The Western Energy Imbalance Market • Automated dispatch minimizes cost, facilitates renewables, resolves imbalance, avoids congestion • Situational awareness enhances reliability • Harmonizes with bilateral trading and regional reserve sharing groups • Preserves Balancing Authority Area (BAA) autonomy, including compliance, balancing and reserve obligations • Benefits from EIM operation total $801 million through Q3 2019 https://www.westerneim.com/pages/default.aspx Page 3 ISO PUBLIC - @ 2019 CAISO
Market efficiencies depend on robust transmission Page 4 ISO PUBLIC - @ 2019 CAISO
Western EIM governance structure • 5 independent, non-stakeholder members • Delegated authority over EIM-related market rules EIM Governing Body • Selected by stakeholder nominating committee, confirmed (GB) by EIM Governing Body • Provides western entities a decision-making voice • Advises the EIM Governing Body and ISO Board of EIM Body of State Governors on matters of interest • Currently eight state officials from EIM states Regulators (BOSR) • Provides a state regulatory perspective • Public vehicle for discussion of EIM-related issues, including impacts to neighboring balancing authority areas Regional Issues • Organized by ten self-selected sector liaisons Forum (RIF) • May produce opinions for EIM governing body or ISO Board of Governors Page 5 ISO PUBLIC - @ 2019 CAISO
Stakeholder input is essential to ISO planning, processes and enhancements New initiatives and policy updates implementation http://www.caiso.com/informed/Pages/StakeholderProcesses/Default.aspx Broad market EIM enhancements enhancements Process and tool enhancement implementation Updates are made based greatly upon the input of our customers Page 6 ISO PUBLIC - @ 2019 CAISO
EIM provides a low-cost, low-risk option that balances load and resources automatically and economically in the real-time market ISO BAA footprint • ISO optimizes energy transfer and Day-ahead & Real-time Market generation output between all EIM participants in multiple increments • Single optimization across EIM footprint improves quality and helps overall system reliability • Currently applies to real-time market only, but a new initiative proposed to extend EIM to day-ahead EIM footprint Real-time Market Only Page 7 ISO PUBLIC - @ 2019 CAISO
Extended Day-Ahead Market (EDAM) • Extend EIM to include DA market Follow this initiative under • the Stay Informed tab of Same foundational concepts as EIM: the ISO website at: – BAA autonomy http://www.caiso.com/infor – Voluntary entry med/Pages/StakeholderPr – No exit fees ocesses/ExtendedDay- AheadMarket.aspx • EIM will be maintained as a stand-alone service • Stakeholder process initiated in October 2019, running through early 2021 • Major topics Transmission availability and pricing Resource sufficiency Greenhouse gas Governance Page 8 ISO PUBLIC - @ 2019 CAISO

Participating vs. Non-Participating EIM RESOURCES ISO PUBLIC - @ 2019 CAISO
Who is participating and what does that mean? Participating Resource Non-Participating Resource A resource that submits bids that A resource that intends to operate in allow the EIM market to dispatch or the BA but does not allow the EIM not dispatch the resource in real-time market to dispatch or not dispatch the resource in real-time Bidding makes Submits base schedules resources available to to ensure BA balancing resolve energy calculations are accurate imbalances Page 14 ISO PUBLIC - @ 2019 CAISO
The ISO settles with scheduling coordinators who allocate payments and charges to their customers Non-participating Load (demand) Entity Scheduling Coordinator Non-participating Resources (non-bidding) Participating Participating Resource Resources Scheduling (bidding) Coordinator EIM Entities allocate the cost based upon their Open Access Transmission Tariff (OATT) Page 15 ISO PUBLIC - @ 2019 CAISO
How are base schedules settled? Participating Resource Non-Participating Resource • • The Market Operator will The EIM Entity Scheduling settle the deviations from Coordinator will be base schedules for responsible for the participating resources at settlement of deviations from the locational marginal price base schedules for these at the corresponding resources. locations. Charge codes allow for greater granularity in the breakdown of charges and payments for greater transparency.

Real-Time Market EIM MARKET TIMING ISO PUBLIC - @ 2019 CAISO
The ISO Markets – Where does EIM fit? Day-ahead market (DAM) T - 8 days 10:00 13:00 Bids, schedules, DAM process Publish Clear the resource begins market results market plans submitted Triggers real-time market Now let’s talk about real-time Real-time market (RTM) markets Beginning at midpoint of T-1 after 13:00 T-75min each 5min period Bids/Base RTM Clear the Receive Post Market schedules processes market dispatches Processes submitted begin Page 18 ISO PUBLIC - @ 2019 CAISO
Real-time markets do the following: Send dispatch signals to Procure “balancing” resources to move up or energy to meet the down to meet current forecasted real-time grid system conditions energy demand Protect operating Maintain the security of reserves that the market the system is aware of (no normal or post- contingency overload) Page 19 ISO PUBLIC - @ 2019 CAISO
The ISO market looks at resource future targets The market is always looking down the road Advisory solutions are best estimates of the future, but… …they can and do The real-time market allows for change operators to look ahead at resource usage and commitments Page 20 ISO PUBLIC - @ 2019 CAISO
Real-time Outputs: Resource Instructions 75 minutes before each • Intertie transactions that are hourly: trade hour Bids and hourly base • Submitted by EIM entity schedules submitted • Critical to be accurate used as baseline • For each fifteen minute interval we are: • Starting-up or shutting down resources 15 Minute Market • Transitioning multi-stage generators • STUC has longer time horizon • For each five minute interval we are: 5 Minute Market • Issuing real-time dispatch instructions • No start-ups/shut downs/transitions Page 21 ISO PUBLIC - @ 2019 CAISO
Hourly process for real-time market leading up to operating hour (EIM components) (T- = start of the hour) T-75: Base schedules and energy bids due (Resources) T-55: Updated base schedules are submitted if necessary (Resources) T-40: Updated base schedules are submitted if necessary (Entity SC) 01:45 EIM Market 02:05 T-20: E-tagging deadline participants (Entity SC) 02:20 02:40 T RTPD7 RTPD6 RTPD5 RTPD4 3:00 4:00 02:37.5 02:23 Hour ending 02:08 15-minute scheduled awards published Start of 15 minute market 01:48 Results of all base tests published Market operator Results of all base tests published Page 22 ISO PUBLIC - @ 2019 CAISO
