Polavaram project issue became powerful weapon to all political parties. Ruling party's interest is to complete the project and gain politically where as oppositions are trying to show out govt's corruption. The main point of criticism over the project is substantial increase in estimated cost of Rs 54,000cr from the initial cost Rs 10,000cr. Regarding increased expenditure, Chandrababu gave clarity in the Assembly that the cost had increased by 10 times due to newly amended act, delay in the project, & R&R package. On the other hand, contractor problem is causing hurdles in the completion of the project, he added.
