Market Pricing Integrated Proposal:

Consequences, Trade-Offs & Implementation

Market Operations Standing Committee of the IMO

background
Background
  • Three pricing issues
    • pre-dispatch vs. real-time prices
    • counter-intuitive prices in times of shortage
    • size, content and variability of uplift
  • Contributing factors not only give rise to pricing issues, but also:
    • reduce market efficiency
    • jeopardize reliability of IMO-controlled grid

Market Operations Standing Committee of the IMO

given that
Given That...
  • Maintaining status quo is not acceptable:
    • pricing signals and outcomes (incl scarcity pricing)
    • reduced market efficiency; reliability at risk
  • Supply is tight in Ontario for foreseeable future
  • Market structure schedules “just enough” resources to meet market demands
  • Significant increase in average HOEP would cause hardship to load customers

then……….

Market Operations Standing Committee of the IMO

proposed integrated approach
Proposed Integrated Approach
  • Objective:
    • Provide rational and understandable market prices, improve efficient operation of IMO-administered Markets and improve reliable operation of IMO-controlled Grid
  • Strategy:
    • Reduce frequency of need for control actions, then change manner in which control actions are utilized i.e. put control action sources of Operating Reserve “in the market”
    • Staging of initiatives

Market Operations Standing Committee of the IMO

summary of stages
Summary of Stages
  • Stage 1 (already underway):
    • 4-2 window; HADL; additional market information
  • Stage 2 (under development):
    • reduce failed transactions
    • spare generation on-line
  • Stage 3:
    • additional supply (R/S of domestic generation units)
  • Stage 4:
    • put control action OR into the market (price & qty)

Market Operations Standing Committee of the IMO

consequences and trade offs
Consequences and Trade-Offs

Initiative and Approach Address Pricing, Efficiency & Reliability Issues but…..

Initiatives, singly and together, have consequences that would mean trade-offs to achieve the stated objective

Question:

To what extent are these consequences and trade-offs acceptable in order to move the market forward from the status quo?

Market Operations Standing Committee of the IMO

spare generation on line
Spare Generation On-Line

Issues/Consequences/Trade-offs - Market Pricing

  • Potential for reduced price volatility; scarcity pricing
  • Downward pressure on market prices (impact of 12x ramp rate in market schedule)

Issues/Consequences/Trade-offs - Suppliers

  • Level playing field with neighbouring suppliers
  • Potential for reduced market value of flexible generation
  • Potential for reduced generator revenues through reduced prices
  • What costs are guaranteed? Is auditing necessary?

Market Operations Standing Committee of the IMO

control action or
Control Action OR

Issues/Consequences/Trade-offs - Suppliers

  • Potential for not scheduling market sources of Operating Reserve
  • Cap on Operating Reserve prices; scarcity pricing
  • Activation vs Scheduling

Issues/Consequences/Trade-offs - Loads

  • Potential for reduced reliability and quality of service i.e. potential for increased utilization of voltage reductions
  • Upward pressure on market prices; rational price signals and outcomes

Market Operations Standing Committee of the IMO

control action or1
Control Action OR
  • Objective is to reduce pricing issues
  • Proposal - to offer Control Action Resources into the market based on their value
  • Value difficult to determine directly - use participant issues to arrive at approximate value

Market Operations Standing Committee of the IMO

control action or2
Control Action OR
  • Value of Control Action Resources - participant issues
    • Maintain reliability and quality - limit exposure
    • Minimize competition for OR selection with dispatchable resources

[Lower Bound on resource price]

    • Impact on average HOEP should be consistent with the benefit of use of Control Action OR

[Upper Bound on resource price]

Market Operations Standing Committee of the IMO

control action or3
Control Action OR
  • Uncertainty in implementation
    • Control Action Resources are included in pre-dispatch and real-time
    • Impact of initiatives going forward is difficult to quantify
    • Balance of benefits is difficult to establish
  • Uncertainties are driving conservative impact assumptions - balance of benefits skewed depending on assumptions

