2007 • CERC issued guidelines for setting PX• IEX got in principle approval
•• Day Ahead Market (Collective t/s)
commenced upon approval from CERC
Sep 2009 • Term Ahead market for Forward electricity contracts started
June 2008
Feb 2011 • Renewable Energy Certificate (REC) tradingcommenced

BID MATCHING
Open/Closed Auction
Orders accumulated during call phase (no matching)
Orders matched after call period
Orders are used for calculation common price
i.e. Equilibrium Price.
All successful orders matched at Equilibrium
Price.
Continuous Trading
Price-time priority based continuous matching
The highest Buy order & lowest Sell order gets the
priority
If the prices are same then priority is given to the time
of the order received.

Algorithm of Price Calculation
• Step 1: Unconstrained Solution (w.r.t. Transmission Capacity) - Find MCP and MCV; Demand=Supply on aggregated net curve.
• Step 2: After receiving the actual ATC, examine bid area for bottlenecks.• If a bottleneck is found, the market is split in two partial calculation area:
Source (surplus) and sink (deficit).• A new ACP is found in both source and sink.
- Surplus Lower ACP than MCP- Deficit Higher ACP than MCP.
• Each partial calculation area is examined for bottlenecks in the same way.• When no more bottlenecks are found internally in the calculation area, the
recursion stops.
Case Synopsis-I• Illustration of Price Matching and Market Splitting.• Two regions have been considered i.e. ER and SR.• Four Sellers and Two Buyers in a 15-Min Block are taken with following Bid Scenario: -

Demand and Supply gap in two regions get balanced by unconstrained flow between the tworegions hence a common MCP is derived.

Constraint Solution (Market Splitting)
Congestion was reported by NLDC from ER to SR corridor and flow is constrained to 100MW.Due to flow constraint, system will “Split” the market in to two regions i.e. Deficit (SRRegion) and Surplus region (ER Region),and will again run the calculation chronology forboth the regions separately considering the flow constraint and will derive the ACP and ACV.
