The GENCOs sell electricity to
Transmission companies
Direct customer
Entities who have negotiated sell contract with them
Distribution companies
Entities who have negotiated sell contract with them
Quick Summary: In a deregulated electricity market, GENCOs (Generating Companies) do not sell electricity to a single entity. They operate on a contractual basis, selling power to any entity that has negotiated a Power Purchase Agreement (PPA) or via market mechanisms, which can include distribution companies, large industrial consumers, or power traders.

Pcontract=∑i=1n(Ei×Ti) — Total revenue calculation based on energy E at negotiated tariff T
Post-deregulation, the vertical integration of power utilities is unbundled. GENCOs focus solely on production and enter into contracts—either long-term PPAs with DISCOMs or short-term agreements through power exchanges—to sell their generated capacity or energy output. These contracts are legally binding instruments that define the tariff, duration, and quantity of power supplied.
Unbundling separates Generation, Transmission, and Distribution.
GENCOs are independent entities in a competitive market.
PPAs (Power Purchase Agreements) serve as the primary legal foundation for electricity trade.
Market clearing price is determined by the intersection of supply and demand bids in power exchanges.
Increased operational efficiency due to competition.
Greater choice for consumers and entities to source power.
Complexity in contract management.
Potential volatility in market-clearing prices.
Wholesale electricity markets
Merchant power plants
Captive power supply arrangements
GENCOs focus on asset utilization and minimizing variable cost (fuel/O&M).
Option D is incomplete because, while DISCOMs are primary buyers, GENCOs can also sell to other entities like industrial consumers or via open access, making C the most technically accurate and comprehensive answer.
C is correct — GENCOs are independent power producers that sell their generation to any entity, such as distribution companies or large consumers, with whom they have established a legal contractual agreement.
Always remember that in a deregulated market, 'Transmission Companies' (TRANSCOs) generally provide service as common carriers and do not purchase power; they only manage the infrastructure.
