3 Phase I Energy Storage program lessons learned HISTORY AND BACKGROUND 3

4 Ontario Long Term Energy Plan Phase I Energy Storage Program History Minister s Directive authorizing phase I and II storage programs Phase I RFP: 12 projects by 5 different proponents: 9 RSVC facilities and 3 regulation service facilities Various changes of location and control by many projects Phase I storage facilities reach the Market Commissioning stage and begin entering the electricity market (7 out of 11 as of May, 2018) 4

6 IESO contracted energy storage portfolio (110.5 MW) as of April, 2018 Eleven Phase I Energy Storage facilities now entering the market or in final stages of commissioning as of April,

7 Phase I Energy Storage program lessons learned PRE-COMMISSIONING: CHALLENGES EXPERIENCED 7

8 Sources of delay prior to the final registration and commissioning stages Commercial: Delays in finalizing legal agreements between the host LDC and the project proponent and in other cases, between the project proponent and their technology vendors or financiers. One project affected by a component supplier exiting the market Co-operation of the host LDC is a key success factor and it varies Regulatory environment: In some cases, limitation in technical resources within LDCs to conduct Connection Impact Assessments Environmental assessment of MOECC noise impact has resulted in additional project work to enclose works in soundproofed buildings Absence of formalized framework to integrate storage projects at the distribution level Delays to permitting affects multiple construction dependencies if it is delayed. Applicability of distribution charges is emerging as a significant issue: 3 differing views of transmission-connected resources in Ontario: Wholesale market rules, OEB distribution rules and Transmission Tariff rules Inadequate assessment of materiality of these charges by some phase I participants 8

9 Typical timeline for Phase 1 facilities 3.5 years from contract signing to Registration Authorization into the electricity market A majority of the time spent site selection, local connection approvals and other activities before the IESO registration process begins Approximately 1year for IESO registration/commissioning 9

11 Commercial Risks Establishing, revising, and maintaining commercial s has extended project timelines for several phase I projects.

12 Permitting Risks For some phase I projects, administrative delays and changing requirements have all pushed out timelines for the permitting process, which have multiple downstream dependencies for development timelines.

13 Connection risks For some phase I projects, the with the Host LDC has been a crucial factor affecting project timelines. In some cases estimated connection timelines of months have been cited by some LDCs. Competing, formalized priorities for FIT/microFIT connections have sometimes been offered as a reason.

14 Distribution charges Ministry of Energy Directive In Ontario, there are different views as to the boundary of the transmission system based upon: Voltage and connection topology (IESO Market Rules, Electricity Act) Ownership of connecting assets (OEB codes, and Transmission Tariff orders) In some cases, the applicability of distribution charges to transmission connected phase I projects was an extensive, ongoing OEB topic of discussion between ASPs and the host LDC.

15 The ongoing role of storage While the OEB has created an Electricity Storage Licence in Ontario, the characteristics of energy storage facilities and their treatment have yet to permeate into the more detailed levels of codes, market rules and priority setting at all levels of the Ontario electricity system. For new entrants, basic information gathering on the treatment of their facilities is a complex, and sometimes error-prone, undertaking that can add to project timelines.

16 Registration Risk Phase I Energy Storage participants AND their facilities must be registered in the IESO-administered markets a complex 6-8 month process Ministry of Energy Directive OEB Licencing IESO Min of Env. and Climate change Phase I agreement + market participant Noise reduction regulations Ancillary Service Provider (ASP) Ownership Leases, connection agreements and customer Host LDC Metering Service Provider Financier(s) Various debt/equity arrangements ASP Project holding entity Services Permits Local municipality Critical service agreements Developer(s) Other component manufacturers Systems Integrator(s) Purchase agreements Storage technology manufacturer 16

17 Phase I Energy Storage program lessons learned PROJECT REGISTRATION AND COMMISSIONING: CHALLENGES EXPERIENCED 17

18 General Challenges: Project Registration and Commissioning A highly complex process even for experienced market participants A lengthy process particularly for facilities with a short development cycle No specific market rules expressly set out the application of registration and commissioning requirements for energy storage facilities Multiple market manuals and related documents govern the process. Some requirements clearly only apply to generation facilities but no official guidance from the IESO market rules as to which ones. 18

20 Interim Operating Guide for RSVC facilities Applies to RSVC facilities only. The 2 Regulation facilities will resemble today s operations with the ATR fleet 20

21 Phase I Energy Storage program lessons learned LESSONS STILL TO BE LEARNED 21

22 Ontario s first dispatchable storage facilities are just beginning operations Looming questions: Can market participants adequately manage state of charge on their own? Is this the most efficient solution? Is the mandatory window for bid/offer changes too restrictive? Can storage facilities feasibly offer reliable operating reserve without state of charge monitoring in the DSO algorithm? Will conflicting dispatch between generator and load segments become a serious problem? 22
