Agreeing to hear the plea of National Thermal Power Corporation (NTPC), a bench of justices Vikramajit Sen and S K Singh issued notice to the state government.
Solicitor General Ranjit Kumar, appearing for the company, contended that the construction was already going on when the apex court passed the order and its project is not situated in the eco-sensitive zone.
The apex court had on August 13 last year prohibited setting up of any new hydroelectric power project in the state and directed the Centre to constitute an expert body to study environmental degradation caused by such projects.
The court had directed the Ministry of Environment and Forests and the Uttarakhand government not to grant any further environmental or forest clearance for any hydroelectric power project until further orders.
