To provide information for overseas investment in the power transmission industry and to offer references for China's power market reform

especially for transmission pricing

it takes Chilean transmission as an example to study the regulatory revenue model and transmission pricing mechanism.By studying the composition of transmission allowable revenue

cost allocation

and transmission tariff formation mechanism

it focuses on the two-part tariff recovery method for transmission system costs

the zonal pricing mechanism for transmission congestion charges

and the postage stamp allocation method.The study shows that in terms of the recovery of investment in the transmission industry

Chilean transmission has a stable and continuous revenue mechanism with a clear revenue guarantee mechanism.In the process of power market construction and reform

Chile formes a transmission pricing mechanism that is relatively simple and clear and takes into account certain transmission congestion management

while also being linked to the electricity spot market.For investors

Chilean transmission industry has a clear and guaranteed revenue mechanism.For China's electricity regulation agencies

the experience of the Chilean case can be used as a reference to explore the construction of a transmission pricing mechanism that simultaneously reflects the locational signal of prices and transmission congestion management

and to gradually achieve effective coordination between the reform of transmission and distribution tariffs and the electricity spot market.
