Residents' Questions
-
What fire risks does the project pose, and how is Evolugen working to prevent these risks?Fire risk is very low for BESS facilities and, as is the case with any electrical equipment, that risk is easily mitigated when managed properly. We are committed to building our projects to the highest standard of safety with industry-leading equipment to be managed and operated by battery storage experts. In addition, we work closely with local firefighting professionals, safety experts, and City officials throughout the development and design of the project to coordinate detailed emergency response planning. Brookfield is a global leader in energy project development, including BESS. We successfully operate BESS facilities across three continents, including North America. With our earliest installation coming online in 2013, we’ve experienced no fire incidents.
-
Sensors for lithium off-gases of the storage system will be monitored from another province.The most up-to-date technology will be used to maintain and monitor South March BESS in real time, 24/7. A direct notification system to Ottawa Fire Services and the Evolugen operations team is in place to allow for immediate response to any alerts.
-
Will more batteries be added as the efficacy of the initial batteries deplete? Does this increase the risk of fire?Battery modules will be replaced as battery efficiency decreases over time. The replacement of battery modules is key to maintaining the system’s safety and reliability. The current system design is coordinated closely with Ottawa Fire Services and incorporates any future addition of BESS containers within the existing project footprint.
-
What is the proximity to forested areas?We will meet all provincial and municipal setbacks, including the imposed buffer to any forested areas.
-
Should the January 2025 Moss Landing fire in California be a cause for concern for these BESS facilities?The fire at the California battery facility should not be seen as a reason for concern when it comes to our BESS facilities. The Moss Landing fire was attributed to several factors: The battery chemistry used was Nickel Manganese Cobalt (NMC) technology, which is proven to be less safe. The containers were housed inside an enclosed space, reducing ventilation and increasing the risk of propagation, as we saw. The facility lacked the new and improved safety standards that containerized, LFP batteries undergo, such as large-scale burn testing. It was a first-generation BESS designed over seven years ago, since which time safety standards have drastically improved.
-
Some roads only have one road in and out. Does the project’s emergency planning take this into account?All local context, including emergency evacuation routes for nearby residents, is considered as part of a project’s Emergency Response Plan, which is prepared in consultation with the Ottawa Fire Services. While we are committed to preparing for any scenario, we reiterate that the probability of a potential fire incident is extremely low, as is the severity should one occur. There have been hundreds of burn tests done on these facilities, including with our preferred battery selection. In addition to the fact that these units are extremely difficult to intentionally set fire to, the testing and real-world incident data show that any fires are contained within a project site.
-
What fire prevention strategies will be applied at the facility?All batteries will be equipped with a battery management system to ensure they are operated within safe operational thresholds. The battery management system is designed to shut the system down before an incident can occur. In consultation with City of Ottawa Fire Services and international experts, our project will incorporate state-of-the-art preventative measures, including: Multiple sensors, including on each individual battery cell, being monitored 24/7 from our Networks Operation Centre (NOC) Built-in real-time temperature control systems Ventilation panels Insulated containers An outdoor, well-ventilated configuration
-
Please describe the emergency response process to fight a fire. Is there a successful response to a fire other than to let it “burn” out?In the highly unlikely event of a fire, the fire alarm system will notify the Ottawa Fire Services (OFS). The OFS will respond to and monitor the event. In consultation with OFS and the Energy Safety Response Group, industry best practice is to allow the fire to consume itself while maintaining the safety of the community and first responders. This has been proven to be a very manageable approach, and the safest one.
-
Has there been a controlled fire on a BESS where the entire storage area burned? If not, why not? If so, what was the outcome? How much of the toxins leached into the ground or the air?Yes, large-scale burn tests have been completed on most battery storage products, including our preferred battery selection. Tests on our preferred battery have shown that a fire in one battery container does not spread to adjacent containers. Air quality monitoring and soil testing conducted throughout demonstrate that the resulting air quantities fall well within acceptable limits.
