Case Studies

Heritage Green Retirement Home

Overview

Location: Hamilton, ON
System Size: 100 kW solar / 180 kWh energy storage
Project Type: Flat roof construction with battery storage to offset grid consumption.
Project Scope: Electrical Engineer-of-Record

Challenge

Client wished to have a grid connected rooftop solar project but was advised by the utility that there was no available grid capacity in the area and that grid upgrades would take several years.

Endura’s Approach

Endura Energy designed the largest non-military hybrid off-grid solar PV and energy storage system in Ontario to power the heating and cooling rooftop units in the building. In times during low solar generation, the loads are automatically transferred back to the grid until solar energy yields come back up.

Value to the Client

The retirement home was able to meet its objective of going solar despite the fact that they could not connect to the grid. The hybrid solar PV and battery backup system is able to provide significant peak shaving of the building’s electrical energy costs. Additionally, the system was designed to be converted into grid connection mode once grid capacity is made available by the utility.

Sandringham and Woodville Solar Farms (Invenergy)

Overview

Location: Kawartha Lakes, Ontario
System Size: 25 MW DC (2 sites)
Project Type: Utility scale ground mount
Project Scope: Electrical Engineer-of-Record

Challenge

The permitting authorities set aside areas for environmental protection.

Endura’s Approach

Endura Energy addressed the developer’s desire to protect the environment and maximize project energy yield by optimizing the design around the protected areas.

Value to the Client

The solution allowed the developer to meet project size targets while protecting important habitat lands and without impacting constructability or system costs.

Sunny Shores Solar Farm (Oakville Hydro)

Overview

Location: Picton, ON
System Size: 14.0 MW
Project Type: Utility scale ground mount
Project Scope: Full Engineer-of-Record

Challenge

The developer had procured a very large project site and wanted to maximize the energy yield of the plant, however a low lying region in the middle of the site limited options due to frequently flooding during spring runoff.

Endura’s Approach

Endura Energy developed a design utilizing a 1000 V DC system that allowed a 140% DC:AC oversize ratio and utilized only six inverters.  The entire site was maximized through a redirection of run off flows around the solar array and through a culvert under the site.

Value to the Client

The developer was able to fully utilize the vast project site and maximize their project investment.
