The main function of generating companies (GENCOs) are
To generate and sell electricity
To distribute electricity
To transmit electricity
All of above
To generate and sell electricity
Quick Summary: Generating Companies (GENCOs) are specialized entities within the restructured power sector responsible solely for the production of electrical energy. Their primary business model involves operating power plants (thermal, hydro, nuclear, solar, etc.) and selling the generated electricity to distribution companies or bulk consumers via wholesale power markets.

Pout=η×Pin — where Pout is the power generated and η is the conversion efficiency
Revenue=∑(Energysold×Pricemarket) — fundamental revenue model for a GENCO
In a deregulated power system, the vertically integrated utility is unbundled into three distinct functional entities: Generation (GENCOs), Transmission (TRANSCOs), and Distribution (DISCOMs). GENCOs function as independent profit centers that bid their capacity into a power pool or enter into long-term Power Purchase Agreements (PPAs) to supply energy, decoupling the production cost from the grid delivery and retail supply costs.
GENCOs do not own the transmission lines or the retail distribution infrastructure.
They focus on operational efficiency and optimization of fuel mix in power plants.
GENCOs participate in 'Economic Dispatch' to determine their optimal output based on marginal cost.
Market competition encourages GENCOs to minimize their Heat Rate for thermal power plants.
Increased operational efficiency through competition
Clear accountability and focus on generation technology
Incentivizes innovation in clean energy production
Market volatility in electricity spot prices
Complex regulatory oversight required to prevent monopoly at the generation level
Wholesale electricity markets
Merchant power plants
Captive power generation for industrial clusters
TRANSCOs are responsible for high-voltage grid infrastructure and bulk power delivery.
DISCOMs are responsible for retail service, metering, billing, and low-voltage delivery to consumers.
The Electricity Act 2003 in India was a milestone in enabling the unbundling of state utilities into GENCOs, TRANSCOs, and DISCOMs.
A is correct — GENCOs are strictly involved in the production of electricity and its subsequent sale to distribution entities or market pools.
Always remember that in an unbundled system, DISCOMs deal with the customer, TRANSCOs deal with the 'highway' grid, and GENCOs deal with the 'factory' (power plant).
