Technology has eliminated some market
failures
Generator size small compared to market
vertical integration not required for
communication

Growing pains
Markets have become larger than the
traditional political/regulatory boundaries
Recognize the efficiency benefits
Problems with sovereignty issues
Growing pains abound (U.S., Europe, Asia,
Australia, South America)
State v federal issues
East v west issues
Change takes time

History of merchant generation
and transmission
merchant generation is the U.S.
Pre-1978: almost none
PURPA: mandatory purchase
Opposition: threaten reliability
Wrong
Merchant transmission
Pre-2000: none
Crosslink (AU)
Opposition: threaten reliability
Wrong

cultural issues
2000 year debate What is the “just” price?
Is electricity a public good?
Enron/California backlash
Should the government hedge for citizens?
How important is administrative simplicity?
Competition
does not promise lower prices
Does produce lower prices than cost-based
regulation
5
Electricity markets
 Electricity markets have become highly interconnected.
 The policy question is how should the markets be organized?
 Externalities abound including
 lack of demand response (the central problem), reliability rules
 the laws of physics, business stealing, pollution
 free riding, market power and blackouts
 The vertically integrated utility (franchised monopoly)
 internalizes externalities
 creates efficient incentive problems and
 usually introduces rate regulation.
 a relatively unregulated market is politically unacceptable
 an exchange with rules and regulations that prevent
market power and promote efficiency
6
Value of competition
cost-based regulation
At best weak efficiency incentives
Weak innovation incentives
Naïve market power mitigation
Price = cost
Return on equity and imprudence?
Competition (market-based) regulation
strong efficiency incentives
strong innovation incentives (may take time)
7
market power mitigation (bidding rules)
information technology upsets the
vertically integrated utility paradigm
Computer technology improvement since
1970
Hardware: 109
Software: 106
Telecom:
fiber optics
Wireless
Internet
Expands the breath and depth of
competition possibilities
8
electronic
trading
 FERC requires
 1988 electronic access to pipeline information.
 1992 pipelines to conduct capacity auctions on EBBs.
 1994 electric utilities to transact business on EBBs
 1995 EBay: online auction site founded
 1997 Continental Power Exchange the predecessor to ICE
 1999 Enron Online
 bought and sold $880bn just two years.
 2002 sold to UBS and dies
 Floor/desk v. screen/computer
 NASDAQ: screen based
 NYMEX: dual system
 NYSE: 2006 starts dual system

There is no perfect
market design
there is no efficient market design that
satisfies
Individual rationality (value maximization),
incentive compatibility (efficient outcomes), and
Revenue adequacy (no outside money)
There is no perfect market design (costbased or market–based)
All markets are regulated
The policy question is how to design a ‘just’
market
13
A decade of expensive
failed market designs
Zonal markets (Cal, PJM, NE, UK)
Contract path
Sequential markets for energy and anc services
One settlement systems
Infeasible markets (Cal PX and UK)
Ignore non-convexities (start-up and no-load)
Ignore market power
As-bid/first-price pricing
all ended in administrative intervention
"Everything should be made as simple
as possible ... but not simpler." Einstein

Pre-day-ahead markets
for transmission rights: CRT/TCC/TRCs/FGRs
for generation capacity/reserves (ICAP)
market power mitigation via options contracts
day-ahead market for reliability(valium substitute)
simultaneous nodal market-clearing auctions for energy,
ancillary services and congestion
allow multi-part bidding
higher of market or bid cost recovery
allow self scheduling
allow price limit bids on ancillary and congestion
Real-time balancing myopic market
15
markets are nodal-based LMP with fish protection

 US: PJM, NY, NE, MISO, CA, SPP, ERCOT
 Asia/Pacific: New Zealand, western China, eastern
Australia, Philippines, ...
 Europe: Ireland
 Russia
 South America: Chile, Argentina, Columbia, Brazil, …
16
What’s next?
Complete the market design
Choice: don’t eliminate choice because
market participants don’t want it!!!!
More active demand side
Price all scarce resources
Mitigate market power
17
End-use markets
 Lacking demand response
 capacity markets
 build rate base generation and transmission
 energy-only market may not clear
 with demand response
 capacity markets become hedging markets
 energy-only market clears
First: Generation in drag
 Simple policy
 all replacement meters are interval
 Large customers put on real time prices
 Intelligent remote circuit breakers
 Offer hedges against real-time market
18
Rethinking reliability
Unbundling and Paying for reliability
 Old way: Voluntary “gentlemen’s agreements”
 Little or no liability; No Demand-side role
 “absolute” limits
 Primary cause of cascading blackouts: Vegetation and
Operator error
 Many models do not differentiate between
 Simple controlled curtailment
 Cascading uncontrolled blackout
 Some simplifications can cause anomalous results
 One event criteria
 Amount curtailed criteria
 Improving reliability
 Constraints are soft not hard: use pricing
 Some liability creates good incentives
 Demand curve for reserves
19
 reliability markets: pay for generation and transmission reserves
electricity market design
electricity market models and regulation have
generally been circumscribed by hardware and
software capabilities.
Modeling simplifications include
energy only,
DC only,
oversimplified topologies (contract path)
large time steps.
Simplifications create ‘missing commodities’
including
reactive power,
reserves (real and reactive) and
other ancillary services.

Computational considerations
“perennial gale of creative destruction”
Schumpeter
 Pre-1996: patched pool software
 1996: LMP in NZ
 300 nodes
 transmission constraints are manual
 1990s: linear programs improved by 106
 103 in hardware
 103 in software
 2000s: mixed integer programs improved by 103
 Hardware: parallel processors and 64 bit FP
 Software: cplex
 2006: 30000 nodes
 10000+ transmission constraints
 1000 generators with n-part bids
 MIP introduced in DAM
21
Benefits of better modeling
 A good portion is traded or dispatched using sophisticated
mathematical software
 Minor gains in auction efficiency are measured in billions
 Benefit/cost for better modeling can be over 250
 Where is the innovation occurring?
ISOs
exchanges
 Vertically integrated utility
 Examples
 MIP
 CCCT modeling
 Topology estimators
 Reactive power modeling

a ideal complete market design
(a target rich environment)
 all scarce commodities are
 simultaneously priced and
 cleared over both space and time
 using a full Mixed Integer ACOPF
 all assets as active market participants
 Market power mitigation.
 The market design has
 combinatorial marginal cost bidding with budget constraints,
 Non-confiscatory settlements and
 simultaneously clearing of all products.
 If different models are used for different time horizons
for planning, compatibility is important
 No Lagrange multipliers left behind

Value of an ISO
Owns no electric assets
Promote competition
Integrates dispatch, competition and reliability
Revenue-neutral non-confiscatory auctions
Cutting edge of software development
Better information
Planning for competition
Sounds unusual but all markets that involve land use are
regulated and planned
Entry sites: good electric locations

“A new scientific truth does not triumph by
convincing its opponents and making them see
the light, but rather because its opponents
eventually die, and a new generation grows up
that is familiar with it.”
