He said, "It highlights once again that India is adhering to all the provisions of Indus Waters Treaty."
The spokesperson also said the details of the award were being studied.
Pakistan has been objecting to the construction of the hydroelectric project on the Kishanganga river in Kashmir, which is called Neelum upon entering Pakistan.
In November 2009, Pakistan had proposed the establishment of a Court of Arbitration and the appointment of a neutral expert to resolve the Kishanganga dam dispute.
Indus Waters Treaty, inked between India and Pakistan, provides appointment of a neutral expert by the World Bank as a last option to resolve water related issues between the two countries.
The Kishanganga plant, in Bandipora district of north Kashmir, is part of a run-of-the-river hydroelectric scheme that is designed to divert water from the Kishanganga river to a power plant in the Jhelum River basin.