-
Please provide all incidents with facilities similar to this one where an incident detrimental to the environment occurred.Please share: i. The environmental consequences of such incidents. ii. The responses to such an incident including successes as well as failures. iii. The dimensions of the containment area. iv. Details of studies that have monitored the long-term impact of all such incidences. We evaluated numerous containerized LFP battery vendors and prioritized fire safety as one of our primary criteria. As a result, the facility we are proposing is not comparable to the select few older facilities with reported fire incidents. Our preferred battery vendor has experienced no fire incidents with over 25,000 MWh deployed across facilities globally.
-
Are local fire departments trained to handle incidents such as battery fires or chemical leaks? How will you guarantee that the ground water or the air are protected from potential contamination?City of Ottawa Fire Services and their highly trained firefighters are well equipped to handle battery fire and chemical spill incidents. In controlled burns under worst-case scenarios, all LFP battery fires exhausted themselves. The project has secondary containment in each individual container, and our stormwater management system will adhere to or exceed all municipal and provincial requirements. In his public remarks at a meeting of Ottawa City Council’s Agricultural and Rural Affairs Committee, Fire Chief Paul Hutt noted, “I can share with members of the committee and the public, it goes without saying, but we have very highly trained and skilled personnel with Ottawa Fire Services; we have modern technology and equipment for response.”
-
What is the risk of particulates contaminating the air during a BESS fire?Large-scale burn tests have recently been conducted on the equipment that we are looking to purchase, and these tests have shown there is no risk to the public from air contamination. We have also conducted preliminary air dispersion modelling with a third-party consultant to better represent the local context, which confirmed that there is no risk to the public from air contamination. The results from both studies will be released publicly once finalized.
-
Will details on the fire-suppression technology/chemistry that will be used and its effect on the environment in the event of a fire become publicly available? Who is responsible for cleanup following a fire?All batteries will be equipped with a battery management system to ensure they are operated within safe operational thresholds. The battery management system is designed to shut the system down before a failure that could lead to a fire. In consultation with City of Ottawa Fire Services and international experts, we are looking to integrate: Multiple sensors, including on each individual battery cell, being monitored 24/7 from our Networks Operation Centre Built-in real-time temperature control systems Dry-pipe fire suppression systems Fire hydrants Ventilation panels On-site reservoirs Run-off containment systems Constant environmental monitoring including groundwater, air, and soil In the highly unlikely event of a fire, the fire alarm system will notify the Ottawa Fire Services (OFS). OFS will respond to and monitor the event. In consultation with OFS and the Energy Safety Response Group, industry best practice is to allow the fire to consume itself while maintaining the safety of the community and first responders. This has been proven to be a manageable and safe approach. OFS is responsible for the immediate emergency response, and Evolugen is required by law to remove impacted equipment and debris.
-
Will the monitoring of sensors and cameras be done on a 24/7 basis and by humans?The remote monitoring is carried out both by third parties and from our Network Operations Centre (NOC), 24/7.
-
Do projects pose a risk to wildlife, including some endangered species?The project will adhere to all requirements related to the protection of local wildlife and, where practical, we will work with the community to incorporate design features that address particular concerns unique to the local ecosystem.
-
In the case of South March BESS, does the project’s proximity to an area designated as environmentally sensitive and significant pose environmental concerns for that area?The project will adhere to all requirements related to the local environmental context and, where practical, we will work with the community to incorporate design features that address particular concerns unique to the local ecosystem. We've engaged environmental groups to ensure any concerns are addressed. Our project exceeds the recommended setbacks to Provincially Significant Wetlands, one of the many advantages of the South March BESS location.
-
Will electromagnetic fields (EMFs) associated with a high voltage infrastructure like BESS facilities affect the navigation and communication abilities of birds and bats?Projects will adhere to all requirements related to the local environmental context and, where practical, we will work with the community to incorporate design features that address particular concerns unique to the local ecosystem. One of the benefits of BESS is its compact footprint. These sites will have no more impact than a single high-voltage utility substation.
