State Reports (Vol.-III)
Study on `Impact of Restructuring of SEBs’
For obtaining coal for the new power plants, GSECL would most likely be required to
own and operate coalmines and coal washeries. Some advance action to scout for a
partner and form a joint venture to own and operate coalmines may have to be taken
quickly. Also, the option of finalising long-term contracts for imported coal will also
need to be explored. These issues are also important in ensuring improved
performance of existing thermal generating plants and are required to be sorted out
quickly so as to ensure that savings anticipated from improved performance do
materialise.
GUJARAT ENERGY TRANSMISSION CORPORATION LIMITED (GETCL)
GETCL’s transmission network comprises of 400 kV to 66 kV lines and sub-stations
spread across the State for evacuation of generation from GSECL, IPPs and State’s
share of power from central sector projects and delivering the power to distributing
companies. Details of the transmission in the State are as under:
Details of existing Transmission Lines and Sub-stations
