The gross grant included Rs 417.44 crore for the Polavaram multipurpose project, one of the issues of contention between the allies TDP and BJP.
"The release (of Rs 417.44 crore) is towards the amount already utilised by the state against the irrigation component (of Polavaram) after April 1, 2014," an order issued by the Union Water Resources Ministry's senior joint commissioner, RPS Verma, said.
The centre, through the Polavaram Project Authority, had so far released Rs 4,329 crore for the project while the state government said it spent over Rs 7,200 crore after it was declared a national project.
Andhra Pradesh Finance Minister Yanamala Ramakrishnudu submitted a memorandum to Union Finance Minister Arun Jaitley last month stating that a sum of Rs 3,217.63 crore, spent on Polavaram, was yet to be reimbursed to the state.
Of this, the centre has now released Rs 417.44 crore, an official of the water resources department in Amaravati said.
The centre, meanwhile, also released Rs 369.16 crore last night under post-devolution revenue deficit grant, as per the recommendation of the 14th Finance Commission, to Andhra Pradesh.
"They shall be open to inspection by an officer deputed by the Government of India or the state government," an under-secretary at the centre said in the release order.
The centre also released Rs 253.74 crore as 'basic grant' to urban local bodies in the state. This was the second instalment during the current financial year.
Apart from this, a sum of Rs 196.92 crore was released for the anganwadi services scheme and the supplementary nutrition programme and another Rs 31.76 crore was released for the Mahatma Gandhi National Rural Employment Guarantee Programme, a state official said.
The TDP had been at loggerheads with the centre over the "raw deal" given to the state in the Union Budget 2018-19 and the party lawmakers protested in Parliament on the issue saying no specific allocations were made to the state.
The party was particularly peeved that the Polavaram project was seemingly ignored in the central allocations.
