  • Balanced book
  • Low risk

A Market Stimulus
  • June 22-26, 1998 – a week that changed everything
  • Prior to June, 1998 the highest price for electric energy was typically $100/MWh

Power Markets 5 Years Ago
  • Over 375 traders
  • High volume/low margin business
  • Unbalanced books
  • Higher risk
  • Natural gas generation takes off
  • Risk management functions
  • Reserve margins?
  • Coordinated planning?

Market Meltdown
  • The California experience
  • Insufficient transmission
  • Insufficient generation
  • Market manipulation
  • Seriously making money
  • Impact on western markets
  • Price caps
11
The Underlying Economics
12
Market Mechanisms
  • Bilateral transactions
  • Energy markets
    • Day ahead market
    • Real time market
    • Locational marginal price (LMP)
    • Financial transmission rights
    • Capacity markets
    • Ancillary services markets
13
Power Marketing Today
  • Nine of the top ten players in the trading market for the third quarter of last year have now either totally withdrawn or pulled back substantially from the power trading market. (Power Markets Week, April 14, 2003, p. 26)
  • Back to basics for vertically integrated utilities
  • Hedge funds and financial institutions enter
14
Power Marketing Today
  • Increased counterparty risk
  • Increased transmission constraints
  • Less liquidity in the bilateral forward power markets
  • Increasing and volatile cash demands
  • S&P said that it considers purchased power agreements to be fixed-debt obligations
15
Power Marketing Today
  • Incentives to hold reserves have changed
    • Capacity markets
    • Price volatility in energy markets
    • Reserve requirements
  • Did large customers get what they wanted when they started this whole thing?
16
Purpose of RTO Energy Markets
  • Provides a market solution for transmission congestion
  • Provides a mechanism to deal with energy imbalance
  • Provides a commercial market
  • What is the future of bilateral trades?
  • Role of power marketers?
17
Congestion Management
  • Historically, transmission congestion was managed using TLRs
  • MISO testimony indicated that based on 2003 data, underutilization of transmission capacity during level 3 and higher TLR events averaged:
    • 16.4% in MAPP footprint
    • 10.9% in WUMS sub-region
    • 7.7% in remainder of MISO
18
Congestion Management
  • TLRs are an inefficient way to manage transmission congestion
  • Energy Markets manage congestion by redispatching generation based on energy prices at various points in the system (rather than physical curtailment through TLRs)
  • LMP-based market provides a way to compensate generators for redispatch
19
Structure of the Midwest Market
  • Real time LMP hourly market that allows self-scheduling
  • Day ahead LMP hourly market that allows self-scheduling
  • Financial Transmission Rights that hedge against day-ahead congestion
  • Capacity assessment and generation commitment for supply adequacy
20
Locational Marginal Pricing
  • An energy price that is calculated at each commercial node based on marginal generation bids for a time period, using a security constrained economic dispatch
  • LMP is a marginal price NOT an average price
  • All energy at a commercial node is priced at the LMP
  • Congestion between two nodes are valued at the differences between the nodal LMP’s
21
Example LMP Profile
22
Financial Transmission Rights
  • An FTR is the right to collect the difference in LMP between two commercial nodes
    • Options
    • Obligations
  • Settlement of FTR’s is separate from settlement of energy or congestion charges
  • No schedule is required to collect FTR revenue
  • FTR’s can be traded bilaterally or in an auction
23
Options
  • An option is a type of FTR in which the owner does not pay congestion costs when the Target Allocation is negative, but receives congestion costs when the Target Allocation is positive
  • The Target Allocation is equal to the LMP at the Point of Delivery minus the LMP at the Point of Receipt
24
Obligations
  • Obligations are a type of FTR for which the owner may either pay or receive congestion costs
    • When the Target Allocation is negative, the owner must pay congestion costs
    • When the Target Allocation is positive, the owner receives congestion costs