Market Operations Standing Committee of the IMO

control action or4
Control Action OR
  • Implement Stage 4 in steps
    • Prudent approach recognizing uncertainty
    • Allow assumptions to be benchmarked
    • Allow participants to react to market changes

Market Operations Standing Committee of the IMO

control action or5
Control Action OR
  • Proposal
    • Implement 200 MW of 3 % V/R as soon as possible (covers 15 % of historical incidents), followed monthly by;
    • additional 200 MW of 3 % V/R (total 3 % covers 60 % of historical incidents)
    • 280 MW of 5 % V/R
    • Removal of 200 MW supplemental OR requirement
    • Allow pricing of 30 minute OR shortfall

Market Operations Standing Committee of the IMO

control action or6
Control Action OR
  • Trade-off’s are required -

Minimize competition for OR selection with dispatchable resources

- choose conservative prices to meet objectives

- choose prices which meet 95 % criteria in pre-dispatch

ie. 95 % of historical pre-dispatch OR MCP’s < OR price chosen

- Results in OR price of;

30 $ for 3 % Voltage Reduction resource

Market Operations Standing Committee of the IMO

control action or7
Control Action OR
  • Choosing price based on 95 % pre-dispatch criteria results in outcomes for objectives 1 and 3
    • - Maintain reliability and quality - limit exposure

- Load exposure expected to be less than that experienced in 2002

    • - Impact on average HOEP consistent with benefit of use

- Upper bound impact on average HOEP is expected to be approximately neutral

Market Operations Standing Committee of the IMO

control action or8
Control Action OR
  • Benefits of the stepped approach
    • Starts to address pricing signal concerns immediately (first 200 MW addresses ~ 15 % of historical incidents, second 200 MW ~ 60 %)
    • Starts to improve reliability based on better price signals
    • Allows the marketplace to gain experience with control action resources in the market
    • Allows for benefit of other initiatives to be observed and factored into future steps

MM 1.2 Facility Registration, Maintenance and De-Registration
  • Market participants are required to complete a registration form. Information to be provided:
    • Market Participant Name and ID;
    • Resource Name and ID;
    • Minimum Loading Point [MW];
    • Minimum Run-Time [hrs].
  • This information should be fairly static. Any modifications will be processed via the facility registration change-management process.

mm 4 2 submission of dispatch data in the real time markets
MM 4.2: Submission of Dispatch Data in the Real-Time Markets
  • The sequence of events is:
    • Market participant decides to start up its unit and run in hour H;
    • Market participant ensures that a valid offer for the unit is submitted at least 3 hours before the dispatch hour H;
    • Market participant is allowed to revise its offer without restriction until the start of H-3;

Market Operations Standing Committee of the IMO

mm 4 2 continued
MM 4.2: continued

The sequence of events is (cont’d):

  • After the publication of the H-3 pre-dispatch results and until the start of H-2, the market participant is not allowed to revise the portion of dispatch data reflective of the unit’s Minimum Loading Point;
  • Market participant may synchronize its unit anytime after the H-3 pre-dispatch run, but no later than the end of hour H;

Market Operations Standing Committee of the IMO

mm 4 2 continued1
MM 4.2: continued

The sequence of events is (cont’d):

  • Once the unit has reached its Minimum Loading Point, the IMO will constrain the unit to at least this minimum for the duration of its Minimum Run-Time;

Market Operations Standing Committee of the IMO

settlement principles
Settlement Principles
  • Guarantee recovery of start-up, minimum load ramping and minimum generation cost - Combined Guaranteed Costs.
  • The MP will be compensated if market revenues from Energy, Operating Reserve and CMSC payments, earned by the facility over the period between synchronization and the end of the MP specified MinimumRuntime is less than the Combined Guaranteed Costs submitted by the MP.
  • Guarantee payments will be paid out to eligible Market Participants monthly, and will be calculated on a “per start” resolution.
  • Costs for guarantee payments will be recovered from other Market Participants as a monthly uplift charge on basis of AQEW.

Market Operations Standing Committee of the IMO

mm 5 5 physical markets settlement statements
