  • General Concepts on Cross Border Electricity
    Markets
  • Regional Markets in the World
  • A phased approach to CIS Electricity Market
    Integration

4
Why Cross Border Electricity Markets?
  • A regional electricity market typically enables
  • To improve quality of service through mutual
    support during emergencies
  • Alternatively to reduce the level of reserves
    necessary to achieve some level of service
    quality
  • To reduce the cost to meet the load through
    energy trading
  • To allow developing regional scale projects,
    which cannot be justified at countries level
  • To optimize at regional level the use of primary
    resources
  • To increase the competitiveness of markets
    through increasing the number of participants

5
Fundamentals of Cross Border Markets
  • Several products can be cross-border traded
  • Bilaterally-traded energy, day-ahead-traded
    energy, support during emergencies, balancing
    services, regulation reserve, spinning reserve
  • Each product entails different implementation
    requirements and also different benefit
  • Golden rule The easiest to implement provide
    the most benefit (bilateral and day-ahead
    markets)
  • Market integration implies some level of
    regulatory harmonization
  • Higher level of integration requires higher
    harmonization of rules, structure and market key
    elements
  • International experience shows that a large share
    of benefit is achievable with no or limited level
    of harmonization
  • Basic criterion for Market Integration Benefits
    Costs

6
Core concepts of Cross Border Markets
  • Regional Electricity Market
  • Set of agents involved in the electricity
    industry of a multinational geographical context
    (e.g. the CIS)
  • The market also entails all the procedures and
    rules established for promoting and regulating
    trading between market participants of the
    incumbent countries.
  • Regional Transmission Network
  • Composed of those facilities of the overall
    transmission grid (set of transmission networks
    of all the involved countries) that are relevant
    to interstate electricity trading.
  • For each particular element (line, transformer,
    etc.), this feature could be determined by
    checking its participation in energy
    transactions.
  • In a fully integrated multinational electricity
    market, the Regional Transmission Network is to
    be centrally operated and planned.

Products in Cross Border Markets
  • Physical Bilateral contracts
  • Day ahead markets
  • Balancing market
  • Financial contracts
  • Ancillary services market
  • Long term reserves
  • UCTE, USA, NordPool, SAPP, Central America, South
    America
  • Participants of one market offer-bid in each
    other UCTE, USA
  • Market Coupling Nord Pool, Central America,
    France-Belgium-Netherlands
  • Between SO Colombia-Ecuador
  • NordPool (partial)
  • NordPool, several in UCTE, NYMEX
  • Only through bilateral contracts
  • No experiences of organized markets. Implemented
    through bilateral contracts (Reserve provider and
    TSO or between TSO).

9
Bilateral Contracts and Forward Markets
  • Bilateral (OTC)
  • Physical most common and simple alternative for
    cross border trading. Obligation of seller to
    inject and the buyer to withdraw the committed
    capacity.
  • Financial (requires a price reference and
    short-term markets in each country). Is a price
    risk hedging product.
  • The seller compensates the buyer when spot price
    (SP) is greater than contract price (CP), the
    amount (SP-CP)PX
  • The buyer compensates the seller when spot price
    is lower than contract price (CP), the amount
    (CP-SP)PX
  • Long term contracts are normally linked to some
    structural price differential.

10
Bilateral Contracts and Forward Markets
  • Futures/options financial markets
  • For price risk hedging, typically no physical
    delivery
  • Includes credit risk management
  • Standardized products, for instance base/peak
    energy
  • Futures standardized forward contract (e.g. 1MW
    monthly base contract)
  • Call option right (no obligation) to buy energy
    at a price (strike price). The holder of the
    option pays a option premium to the seller.
  • Horizons from days to years
  • Operates in overall competition with the
    bilateral market.