-
Do projects pose a soil contamination threat?For containerized LFP BESS, no harmful impacts to soil have been recorded, even after the select few fire incidents. Sampling for oil contamination is highly regulated under the Environmental Protection Act in Ontario. We have and will continue to adhere to best practices related to soil contamination during construction and operations to ensure safety and reliability.
-
Do projects pose a contamination risk to local water resources?For containerized LFP BESS, there have been no harmful impacts to water recorded after any fire incident. Projects will have secondary containment in each individual container, and our stormwater management system will adhere to or exceed all municipal and provincial requirements.
-
What risk is there of contamination as a result of an explosion at the project?The risk of explosion is negligible because the system is designed to prevent the buildup of combustible gases through both active and passive ventilation systems. Large-scale burn tests have recently been conducted on the equipment that we are looking to purchase, and these tests have shown there is no risk to the public from air contamination. We have also conducted preliminary air dispersion modelling with a third-party consultant to better represent the local context, which confirmed that there is no risk to the public from air contamination.
-
Will South March provide the documented studies of the prevailing winds at this location and the environmental consequences the winds would have in exacerbating any environmental event?Air Quality: The maximum predicted one-hour average concentration of carbon monoxide (CO) complies with Ontario’s Ambient Air Quality Criteria. Additionally, the maximum predicted concentrations of hydrogen fluoride (HF) and CO comply with the applicable air limits. OHS: Modelling indicates that the applicable Immediately Dangerous to Life or Health (IDLH) limits are not exceeded on site or beyond the BESS fence line. Public Health and Safety: The maximum predicted HF and CO off-site concentrations are within the applicable three tiers of Acute Exposure Guideline Levels (AEGLs) for all averaging periods. Risk Summary: The public’s risk of exposure is insignificant or at the de minimis level.
-
What is the risk of groundwater contamination from firefighting water runoff during a BESS fire?The first line of defence is always to prevent an incident from happening. Before any construction, we will conduct all the required studies and put in place stringent safeguards above industry standards to mitigate any risk. In the unlikely event of a fire incident, water will only be used to cool down adjacent containers and potentially used in a fog pattern to manage smoke. However, the project also has secondary containment in each individual container, and our storm water management system will adhere to or exceed all municipal and provincial requirements. For containerized LFP BESS, there have been no harmful impacts to soil or water recorded after any fire incident.
-
On the South March BESS, what are the drainage implications in our wet seasons or drought years? What will be the effects on the ecological system given that this proposed site is near the Carp Ridge / Escarpment?The South March BESS facility will have its own dedicated and isolated stormwater management system. The drainage system is designed to contain all surface water on site, assuming the most severe seasonal weather over the last 100 years. We are engaged in discussions with the Mississippi Valley Conservation Authority to ensure that all natural features are considered in our design.
-
Have detailed hydrogeological studies been performed?Hydrogeological assessments are conducted by highly qualified engineers, and the details will be released when the results are finalized. These studies are required and must adhere to the appropriate bodies as part of our Municipal Site Plan and Zoning application.
-
How are you planning to cool the batteries? If water is used, how will that affect the flow rate in our wells?The batteries have an internal, closed-loop cooling system that does not draw on the community water supply.
-
How will the quality of our groundwater be affected if they are withdrawing massive amounts? Will we have to add more water treatment equipment?We are not withdrawing any groundwater from the community.
-
How would a potential leak from the BESS affect wildlife in the area?Projects will adhere to all requirements related to the local context and, where practical, we will work with the community to incorporate design features that address particular concerns. The risk of a leak is extremely low due to 24/7 monitoring and routine maintenance being performed on the equipment. In the unlikely event that there is an issue, each individual container has secondary containment, and the site has an isolated storm water management system that will adhere to or exceed all municipal and provincial requirements.
-
How close is the South March BESS facility to the Environmentally Protected Area (EP3)?We are adhering to all zoning requirements set forth by the City of Ottawa. The nearest Provincially Significant Wetland is over 600m from the project, well outside the imposed setbacks. A high-voltage transmission corridor that spans 100m separates our project from the nearest EP3 zoned land, and we are an additional 100m from this electrical infrastructure.
