Organized systems for trading electrical power between generators, retailers, and consumers through complex pricing mechanisms and regulatory frameworks.

Electricity Markets

Electricity markets represent the complex economic and operational frameworks through which electrical power is traded, distributed, and monetized in modern economies. These markets have evolved from traditional monopolistic utilities to increasingly sophisticated trading systems that balance supply, demand, and grid stability.

Market Structure

Wholesale Markets

Day-ahead markets where generators bid to supply power
Real-time balancing markets for immediate adjustments
Capacity markets ensuring long-term supply adequacy
Integration with grid operations for system reliability

Retail Markets

Competitive supplier selection in deregulated regions
Fixed vs. variable rate structures
Consumer choice programs
Integration of distributed energy resources

Price Formation

Electricity prices are determined through complex interactions of:

Fuel costs and generator efficiency
transmission constraints
Weather patterns and seasonal demand
renewable energy penetration levels
energy storage capacity

Market Participants