11
Short Term (Opportunity)trading
Always market prices are different. Opportunity
trading takes advantage of this issue.
Benefits from cross border trading are only
limited by congestion, losses, or because prices
equalize in both countries
12
Opportunity Trading
  • Takes advantage of the prices (or marginal costs)
    differentials between interconnected countries
  • The only condition to benefit is that prices
    differentials are greater than transactions costs
    (the only real cost are losses)
  • Typical forms of opportunity cross border
    trading
  • Transactions between SO (countries without
    markets)
  • Participants of a country present offers in
    short-term markets of neighboring countries
    (UCTE, USA)
  • Regional day-ahead (NordPool, Central America)

13
Concepts about Day-ahead markets
  • Common activities
  • Market participants allowed to participate
    (licensed) present daily offers bids
  • The MO processes the offer-bids and select the
    units that will supply the load, accept buying
    offers set the price.
  • Accepted bids-offers turns obligations for the
    participants
  • The SO introduces technical corrections to
    ensure system security
  • The MO settles the transactions.
  • Alternative designs obligations of participants
  • Gross pool mandatory, all the energy must be
    traded in the DA, contracts are financial (for
    price hedging)
  • Net Pool only are traded differences between
    physical contracts and actual generation-load

14
Day-ahead markets
  • Alternative designs spatial dimension
  • Single price offers-bids are accepted regardless
    of the location and physical possibility to
    deliver the energy. The SO corrects the
    dispatch to relief congestion. Additional costs
    are pass through to consumers through a tariff
    up-lift
  • Nodal pricing transmission constrains are taken
    into consideration during the clearing process.
    Nodal prices reflects the costs of consuming
    energy in each node taking into consideration
    transmission constrains and (in some cases)
    losses.
  • Zonal pricing single price zones (SPZ) are
    defined. Congestion is only considered between
    SPZ.

15
Cross-border Day-ahead markets
  • Alternatives for cross border Day Ahead markets
  • Participants of a country presents offers-bids in
    the Day Ahead of another (interconnected) country
    and vice versa. Offers-bids can be presented in
    the borders (i.e. regulatory seams are smoothed).
    Approach used in USA-UCTE
  • The regional market each county has (or not) an
    internal market, but market participants-SO-utilit
    ies are allowed to offer-bid in a regional DA
    with its own rules. It is necessary a regional
    MO, regional congestions management and access
    charges. Used in Central America.
  • The common market there is an unified Day-Ahead
    market. Offers-bids do not identify between
    internal-external transactions. Regional MO
    substitutes national MO. Used in NordPool.
  • Market coupling close to common market, but
    bids-offers are differentiated between internal
    and cross-border. Unified clearing of cross
    border offers-bids. Used among France-Netherlands-
    Belgium.

16
Balancing Markets Balance Management
  • Different definitions and concepts. Substantial
    variation in the terminology used and the manner
    in which balancing services are organized
    throughout Europe and USA.
  • ETSO Balance Management means the management
    processes and services associated with power
    system operation, which ensure quality and short
    term security of supply. In particular this
    presentation focuses on active power balancing
    and frequency control.
  • ETSO grouped services into 3 types
  • Frequency Control (automatically delivery)
  • Reserves and Energy Balancing (manually
    instructed delivery)
  • Other services (e.g. Reactive power, resolving
    congestion)

17
Schematic sequencing of reserves
Instructed (manual, AGC) action of particular
generating sets linked to a control loop in a
control area, to move the overall system
deviation of the control area toward zero
Automatic reaction of the primary controller of
generating sets to a frequency deviation
Balancing based on merit order or reserves (fast,
tertiary,..)
18
Difficulties for cross border balancing markets
  • Regulatory pricing (single double marginal or
    pay as bid gate closure times settlement
    periods)
  • Institutional SO would compete for using
    balancing resources, is necessary a regional SO,
    or at least a hierarchy
  • Technical amount of non manageable renewable
    energy load shedding AGC ramps reaction time
    ..
  • Economical allocation of transmission capacity
    to balancing activities, withdrawing it for
    energy trading
  • The present trend is to control cross border
    flows to fulfill day-ahead or intraday schedules

19
Market for Long Term Reserves
  • There are two alternatives to manage regional
    reserves
  • Through energy markets
  • Bilateral option contracts (right to be supplied
    at a price)
  • Day-ahead market (that optimizes on daily
    intervals the entire available capacity)
  • Balancing market (that optimizes on real time
    basis the entire available capacity)
  • Through organized reserves (capacity) markets
  • SO agree on regional reserve need
  • A reserves market is organized, where generators
    and loads offer capacity/curtail to fulfill
    reserve requirements
  • This market must consider cross-border
    transmission capacity
  • Theoretically possible, no international
    experience

Generator GB of B enters in a bilateral contract

?
GB
  • In market B, GB declares a bilateral contract,
    with delivery node in the A-B border. The
    contract is included in the day-ahead schedule by
    Bs MO-SO. GB pays access charges for the
    transaction according with internal regulation.
  • LA offers 100MW in the border node NA, at zero
    price. As MO-SO considers the importation as a
    generator in the border. LA pays difference of
    nodal prices between NA and its node. LA pays
    internal access charges (pankaking).

