North America's Largest Battery Energy Storage System Now Operational

"The Tehachapi Energy Storage Project is a significant milestone for SCE and for energy storage in California"

SEOUL, South Korea--LG Chem has successfully delivered and commissioned the largest battery system installed in North America, a 32 MWh battery energy storage system in Tehachapi, CA.

In May 2013, Southern California Edison (SCE) selected LG Chem to deliver the turnkey 8 MW/32 MWh energy storage system for the Tehachapi Energy Storage Project (TSP), funded by SCE and the Department of Energy as part of the American Recovery and Reinvestment Act (ARRA).

As a complete energy storage system solution provider, LG Chem successfully delivered the turnkey project, the largest battery system in North America, including overall project and construction management, system engineering and design, and battery rack systems. Team members include ABB, Inc. for power conversion equipment and LG-affiliate LG CNS Corp. for construction services.

The objective of TSP is to validate the capabilities of a utility-scale lithium-ion battery energy storage system in providing grid support, facilitating the integration of renewable energy resources, and in providing market services. Over a two-year period, SCE will perform extensive field testing to verify the battery system's capabilities for transmission, grid, and market applications under thirteen specific operational uses.

"Successful completion and commissioning of SCE's TSP battery system has demonstrated LG's ability to deliver large-scale energy storage projects," said Mr. Young Soo Kwon, president of the Energy Solution Company at LG Chem. "Our continued collaboration with SCE over the next two years will provide valuable feedback on utilities' integration and operation of grid-scale storage systems. This will reinforce LG Chem's position as a leading energy storage partner to utilities and project developers."

"The Tehachapi Energy Storage Project is a significant milestone for SCE and for energy storage in California," said Doug Kim, director of Advanced Technology at Southern California Edison. "Grid-scale energy storage is an integral part of our company's Storage Portfolio Development Framework that will contribute to optimizing grid performance and integrating more renewable energy resources. This demonstration project will give us a significant amount of insight into the operational capabilities of large-scale lithium-ion battery storage."

LG Chem demonstrated its system engineering capabilities and the modularity and flexibility of its battery solutions by designing, engineering, and installing the utility-scale battery system to fit within a small footprint inside an existing 6,300 square foot facility at SCE's Monolith Substation in Tehachapi. The large-scale battery system is comprised of a total of 604 battery racks, 10,872 battery modules, and 608,832 individual battery cells – the same lithium ion cells installed in commercially-available vehicles sold by leading automotive OEMs to customers worldwide. The successful installation of the utility-scale energy storage system demonstrates LG Chem's capabilities for delivering large-scale, turnkey projects.

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