-
What is "secondary containment”?Each individual container is equipped with secondary containment. If there is an issue with the internal components, the bottom of the container is sealed to prevent anything from spilling out. The battery cells themselves are a dry type, not liquid-filled. The chiller has some fluids that are more relevant to the containment. The entire site also includes grading and a drainage system, as well as an impermeable barrier that captures potential runoff in an isolated retention pond.
-
Who will ensure the flow of surface water will remain the same?Through the civil engineering design and site plan application, we are obligated to ensure natural waterflows are segregated from our drainage system and that the flow rates of any watercourses are maintained.
-
Are you taking extra precautions to protect groundwater?Beyond the multiple layers of containment within the battery containers, we are undertaking the installation of an impermeable geomembrane barrier underneath the batteries to prevent contamination and leeching. Coupled with a robust, adequately sized stormwater management system with the ability to isolate and contain all water on site, these systems will go above and beyond the typical protections for these types of projects.
-
What is the proposed location of the South March BESS facility?2555 Marchurst Road and 2625 Marchurst Road are a combined 200 acres. Our project will take up 10 acres, representing about 5% of the land. Several hundred metres in, over the ridge, there is an open field next to the transmission corridor leading to the South March substation. Find an aerial image of the site at: www.getchargedottawa.ca/south-march-bess.
-
How visible will the South March BESS site be to local residents and visitors?A main advantage of the South March location is that the site will not be visible from public roads. We will also be incorporating a natural earth berm and planting trees around the site, further decreasing any visibility. Where practical, we will consider all requests of the community regarding the design and operations of the South March project.
-
What confidence do you have that the approved setbacks from forested areas will be enough to safely avoid a dangerous fire situation?Our site layouts and containers’ safety technology are designed such that a fire incident would be contained within the project boundary and fence line, and safely managed by firefighting services. Projects will adhere to all requirements related to the local context and, where practical, we will work with the community and Ottawa Fire Services to incorporate design features that address particular concerns regarding setbacks from the dripline of a forested area. All of the local context is considered as part of an Emergency Response Plan that is being prepared in consultation with Ottawa Fire Services.
-
Why do BESS facilities need new land and use not existing hydro corridors?Generation facilities are not permitted to be installed within the Hydro One Network Inc (HONI) hydro corridors.
-
Why does it make the most sense to install BESS in a country setting?Our sites adhere to all the zoning and permitting requirements specified by the City of Ottawa and the province. Other site selection factors include proximity to existing transmission, setbacks from homes, visibility, and more.
-
Is the South March site in the seismic-sensitive area?Based on site investigations and national building codes, this location would not be considered a seismically hazardous area and is safe to build on.
-
Given that other BESS sites are relatively far from transmission lines, why is its importance emphasized when explaining South March’s location?It is much more beneficial to build battery storage adjacent to transmission infrastructure. This decreases local impacts and increases the reliability of the system. By increasing the work required to construct a transmission line, you increase impacts to the local area, including traffic flows, visibility, and more. The South March site adheres to all the zoning and permitting requirements specified by the City of Ottawa and the province. The site was selected due to its proximity to the existing transmission line that serves the South March substation, generous setbacks from homes, and low visibility, among other factors.
-
Are there any plans for any kind of future expansion and if so, what are they? and what approvals/guarantees do you already have from the relevant authorities for such expansions?There are no plans or pathways to expand the sites under the Independent Electrcity System Operator’s (IESO’s) 20-year, LT1 capacity contracts. The IESO will soon be launching the forthcoming LT2 procurement to secure additional capacity for the province, which will utilise new sites and have no relation to South March or Trail Road.
-
Will the containers be placed on a concrete pad in an effort to contain spills?The structural foundations will be designed according to the project life and sound engineering practice. We are looking to utilize low-impact helical piles, or concrete piers that are secure and reduce impact on the land. These decisions will be informed by ongoing consultations with local stakeholders. Projects have secondary containment in each individual container, and our stormwater management system will adhere to or exceed all municipal and provincial requirements.
