Visual Impact Assessment Griffith Energy Storage Project 3.0 PROJECT DESCRIPTION 3.1 Description of the Project The Applicant proposes to construct and operate a 400-MW battery energy storage system (BESS), substations,and associated infrastructure on approximately 20 acres of a 106-acre site of privately owned land (Figure 2,Site Plan). The Project would contain pad-mounted energy storage units,in addition to inverters,supervisory control and data acquisition equipment,a collector substation,and an interconnection gen-tie line to the Tesla Substation.The Project would also include related and supporting facilities,such as onsite service roads,gates and security fencing,and temporary laydown and construction areas. Construction is expected to begin as early as 2023 and be completed in approximately 12 months. 3.1.1 Battery Energy Storage System 3.1.1.1 Batteries Individual lithium-ion,or similar technology, battery cells form the core of the BESS.The battery cells are assembled either in series or parallel connection in sealed battery modules.The battery modules would be installed in self-supporting racks electrically connected either in a series or parallel to each other.The individual battery racks are connected in series or parallel configuration to deliver the BESS power rating.At this time,the battery technology for the Project has not yet been finalized;the battery type would be selected based on the technology available at the time of construction. Enclosure Units and Controller Multiple self-contained storage system enclosures would house the batteries, described above, as well as the BESS controller(Figure 3).The BESS controller is a multi-level control system designed to provide a hierarchical system of controls for the battery modules, power conversion system (PCS), medium-voltage system,and up to the point of connection with the electrical grid.The controllers ensure that the BESS effectively responds to grid emergency conditions and provides a secondary safety system designed to safely shut down the facility.The storage system enclosure would also house required heating,ventilation,and air conditioning(HVAC) and fire protection systems. Heating,Ventilation,and Air Conditioning Units Each enclosure would be equipped with HVAC systems for thermal management of the batteries.The power for the HVAC system would be provided through a connection to the onsite station service transformer with connection lines installed above and/or below ground. Fire Suppression Systems Fire detection measures would be incorporated in the Project design in accordance with National Fire Protection Association safety standards. OTETRA TECH 4 August 2023