22
How to connect Day-Ahead markets with different
design?
A LMP
B SPA
A considers injection/withdrawals as
generators/loads in the border node, priced at
the import/export price B considers
exports/imports as internal load/generation
A each border node has an injection/withdrawal
and a price (the price of the energy
imported/exported) B the imports are considered
as internal generation and exports as internal
loads
A LMP
B SPA
23
Two key Issues for Cross Border Markets
  • Congestion management, which deals with
  • Allocation of (usually scarce) cross border
    transmission capacity
  • Parallel flows
  • Essential for cross border trading, because as
    soon as bilateral/DA trading becomes liquid,
    cross border capacity turns fully utilized
  • Identification and Settlement of Deviations
  • The set of daily cross border transactions among
    all the participants of the market origin flows
    in cross border links
  • Members of the market must agree how to measure
    deviations form scheduled flows
  • Deviations from schedules (that means from agreed
    transactions) must be measured and settled.

24
Congestion Management
  • Typically, cross border transmission capacity is
    low in relation to countries internal loads,
    therefore it becomes necessary rules for
    allocating this capacity to transactions.
  • Commercial vs physical flows

In this case physical and commercial flows
coincides
Commercial transaction originates physical
flows
25
Transmission Rights
  • Physical Transmission Rights (PTRs) the owner of
    a PTR for X MW is entitled to inject X MW in a
    (fixed) node i and to withdraw the same power
    in other node j. Have several types
  • Absolute.
  • Use-it-or-lose-it
  • Use-it-or-sell-it
  • Financial Transmission Rights (FTRs) the holder
    of a FTR for X MW between nodes (zones) i and
    j is entitled to receive the power X times the
    difference of nodal (zonal) prices between both
    nodes.
  • Physical implementation
  • Flowgates
  • Point-to-point

26
Transmission Rights Allocation Methods
  • First come first served
  • Proportional
  • Priority of use
  • Market splitting
  • Explicit auctions to allocate transmission rights
  • Implicit auctions
  • Explicit (long-term) implicit (short-term)
    auctions

Inefficient

Efficient
27
Efficient Congestion Management Methods
  • Explicit auctions, where the available
    interconnection capacity is allocated to the
    agents who submit the highest bids in an auction
  • On flowgates
  • Point to point
  • Implicit Capacity Allocation
  • Implicit auctions, where the available
    interconnection capacity is allocated to allow
    access to an organised electricity market by
    agents located on the other side of a congested
    interconnection, whose bids and offers are
    accepted. In this sense, the capacity is allocate
    implicitly on the basis of the energy market
    results
  • Market splitting, where the available capacity is
    used to support trading between different areas
    of the same organised electricity market. In this
    sense, the capacity is not allocated to
    individual agents.

28
Transmission Rights Allocated on a Flowgate
A
B
  • Typical case in cross border trading
  • TSOs agree on the available capacity between A
    and B
  • ETSO methodology NTC
  • This available capacity is allocated through
    auctions

Europe - Nordel
  • Probably the most sophisticated regional market
  • NordPool offers
  • Intra-day, continuous-trading physical market
    (Elbas),
  • Markets for electricity-based financial
    derivatives contracts (Eltermin).
  • Day-ahead, auction-based physical market
    (Elspot)
  • Clearing of OTC
  • Market splitting joint clearing of all national
    markets taking in consideration the capacity of
    links. When congestion arises, the market is
    split in several prices zones.

