3 OVERVIEW: PRODUCTION & INCOME Location Design Summary: Name: Stanhope Airport Location: N, W Min. Temp.: C Max Temp.: C Weather Properties: Station Name: Meteonorm Data Source: NASA Location: N, W 100kW Photovoltaic Ground Array Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Estimated Annual Production (kwh): 124,335 Estimated Annual Gain in Production (kwh) Tigo (15%): 18, ,985 Feed-In-Tariff (v2.1) Rate: $0.388 Estimated Annual Income: $55,475

4 SITE ASSESSMENT It is the opinion of Haliburton Solar and Wind (HSW) that two potential installation locations exist to support a single 100kW (DC) ground-mount photovoltaic array. These include: Location No. 1: Within existing gravel pit. Location No. 2: East of the gravel pit. The process of identifying these locations involved considering factors such as: Amount of solar access at location. Existing grid service. Ease of access to location. Scope of site preparation activities. Usable area of location. Both locations share a single point of access to Barry Line Road, are expected to experience similar levels of solar access, and feature a usable area of approximately one (1) acre. Pending confirmation from Hydro One, grid service currently terminates where Barry Line Road meets the existing service road. Location No. 1: Notable site preparation activities: Excavation services associated with leveling the usable area Extending existing grid service to the installation area

5 Location No. 2: Notable site preparation activities: Excavation services associated with leveling the usable area Extending existing grid service to the installation area Construction of an additional service road Tree removal It is our opinion that the additional distance to extend grid service to Location No. 1 as well as the larger scope of excavation services required at that location, will be material enough to exceed the cost of the additional site preparation activities required at Location No. 2. In summary, it is the opinion of HSW that Location No. 2 represents the most ideal installation location due to lower estimated site preparation costs.

6 GROUND DESIGN Recommended Equipment Module Manufacturer: Heliene Model: HSC P Inverter Manufacturer: Fronius Canada Model: IG Plus V 10.0kW Optimizer Manufacturer: Tigo Energy Models: MM-ES, MMU, and GTWY Refer to Appendix for overview of Warranty information. Solar Access Annual: 97% Summer: 98% Winter: 95% Array Properties Length (ft): 170 Width (ft): 135 Azimuth: 180 Tilt: 35 Derate: 0.84 Module Layout Rows: 10 Modules (/Row): 40 Usable Area of Location Length (ft): 328 Width (ft): 164 Considerations & Rationale Any effectively designed photovoltaic system under the Feed-in-Tariff (FIT) program seeks to optimize performance while controlling cost, for the purpose of maximizing overall return on investment. With this in mind: Proposed module layout allows array to be oriented true south. Use of Tigo optimizers results in several unique benefits, such as : - Producing up to 25% more power density. - Reduce operating and maintenance costs by up to 10% - Software platform allows module-level, system-level, and fleet-level assessment. - Arc, fire and safety risks are monitored with automatic module-level shut-offs. Fronius IG Plus V product line achieves one of the highest efficiency values for transformer inverters, with a maximum efficiency of 96.2%. In addition, Fronius production method allows for ease of component replacement, if required, on site which results in minimal downtime of system.

7 FINANCIAL ANALYSIS Overview of Return Payback Period (Years): 8.11 Net Present Value (NPV): $335,587 Return on Investment (ROI) w/o TVM: 147% Internal Rate of Return (IRR): 10.72% Return on Investment (ROI) w/ TVM: 75% Notes 1. Provincial Bond Yield Rate: 3.54% 2. Term of Contract/Bond (years): 20 Considerations & Rationale 1. Provincial Bond Yield Rate. Used as the discount rate to estimate the present value of future cash flows. As provincial bonds and the Feed-in-Tariff (FIT) program are offered by the Government of Ontario, it is the opinion of Haliburton Solar and Wind (HSW) that the bond yield rate for a term of similar duration to that of the FIT contract term, provides a reasonable basis for comparison. Province of Ontario bond with 2033 maturity. Ask Yield rate used as it offers a stronger representation of yield to maturity than coupon. Obtained from TDWaterhouse.ca on 22-Feb FIT Rate. Based on the price schedule for FIT v2.1. As the small FIT window has closed, this rate is assumed to be constant. 3. Value of Initial Investment. Estimated cost to install is based on a range of $4 to $5 per watt. Estimated site preparation costs have not been included in the determination of this range. In the event of a tendering process, it is our opinion that it may be in the

8 municipality s best interest to separate those costs directly associated with site preparation from those costs directly associated with the installation of the photovoltaic system. Haliburton Solar and Wind (HSW) estimates the site preparation costs associated with Location No. 2 at $70, Operation & Maintenance (O&M). Effectively designed photovoltaic systems should incur minimal O&M costs. Interaction by personnel is typically reflected in a monitoring capacity. Monitoring should be conducted primarily through the use of appropriate software followed by occasional visits to the location. For example, environmental factors will require visits to the location. During the winter season, this could mean keeping the modules clear of snow and ice. During the fall season, this could mean clearing modules of fallen leaves. Methods of Performance Measurement Payback Period: Return on Investment (ROI): Net Present Value (NPV): Internal Rate of Return (IRR): Results Refers to the period of time required to recover the sum of the original investment. Does not consider the impact of time on the value of money (TVM). A method used to measure the rate of return on invested capital by relating profits to invested capital. May be calculated to consider TVM or not. When the ROI of various projects are compared, projects are prioritized by those which offer the highest to the lowest. Uses TVM to evaluate the return on long-term projects by summing the present values of all incoming and outgoing cash flows, taking inflation into account. The discount rate used was the rate of return for a comparable investment. Indicates how much value an investment adds to the owner. If the NPV is positive, the investment is considered acceptable. Measures and compares the profitability of investments without considering the impact of environmental factors (Ex. Interest rate or inflation). It acts as an indicator of investment yield and is compared against an established minimum acceptable rate of return (benchmark). If the IRR is greater than the benchmark, the investment is considered acceptable. The payback period for this project is 8.11 years on a 20 year contract. Whether TVM is considered or not, the ROI for this project appears strong. When this project is compared to a similar investment opportunity, this project provides $335,587 in additional value. This approximate yield of this project (10.72%) is greater than the approximate yield of a comparable investment (3.54%).
