In vertically integrated electrical utility, The information flow is in between
Generation and customer
Transmission/Distribution and customer
Generation and Transmission/Distribution
Generation, Transmission/Distribution and Customer
Generation and Transmission/Distribution
Quick Summary: In a vertically integrated utility model, the same entity owns and operates the generation, transmission, and distribution assets. The primary information flow is internal, occurring between the Generation department and the Transmission/Distribution (T&D) department to ensure real-time balancing of supply and demand.

Pgen=Pload+Ploss — Fundamental power balance constraint in integrated utilities.
The vertical integration relies on centralized dispatch. The Generation control center continuously communicates with T&D dispatch centers to adjust output (using Automatic Generation Control or AGC) based on load forecast and network constraints within the same utility framework.
Vertically integrated utilities operate as natural monopolies.
Information flow is centralized under a single management system.
The model minimizes third-party transaction costs but lacks market price signals.
Operational data exchange focuses on reliability and stability.
Simplified operational coordination
Economies of scale in management and maintenance
Lack of competitive pricing
Potential for inefficiency due to absence of market pressure
Traditional state-owned electricity boards
Isolated grid networks
In deregulated models, information flow expands significantly to include market participants and independent system operators.
Option A is incorrect because the customer does not actively participate in the technical flow of dispatch information in a traditional utility.
Option B focuses on the delivery side, ignoring the core power balance coordination requirement.
C is correct — Information flow is primary between Generation and Transmission/Distribution to maintain the fundamental power balance (Pgen=Pload+Ploss).
Always remember that in restructured power markets, the information flow shifts from internal utility communication to an open market-clearing mechanism involving Power Exchanges (PX) and ISOs.