37
Europe - UCTE
  • Objective to ensure the coordination and
    co-operation for the safe and reliable operation
    of the interconnected electricity systems.
  • Mainly bilateral trading
  • Participants of a market can present offers in
    short term markets of another one
  • Congestion managements to trade, members must
    get cross border transmission capacity
  • Comprises several regions

41
Progressive Formation of Cross Border Markets
  • International experience show that cross border
    markets had an progressive integration of
    countries.
  • Experience gained with initial countries
    simplified the integration of new countries.
  • For instance
  • NordPool Norway-Sweden ? NS Finland ? NSF
    Denmark
  • Central America

  • Guatemala El Salvador
  • PanamaCosta Rica ? PCRNicaragua ?

  • A phased approach to CIS Electricity Market
    Integration

43
CIS Electricity Market
  • The CIS countries have agreed that the creation
    of the Common CIS electrical energy market shall
    be aimed at the improvement of the quality of
    service and security of customers.
  • They also foresee the implementation of CIS
    electricity market in a phased manner, so as to
    ensure the possibility of a gradual adjustment in
    the CIS countries economies to the market
    conditions as well as a secure energy supply.
  • Therefore the CIS power market does not exist
    yet, as a real market, although steps are being
    taken to establish this market.
  • A series of agreements exist that establishes the
    creation of a regional market based on the
    principles of equal rights, fair competition and
    mutual benefits,
  • Little additional progress has been made so far
    in the establishment of a formal market.

History
  • On February 14th, 1992, the CIS member states
    signed the Agreement on Coordination of
    Interstate Actions in the Field of Electric Power
    Industry of the Commonwealth of Independent
    States. This agreement created the CIS
    Electricity Council and its working body, the
    Executive Committee.
  • The active actions of CIS Electric Power Council
    member states promoted the stability of the
    situation and began the restoration of CIS states
    interconnected power system that was formally
    broken apart in 1998-1999 although some parts
    were already working independently.
  • In June 2000 the parallel operation of Russian
    UPS and the National Power System of Kazakhstan
    was restored. In September 2000 the power systems
    of Kyrgyzstan, Tajikistan, Turkmenistan,
    Uzbekistan were connected as the Central Asian
    interconnected power system, and then with the
    National Power System of Kazakhstan.
  • In August 2001 the Ukrainian and Moldavian power
    systems joined to the now interconnected power
    system of CIS states. Thus, the power systems of
    11 out of 12 countries are working now in
    parallel as one Interconnected Power System of
    Commonwealth of Independent States

46
Initial Conditions for a CIS Electricity Market
(I)
  • Three countries with competitive markets
  • Kazakhstan net pool with several participants.
    Single price. All participants allowed to
    import-export energy
  • Russia gross pool with nodal prices. Presently
    only InterRao allowed to import-export.
  • Ukraine moving to a net pool.
  • Rest of CIS countries with non competitive power
    sectors. In general no plans to move to multiple
    sellers-buyers competitive markets
  • Existing cross border transmission infrastructure
    that would allow regional trading

But, good news! There is enough cross border
transmission capacity. Lack of transmission
capacity is the only real obstacle to cross
border trading.
47
Initial Conditions for a CIS Electricity Market
(II)
  • Significant regulatory differences, that
    introduces seams and some obstacles
  • Diversity of physical conditions and primary
    resources , which implies good opportunities for
    trading
  • Possibility to start trading through bilateral
    contracts with no or only minor changes
  • Common market requires relevant regulatory
    changes
  • Real chance to obtain enhanced reliability, more
    efficient utilization of generating capacities
    and lower environmental impact with a CIS energy
    market

A relevant part of benefits can be achieved with
limited regulatory changes and with the reference
of international experience.
A phased approach would allow to obtain rapidly
benefits, while countries introduces the
regulatory changes that would allow maximize
benefits.
48
Towards fluent cross border trading
  • A highly integrated common market model would
    require relevant (and time consuming) regulatory
    changes in CIS countries.
  • A phased approach would enable to obtain short
    terms benefits with no or minimum regulatory
    changes.
  • Initially only secondary adjustments are
    necessary. As far as benefits from cross border
    trading are evident, there will arise incentives
    for entering in deeper regulatory changes.
  • Major regulatory changes can be progressively
    made after initial stages with the target to
    capture in the long term 100 of benefits
  • Several seams were identified, they diminishes
    the efficiency, but do not impede cross border
    trading
