Aggregators is the entity which
Combine all transmission companies
Combine customer into buyer groups
Combine all distributors
Combine all generator groups
Combine customer into buyer groups
An aggregator in a deregulated power market acts as an intermediary that pools together the demand or generation from multiple small-scale consumers or producers ┬╖ By combining them into a single buyer group, the aggregator gains sufficient market volume to participate in wholesale electricity auctions and negotiate better pricing terms on behalf of the consumers.

The mechanism relies on economies of scale ┬╖ Individual small consumers (like residential or small commercial units) often lack the load capacity to interact directly with the wholesale electricity market or the Independent System Operator (ISO) ┬╖ The aggregator performs the roles of load forecasting, bid submission, and settlement, reducing individual risk and operational complexity for the end-users.
Aggregators enhance market liquidity by enabling small participants to enter the wholesale market.
They provide Demand Response (DR) services to the Grid Operator/ISO by shifting or reducing aggregate load.
The aggregator acts as a 'Virtual Power Plant' (VPP) when managing distributed energy resources.
Deregulation creates the necessity for entities that can manage heterogeneous portfolios of assets.
Improved bargaining power for consumers in wholesale electricity markets.
Facilitates demand-side management which reduces grid stress during peak hours.
Introduces an additional layer of complexity in billing and settlement.
Privacy and data security concerns regarding consumer consumption patterns.
Smart grid demand response programs.
Pooling distributed solar or battery assets for grid services.
Option A is incorrect because transmission companies are infrastructure owners, not entities that require aggregation of demand.
Option C is incorrect because distributors (DISCOMs) are the entities that buy from the market/aggregators to supply end-users.
Option D is incorrect as generators are suppliers of energy, while aggregators primarily focus on the demand/consumer side or small-scale distributed supply.
B is correct тАФ Aggregators function by consolidating the power demand of multiple smaller consumers into larger, marketable blocks to interact with wholesale electricity markets.
In competitive power system exams, always distinguish between the Aggregator (demand-side/market participant) and the Independent System Operator (ISO/system coordinator).
