Fears renewable energy batteries will put bushfire-prone town at 'risk' | 7.30

Key Concepts

• Battery Energy Storage Systems (BESS)
• Lithium-ion batteries
• Thermal runaway
• Battery Management System (BMS)
• Fire risk and safety
• Community consultation
• Environmental concerns (water contamination)
• Development Facilitation Program
• CFA (Country Fire Authority) guidelines

Proposed Battery Developments in Darang

• Two battery energy storage systems (BESS) are proposed for Darang, a small town in Victoria, Australia.
• The projects are proposed by Mint Renewables and Trina Solar.
• The purpose of the batteries is to store renewable energy (wind and solar) for later use in Melbourne.
• The local community of Darang is largely opposed to the projects.

Community Concerns

• Fire Hazard: Residents fear the risk of fire, citing the town's history of bushfires (1968, 2003, 2006, 2009 Black Saturday).
• Proximity to Homes: The proposed locations are close to residential properties, with one battery being 450m from Sharon and John Makavoy's front door.
• CFA Capabilities: Concerns that local CFA volunteers are not equipped or trained to handle lithium-ion battery fires, which involve toxic chemicals.
• Water Contamination: Theresa Hicks, a dairy farmer, is concerned about potential water contamination from fire extinguishing agents or toxic fumes, as residents rely on springs for livestock and families.
• Impact on Lifestyle: Sharon, a retired school teacher, expresses frustration at having to dedicate her retirement to fighting the projects.

Company Responses

• Trina Solar:
  • John Zong, Trina Solar's country manager, acknowledges community concerns but compares the situation to parents forcing children to go to school.
  • He states that they have received and addressed community submissions.
  • Trina Solar has submitted a risk management plan prepared by fire risk consultants and claims to have consulted with the local CFA.
• Mint Renewables:
  • Declined an interview but stated that the project will only proceed if granted a permit by the Minister of Planning and if they follow CFA guidelines.

CFA Involvement

• CFA acting chief officer Gary Cook confirmed that the CFA has been consulted on the projects and will continue to work with the developers.
• He added that fire safety at large-scale renewable energy facilities is a focus for CFA.

Technical Aspects of Lithium-ion Battery Fires

• Dr. Matthew Priestley, a battery and energy expert, states that grid-scale battery fires are rare but generally due to a fault.
• He explains the concept of "thermal runaway," where the battery temperature exponentially increases to over 500°C, making the fire difficult to extinguish.
• Lithium-ion batteries have a Battery Management System (BMS) to monitor the health of the battery and prevent overheating.

Moss Landing Example

• A fire at the Moss Landing lithium-ion battery plant in California is cited as a real-world example of the potential dangers.
• The fire forced the evacuation of over a thousand people, and the cause is still under investigation.

Government Involvement

• National Senator Bridget McKenzie has voiced support for the Darang community.
• The battery projects are being reviewed by the state government's Development Facilitation Program, which fast-tracks projects that contribute to Victoria's economy.
• The local council voted to formally oppose both the Mint Renewables and Trina Solar battery projects.
• Victorian Planning Minister Sonia Kilkenny and Victorian Energy Minister Lily Damrosio declined interviews.

Notable Quotes

• Sharon Makavoy: "These batteries do nothing for us except create fire hazard and problems."
• John Zong (Trina Solar): "...it's just like how kids don't you know my kid doesn't like go to prep but then I have to tell them that hey you know going to prep is about you know to it's part of your journey to actually learn and study and and to become an adult right"
• Theresa Hicks: "...we've got subterranean water a lot of underground streams that all of these toxic chemicals can leech into and most of the residents around here rely on springs to feed livestock to feed their families we do here and we can't have them being contaminated..."
• Sharon Makavoy: "I don't get to work with my husband on the farm it's just like it's all consuming but then I go if we lose this battle I gave it my best shot."

Synthesis/Conclusion

The proposed battery energy storage systems in Darang have sparked significant opposition from the local community due to concerns about fire risk, environmental impact, and the adequacy of safety measures. While the companies involved emphasize their commitment to safety and community consultation, residents remain skeptical and are actively fighting the projects. The situation highlights the challenges of balancing renewable energy development with local concerns and the importance of thorough risk assessment and community engagement. The outcome of the state government's review will determine the future of these projects and their impact on the Darang community.
