Story 1: The Hornsdale Power Reserve Battery Tunnel
The Hornsdale Power Reserve battery tunnel in South Australia is one of the largest battery storage facilities in the world. It has a storage capacity of 150 megawatt-hours and can power 90,000 homes for up to six hours. The battery tunnel has helped to integrate renewable energy into the South Australian grid and reduce greenhouse gas emissions.
Lesson Learned: Battery tunnels can be used to store large amounts of energy from renewable sources and help to balance the grid.
Story 2: The Nevada Gold Mines Battery Tunnel
The Nevada Gold Mines battery tunnel is a 50-megawatt-hour battery storage facility that helps to power the mining operations at the Cortez Mine. The battery tunnel has reduced the mine's reliance on diesel generators and saved millions of dollars in fuel costs.
Lesson Learned: Battery tunnels can be used to reduce greenhouse gas emissions and lower operating costs for industrial facilities.
Story 3: The Tesla Megapack Battery Tunnel
The Tesla Megapack battery tunnel at the Moss Landing Power Plant in California is a 182.5-megawatt-hour battery storage facility that helps to balance the grid during peak demand. The battery tunnel has reduced the need for fossil fuel-fired power plants and helped to avoid blackouts.
Lesson Learned: Battery tunnels can be used to shift energy consumption from peak hours to off-peak hours and reduce strain on the grid.
