MW?

This is the limit of ESS discharge capacity into the grid. Since the energy of the PV is stored the export can be larger than the PV system and delivered at a shorter time. This is dependent on the size of your inverter and interconnection design.

2 Volume I 10 of 501

The renewable resources shall conform to the Buy American Act for projects located on federal lands.

Please give us clear guidelines and instructions as to the applicability and scope of Buy American Act in this Guam Renewable Phase III Bid and any exemptions or waiver under FTA.

South Finegayan Site Update Please note that GPA is requiring a 50-foot setback (10 foot additional setback as requested by GWA) along the sewer pipeline route and bidders shall reflect this in their proposals.

In case of Finegayan, GWA will construct Sewer line. Can we install underground line or overhead line to connect PV components on sewer line?

The Sewer Line exists however GWA has notified GPA that a bypass line will be constructed above ground while the existing pipe is being sleeved. So no activity shall be allowed on the setback area as it is also a road access for GWA and its contractors vehicles and equipment. GPA will evaluate overhead request.

2.4.1.1 Site Interconnection Discussions

Q) At what AC capacity would we need to interconnect to the existing 34.5KV transmission system both in Naval Base Guam project and S.Finegayan? Q) According to Figure 2- Naval Base Guam Sites Interconnection, there are two substations (CDF site, Commissary site). As far as we know, the substation of the CDF is newly constructed. Is the substation of the Commissary site new or existing substation? Q) Could you kindly describe the transmission lines between Orote Substation and Apra Substation?

(Q1) GPA limits the interconnection capacity to 30MW at each of the project sites. This is the limit of the ESS capacity to discharge the energy it has stored from the PV. (Q2) There are no existing substations at either the CDF or Commissary lots in the Naval Base Guam site. GPA suggests interconnection to the existing 34.5KV overhead line that runs past these lots. Selected bidder will be required to build a substation for interconnection, via a loop system, into the grid via the existing transmission line. (Q3) Response forthcoming.

Opterra/Engie inquiry dated 02/07/18:

# Document Ref. Question / Clarification Requested Response 1 Invitation for Bid Since this project is on federal property, with roughly

half of the available land located on NBG, will the Department of Defense (DOD) require the facility design to be in accordance with the Unified Facilities Criteria (UFC) or any other specific Federal, Navy or DoD design codes and standards that are to be complied?


2 Pre-Bid Conference

Does GPA consider this IFB to cover 2 separate and distinct sites (S. Finegayan & NBG)? If so are bidders required to submit 2 separate bids and 2 separate bid bonds? Is it mandatory to supply a bid for both sites?

The S. Finegayan site and the Naval Base Guam sites are considered two different projects and bidders are allowed to bid on one if so desired. Technical and price proposals must be submitted separately for each project site. GPA will consider the bid bond requirement and respond in subsequent amendment.


There was a verbal statement made that all energy produced by the PV systems will be required to be stored in the ESS and shifted to peak demand hours. Will you please clarify GPA's system requirements.

GPA requires for energy to be delivered at night due to its restriction in receiving additional renewable energy during the daytime. Thus, bidders must design for a PV and ESS system that will collect the energy for delivery after the energy production period or at evening/nighttime. However, GPA may dispatch the plant’s energy during the day if and only when the system is capable to receive energy without causing system stability issues (i.e. other renewable plants are offline, isolated system, increased load demands, etc.)


If all energy produced will be stored until peak demand, will there be any protocols required or desired to allow GPA to dispatch the energy during PV production hours? How will this component be evaluated in the Technical Proposal review?

GPA requires the PV and ESS system to design for peak or nighttime delivery. The PV and ESS system shall be capable of delivery during production hours. Bidders shall provide description of energy dispatching capabilities and restrictions.


DON stated the purpose of the Master Lease with GPA is "Microgrid capable renewable energy generation, storage and distribution to the GPA grid." What are the microgrid capable requirements of the system?

The PV and ESS features from this bid well as the point of interconnection for these projects helps to satisfy the purpose of the lease.

Conference

Does any microgrid requirement need to follow NAVFAC's Microgrid Design Guide (P-601) and/or P-602?



What risk management framework and / or cybersecurity requirements are to be followed for compliance?



DON stated due to MEC/UXO, any subsurface disturbance shall be done in compliance with all applicable laws, regulations, as well as DOD & DON safety policies. The safety policies relating to MEC for military projects on federal property on Guam are substantial and add significant time and cost to a project. Will the specifications and requirements for these polices be provided in order to ensure proper resources are allocated to this effort?



In following all applicable laws, regulations, as well as DOD & DON safety policies, will the successful bidder be required to follow the requirements of the EM 385-1-1 (US Army Corps of Engineers Safety and Health Requirements Manual) which has been adapted by the Navy?


10 Pre-Bid Site Visits

The S. Finegayan site was a former military housing area. While a single active sewer line is identified on the plans with a right-of-way description, there is no description of any of the utilities abandoned in place in the neighborhoods (e.g. sanitary sewer, water, storm drain, electrical, telecon/fiber optics, etc). Will you please provide detailed plans indicating the locations of these utilities, as their size, number, and locations may significantly affect the design requirements for the PV mounting system if these cannot be disturbed (or must be returned to their current existing condition at the end of the lease).



On NBG at the existing PV site location (one of four sub-sites on NBG designated for this bid), there were at least 3 large concrete slabs verbally described as areas where cleaning chemicals may have been stored and minimal soil disturbance may be allowed. Will you please include details of these locations on a set of plans (exact delineation of area of concern) and list any restrictions on use there.

Response forthcoming. Please refer to Item 2 of this amendment which includes excerpts from the Master Lease.


On NBG at the existing PV site location (one of four sub-sites on NBG designated for this bid), a statement was made that road access to the existing, fenced PV site would need to provided. The existing site would otherwise be potentially isolated/surrounded by the new installation of PV. Will you please provide the exact requirements for this access road such as dimensions and whether it is allowed to tie into Marine Corps Drive or must tie in from Shoreline Dr.
