EXECUTIVE SUMMARY

Colby Company has prepared this Extra Field Investigation Report for the U.S. General Services

Administration (GSA). The objective of this study is to determine the feasibility to upgrade the facilities to a three phase, 480V electrical service in support of the future Land Port of Entry (LPOE) that is 100% carbon neutral, and meets the latest edition of the CBP LPOE Design Standards. This report will document the existing conditions as well as the revisions and costs necessary to upgrade it to a three phase, 480V service. It will define the utility cost for poles and other utility equipment, excavation, tree clearing and other associated implementation costs involved. This report includes an aerial view of the proposed three phase power service pathway as well as possible renewable energy opportunities.

Coburn Gore LPOE, Coburn Gore, ME Existing Power

Location The Coburn Gore LPOE is located in Coburn Gore, ME, a small unorganized township in Franklin County.

Coburn Gore is an isolated setting about 20 miles northwest of the small town of Eustis, Maine. Coburn

Gore is across the border from Woburn, Quebec. See Figure 1 for a map showing the location of the

Coburn Gore LPOE.

Summary of Existing Conditions The Coburn Gore, Maine LPOE is adjacent to neighboring Woburn, Quebec LPOE, operated by the

Canada Border Service. The Coburn Gore LPOE consists of a main building with an attached four-bay garage and car canopy. There are also four residential buildings that house government staff on the north side of State Route 27. The property is relatively flat and mostly wooded aside from lawn areas near the buildings. Beyond the LPOE, there are many acres of undeveloped woods. Some of this land is protected by conservation groups, the Indian Nation, and as a National Scenic Highway. See Figure 2 for a view of the existing structures on the property.

The 2018 Parsons Feasibility Study recommended a future LPOE buildout that would require land acquisition northeast and east of the existing property. The proposed LPOE would include a reconfigured site layout with a new main building, garage, traffic lanes, parking, and supporting facilities. Additionally, the four existing GSA residences would be relocated, the existing historical main building would be renovated, and a new living quarters building would provide housing for ten officers.

Figure 2: Coburn Gore Site Structures

Electrical

The existing single phase electrical service to the Coburn Gore LPOE is provided by HydroQuebec (HQ).

HQ owns the power lines in Canada and has a high voltage of 12,470 Volts - 13,800 Volts at the border.

HQ and Central Maine Power (CMP) have an agreement to step power down at the border to 240 Volts, typical for residential use for use at the LPOE. HQ supplies power to the border and CMP distributes power using CMP owned poles on the US side including the LPOE. Each company has a transformer on

either side of the border. The current Service Entrance Main Distribution Panel is a 120/240V 1ph, 3W, 400 Amp Panel. The facility also has a 50KW generator which provides emergency power via an

Automatic Transfer Switch (ATS).

The electrical power requirements per 2018 CBP LPOE Design Standards, Section 19.2 state the following: “Essential power to the facility shall be provided via commercial utility power with an engine-generator (E/G) backup, and automatic transfer switch (ATS) feeding the essential main distribution panel (MDP). In the event of a commercial utility power outage, the E/G start-up is automatically initiated and the ATS shall switch from the commercial utility power to the E/G power. If domestic utility power is not feasible, power shall be drawn from the foreign country’s utility company power grid or substation. All electrical devices and equipment shall be provided at 60 Hz, 480V line-line.

The designed electrical system shall have sufficient capacity to supply power for the full design load, as well as 50 percent expansion of the full design load.”

The future proposed LPOE will include a new Main Building and 10 new Officer Living Quarters while keeping the Existing Main Building and Housing as well as additional parking and processing areas. Based on square footage, intended use and a 50% expansion of full design load, the new Service Entrance Main

Distribution Panel will need to be a 480V, 3PH, 400 Amp Panel. It also needs a new 300KW Emergency

Generator.

Proposed Three-Phase Power Strategy There are two alternatives to providing three phase power to the Coburn Gore LPOE: From CMP in the

United States and from HydroQuebec in Canada.

Power from CMP in the United States

Three phase power in the United States ends at 31 Campbell Road in Eustis, 22.1 miles away. Single phase power ends about 14 miles away. See Figure A of Appendix A for an aerial view of the proposed pathway. The Coburn Gore site currently gets single phase power from HydroQuebec. Providing three phase power to the site from CMP would require over 600 poles of which about 70% would require tree trimming. There is known ledge in the area, which would increase the cost of construction. Some of this land is protected by conservation groups, the Indian Nation, and as a National Scenic Highway so it would require acquiring easements and permitting.