-
How will the site protect against criminal acts like vandalism?Project sites will have a fence that stretches for the entire perimeter of the facility.
-
What happens in the event of an internet and/or cell service outage?A reliable service network will be installed as part of the facilities' construction to allow secure internet and cellular service. Site protection is done independently of an internet line or cell connection, and in the case of fault or failure, the site is placed in a safe state and disconnected from the transmission grid. In the instance of any issues with remote monitoring, the sites are designed to shut down until communications are re-established.
-
How will rainwater and drainage on the site be managed?The BESS facilities will have their own dedicated and isolated stormwater management system and on-site water reservoir. The drainage system is designed to manage all surface water on site, with design preparations for the most severe seasonal weather over the last 100 years.
-
How will sites be secured if tornados were to occur?The containers are heavy and anchored to the ground. There is no prospect of them being affected by a tornado.
-
What techniques will be applied to ensure the safety of the site in the event of an earthquake?The project areas have been assessed and do not pose a significant risk in the event of an earthquake. The designs consider higher levels of resiliency and will be able to withstand reasonably sized earthquakes. These considerations include appropriate foundation design and anchoring.
-
If a fire originates in a neighbouring wooded area, how will the heat produced by that fire affect the stability of the batteries? Can the cooling system keep up?Backed by burn testing involving temperatures significantly higher than a forest fire, the containers are designed so that if a fire were even to be adjacent to their walls, it would still not cause the container to overheat or propagate.
-
How is stormwater from the site kept separate from natural water sources?The BESS facilities will have their own dedicated and isolated stormwater management system. The drainage system is designed to contain all surface water on site, assuming the most severe seasonal weather over the last 100 years.
-
What zoning permits the installation of 250MW BESS?As per the City of Ottawa, Considerations for zoning must consider their intended use, preferred location and size. The Zoning By-law therefore needs to distinguish between a BESS facility intended as a standalone use and which is connected directly to the electrical grid and a BESS that is accessory and supports principal residential and non-residential uses. 7) Non public utility battery energy storage systems (BESS) are permitted as a principal use in the following land use designations: a) Rural Countryside designation and Rural Industrial and Logistics designation. b) Mixed Industrial and Industrial and Logistics designations in the Inner Urban, Outer Urban and Suburban Transects.
-
What will happen to housing values in nearby neighbourhoods?The factors that could affect nearby housing values as a result of the facility actually point to a potential increase in housing values. The facility, for instance, will support local development in the area and provide a reliable and safe supply of electricity, both of which often drive increases in property valuation. Further, mitigation measures will be implemented in accordance with the recommendations of the MTF Class EA, which will include input from the local community. These could include, for example, tree planting, vegetation buffers, decorative / community-friendly fencing and/or an earth berm along the perimeter of the site to visually mask the facility.
-
Will home insurance rates increase for nearby properties?There is no data that shows that BESS projects have an impact on home insurance.
-
Will the facility be lit at night? If so, how bright?There will be no active lighting on site. There will be purpose-built lighting that will only be used should a technician need to come to the site, but it will remain dark at all other times.
-
How much noise will be generated by this facility?Noise will not exceed 40 decibels at the nearest residence and will reduce drastically as you move further from the site. The noise will be comparable to that of a fridge, and would be completely inaudible beyond the setback distance.
-
Will the site impact local hydro rates?BESS projects are the most affordable option available to meet the province's rapidly growing power needs. These BESS projects were procured through the IESO's Long-Term (LT1) procurement to meet this need. This procurement saw over 41,000 MW of bids competing for 1,000 MW of contracts. The high degree of competitiveness helped drive down bid prices, resulting in the lowest-ever price of procured capacity in the province, with other resource types competing in this procurement. In comparison to natural gas first-generation projects, which submitted an average bid price of $1,681 per MW/business day, BESS projects submitted $672 per MW/business day. This means that delivering the 250 MW of capacity proposed by South March BESS would be 60% more expensive through a gas plant, with a larger footprint.
