Battery Energy Storage System
2MW Battery Storage System
December 5, 2016
Project Scope and Description
• Install a new Battery Energy Storage System
(BESS) next to the new Grandview Substation.
• Build a new 69kV transmission line to connect
the BESS to the existing Kellogg switching
substation at the UOC.
• This BESS will store energy to mitigate
intermittent resources and inadvertent energy at
the interconnection.
Project Benefits and Highlights
• Project will be one of the fastest responding
storage systems in Southern California.
• The new (BESS) will help to regulate our
interconnection with LADWP to operate within
demand thresholds.
• It is scalable so that we can gain experience on
how to use the storage technology to determine
full scale energy storage projects in the future.
Project Benefits and Highlights
(Cont.)
• It will help mitigate intermittency of the
renewable sources such as solar generation.
• Capable of providing emergency power to start
GWP’s Power Plant generators in case of a
major system outage.
• It incorporates this new technology into GWP’s
renewable resource portfolio.
Project Schedule
• Ground Breaking: November 16, 2016
• Construction Start: November 17, 2016
• Projected Project Completion: By April, 2017.
• Small Scale – scalable
• Learn to integrate with system
• Understand programming to
charge/discharge system
• Repowering project allows for bigger
system
• 20 - 40 MW BESS
• Battery needs source to charge
