On Sunday, Feb. 23 from 1 to 6 p.m. at WCSS (3088 Dunrobin Rd.) representatives from Evolugen will answer questions and provide information on their project during a South March BESS Open House.

In the meantime, below are answers to frequently asked questions on the project provided by Evolugen.

What is a Battery Energy Storage System (BESS)?

A Battery Energy Storage System (BESS) is a facility that stores electricity in stacks of battery cells for later use. It helps balance supply and demand, ensuring a stable and reliable power grid. When demand is high, stored energy is discharged, reducing pressure on the grid and lowering electricity costs.

How does BESS benefit the energy grid?

BESS supports the grid by storing excess electricity during periods of low demand and releasing it when demand is high. This stabilizes the system, prevents power outages, and helps integrate renewable energy sources like solar and wind by storing power when it’s generated and distributing it when needed.

Why is BESS important for renewable energy?

Renewable sources like wind and solar are intermittent – meaning they don’t always generate electricity when it’s needed. BESS bridges this gap by capturing surplus power and making it available on demand, ensuring a more consistent and efficient renewable energy supply.

Is BESS safe?

Yes. BESS facilities are designed with multiple safety layers, including fire suppression systems, temperature controls, and remote monitoring. Strict regulations and industry standards guide their installation and operation to ensure safety for the community and the environment.

Where will the energy stored in BESS come from?

BESS draws electricity from the provincial power grid, which includes a mix of generation sources such as hydro, nuclear, wind, and solar. It does not generate electricity on its own but optimizes how energy is used across the system.

Does BESS generate noise?

BESS facilities operate quietly, with noise levels comparable to a commercial air conditioning unit. Advanced design, strategic placement, and landscape features minimizes any potential sound impact on nearby homes and businesses.

How does BESS support local communities?

Beyond strengthening the power grid, BESS projects contribute to local economies through job creation, infrastructure investment, and community benefit programs. These facilities help ensure long-term energy reliability, reducing the risk of power disruptions for homes and businesses.

How long do BESS batteries last?

BESS systems typically have a lifespan of 15 to 20 years. Over time, individual battery units can be replaced or upgraded to maintain efficiency and performance.

What happens to the batteries at the end of their life?

When batteries reach the end of their useful life, they are either repurposed for secondary applications or recycled. Industry best practices focus on minimizing waste and maximizing material recovery to support a circular economy.

Who regulates BESS projects?

BESS projects in Ontario are regulated by the Independent Electricity System Operator (IESO), along with provincial and municipal authorities. These regulations ensure safety, environmental responsibility, and alignment with local energy needs.

Will BESS reduce electricity costs for consumers?

BESS helps lower costs by improving energy efficiency and reducing strain on the grid during peak hours. By making electricity more available when demand is high, it minimizes the need for expensive, carbon-intensive power generation.

How does BESS help reduce emissions?

By storing energy from clean sources and reducing reliance on fossil-fuel-powered generation during peak demand, BESS lowers greenhouse gas emissions. This supports Canada’s commitment to reducing carbon output and transitioning to a more sustainable energy future.

How will security be managed?

BESS facilities being built by Evolugen will be monitored 24/7, with limited access to the site.