Power from HydroQuebec in Canada

Three phase power in Canada is 2.2 miles away from the Coburn Gore LPOE. See Figure B of Appendix A for an aerial view of the proposed pathway. Single phase power is already provided to the LPOE from

HydroQuebec. This option would require approximately 61 new poles since poles need to be taller for higher voltages. Ledge is known to be in the area, so it is anticipated that some of the poles being

285.082.001 – EFI Report December 2022

COBURN GORE LAND PORT OF ENTRY (LPOE), MAINE

STUDY FOR THREE-PHASE POWER

replaced would be installed in ledge. Existing wire does not need to be demolished. Where there is single phase power already, 2 phases of wire will need to be added. Other utilities such as telephone and cable can be reused. All power and utility wires can remain live during relocation so there should be no service interruption. There would be up to 8 hours of no power but other utilities should have no service interruption. Hydro Quebec would pay for a transformer and meter on the Canadian Side of the Border.

Coordination with CMP would be required to distribute power from the border to the building (requiring

2 new poles and phase wiring) similar to what is done for single phase power. CMP would buy power from HydroQuebec and the LPOE would buy power from CMP.

No tree clearing is anticipated for the upgrade of the 61 existing poles, as the overhead route already exists for single phase power, and tree clearance is already maintained for the existing power lines. No new easements are anticipated as there are no new power routes required for this project. No land development permits are anticipated because all work would be conducted in the right-of-way to upgrade the existing poles. Coordination is necessary with HydroQuebec, the Utility provider.

Renewable Energy Solutions Renewable Energy Solutions considered at this LPOE Site were Wind and Solar. Geothermal is being considered as a separate project.

Solar

Photovoltaic (PV) Solar Systems- Rooftop and Ground Mounted PV Panels turns light energy directly into electricity. This power can be used directly by the facility as it is created, exported to the Grid to earn credits, or stored in batteries to be used later.

Things to consider for rooftop solar panels are the orientation of the building, how much usable rooftop space is available and what obstacles are on the roof. Ground mounted systems have the advantage that a perfect angle can be obtained for maximum production. In addition, a 1 or 2 axis tracking system can be included so it moves with the sun during the day and over the course of a year. This could mean the need for less panels. A disadvantage would be that land would be needed.

Other Solar options considered but were found to be unfeasible were Solar Water Heating and

Concentrated Solar Panels (CSP). Solar water heating only heats water and does not produce electricity.

The LPOE facilities do not have enough of a demand for hot water that justify this type of system. It also would be competing for roof space with PV Panels that do produce electricity. CSP is more appropriate to large scale industries (utility grade power production) taking up extensive space at a very expensive cost.

For this site, either a rooftop PV system shown in Figure 4 or a ground mounted PV system shown in

Figure 5 would be feasible.

COBURN GORE LAND PORT OF ENTRY (LPOE), MAINE

STUDY FOR THREE-PHASE POWER

If a rooftop option was selected, the new Main Building and new Officer Housing building would be the best locations for the new system since the installation of rooftop mounted systems on a historic building would need approval by Maine SHPO. The usable rooftop area facing southward across both buildings could accommodate up to a 75KW System which requires approximately 4000 sq ft. Estimating a 40KW system on the Officers housing and a 35KW system on the new main building with their respective orientation to the South at this geographic location, it could produce in total 91,300 KWh/year at an installation cost of approximately $225,000-263,000. If a smaller system is desired to save costs, a

50KW system could still produce 61,700KWh/yr at a reduced cost of $150,000-$175,000.

Ground Mounted Systems would be an option at this site if needed or preferred. There are 27 acres being proposed to be acquired for the future LPOE and based on the proposed plan there is some unused land available. There are also many acres of undeveloped woods surrounding the site that could be potentially acquired in addition to the 27 acres though much of this land is protected by conservation groups, the Indian Nation and as a National Scenic Highway. The ground mounted systems use the same panels and are priced the same as rooftop installations. They also and use roughly the same amount of square feet of space depending how much separation you want and how you want to orient them. A single Ground mounted system may be a better option at this site versus having the panels on two buildings in two different locations. It would also allow for a larger system with the perfect orientation and tilt toward the sun. For example, a 100KW fixed open rack system with a 45 degree tilt, facing in a directly south orientation would produce 129,000 KWh/year at this location with an installation cost of approximately $300,000-350,000. These ranges in cost are due to it being determined two ways. The low end was calculated using the industry standard $3/Watt rule of thumb. After contacting local vendors, this rate is closer to $3.50/W for a full installation including labor which is how the high end was calculated. The total production of KWh/year was calculated using the PV Watts calculator on the

National Renewable Energy Laboratory (NREL) website. See Appendix C for the calculation and result of a Ground Mounted 100KW System. A 100KW system would require about 5500 sq ft of space.

Permitting would only be required by the Maine Department of Environmental Protection (DEP) if more than an acre (43,560 sq ft) of land was disturbed. If 1-axis tracking is added, it adds approximately $2/W.

