The basic issue of deregulation is
Government has no control on power system operation
Government has no control on price of unit generation
Government has no control on transmission network
To manage economical, secure and stable operation of power system
To manage economical, secure and stable operation of power system
Quick Summary: Deregulation is the restructuring of the power industry to transition from a monopoly (vertically integrated utility) to a competitive market environment. The core objective is to replace rigid government control with market mechanisms to ensure the power system is managed economically, securely, and reliably.

Ctotal=∑i=1nCi(Pi) — Total cost function to be minimized under competitive bidding
Pload=∑Pgen−Ploss — Fundamental power balance constraint for system stability
The principle involves unbundling the vertically integrated power sector into separate segments: Generation, Transmission, and Distribution. By introducing competition in generation and retail, and providing non-discriminatory access to transmission networks, the goal is to optimize efficiency through market-clearing price discovery while maintaining technical stability through Independent System Operators (ISOs) or Regional Transmission Organizations (RTOs).
Deregulation facilitates the entry of multiple power producers.
Transmission remains a natural monopoly and is regulated for non-discriminatory access.
System security and reliability standards are enforced by an ISO.
Market-based pricing replaces traditional cost-plus tariff structures.
Increased operational efficiency
Lower prices due to competition
Increased innovation in supply and technology
Increased market volatility
High complexity in network coordination
Risk of market manipulation
Electricity Wholesale Markets
Smart Grid Integration
Renewable Energy Integration
The transition from state-owned monopoly to competitive market is often termed 'Restructuring'.
Options A, B, and C are incorrect because, while deregulation reduces direct government intervention, the state retains critical roles in policy, safety, reliability, and ensuring equitable transmission access, rather than having 'no control'.
D is correct — The goal of deregulation is to utilize market competition to enhance efficiency while ensuring the power system remains secure, stable, and economically optimized.
Always remember that in power systems, 'deregulation' does not mean 'no regulation'; it means shifting from 'command-and-control' to 'rule-based competition' to maintain the N−1 reliability criteria.
