VIJAYAWADA: The State government has decided to extend Rs 10 lakh additional package to displaced families of the Polavaram Irrigation Project. A decision to this effect was taken by the State cabinet, which met on Friday under the chairmanship of Chief Minister YS Jagan Mohan Reddy. This will cause an additional cost of Rs 550 crore to the government. The decision was taken to fulfill the assurance given by Jagan Mohan Reddy to the displaced people of the Polavaram project.

Meanwhile, APGENCO and Megha Engineering and Infrastructures Ltd (MEIL) launched excavation works of the critical pressure tunnels of Polavaram hydroelectric power station on Friday. The officials have also chalked out a plan to expedite the works related to the 960 MW hydel power plant and complete it within the stipulated time.
