• Surplus transmission capacity
• Deviation Settlement Mechanism
– Single-Buyer Model will not need
• Payment Security
– Nodal agency model (eg PTC) will take care
• Method for determination for surplus transmission capacity
determination
– Nodal agencies for ATC calculations specified
For examples, India-NLDC and Nepal – NEA.
– Both countries will determine ATC considering downstream networks
– ATC in both directions calculated
– Min of ATCs specified by both NAs in each direction declared as ATC
Cross-Border Exchange Necessary Conditions
www.iexindia.com
Cross-border ExchangePossible models … phased development
• Stage 1/Option 1: PTC as Nodal Agency
– Indian Power Trader PTC India Ltd made nodal agency for all the transactions
of Nepal.
– IEX deals with PTC and PTC will further deal with Cross-border participants
• Stage 2/Option 2: A Cross-border trader as Nodal agency
– Cross-border Member having government’s mandate and guarantee
– IEX deals with the Member and he further deals with local participants
• Stage 3/Option 3: Nepal Power Exchange as Nodal Agency
– Cross-border Power Exchange becomes nodal agency
– The Exchange collects bids of all participants and then forward to IEX
www.iexindia.com
Stage 1/Option 1: PTC as Nodal Agency
• There will not be any need to make any changes in the
present regulation and orders
• As a power trader PTC can handle finance of the clients
• PTC will bid and clear on behalf of Nepal clients
• The payment security mechanism will be taken care by PTC.
• PTC will be handling Clearing & Settlement arrangement:
– They may collect payment/funds for a longer period , before trade or
after trade
– They will do all the Co-ordination for C & S across the border
www.iexindia.com
Stage 2/Option 2: Cross-border trader as nodal agency
• As per current regulation, only Indian company can become
member of IEX.
• Will need to make changes in the Regulation of both the countries
• International fund transfer/payment to work out.
– International money transfer is time consuming
– 100% Payment/ fund for trade from the parties will be collected in
advance
• Risk hedging of other participants may become an issue due to the
international participants through out of the country member
• Local member can give advisory to local participants
www.iexindia.com
Stage 3/Option 3: Cross-border power exchange as nodal agency
• Comprehensive Regulation s need to be put in place
• Market price and volume determination issues:
Option 1: Common price for all the participants
⁻ Local power exchange only collects the bids and pass on to IEX for
common price and volume determination
⁻ This will give a common price signal to all the participants
Option 2 : Surplus bids passed to Host Exchange
⁻ Two different prices- Local Exchange Price and IEX price
⁻ Local exchange 1st runs the solution and sends the un-cleared
volume to IEX
⁻ Advantages of bigger markets not available to local participants

– Area prices different across congested corridors
– Transmission capacity allocated through
implicit Auction – no separate auctions for
transmission
– Best method to handle energy + transmission
together in one trade session
– Favoured by European Commission for Internal
Electricity Market in coupling all Central
European, Nordic and Et European markets
Handle Transmission Congestion Market splitting manages energy and transmission together
www.iexindia.com
Transmission Congestion Fund Utilize for Transmission Corridor Development
• Congestion fund = (Buy & Sell Volume difference) * (Difference
in price of interconnected bid areas)
