Formal dedications or inaugurations of significant public infrastructure projects in India are ceremonial events. Depending on the scale and central-government sponsorship of the project, they are performed by a designated high constitutional functionary — most commonly the President, in the President’s capacity as ceremonial Head of State, for flagship central-sector infrastructure — and are documented through official press releases from Rashtrapati Bhavan or the Press Information Bureau.

The 726.6 MW OTPC (ONGC Tripura Power Company) Palatana power project — a joint-venture power project in India's north-east promoted by ONGC (a Government of India public-sector undertaking), IL&FS, and the Government of Tripura — had the first unit of its plant formally dedicated to the nation on 21st June, 2013, during an official visit to Tripura. This ceremony was carried out by the then President of India, Pranab Mukherjee.

This is corroborated by the official press release on the President of India's website and by contemporaneous national reporting (Press Information Bureau, Economic Times, Business Standard, and Times of India), all of which record President Pranab Mukherjee — not the Prime Minister, the Chief Minister of Tripura, or the Vice-President — as the dignitary who performed the dedication ceremony:

• Chief Minister of Tripura heads the elected state government of Tripura and administers state-level programmes and schemes, a role distinct from the Union-government-level dedication ceremony held for this project.

• Prime Minister of India heads the Union Council of Ministers and exercises the country's chief executive authority, a role distinct from the ceremonial Head-of-State function exercised at this event.

• Vice-President of India holds the second-highest constitutional office in the country and serves as the ex officio Chairman of the Rajya Sabha, a role with no dedication-ceremony function attached to this event.

Hence, the Palatana Power Project was inaugurated by the President of India, Pranab Mukherjee, on 21st June 2013.
