The organization of the electricity sector 4 models (evolution over time):
S U P P L Y GENERATION High Voltage customers TRANSMISSION MV & LV customers DISTRIBUTION Pre-liberalization Model:Monopoly Vertically integrated (usually state-owned) company Imports, Exports Electricity flows Contracts
. . . Full competition model (1) (wholesale, retail cash flows) Contracts - centralized market Imports Generator1 Generatorn Centralized market Supplier n supplier1 Supplier 2 Exports consumers consumers Wholesale Retail
. . . Full competition Model (2) (wholesale, retail cash flows) Bilateral Contracts Imports Generator 1 Generatorn Supplier n supplier1 Supplier 2 Exports consumers consumers Wholesale - bilateral Retail
. . . Full Competition Model Electricity flows Imports Generatorn Generator 1 Transmission System (MONOPOLY) Supplier Consumers HV Distribution Company 1 Distribution Companyn Consumers (LV, MV) Consumers (LV,MV) exports
Full Competition Model The actors (by order of competitive behavior) More Competition Less/No Competition
