Systematic frameworks for pricing electrical power consumption that balance utility costs, consumer behavior, and regulatory requirements while promoting efficient energy use.

Tariff Structures

Tariff structures form the economic backbone of power distribution systems, establishing the framework through which utilities recover costs and consumers pay for electrical services. These pricing mechanisms serve multiple objectives, from ensuring utility financial viability to promoting energy efficiency.

Basic Components

Fixed Charges

Variable Charges

Common Tariff Types

Flat Rate Tariffs

Single rate per kilowatt-hour
Simplest structure
Limited incentive for energy conservation
Commonly used in residential sectors

Time-of-Use (TOU) Tariffs

Different rates for peak/off-peak periods
Promotes load balancing
Encourages demand response
Requires smart meters

Demand-Based Tariffs

Charges based on maximum power demand
Common in industrial loads
Influences power factor correction
Promotes efficient capacity utilization

Advanced Structures

Dynamic Pricing

real-time pricing
