What is “Energy Storage”
• The Google says…
“Energy Storage is the capture of energy
produced at one time for use at a later time”
-Wikipedia

When You Hear “Energy Storage”
You Think of…

How About…
These technologies capture of energy produced at one time for use
at a later time – to drive, take hot showers, cool buildings, lift things.

Time to Implement! –
The “Community Storage Initiative”
More to come?....
![Page 8: Energy Storage: (Batteries)… AND EVERYTHING ELSE · Storage Vs. DR / Load Control • Some DR cuts load when energy use is high or supply is low. • Thermal or community storage](https://reader033.vdocuments.net/reader033/viewer/2022042307/5ed3ec85b38510386857385a/html5/thumbnails/8.jpg)
The “Community Storage Initiative”
• Other technologies throughout the community can store
energy and provide benefits to energy users and the grid
• As battery interests and need for renewables take off, more
opportunities will be available for consumers
• This can build on traditional DR programs and incentives,
including off-peak rates and avoiding demand charges.
• Take energy when price is low and not when it is high.

Supporting Community Storage Initiative
• We should not lose sight of storage options (or overlook
them) as batteries gain attention and capital
![Page 12: Energy Storage: (Batteries)… AND EVERYTHING ELSE · Storage Vs. DR / Load Control • Some DR cuts load when energy use is high or supply is low. • Thermal or community storage](https://reader033.vdocuments.net/reader033/viewer/2022042307/5ed3ec85b38510386857385a/html5/thumbnails/12.jpg)
Storage Vs. DR / Load Control
• Some DR cuts load when energy use is high or supply is low.
• Thermal or community storage can make use of energy when
it is available and stores it for later – can cut use or add it:
perfect for renewable integration.
• Grid Interactivity can take it even further, with storage proving
frequency response and acting like a peaker plant.

Thermal Storage
The Most Cost-Effective Storage
• Not flashy, but has been reliable for decades and is
cheapest solution available, and is HERE!!!!

Using Devides You Already Use to Teach
CA’s the “Duck to Fly”
“1 million electric water heaters means that up to 4,000MW of load could be
dispatched as needed, and that up to 10,000MWh per day could be shifted as
needed.” – Regulatory Assistance Project

What Can You Do?
1st – Go Electric!
• Electricity is increasingly the environmental choice

Growing Consensus for
Environmentally Beneficial Electrification
Lawrence Berkeley National Lab finds:
The key to meeting GHG goals is “widespread electrification of passenger vehicles, building heating, and industry heating.”
• United Nations, E3, Acadia Center, Stanford and Columbia Universities, California Pathways Project, DOE’s QER, Bill Nye the Science Guy and many more are all adding to the chorus.
• Consensus on benefits of renewed electrification - this
could result in more incentive to electrify

These things Make ELECTRICITY
• And create the variability that creates the need for storage…
• You need to choose end-uses that use electricity to benefit
from the evolving electric system.
• Variable generation may make your variable loads more
valuable over time as the market for storage increases.
