About Saddlebrook Solar + Storage

test

TC Energy is currently constructing and will operate a solar project in conjunction with an energy storage facility. The Project has two phases of construction. The first phase of construction includes a
solar-generating facility and the second phase includes the construction of an energy storage system.
The Project is located on TC Energy-owned land at the Saddlebrook industrial Park, southeast of the intersection at Highway 2A and Township Road 200, in 31-19-28-W4M in Aldersyde, Alberta.

PROJECT DETAILS

The Project is being developed in two phases:

PHASE ONE

Phase One of the Project consists of the installation of 81 megawatts (MWac) of solar generation, which can generate enough electricity to power approximately 20,000 homes. The project will be operational at the end of 2023.

PHASE TWO

Phase Two of the Project consists of the installation of a utility scale storage facility, up to 6.5 MW, 40-megawatt-hours (MWh). Both phases will utilize inverter technology to convert the electricity produced by the solar panels and battery into alternating current. The electricity produced will feed into the Alberta Interconnected Electric System (AIES) through an existing substation located on the Project lands.

PROJECT TECHNOLOGY

The Project uses bifacial solar panels that will generate electrical energy from both sides of the panel. The front side of the panel generates electricity from direct sunlight and the rear of the panel generates electricity from indirect sunlight, such as light reflected off snow-covered surfaces. The Project will be the first in Canada to utilize Lockheed Martin’s GridStar® Flow energy storage system, a long-duration flow battery technology.

The energy storage system will be used to provide power to Alberta’s electricity system in times of peak demand and provide other grid-stabilizing services.

The Project’s environmentally friendly technology is expected to reduce greenhouse gas (GHG) emissions and air pollutants by providing emissions-free energy to the grid and displacing fossil-fuel generation. The electricity generated by the solar panels is expected to directly reduce GHG emissions by approximately 73,600 tonnes of Carbon Dioxide Equivalent (CO2e) per year, which is the equivalent of taking approximately 16,000 cars off Alberta roads.

In addition to the solar panels and energy storage system, the Project will include the following:

  • Substation with transformer and electrical control equipment
  • Electrical inverter stations to convert the generated Direct Current (DC) power to Alternating Current (AC) power
  • Buried (where possible) electrical collector lines to transmit AC power from the inverter stations to the substation
  • Fencing around the perimeter of the project to regulate access to the site
  • Internal site access roads