-
What benefits will the BESS site have in the community in the long run?The benefits in 10 or 20 years from now will be more reliable energy for you and the next generation, reduced electricity rates, fewer blackouts, lower emissions, a skilled workforce able to adapt to these types of projects, local support through Community Development Funds, and more.
-
On the South March BESS, what efforts have been made to consult the community about this project?We are still actively consulting the community. We have previously held an open house, industry events, and safety training. We’ve knocked on doors in the community and delivered informative postcards on the project. We’ve also extended our online presence and public awareness campaign. This FAQ covers topics directly sourced from questions we’ve received from the public. The South March location was identified as one of the best sites after assessing dozens of other potential sites. Extensive due diligence to select this site enabled us to have the maximized setbacks, less impact to the environment, and greater local benefit by tapping into the South March substation.
-
What other forms of consultation will take place?We have engaged in consultation with numerous industry professionals and community partners. Indigenous consultation with the Algonquins of Pikwakanagan Community consultations with local residents that continue to take place Fire safety consultations with City of Ottawa Fire Services and the Energy Safety Response Group, including hosting training sessions with local firefighters Environmental consultations with experts and local advocacy groups Planning consultation with City staff Construction consultations with experienced and trusted engineering firms
-
What information will be shared with the public and how will it be shared?All city permits, site plan studies, public letters, and environmental evaluations will be made public and will be primarily shared through our project website. We are also accessible through our GetCharged Ottawa Facebook Page, or by emailing us directly at info@GetChargedOttawa.ca We will continue to communicate with residents in a number of ways, including public events, letters in the local news, and face-to-face conversations with residents.
-
Why did you host an open house for the South March BESS over a town hall format?Our open house provided an opportunity for our team and our technical experts to connect with local residents to answer questions and solicit feedback on the BESS project design. We presented our initial design layouts and gather meaningful input from neighbours to help us advance to the next stage of project detail – the types of conversations that are best enabled through an extended, face-to-face dialogue, with maps and photos.
-
How are you incorporating feedback from the community?Below are three major revisions to our project based off direct consultation with the community: Site Selection Based on consultation with the public starting in Fall 2023 and leading up to 2025, we located a better site more aligned with the feedback we had heard from residents such as the amount of required tree clearing, presence of wetlands and proximity to residents, and made the decision to move the project. The new South March project had no wetlands, minimal tree presence and fewer neighbours. Fire Safety Preliminary consultation with Ottawa Fire Services recommended installing fire hydrants, a dry pipe system and on-site reservoir. We’ve incorporated those elements into our system design. Protecting Groundwater We’ve heard from residents with concerns about groundwater contamination. Although there is no reported evidence of a BESS ever contaminating groundwater, we have taken extra precautions including multiple layers of containment. The internal sections of the battery have containment, the whole unit itself is contained, and more recently, we’ve taken the added measure of deploying an impermeable geomembrane barrier underneath the site, connected to a stormwater management system that can be completely isolated from the existing watercourses in the event of an emergency, even further reducing any risk of groundwater contamination.
-
What is the source of the power that will be stored?BESS will draw electricity from the provincial power system, connecting through a Hydro One transmission connection. Typically drawing overnight, much of the intake will be from generation assets in Eastern Ontario, namely hydroelectric, nuclear, and wind sources.
-
How much power will the South March BESS facility discharge during a power failure and for how long? Is this the main purpose of the site?The South March BESS will be charged during off-peak hours using Ontario's energy grid and will be able to discharge up to 1,000 MWh for consumers, including those served by the South March substation. In the event of an outage or a grid event, the IESO would be responsible for dispatching power. A few real-world examples of BESS performing during power outages include: In Parent, Quebec last year, a battery provided power to a remote community during planned and unplanned outages. During southern Alberta’s power outage in January 2024, BESS installations were the highest-performing energy asset class with 100% deployment. Following major winter and summer outages in Texas, the state has installed over 11 GWh of BESS to relieve outages and restore power after incidents.
