1.
Reselect the site if the safety distance for a site cannot meet the requirements of relevant national
standards.
2.
If no more suitable site is available, you are advised to install firewalls that provide at least 3-hour
protection. In addition, the space requirements for equipment transportation, installation, and
maintenance must be considered.
3.
According to T/CEC 373-2020, the length and height of the firewalls should exceed the outer
contour of the ESS container by 1 m, respectively. According to NFPA 855-2020 Standard for the
Installation of Stationary Energy Storage Systems, when there are independent firewalls that provide
1-hour protection, the distance can be 914 mm.
Do not select the sites that are not recommended by industry standards and regulations,
including but not limited to the following areas:

Areas with sources of strong variation, loud noises, and strong electromagnetic
interference

Areas with dust, oil fumes, harmful gases, and corrosive gases

Areas with corrosive, flammable, and explosive materials

Areas with existing underground facilities

Areas with adverse geological conditions such as rubbery soil and soft soil layer, or
prone to waterlogging and land subsidence

Under a reservoir, water landscape, and water room
If areas prone to waterlogging cannot be avoided, install water blocking and drainage facilities or raise
the ground.

Areas prone to earthquakes

Areas prone to debris flow, landslide, quicksand, karst caves, and other direct hazards

Areas within the mining land subsidence (dislocation) zone

Areas within the scope of blasting hazard

Areas prone to flood due to a dam or levee failure

Protection areas for important water supply sources

Protection areas for historic relics

Populated areas, high-rise buildings, and underground buildings

Urban intersections and high traffic areas
Requirements for flood and waterlogging prevention in site selection:

The site design elevation of a large-scale electrochemical energy storage system (power
≥ 100 MW) should be higher than the flood level with a probability of 1% or the
historical highest waterlogging level.

The site design elevation of a medium- or small-scale electrochemical energy storage
system (power < 100 MW) should be higher than the flood level with a probability of 2%
or the historical highest waterlogging level.

If the site design elevation cannot meet the preceding requirements, change the site
location or take different flood and waterlogging prevention measures based on the site
requirements.

For energy storage plants prone to wind and waves from rivers, lakes, and seas, the
elevation of flood prevention facilities should consider the wind and wave height with a
probability of 2% and an additional safety height of 0.5 m.
