Westbridge wins OK for solar + energy storage project

Regulators in Alberta approved a utility-scale solar + energy storage project and associated substation, all developed by Toronto-based Westbridge Renewable Energy. 

The Georgetown project is the first of Westbridge’s four Alberta projects to receive power plant and BESS approval from regulators. 

The project is expected to include a solar power plant with a capacity of up to 230 MWac / 278MWdc, BESS with capacity of up to 200 MWh, and the associated Mossleigh 1051S Substation. 

The solar power plant would include some 433,000 solar modules on a fixed-tilt racking system, 75 inverter and transformer stations, and underground collector lines that would connect to the substation.

The Georgetown BESS would consist of 80 energy storage containers for lithium-ion phosphate batteries, 20 power conversion stations each having two inverters and a transformer, and two auxiliary transformers. It would be rated up to 100 MW and have a storage capacity of 200 MWh. 

The substation would contain one 240/34.5kV, 256mV ampere transformer, one 240kV circuit breaker, eight 34.5kV circuit breakers, up to two 10mV ampere capacitor banks, and associated substation equipment. 

In related news, Westbridge said it added the Eastervale Project in east-central Alberta to its portfolio. Eastervale has a target capacity of 300 MWp solar photovoltaic with 200MW/400MWh of BESS with a two-hour battery duration. The project is making its way through the Alberta Electric System Operator interconnection process.

Once final equipment selection for the Georgetown project is made, the developer is expected to confirm whether the design will increase the land, noise and environmental impacts beyond those reported in its initial application to regulators.

A solar glare assessment indicated that the project’s solar panels will mounted on a fixed-tilt racking system with a tilt angle of 28 degrees, and assumed that the project would use anti-reflective coating on the solar panels. The assessment considered five potential receptors near the project: two dwellings and three roads.

The assessment found that glare would be a factor for no more than 20 minutes to 72 minutes a day at any of the sites. The regulatory decision directed that anti-reflective coating be applied to the solar panels.

The project could enter service during the third quarter of 2023.
