The acquisition will make it the largest private operator of hydroelectric plants in India, the company said in a statement.
"The consortium agreed to purchase the Baspa Stage II and Karcham Wangtoo plants in the northern state of Himachal Pradesh, from Jaiprakash Power Ventures Ltd, a subsidiary of Indian infrastructure conglomerate Jaypee Group," it said.
TAQA, which holds 51 per cent stake in the consortium, will have control of operations and management of both the facilities under the proposed deal, it said.
TAQA said: "The equity invested by the consortium in the acquisition of the two hydroelectric plants will amount to approximately Rs 3,820 crore (USD 616 million, based on Mar 1 2014 foreign exchange rate), of which 51 per cent is from TAQA."

The consortium will also acquire the assets' non-recourse project debt.
TAQA's Executive Officer and Head of Global Power & Water Frank Perez said: "India's economic growth depends on having ample and reliable energy supply. TAQA is pleased to add these two high quality hydro power assets to our growing India business and to support India's economic growth."
The plants are 35 km from the Sorang hydroelectric plant, in which TAQA acquired stake last year.
Following the completion of the transaction, TAQA's gross operational power generation capacity in India will rise to 1,741 MW, comprising of 3 hydel power and one lignite plants.
