• Where electricity is bought and sold, primarily by distribution and generation
companies for delivering it to end consumers.
• How is India’s wholesale electricity market structured?
• Decentralized, bilateral scheduling model
• Long-term PPAs which are physical contracts.
• A few market based products available in the PXs.

• Lack of imbalance management in real-time
• Small balancing areas incompatible with increasing variable RE
• Sub-optimal use of generation resources due to scheduling in
individual silos
• Cost of generation in any given time-block is undiscovered i.e. system
marginal cost

• Centralized platform for scheduling and dispatch
of resources in day-ahead and real-time.
• Market based bidding mechanism to ensure the
cheapest resources are being utilized.
• PPAs are proposed to be made into financial
contracts or hedges against market prices.
• Co-optimization of ancillary services with day-
ahead and real-time market.

Have you ever wondered
what if there was a centralized balancing
market?
what if there were no legacy
contracts?
what if there is market power
present?
how decentralized bilateral wholesale
market decisions are made?
how to make long-term investments in
capacity?
how to operate merchant vs contracted
plant?

• Player-driven simulation
• Experiment with various market designs and structures
• Switch between the roles of Discoms and Gencos
• Go through multiple rounds of gameplay to assess various
decision making behavior and its outcomes

• Distribution and Generation companies interact with each other under
different market designs, rules and time horizons.
• Players
• 3 Distribution Companies
• 6 Generation Companies
• 3 Automated Generation Companies*
• Three Stages
• Long-Term – contracting and investment decisions
• Day-Ahead – scheduling and procurement decisions
• Real-Time – imbalance management

Market Design – Decentralized Bilateral Long-Term Procurement
• Players start with some existing capacity.
• Gencos present long-term offers to each Discoms for new capacity
• Discoms can accept or reject offers
• Gencos can choose to build capacity as Merchants or leave it unbuilt

• Pair different scenarios with different market structures
such as:
• Less flexible capacity in the system
• No legacy contracts
• Level playing field
• Market power in generation
• Modular simulations
• Simulate specific stages in select scenarios as well
• Faster gameplay and focus on specific topics
