This line is the first inter-regional link between eastern region and western region, an official statement said.
The Prime Minister also inaugurated commencement of work at state-run NTPC's thermal power plant (3x660 MW) at North Karanpura at Chatra in Jharkhand.
Central transmission utility Power Grid Corporation has implemented the Ranchi-Dharamjaygarh-Sipat inter-regional transmission line at a total cost of Rs 1,600 crore.
Two new sub-stations have been built at Ranchi in Jharkhand and Dharamjaygarh in Chhattisgarh, the statement added.
The benefits of the project include augmentation of inter-regional capacity of eastern region with western region, thereby facilitating exchange of surplus power between eastern and western region, depending on the availability of generation and load demand in each region.
Surplus power from eastern region can also be transferred over this link to western region for onward transfer to southern or northern region.
NTPC is already supplying about 298 MW power to Jharkhand from its various power stations. Jharkhand will get around 230 MW from this project.
In addition 354 MW has been allocated by Ministry of Power to Jharkhand from other new and under construction projects of NTPC.
Addressing the function on the occasion, Power Minister Piyush Goyal said that though NTPC project in Jharkhand was started more than ten years ago but because of lack of coal linkage and several other issues, the power project could not take off during the period.
He said the centre is keen to provide separate feeder line to farmers in the state.
Referring to the underground fire in Jharia coalfield, Goyal announced the Union Government will provide Rs 100 crore for controlling the underground fire.
