FAQs about Requirements for spacing between containers in energy storage power stations
What does NFPA 855 mean for energy storage systems?
Specifically, we're focused on spacing requirements and limitations for energy storage systems (ESS). NFPA 855 sets the rules in residential settings for each energy storage unit—how many kWh you can have per unit and the spacing requirements between those units. First, let's start with the language, and then we'll explain what this means.
How much energy can a ESS unit store?
Individual ESS units shall have a maximum stored energy of 20 kWh per NFPA Section 15.7. NFPA 855 clearly tells us each unit can be up to 20 kWh, but how much overall storage can you put in your installation? That depends on where you put it and is defined in Section 15.7.1 of NFPA 855.
