the Commission

What changed?
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
3
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
4
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

What did we do before we went
back to the drawing board?
ENRON creates ether money;
wall street believes!

12
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
14
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
similar

designs
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
24
λ λ λ λ ...
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.”
