EPA's Role at Moss Landing: What does the battery removal process involve?
Return to: Frequently Asked Questions
EPA oversees Vistra to ensure Vistra properly handles and removes the batteries.
Key activities:
- Remove batteries from the building for inspection and testing on site.
- De-energize and treat batteries for shipment. De-energizing involves reducing the charge in the batteries enough to prepare them to be safely transported for recycling.
- Safely recycle batteries off-site.*
*Some batteries that cannot be recycled due to damage will be processed on site and disposed of as hazardous waste at EPA-approved disposal facilities.
What is battery delinking and what does it do?
Battery “delinking” is when cables connecting different batteries are disconnected.
At Moss Landing, batteries were disconnected from one another. They were also disconnected from the rack holding the batteries in the energy storage system.
Disconnecting the batteries from one another lowers the risk of fire.
