Development of intra-day market
 Regulator roadmap promoting intra-day cross-border market.
An international intra-day market would be the best solution
 As APX Eurolight trading system allows fast implementation
and members support this:
 APX has started up national market, precursor to international
 Willingness to develop this further with international partners

Market transparency
 Report EC competition highlights market information
 Information e.g. on maintenance and outages of power plants, is
needed, especially for non-incumbent players or investors.
 A good system of market information for power, gas, emissions is
needed. APX supports and facilitates initiatives

The benefits of implicit auction
(market coupling)
From 2-step process: 1) capacity auction
2) spot market,
Now 1-step process: spot markets & integrated cross-border
auction
 All local players play internationally; better liquidity, transparency
When there are transmission constraints:
 Capacity always used to the maximum, most optimal way
 Guaranteed 100% use it or lose it + netting of im/exports
When there is no real constraint:
 Market coupling unifies markets / prices
 For x % of time, markets merge:  “part time copper plate”
 Integrated European electricity market

System development
 Current APX and Powernext systems for spot market
 Prototype for 2 markets
 Prototype for 3 markets (somewhat more complicated)
 Trilateral market coupling development
 Joint development of APX and Powernext: central coupling
module, local modules, iteration rules
 Calculation for each hour: straightforward, no iterations
 Calculation with multi-hour blocks: iteration needed
 Development for X markets: underway
 Multilateral market Coupling (MLC)
 European development

region: countries become price zones
Outcome depends on market forces, transmission constraints:
F ≠ B ≠ NL
F ≠ B = NL
F = B ≠ NL
Latest news
On 27 October 2006, the three regulators
from the three countries approved this.
Start of trading according to this coupling is
scheduled for 21 November 2005

Linking two regions
 NorNed cable links two regions,
already internally coupled:
– TLC region Netherlands,
Belgium, France
– Nordic region Norway, Sweden,
Finland, Denmark
 Steering committee established:
– 4 exchanges APX, Belpex, Nord
Pool, Powernext
– 4 TSO’s Elia, RTE, Statnett,
TenneT
 Aim at an enduring solution with
European scope
 Possible interim solution for livedate of cable October 2007
Page 29
Develop an enduring solution
Enduring solution:
 MMC = Multilateral Market
Coupling
 Optimize Nordic and TLC region
 “Open solution, other interested
parties will be invited to
contribute as the project
progresses” *
 E.g. Spain, UK, Germany,
Poland, Baltic countries, others
 Able of coupling many regions
 Flow-based, able to handle loop
flows
* Paper by Statnett, TenneT, Elia, RTE, Nord Pool Spot, APX, Belpex and Powernext presented at the “mini-forum” organised by the regulators on
the central North-West European electricity market, 20 June 2006
Page 30
Open system, more possibilities
 Parties committed to
facilitating the addition of
further areas to the
approach, open to any other
new partners (Iberian
peninsula, Italy, UK/ireland,
Germany, Central Europe,
Eastern Europe)
 Fits with “Regional Markets”
approach as foreseen by
European Commission,
European
Regulatory Forum

Mix of implicit and explicit auctions
Scandinavian model:
only daily cross-border
 No auction of longterm capacity
 All capacity daily
allocated in market
“splitting”
 Long-term contracts
are financial
Central European model:
mix of daily and long-term
 Explicit auction for
monthly/yearly capacity
 Daily capacity auction,
explicit or implicit
(=market coupling)
 Both physical and
financial cross-border
contracts
Re-trading / settlement
should be possible
 Submit long-term
capacity for reauctioning, getting
implicit auction value
 “Use it or sell it”
 Use physical right as a

Summary
North West European market is integrating fast
 First step: Belpex + coupling France – Belgium – Netherlands
Trilateral Market Coupling (TLC)
 Based on intensive co-operation between exchanges, TSO’s
 Due to start soon
A VITAL LINK IN ENERGY TRADING
 Next step: NorNed cable: connect TLC and Nordic regions
Towards an enduring an Multilateral system
Towards a enduring European, flow-based solution
 Open and accessible system, suitable for more countries
 Other exchanges/countries invited to comment and contribute
