Strategen Consulting (www.strategen.com) provides insight to global corporations, utilities and public sector leaders,helping them to develop impactful and sustainable clean energy strategies
The California Energy Storage Alliance (CESA) (www.storagealliance.org) is a 501c(6) membership-based advocacygroup committed to advancing the role of energy storage in the electric power sector through policy, education,outreach, and research.
The Global Energy Storage Alliance (GESA)(www.globalesa.org) is a 501(c)3 non-profit organization founded in 2014whose mission is to advance education, collaboration, knowledge and proven frameworks about the benefits of energystorage and how it can be used to achieve a more efficient, cleaner, reliable, affordable and secure electric powersystem globally.
Energy Storage North America (ESNA) (www.esnaexpo.com) is the largest gathering of policy, technology and marketleaders in grid-connected energy storage. Join 2,000+ market leaders from over 26 countries at ESNA 2018: November6-8, 2018 in Pasadena California.
Focus of today: How to build flexibility into market design
Future Energy Grid: Clean, Renewable, Highly Flexible
The First and Second Long-Term Auction will
contribute to Mexico’s clean energy generation by
1.9% and 3% starting in 2018 and 2019,
respectively.

Renewables have surpassed coal last
year to become the largest source of
installed power capacity in the world.
With the Third Long-Term
Auction it will be possible to
achieve the established goal
for 2024
Mexican law establishes clean power generation targets

California’s 2017 ‘duck belly’ is ahead of schedule and frequently reached below
estimated 2020 levels during YTD 2017

Energy storage is ideally suited for primary frequency response (PFR)
13
• Efficient provider: ≈ 100% of any MW of storage capacity can provide PFR
• Autonomous, instantaneous response & contribution
• Most storage has sufficient energy, e.g. ≥ 15 min., for PFR service
• Storage can be programmed for any desired PFR responses
• Fully configurable: rate of response, time-delay, deadband
• Bi-directional if required (under and over freq. support)

“In storage, I don't see other forums like ESNA. This is the only one I have identified, and I think by
the presence of all of these important stakeholders and authorities, it is the leader in this regard.”
