Market Evolution in Ontario
Adam Butterfield
Senior Manager, Electricity Resource Development
April 10, 2018
CanWEA Spring Forum 2018
Calgary, Alberta
• About Ontario’s Independent Electricity System Operator (IESO)
• Wind energy in Ontario
• Overview of Market Renewal
• Non-emitting Resources Subcommittee
• Non-emitting Resource Request for Information
Agenda
2
3
Enable province-wide energy conservation Administer the wholesale electricity market Work closely with communities and stakeholders
Reliably operate Ontario’s province-wide system 24/7
Enable innovation
Plan for Ontario’s future energy needs
IESO: Who we are and what we do

The challenge for all System Operators is to find ways to operate the grid cost effectively as it becomes increasingly digitized, de-
centralized, de-carbonized…. and much less predictable
A Changing Sector
5
• Fundamental redesign of Ontario’s electricity markets
• Demands of a modern grid are rapidly evolving
• Reforms are required to continue to manage the grid reliably and cost effectively
Market Renewal Overview

Market Renewal
Scoping Market Renewal
7
An ENERGY work stream
A CAPACITY work stream
• Single Schedule Market
• Day Ahead Market
• Real Time Unit Commitment
• Incremental Capacity Auction
More frequent Intertie Scheduling and other Operability/Flexibility projects also being explored
Near-term market enhancements consistent with Market Renewal continue to be pursued
• Subcommittee of the Market Renewal Working Group
• To ensure characteristics of non-emitting resources are reflected in Market Renewal and the future market
• Will develop a report for Q3/4 2018 that explores:
1. Participation
2. Market Efficiencies
3. Commercial Mechanisms
Non-Emitting Resources Subcommittee
8
Non-Emitting Resource RFI
9
• Will expand the IESO’s understanding of:
– The technical characteristics of existing resources and potential projects
– The potential barriers to participation different resource types are or may be facing
• Conducted in two phases over the course of 2018:
– Phase 1 (submissions due May 4): Input on participation in the current and future electricity markets
– Phase 2 (to be issued later in 2018): Input on resource development and broader considerations
The RFI is not part of Market Renewal
– However, Phase 1 aligned to support the Non-Emitting Resource Sub-Committee (NERSC)
– Phase 2 will help inform the next steps that follow from the work of the NERSC
– Input will be used to support Market Renewal and other IESO initiatives

Detailed Design
Future Evolution
Address uncertainty
Create a more flexible marketplace
Clearly defined “unbundled” products and services
IESO Vision for the Future
12
• Participate in shaping the future market
• “Potential barriers” – more detailed input/feedback
• It’s not only about building new facilities – broaden service offerings from existing wind farms
Final Thoughts – How can you help?

IESO Resources – Keep in Touch

Single Schedule Market
16
Replace Ontario’s two schedule system with a single schedule market that better aligns price with dispatch
Reduced complexity
unlocks other design
changes
Improved price signals
increase efficiency of dispatch and investments
Together, these outcomes will reduce the production cost of electricity
Day-Ahead Market
17
• A new market allowing suppliers/consumers to lock into guaranteed prices for supply/consumption a day ahead of when it is required
What is changing?
• Efficient way of improving operational certainty for system operators as real-time approaches
• Improves financial certainty for dispatchable resources
• Establishes a hedge against price volatility in the real-time market caused by changes in supply and demand
What are the benefits?
Enhanced Real-Time Unit Commitment
18
Unit commitment processes provide financial incentives that ensure resources with long lead times to provide energy are available when they are needed
Ontario’s current real-time commitment process has a number of shortcomings (e.g., does not consider start-up costs, makes commitments based on a one-hour period)
The enhanced real-time unit commitment process will include start-up costs and a longer timeframe to make more efficient commitment decisions
19
Incremental
• Will secure resources to meet system adequacy needs that are not met by contract or rate regulation
• Contracted and regulated capacity will not be eligible to participate
Capacity
• Will procure a single uniform capacity product
• Other products and services will be incentivized via other revenue streams
Auction
• A stable long-term mechanism that will secure capacity in a technology agnostic manner from diverse resource types
• Fundamental change in risk allocation from contract paradigm
Incremental Capacity Auction
