Step 1 2015

Step 2 2016

Step 3 2018-2020

Expand use of the nationwide grid

(to be undertaken approximately by 2015)

Complete liberalization of the retail electricity sector

(to be undertaken approximately by 2016)

Establish legal separation between electricity

generators and distributors and abolish retail price

regulation. This will allow more flexibility in balancing power needs between regions in order to ensure supply when power demand and supply is tight.

This will allow consumers to choose their supplier and charging system.

Separate the generators and distributors into independent and neutral entities to allow an accessible and independent power grid. Furthermore, the retail price of electricity will be completely liberalized to ensure competitive electricity pricing.

Organization for Cross-regional Coordination of Transmission Operators will be established
