31. Fire Safety
PROPRIETARY & CONFIDENTIAL
Preventative Measures:
◦ Battery Chemistry (LFP) is fire resistant; does not vent
combustible gases
◦ Outside, open-air installation
◦ Physical separation of inverters and batteries
◦ All products designed and certified to UL standards
◦ 24/7/365 Remote Monitoring
◦ Routine, preventative maintenance
Fire Suppression:
◦ Integrated, chemical aerosol fire suppression into the battery
container (i.e Stat-X System)
◦ Fire hydrants installed on 6-8’’water main at the parcel
◦ 20’ perimeter road for fire access
◦ Emergency Response Plans and training for local emergency
personnel provided by all battery manufacturers

33. Zoning / Permitting Requirement - SUP
PROPRIETARY & CONFIDENTIAL
◦ Currently site is zoned Single Family Residential –
7.2 District (SF-7.2)
◦ Angleton Substation located on land zoned
Residential
◦ Energy substations and transmission lines may
be approved through a specific use permit (SUP)
◦ Existing transmission lines on the property
◦ Based on feedback from Staff, Energy Storage
Project would require a SUP

36. Role of Energy Storage
PROPRIETARY & CONFIDENTIAL
◦ Traditional power plants (coal, natural gas) are
reaching the end of their useful life
◦ Renewable energy = increasingly intermittent
power supply
◦ Battery Energy storage systems (BESS) are
needed to serve as a balancing resource for
local utilities to manage the system
◦ Smooths power supply to match demand, shifts
energy to growing population centers, stabilizes
power quality and frequency across
transmission lines
