1a) STORAGE WILL BE KEY TO RENEWABLES
AND ENERGY SECURITY1
 
A renewables-based system is more secure (local or
regional sources) and more resilient (more distributed)
 
Storage would provide grid stability in a 100%
renewably powered electrical system
 
For example, when Europe is at 100% renewables,
20-80 GW of power storage gives enough power for
the anticipated 50-130 GW grid renewables power
 
Needed storage for energy depends on amount of
biomass and level of European grid integration: At
10% (490 TWh) backup dispatchable renewables, ca. 2
days (27 TWh) short-term energy storage needed
Results for power of balancing technologies divided by the total
production power installed at different shares of European renewable
power

1b) STORAGE MAKES THE GRID MORE
RELIABLE AND RESILIENT
 
Storage enables reliable and stable renewables transition
o  Renewables need instant load following due to rapid intermittency
o  Battery storage has millisecond activation, and can supply excellent grid reliability in all stability markets
o  &12<<8>;,.8/<=*+252=B*7-;.52*+252=B8/=1.0;2-2<7..-.-@2=127,;.*<270<1*;.8/G>,=>*=270;.7.@*+5.<
 
Whenever possible, storage should be allowed to compete in all power and electrical energy mar kets
o  Current market structure largely designed for outdated centralized thermal plants
o  Storage can compete in all of capacity, energy, and operating reserves markets, and at all applicable
timescales and planning scales, plus in-front-of-meter (utility-side) and behind-the-meter (customer-side)
 
When able to compete in all relevant mar kets, the public value of storage on the grid is maximized
o  For example, a T&D operator may need a storage asset for 100 peak hours in a year of 8,760 hours
o  If the application is limited only to T&D, then for 8,660 hours/year the asset is underutilized
o  Instead, the T/DSO could rent it to merchant operators for wholesale market services provision
o  &12<27,;.*<.<89.;*=287*5.//.,=2?.7.<<*7-,8<=./F,2.7,B
o  In turn, the customer pays lower rates

2a) STORAGE ENABLES NETWORK RELIABILITY
AND OPERATIONAL EFFICIENCY
 
Storage can improve reliability and stability for Networ k Owner s
o  %=8;*0.*7-8=1.;<8>;,.<8/G.A2+252=B269;8?.<,*9*,2=B./F,2.7,B*7-;.<252.7,.8/7.=@8;4<
o  Network operators can already do this with natural gas
o  However, on other forms of storage, network adoption may be hindered due to restrictions on ownership
 
To improve resiliency and networ k efFciency, storage would have to be correctly deFned and not restricted
o  Network to own a device even if it both offsets a T&D asset and participates in energy markets
o  Storage cannot be categorized simply "transmission/distribution" or "generation" because it is neither—this
inhibits its full utilization, as participation in the opposite markets would be disallowed
o  Instead, storage is can function as (1) transmission/distribution or (2) generation or (3) demand
o  Enables transition to active local networks that use low-carbon generation as best deal for consumers
 
Example mar ket mechanisms for networ k efFciency and innovation that already exist
o  Objective is to enable network companies to trial new technologies or ways of working, and to adopt

cheaper and more timely connections, or better manage issues on their networks

2b) STORAGE CAN EMPOWER CONSUMERS
IN AN INTEGRATED MARKET
 
Regional storage will stabilize regional low-Voltage grids via storage in Self-supply
 
Storage enables self-supply of load and frequency management
o  Gives lower-cost grid relief from local peak-load shifting, shift of charging times, and improved power quality
o  Mechanisms would include peak-time charging incentives, e.g. time-of-day pricing, smart-meters and enabling

Storage enables self-supply of renewables smoothing
o  Gives T&D cost-deferrals from smooth & stable RE output. Islanding & microgrids could help
o  Helpful enabling mechanisms would include removal of taxes, grid fees, conversion costs, and
apportionments, whether currently charged separately or together with electricity price