-
What barriers are in place to physically contain any leakage from BESS? How will that be remediated?Projects will adhere to all requirements related to the local context and, where practical, we will work with the community to incorporate design features that address particular concerns. The risk of a leak is extremely low due to 24/7 monitoring and routine maintenance being performed on the equipment. In the unlikely event that there is an issue, each individual container has secondary containment, and the sites have an isolated stormwater management system that will adhere to or exceed all municipal and provincial requirements.
-
What is the list of contaminants that we are dealing with on a day-to-day basis and in the event of a catastrophe?Evidence shows that in the event of fire incidents at some of these older facilities, there has been no overexposure to contaminants. In normal operations, there are no contaminants emitted.
-
Are there backup systems to heat or cool the batteries?The battery containers have self-contained mechanical heating and liquid cooling systems designed to maintain the battery at a safe operating temperature. Reserve capacity is built into the cooling system.
-
Will the containers be insulated and, if so, will the material used have the potential for negative environmental consequences?The insulation within the container is no different than what you may find in a typical house or building. It is non-combustible, fire resistant, and will not develop toxic smoke in the highly unlikely case it is exposed to a fire.
-
Do the batteries (containers) need to be heated in the winter?Yes, and the self-contained mechanical heating system will maintain the battery at a safe temperature.
-
What is the useful life of the facilities?The proposed projects would see a 20-year contract with the IESO starting May 2028. We are committed to returning the land to its original state at the end of the contract.
-
How many times will the batteries need to be replaced?Battery efficiency can decrease over time. We will monitor this at our BESS facilities and may make modifications to the systems as required to maintain a safe and reliable facility and energy supply, within the existing project footprint. This will not affect the project footprint as the area required to maintain batteries is already considered.
-
What is the disposal practice for the old batteries?At the end of their life, battery modules will either be refurbished for alternative uses or processed at domestic recycling facilities.
-
How much experience does Evolugen have in these installations?Our team has successfully operated 850 MW across numerous BESS facilities, with the earliest facility online since 2013. We have another 2200 MW of BESS facilities under construction, including a 500MW BESS site in Australia, and over 30 GWh of BESS in development.
-
What is the difference between lithium iron phosphate (LFP) batteries and lithium-ion batteries, and which will be used at South March?Lithium iron phosphate (LFP) batteries are a specific type of lithium-ion battery. Lithium iron phosphate is proven to be safer than the nickel manganese cobalt batteries. We can confirm that the South March project will use lithium iron phosphate (LFP) batteries.
-
Will third-party inspections of the containers, fire-suppression system, and sensors be carried out on a regular basis?Yes, this will be part of the operations and maintenance program.
-
Are there any sources you can provide about the sort of safety measures that are now standard for new BESS projects? Are there any sources from local projects?The latest technology for LFP containerized batteries is being proposed for these projects. These systems improve upon the older, lesser standardized systems of the past. You can find articles on the advantages of LFP batteries online. On safety measures locally, you can find the City of Ottawa FAQs on BESS safety here: https://engage.ottawa.ca/renewable-energy-generation/news_feed/battery-energy-storage-systems-bess-frequently-asked-questions-faq-s-on-fire-safety-2
-
What is the estimate of the number of shipping containers required to house the batteries at South March?South March BESS proposes to use roughly 250 containers within the project footprint.
-
What is the maximum number of hours that the South March BESS could discharge energy to the grid?The proposed LFP system would distribute up to 1000MWh back into the grid over a period of 4 hours, when it’s most needed to meet capacity and reduce costs. Technically, a BESS can discharge for a longer period at a lower capacity.
-
With respect to the safety of the proposed BESS facilities, how many similar facilities using the same technology have been constructed previously? What is the safety record of those facilities?We are in the process of finalizing our battery supplier and can confirm that our preferred choice of battery (this particular system uses a containerized system of Lithium Iron Phosphate batteries) has been deployed across 25,000 MWh of facilities globally without a single fire incident. Safety is our foremost priority in vendor selection.
