2. Main principles in Elspot What is Elspot? n Nordic Market place for purchases/sales of electric power - gives overall planned balance day-ahead n Short-term physical contracts l l Duration of one hour 12 -36 hours ahead (next day’s 24 hrs. ) Trading 365 days a year Three bid types: hourly, blocks, and flexible hourly bids n Bidding with portfolios in purchase/sales curves n Auction trading (once per day) n Price set at equilibrium point (buy=sell) each hour n Handling of bottlenecks between Elspot Areas using the so called Price Area Model (Market Splitting) Copyright Nord Pool ASA 2002 Demand Supply
Bidding Areas in the Elspot Market Balance requirement : NO 2 E NO 1 FI SE Participants must achieve balance between energy supply and energy demand within each bidding area (including contracts) towards TSO Participants must be approved as Balance Responsible Company by the national TSO in the area(s) they intend to trade in. (In some countries this can be handled via a third-party agreement with a BRC). DK 1 DK 2 Note: In Norway the number of Areas vary over time and currently there are four areas Participants place bids in Areas where they are approved (”BRC”) and have production, consumption or contracts
3. Handling of congestion in Elspot Price calculation - no bottlenecks Elspot Areas 1. Calculation of system price 2. Checking transmission limits Price Purchase NO 2 Sale One price Ps E NO 1 SE FI Trade MW DK 1 DK 2 Area prices = System Price
Price calculation - with bottlenecks 2. Checking transmission limits Elspot Areas 1. System price calculation NO 2 E NO 1 SE Purchase Sell Flow at System Price above capacity, thus different prices Ps FI DK 1 DK 2 Physical power flow 3. Calculation of different Elspot area prices (iterative process) Copyright Nord Pool ASA 2002
Calculation of area prices when bottlenecks occur Example: System Price calculation results in a flow from Sweden to Norway above capacity (C). System Price D S Price Area Sweden D Swe +exp S Swe Price Area Norway S Nor +imp D Norway price System Price Sweden price C C n Solution like above: Flow is ”geared down” to max. transmission capacity (C) by the price-mechanism. Export (Swe) and import (Nor) will be equal to available capacity (C). n Result: Norway price > System price > Sweden price Participants are always credited/debited according to the Area Prices.

4. Possibilities and limits for usage in other countries and regions Elspot’s Price Area Model - ”Market Splitting” n Allocates transmission capacity based on the energy bids, thus Elspot is a simultaneous energy and capacity auction n Results in energy flows according to price signals n Opens up national and international trading for all types of companies n Bilateral contracts between parties in different countries can easily be agreed upon and then reflected in Elspot bids (buy/sell) per bidding area n Reduces market power because the model connects areas/countries and importantly it is done in a non-discriminatory fashion Copyright Nord Pool ASA 2002 (flow from low high price)
Various ways of handling cross-border Power trading and congestion Integrated market Nord Pool Model (Market splitting) Daily auctions Long-term auctions Bilateral agreements Isolated markets Copyright Nord Pool ASA 2002
