FAQS

Do energy storage sites have different safety codes and standards?

Yes, different safety installation codes and standards are used for energy storage sites with large utility-owned systems where the inverters and batteries are housed in separate locations and the entire project is often far from other buildings. For instance, the 1,600-MWh setup at Moss Landing in California follows these specific codes and standards.
