H2@Scale: The Role of Storage and DER for California

Angelina Galiteva: Member CAISO Board of Governors, Founder Renewables 100 Policy Institute, November 2017 Electric industry in the midst of unprecedented change - Driven by fast-growing mix of interrelated issues

Federal Election Existing Impacts Gas Storage 50% goal Challenges

NEW Community 100% goal or Retail Choice Grid Modernization Regional Collaboration Consumer-owned Power Fossil Plant Transmission & Retirements Distribution Systems Interface

• Balance supply and demand…every 4 seconds • Operate markets for wholesale electricity and reserves • Manage new resource interconnections • Plan grid expansions

Page 3 One of nine Grid Operators in the U.S.

• 2/3 of the U.S. is supported by an ISO

• ISO is one of 38 balancing authorities in the western interconnection

Supporting Evolution of the Electricity Grid

Historical Grid  “Smart” Grid 7 The “State of the State” of Renewables

73,000 MW of installed capacity – 30,000 load +/- in spring and fall

20,000 MW of utility scale renewables – Solar peak 8,545 MW (Sept ‘16) – doubled in 2 years

Another 5,000 MW to meet 33%

12,000-16,000 MW to meet 50%

4,500 MW of consumer rooftop solar – 11,000 new/month; = 50-70 MW / mo.

Slide 8 Clean, plentiful renewables…what’s the problem? - Oversupply and Steep Ramps

Potential Over Supply

Curtailments 10,000 - 13,000 MW occurring now ramps commonplace

Slide 9 NOT the Duck: ISO gross load curve is changing

Dip is attributable to rooftop solar

Page 10 ISO working on a 50% duck curve

Much steeper ramps

Much deeper belly

Slide 11 Solar and wind attract 60% of new investment in power generating capacity

Investment, by technology, 2017-2040 Investment, by technology, 2017-2040 ($ trillion - 2016 real)

Wind $3.3 Fossil fuels 14% Solar $2.8

$10.2 trillion Nuclear $1.4

Hydro $1.1

Zero- carbon Gas $0.8 86%

Coal $0.7

Pumped Hydro: 4087 MW Electro-chemical: 146 MW Thermal: 28 MW Pumped Flywheel: 2 MW Hydro 96%

14 No Single Solution to Oversupply and Ramping - Need to Decarbonize, Decentralize, Regionalize

A comprehensive solutions set is needed

Energy storage — bulk, distribution-sited facilities, consumer owned

More customer demand response

Retrofit existing power plants — lower minimum operating level; gain flexibility

Enable economic dispatch of renewables – allow them to “bid-out” of the market

Decarbonize transportation fuels

Deepen regional coordination — big impact; make use of installed assets EIM

Consumer participation — align time-of-use rates w/ system conditions Integration Issues

• Variable resources / not highly predictable

• Generation Profile vs CA

• Not Dispatchable

• Seasonal Issues (Over/Under generation)

• No Contribution to System Inertia, Frequency Control, Other Ancillary Services 16 ISO Programs Enable Participation

Energy Storage & Distributed Energy Resources (ESDER) – Enable transmission-connected storage and distribution- connected resources to participate in ISO market (2016)

Distributed Energy Resource Provider (DERP) – Pathway for distributed resources to bundle & participate

Energy Commission research: • 3 CAES projects • 6 flow batteries • 2 zinc-air batteries • 8 lithium-Ion batteries • 4 electric vehicle solutions • 2 sodium sulfur batteries • 2 flywheels • sodium nickel battery
