7. Questions

DNR.MEO – Straits PV and EV Page 1 of 7

Straits State Park:

720 Church Street, St. Ignace, MI 49781

The Michigan DNR intends to own and operate behind-the-meter solar PV systems at Straits State Park. This scope of work includes the design and build of PV arrays to offset electricity for two utility meters and for the installation of publicly accessible EV chargers. Available site data including drawings, photos, and load profiles are provided as additional exhibits.

An overall design concept is shown in Figure 1. Cloverland Electric Cooperative, the regional electric utility provider, has communicated one area of PV arrays may offset two utility meters. This is conditional upon each utility meter connecting to independent AC power generators (inverters). Additionally, DNR plans for a Level 2 charger with two ports to be installed within the North Campground electrical circuit.

Figure 1: Overall PV and EV design.

OsgaR Text Box Attachment 1 revised 02-03-2025

DNR.MEO – Straits PV and EV Page 2 of 7

Overall PV Design

The PV design details are applicable for both utility meters except when specifically defined per meter.

Figure 2: PV Array area.

Project details and assumptions:

1. Array Layout: 30 degree fixed-tilt, 2-high modules in portrait, min 3’ from ground.

2. Major Equipment:

a. Modules: Bifacial modules are Tier 1 or equivalent.

i. Total Project Size Estimate: 149.5 kW-dc.

ii. HQ Meter Size: 17.5 kW-dc

iii. N Campground Meter Size: 132 kW-dc

b. Inverters: May be microinverters or string inverters. Multiple inverters are preferred per meter.

i. HQ Meter Voltage: Single phase, 120/240V.

ii. HQ Meter Inverter Size Estimate: Variable pending microinverters or strings. Assume inverter loading ratio in the range of 1.2 – 1.3.

iii. N Campground Meter Voltage: Three phase, 13.2 kV

DNR.MEO – Straits PV and EV Page 3 of 7

iv. N Campground Inverter Size Estimate: DC:AC ratio of 1.2 – 1.3. Variable pending bidder proposal and explanation of 1,000V or 1,500V string inverters.

c. MV Equipment:

i. N Campground Meter: The 13.2 kV interconnect will require a step-up transformer and need to integrate with the existing DNR owned MV cable between the utility meter and the N Campground electrical infrastructure. The Bidder should explain their proposal of new DNR-owned medium voltage equipment.

d. Balance of System:

i. HQ Meter: The Bidder should provide a brief explanation describing the feasibility of modules sharing a rack for two different meters and inverters, and any potential grounding implications with the systems sharing electrically conductive equipment.

ii. N Campground Meter: The two key areas for PV electrical design are near the PV array and near the interconnect. The Bidder may propose a direct bore solution in conduit for the PV power as DC or as medium voltage AC, low voltage AC is assumed impractical.

Note, the area near the utility’s meter is land constrained.

3. Land Constraints:

a. For the PV Array: Road to West, trees to North and South, property boundary and ditch to East.

Setbacks from the road, north tree line and southern trees should be communicated in Bidders explanation.

b. The area near the N Campground Meter is also relatively constrained due to the wooded surroundings.

4. Shade Details: Tree trimming and vegetation removal is expected to be performed by DNR, Bidder should provide an explanation of their preliminary assessment of tree trimming in proposal.

5. Fence Requirements: DNR prefers no permanent fence around the PV array but will defer final requirements to comply with applicable codes. For example, it is assumed the National Electrical Code requires fencing around systems greater than 1,000V. If fencing is not proposed nor required, Bidder should include a solution for minimizing the quantity of exposed wire as risk mitigation from the general public.

6. Underground Conditions:

a. Utilities: Known underground utilities include DNR owned sewer and water lines in the PV array area. There is a survey drawing showing the utilities, though the dimensions of the drawing appear inaccurate. For example, the entrance road has been measured to 16’ while the survey drawing states 20’. Bidders should include an explanation of how to manage construction when existing underground conduits are assumed to not include traceability.

b. DNR requires all underground wires be installed in conduit.

7. Data Acquisition System: In the bid provide the bidder’s recommendation for long-term data monitoring inclusive of any necessary long-term costs such as cellular plans or a method to connect to site communications.

8. Load Data: Annual electricity usage including EV charging projections are as an attachment to the RFP.

9. Interconnection: Areas of interest are provided in diagrams here and additional photos in the exhibits.

a. HQ Meter: Recommended line side POCC prior to HQ panelboard, such as adjacent to utility meter, or the most feasible location between the utility ownership and DNR ownership.

DNR.MEO – Straits PV and EV Page 4 of 7

b. N Campground Meter: Recommended line side POCC near meter.

10. Utility and Rate Case: Cloverland Electric Co-Op. General Service, GEN1. Full Net Metering rate.

11. Utility sizing constraints: 110% annual electricity offset. Size is under 150 kW-ac full net metering cap.

12. Financial Incentive Potential Qualifications: IRA: Under 1 MW (30%), Bidder to provide estimate for domestic content percentage expectations.

Overall EV Design

The charger(s) will be installed near the entrance to Straits State Park to ensure convenient access for visitors

(see Figure 4). The installation will include mounting the charger on a pedestal, with provisions for cable management to keep the charging cables organized and easily reachable.

1. Public Chargers:

a. Number of Chargers 1

b. Number of Ports per Charger: 2

c. Connector(s): J1772 and NACS

d. Charger Type: 80 A Dual port, pedestal mount, 15ft cable or longer

e. Rated Capacity (DC power): Not to exceed 80A (19.2 kW)

f. AC Grid Voltage; Input Voltage: 120 / 240 V ; 120 / 240 V

g. Communications: Cellular connection

h. Payment Options: Must support EMV contactless credit/debit reader

i. Charger Order/Model code: Bidder to provide specific charger model with all features

j. ADA Compliance Requirements: See EV Parking Design example.

k. Must follow site design requirements as described by ChargePoint for installation.

2. Site preparation may include trenching, mounted concrete pads, and restriping parking stalls. The charger(s) will be configured for network communication to support remote monitoring and payment options. Placement will prioritize ADA accessibility and ease of use for the public (see Figure 5, EV

Parking Design example). Bidder will be responsible for providing final parking design. The installation will follow the charger’s specific guidelines for proper setup and compliance with all requirements.

Compliance and Standards

All installations will adhere to regulatory standards, including National Electrical Code (NEC) requirements, ADA compliance for accessible parking spaces, and DNR Guidelines.

Installation Process and Timelines

The project will proceed in several phases:

1. Site Assessment and Design: Evaluating site conditions, electrical capacity, and finalizing charger placements.

2. Permitting and Procurement: Securing necessary permits, including LARA permitting, and procuring equipment.

3. Installation: Charger installation, electrical upgrades, testing and parking striping.

4. Commissioning: Final inspections, operational tests, and training for DNR staff.

The anticipated project timeline from the start of the site assessment to final commissioning should be proposed to DNR.

Operational Requirements

Chargers will be connected to a network for monitoring and payment processing. Public chargers will support contactless payment via credit/debit cards. DNR will manage long-term operations but may consider a routine maintenance proposal from the winning Contractor.

Acceptance Criteria

• All chargers are installed and operational according to the specifications.

• Final inspections are passed, and necessary permits are closed.

• DNR staff receive training on charger operation and maintenance procedures.

• Any punch list items identified during commissioning are resolved.
