1 More Power. Less Plant. Grid Scale Storage: Building The World s Biggest Batteries Large Scale Solar UK April 2015 Dr Marek Kubik

2 Three objectives 1. Share how the characteristics of energy storage contribute to a strong grid and aid in the incorporation of variable renewable generation. 2. Convince you that utility scale advanced energy storage is commercially available today. 3. To share some case studies from across our global portfolio of projects.

3 But first, a bit about AES... Mission: Improving lives through safe, reliable and sustainable energy solutions. Diversity Across Markets, Fuels & Technology Dependable Provider to Utilities and Power Systems Income Sources (2014 adjusted PTC) By Fuel Type 18 countries 35,000 MW in operation 8 utility companies 10 million customers $39 billion assets $17 billion revenues 18,500 global workforce World leader in battery-based energy storage 3

5 It isn t always sunny or windy when you need it to be The classic way people envisage storage and renewables together Avoid curtailment of zero fuel cost, zero carbon energy Improves peak fuel source diversity and lowers effective heat rate 5

6 The (Solar) Duck Graph 6

7 Curtailment and ramping challenges Island systems with high renewables potential and limited interconnection particularly challenging. System balancing and constraint payments in the Irish Single Electricity Market (SEM) have grown in five of the last six consecutive years, from 100m in 2009 to 176m in In SEM, synchronous (i.e. wind and solar) penetration capped to 50% of demand to preserve system stability. 7

8 2. Convince you that utility scale advanced energy storage is commercially available today. Confidential and Private 2011 AES Energy Storage, All rights reserved. 8

9 Batteries on the grid Modular, scalable arrays with high availability from current technology Cells Vehicle Sub-Modules Trays Racks Grid Storage Arrays 40 MW Resource - 800,000 Cells 9

10 Advanced Storage Provides Twice the Resource Fast, accurate storage reduces cost and improves system security 10

11 Battery Energy Storage Systems (BESS) Benefits Incredibly fast, precise and controllable response Zero minimum generation Rapid deployment (less than a year) Not geographically constrained Modular, scalable and portable Addresses the energy policy trilemma High round trip efficiency (90%) Proven, reliable and always on (giving 24/7 service) 11

12 More than 200MW of energy storage resource A fleet of cost competitive, reliable storage resources Customers: 40 MW Cochrane 2015 Online Date 24 MW Los Andes MW Angamos MW Warrior Run 2015 Online Date AES IPL World s first grid Lithium-ion battery Feb MW Kilroot 2015 Online Date 64 MW Laurel Mtn MW Tait Sep 2013 Western Europe 2015 Online Date 12

13 Southern California Edison (SCE) selects more than 250MW of energy storage for local reliability 13

15 Adding System Reliability with Wind Serving PJM Interconnection world s largest power market Frequency regulation Renewable ramp control 100,000MW power system 98 MW Laurel Mountain Wind Farm with 64 MW Storage Resource West Virginia, USA Impact: Top performance scores Competitive bid, wins every hour vs. traditional Reduces regulation procured by ~1.7x Storage saved PJM $20m and 62,000tCO 2 in

16 Protecting the Grid from Outages and Events Supporting the North of Chile since 2009 Edison Award MW Angamos BESS Spinning reserves 3,000MW isolated grid Impact: Avoided load shedding Better use of low cost constrained generation Reduced system cost Improved reliability 16 16

17 Europe s Biggest Battery Planned 100 MW (200MW resource) Project at AES Kilroot 200MW Kilroot BESS System savings of 11m/yr and 123ktCO 2 identified Hailed as game changing green technology by BIS Energy Catalyst Market Innovation funding First 10MW (20MW resource) being deployed in 2015 to inform design of new system services and pave way for 100MW in MW Interconnection (rendered) 200 MW of flexibility (discharge + charge) 17 17

18 Conclusion Shared how the characteristics of energy storage contribute to a strong grid and aid in the incorporation of variable renewable generation. Shown you that utility scale advanced energy storage is commercially available today. Case studies from across our global portfolio show storage versatility and solutions built around user need.
