Indian Power Sector One of the largest interconnected power systems in the world Generation Capacity of 164,836 MW(Sep 2010)-800,000 GW by 2030 Energy deficit of about -9.6% and peak demand deficit of -10.5% (Sep 2010) Predominant focus on fossil fuels, especially coal Source: CEA, NLDC *Deficit numbers for Jan 2010

Indian Power Sector Demand – Supply Summary Forecasts Even with higher rates (6% y-o-y) of capacity addition and energy generation, India would continue to remain a power deficit country Source: CEA*Extrapolated by PXIL

India’s Projected Energy & Capacity requirements Immense task ahead in terms of capacity addition requirements

ROLE AND IMPACT OF POWER EXCHANGES IN ENERGY MARKET DEVELOPMENT

Electricity Act transition to a market Development of a multi-buyer multi-seller market in power Compulsory Unbundling of utilities Complete De-licensing of generation “Trading” of Electricity – a licensed activity Provides Consumer level choice of supplier Separation of “transmission ownership” and “system operation” Universal Open Access to transmission networks for all consumers over 1 MW Robust Policy framework providing ground rules for competition National Electricity Policy detailing roadmap for development of markets - PXs Mandated Competitive procurement of power by uitilities Global competitive bidding for projects in transmission A proactive approach for development of a market in renewables Committed the Nation to Development of a Vibrant Market in Electricity

Volumes Transacted  Volumes on Exchanges have shown an increasing trend as percentage of total generation  Proactive approach from the regulator and efficient grid management by the system operator  Absence of Universal Service Obligation on Utilities resulting in reduced demand  Volumes on Exchanges have shown an increasing trend as percentage of total generation  Proactive approach from the regulator and efficient grid management by the system operator  Absence of Universal Service Obligation on Utilities resulting in reduced demand

Prices Average Price of electricity Traded over Exchanges  2008 Rs. 7.57/kWh*  2009 Rs. 5.73/kWh Traded in OTC market  2008 Rs. 7.04/kWh  2009 Rs. 6.41/kWh Prices in 2010 exhibit a further declining trend. * Exchanges were in operation only during the last three quarters of the year  Efficient Price Discovery leads to Lower prices on exchange  Softer Prices at the exchange cast a spill over effect on the OTC market  Efficient Price Discovery leads to Lower prices on exchange  Softer Prices at the exchange cast a spill over effect on the OTC market

KEY ISSUES AND CHALLENGES

Electricity Act transition to a market Compulsory Unbundling of utilities Complete De-licensing of generation Separation of “transmission ownership” and “system operation” Universal Open Access to transmission networks Consumer level choice of supplier Development of a multi-buyer multi-seller market in power The intent and the ethos of EA 2003 towards creating competition at the utility level as well as the end customer level is still elusive

Key issues and Challenges- Multiple State level markets Mixed response to national legislation Multiple States and Jurisdictions Many still vertically integrated Isolated nearly self sufficient markets Open Access to transmission lines controlled by State Transmission Utilities Limited Inter - connector capacity Inter-connector capacities not with the exchanges Exchanges and OTC compete for capacity

Creating Markets Historically illiquid market Planned dependence on PPA-only 8% of electricity produced traded through short term market Trading of electricity only a few years old A stable Day Ahead spot market on the Exchange Pricing Challenges Long term price view yet to emerge Declining trend in merchant power prices-with near zero cost of avoidable load Exposure to international coal prices-consumer level pricing shocks ? Sudden Unrestrained growth High capacity addition might lead to excess supply or stranding Issues on fuel availability /fuel mix may emerge in the long run

Transmission Pricing Infrastructure 5 Electrical Regions, More than 25 Control areas Transmission constraints across regions Transmission pricing based on tenure of transactions Long Term – More than 25 years  Transmission access given for specific seller and buyer  Transmission pricing based on cost of asset and socialized over all beneficiaries in the Region Short Term – Upto 3 months  Transmission access given for each transaction separately for a specific seller and buyer pair  Transmission pricing arrived at as a percentage of long term transmission pricing  Earnings used to reduce the cost of asset for long term transmission consumers Day-Ahead Spot Market – For the next day only  Transmission access for trades through Power Exchanges - Collective transactions  Point of connection tariff – equal price for connection from anywhere in India Balancing – Real time  Power system frequency based pricing  Penalty or reward based on deviation from schedule in any 15 min time block

Transmission Access Priority to Transmission Open Access given to Long term, followed by Short term and then power exchanges Based on timing of application for Short Term Congestion charge applied only on transactions happening through PXs Different Products treated differently Collective transactions for DAS FCFS for Term Ahead (Weekly) Product

FUTURE OUTLOOK

Renewable Energy Certificates Market based instruments for trade between the Eligible Generating firms and Entities carrying Renewable Obligation Initially Non-transferable contracts, mandated to be traded on PXs Energy Efficiency Certificates Market based mechanism to promote energy efficiency in 9 identified industrial sectors Firms maintaining higher efficiency than set Targets would sell certificates whereas firms with lower efficiency would need to buy Industrial consumers also carry renewable purchase obligation Mainstreaming Environmental Products PXs evolve from being voluntary to mandated platforms

Delivery Based Forwards Monthly Contracts  CERC has initiated the process to develop the product attributes to suit the market  For delivery contract Ancillary Services Contract Concept paper floated by NLDC Financial Products Envisaged in future Longer Tenure Products

Future Outlook - PXIL PXIL remains committed to delivering to its participants contextual products and services on the following principles Accessibility Affordability Reliability Quality Availability
