3 Survey: What regulatory changes would have the greatest impact on making the business case for ES implementation? Survey ESRC under 50 respondents stakeholders 1. End-users / utilities 2. Integrators 3. Test / research facilities 4. Vendors Objectives: ES market & testing market Conduct analysis sector and define key SWOT elements Engage with stakeholders to better understand user needs in the sector 3

4 Documentation Supporting System Safety Financial Stability Insufficient History to Demonstrate Qualifications and Experience Insufficient Understanding of Long Term Behavior/Degradation of System and Maintenance Performance Reliability Ability to perform remote alarm monitoring capabilities and service dispatch capability Data access/availability More survey insights 80% 70% 60% 50% 40% 30% 20% 10% 0% ES customers: What are your perceived challenges in dealing with vendors? a gap between idea of stacked services and compensation: Most (54%) respondents can receive compensation for 1-2 services 23% receive compensation for no services / 23% for 3-4 services 4

8 The ESRC: unlock and de-risk Conclusions for the ESRC The need is to unlock stacked benefits Test use cases Process big data and provide all possible data analytics De-risk for vendor, integrator, user and the sector Day (Reference) Bring ESS to max SOC Day 1 100% Rated Day 2 100% Rated Day 3 100% Rated Day 4 75% Rated Day 5 50% Rated Day 6 25% Rated Data processing: register mapping to test protocols Available Energy Capacity Time normalized by Description Pretest Calculations (Hours) ESS rated power (kw) (Notes) ESS Rated Charge (kw) 100 Bring the ESS to 100% SOC ESS Rated Capacity (kwh) Stop the charge/discharge cycle when the target SOC is reached Duty Cycle Time Wait 8 hours after the last charge Discharge at 100% manufacturer recommended rated discharge ESS Rated Discharge (kw) 100 power rate until minimum SOC or BOC ESS Rated Capacity (kwh) Terminate discharge cycle at minimum SOC or BOC Duty Cycle Time Allow to site idle for 10 minutes Charge at 100% manufacturer recommended rated discharge power 10 Minute Idle Period rate until maximum SOC or TOC Per Day Idle Period Stop at maximum SOC or TOC Allow system to stabilize for minimum of 8 hours Top-off Charge Time (hr) Discharge at 100% manufacturer recommended rated discharge Current SOC (%) power rate until minimum SOC or BOC Target SOC (%) Terminate discharge cycle at minimum SOC or BOC Allow to site idle for 10 minutes Charge at 100% manufacturer recommended rated discharge power rate until maximum SOC or TOC Stop at maximum SOC or TOC Allow system to stabilize for minimum of 8 hours Discharge at 100% manufacturer recommended rated discharge power rate until minimum SOC or BOC Terminate discharge cycle at minimum SOC or BOC Allow to site idle for 10 minutes Charge at 100% manufacturer recommended rated discharge power rate until maximum SOC or TOC Stop at maximum SOC or TOC Allow system to stabilize for minimum of 8 hours Discharge at 75% manufacturer recommended rated discharge power rate until minimum SOC or BOC Terminate discharge cycle at minimum SOC or BOC Allow to site idle for 10 minutes Charge at 75% manufacturer recommended rated discharge power rate until maximum SOC or TOC Stop at maximum SOC or TOC Allow system to stabilize for minimum of 8 hours Discharge at 50% manufacturer recommended rated discharge power rate until minimum SOC or BOC Terminate discharge cycle at minimum SOC or BOC Allow to site idle for 10 minutes Charge at 50% manufacturer recommended rated discharge power rate until maximum SOC or TOC Stop at maximum SOC or TOC Allow system to stabilize for minimum of 8 hours Discharge at 25% manufacturer recommended rated discharge power rate until minimum SOC or BOC Terminate discharge cycle at minimum SOC or BOC Allow to site idle for 10 minutes Charge at 25% manufacturer recommended rated discharge power rate until maximum SOC or TOC Stop at maximum SOC or TOC Allow system to stabilize for minimum of 8 hours normalized by ESS rated power (kw) 8

9 Role ESRC in triangle between technologies, readiness level and stacked benefits Create multiple testing capabilities to qualify both Li-ion and new technologies Deploy software opportunities Support the stacked benefits niche for each of them 9