This is less common due to the added cost. The trackers also increase the amount of space needed but could mean less panels that are needed.

Wind

Wind turbines turn kinetic energy of the wind into electricity through rotating blades driving a generator.

Wind power is most efficient at the utility scale since the huge towers can reach the energy-rich wind speeds at higher elevations. At the opposite extreme, small rooftop wind turbines are not efficient since they tend to only receive weak or turbulent winds, would not provide the desired KWh needed, and it would require significant structural support.

The best option would be a pole mounted wind turbine. A 50KW wind turbine, for example, would be on a pole at least 100ft high with blades 30-60 ft in diameter. See Figure 6 for an example of this type of

285.082.001 – EFI Report December 2022

COBURN GORE LAND PORT OF ENTRY (LPOE), MAINE

STUDY FOR THREE-PHASE POWER

Wind turbine. It is large but does not take up much land; this site could accommodate it and the energy needs warrant it. A 50KW wind turbine would produce approximately 100,000-110,000 KWh/year. Power can be transmitted to the grid or stored in batteries.

KWh/year produced can be estimated by Efficiency x Max KW x 8760 hours/year . Efficiency depends upon the size, type, manufacturer and blade length. Longer blades produce more KWh. Wind Turbines in the 10KW-50KW range have efficiencies of approximately 0.25 to 0.35. The wind conditions also have a significant impact. According to Energy.gov, the average annual wind speed for the Coburn Gore area is

5.0 to 5.5 meters per second at 30 meters high, see Appendix D for the State of Maine wind resource map. Areas with good exposure to prevailing winds and annual average wind speeds around 4 meters per second and greater at a 30 meter height are generally considered to have a suitable wind resource for small wind projects. Since the winds in this region are at the low end of viability, the lower end of efficiency was used in calculations.

The cost of a pole mounted wind turbine varies from approximately $4 to $8 per Watt depending upon the size and type of Wind Turbine selected. For a 50KW Turbine, the cost would be approximately $6 to

$7 per Watt making the cost of materials and installation in the range of $300,000-350,000.

Renewable Energy Solutions Comparison Summary

For this site, either a 75KW or 100KW solar system or a pole mounted 50KW Wind Turbine is recommended. See Table 1 for a comparison of feasible Renewable Energy Solution’s installation costs and energy produced per year.

Table 1: Comparison of Renewable Energy Solutions

Although the costs and energy produced appears to be similar, in comparison to solar panels, wind turbines can be less predictable and are more costly to connect to the grid due to the infrastructure required and have more maintenance due to all the moving parts.

STUDY FOR THREE-PHASE POWER

Solar and wind can be used together to compliment each other. Though wind is intermittent, it does blow at night and stronger in the winter, when solar levels are low. Both Wind and Solar renewable energies can be used to power heat pumps which can be used in conjunction with the geothermal wells currently being studied as another project.

Cost Estimate Summary Due to the low feasibility of getting power from the United States, CMP was reluctant to provide an estimate. CMP’s cost estimate is based on the length of the proposed pathway and average costs per foot. The average cost without ledge work is $50/ft. For 22.1 miles, this is 116,688 ft x $50/ft =

$5,834,400 without the additional costs of working in ledge and permitting. CMP expected the total cost of the project to be in the range of $6 to 8 million.

A request for a cost estimate from HydroQuebec was made in September for work to be done at 1020 ch des Lignes, Saint-Augustin-de-Woburn, QC G0Y 1R0 and a confirmation number of 23159178 was received on October 4, 2022. The HydroQuebec point of contact is Simon-Pierre Turcotte at turcotte.simon-pierre@hydroquedbec.com. An email was received on October 11, 2022 indicating that the technician Jose Alexander Herrera has been assigned and it takes 18-20 days to complete the estimate. A cost estimate from HydroQuebec was received on December 15th, 2022. The estimated cost from HydroQuebec was $268,340CAD ($193,756USD). See Appendix E for the letter from HydroQuebec.

The Cost Estimate provided in Appendix B assumes the three phase power will come from HydroQuebec in Canada, and ledge would be encountered for some of the pole replacements. The Cost Estimating

Workbook (CEW) is an estimate developed using an engineering estimating tool RSMeans similar to what would be used if it were being installed in the United States and is summarized as follows:

See Appendix B for the details of the Cost Estimate. This cost is to upgrade to 3 Phase Power. It does not include upgrading to a Renewable Energy Resource.

Obtaining Three Phase Power Comparison Summary

Obtaining Three Phase Power from the United States isn’t feasible. The Coburn Gore LPOE already gets power from Canada for this reason. Its recommended to pursue 3-phase Power from HydroQuebec in

Canada as well. See Table 2 for the Comparison of costs of the two alternatives.
