NEC Energy Completes A 3.9MWh Grid Energy Storage System For Southern California Distribution Grid Support

This is the first energy storage system to support SCE's distribution grid and is providing many of the foundational aspects for future integrated distribution system deployment.

TOKYO and WESTBOROUGH, Mass., July 6, 2015-- NEC Corporation and NEC Energy Solutions ("NEC Energy") announced today that they have completed the installation of a 2.4MW, 3.9MWh GSS grid energy storage site in Orange, California for utility Southern California Edison (SCE). The system has successfully passed commissioning testing and is now available for full operation. This is the first energy storage system to support SCE's distribution grid and is providing many of the foundational aspects for future integrated distribution system deployment. The energy storage devices will be used primarily to provide grid support via circuit loading relief.

"Energy storage can provide the flexibility that provides the grid reliability that SCE's customers' expect," said Bud Collins, CEO of NEC Energy Solutions. "The system we've installed in SCE's territory will help them keep the high quality electricity service that their customers desire. Energy storage is becoming an ever-more common part of today's electric grid and our installation and commissioning process enables energy storage to be delivered just like any other piece of utility equipment. This latest installation was no exception."

Installation and commissioning of the system took about seven weeks from delivery of the first energy storage equipment to the site, and was completed by NEC Energy's grid storage integration team along with local contractors. The equipment was not housed in the standard shipping containers that have been the hallmark of most of NEC Energy's GSS installations around the world, but instead installed inside a custom enclosure designed to fit the site.

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.