-
Do you have any datasheets for the system being installed?While we have not completely finalized our choice of supplier, we are prioritizing safety above all else in our selection. Please refer to battery datasheets for the Sungrow PowerTitan 2.0, Powin Pod, and Tesla Megapack for comparison.
-
What are the physical specs of the facility (number of batteries, capacity of each battery, how many cells per container, AC to DC conversion efficiency, DC to AC conversion efficiency, storage efficiency over time)?Number of batteries: Depending on which supplier is selected, the number of individual battery cells within each unit will differ. We expect the project to deploy around 250 containers, each of which consists of 4-6 racks containing 4-8 modules, and the number of individual cells depends on supplier, but capacity will remain at ~5MWh. Capacity of each battery: Each container has a capacity of around ~5MWh. AC to DC conversion efficiency and DC to AC conversion efficiency: These batteries have a round-trip efficiency of 88-90% at the battery terminals. Storage efficiency over time and charging: While round-trip efficiency doesn’t degrade linearly over time, a rough estimate of 0.1% per year can be expected. Redistribution strategy/agreement with the city: We have a 20-year contract with the IESO for the South March BESS site which requires 1000 MWh (250MW over 4hrs) of daily distribution to manage the grid more efficiently and leverage the benefits of renewables i.e., reduced costs, reduced emissions. Specifications: The system will deploy 250MW of Lithium Iron Phosphate (LFP) batteries. The site will consist of approximately 250 secure containers placed on roughly 10 acres of land along the transmission line, connecting to the South March Transformer Station.
-
What batteries will be used?We have selected the Sungrow PowerTitan 2.0, and containerized LFP battery solution. It adheres to all North American standards of NFPA 855 and UL 9540 & 9540A, including extensive large-scale burn testing to run worst-case scenarios.

Is BESS really a more cost-effective strategy to combat power outages compared to upgrading our delivery infrastructure to minimize such failures?The primary use of BESS is to provide additional capacity to help meet Ottawa’s rapidly increasing peak demand. It will also help prevent outages. The project is complementary to major work in upgrading aging delivery infrastructure, including the IESO’s $600m investment in the Gatineau Corridor End-of-Life plan. You can learn more about this through a report completed by Dunsky Energy + Climate on the benefits of BESS: https://www.getchargedottawa.ca/report-optimizing-ottawa-power-grid

What insurance coverage will you provide for rectifying any damages caused by such a facility in the event of a fire or groundwater contamination?Although the likelihood of an incident is extremely low due to our robust design considerations, proven BESS technology, and our commitment to safety and quality throughout construction of the facility, we do have sudden and accidental pollution coverage under our liability master policy well in excess of $100,000,000.

Who will be responsible financially for any environmental incidents?Although the likelihood of an environmental incident is extremely low, Brookfield would assume responsibility should one occur.
-
How much public and/or private funding is being committed to finance this infrastructure?Brookfield Renewable is an entirely private company and an equity partner with the Algonquins of Pikwàkanagàn on these BESS projects. We will not be receiving any government grants, loans, or any other public funding, though we may be eligible for the federal government’s Clean Energy Investment Tax Credits (ITCs). 100% of the funding is private.
-
Who is going to bear the legal and financial liability for the equipment once the facility shuts down and components are moved offsite?Evolugen is responsible throughout the life cycle of the project, including decommissioning.
-
Who will financially benefit from these projects?Like all businesses, Brookfield expects to earn a rate of return on this investment. We have secured a contract to provide capacity to the Ontario electrical system through the highly competitive LT1 tender process and will earn additional revenue through the daily operations of the equipment. While these are privately financed, there will be a significant financial benefit to the local community, the Indigenous community, ratepayers, and the Province of Ontario. Amongst other beneficiaries, the project will unlock significant investment and job creation for energy-intensive companies at the Kanata North Technology Park and other employers. We are developing these projects in direct response to the IESO's call for increased capacity.
