Christopher Longbottom died after an incident at the power station
Christopher Longbottom, 32, from the Gloucestershire area, was injured on Friday on the site next to Uskmouth power station at Nash, Newport.
Gwent Police and the Health and Safety Executive have begun an investigation.
A spokeswoman for the power station said: "Our thoughts are with the family of the man who has died. It must be the most awful time for them".
South Wales Fire and Rescue said Mr Longbottom was extricated by fire and ambulance crews.
He was taken to the Royal Gwent Hospital, Newport, where he died shortly after.
His family have paid tribute to him.

"We are utterly devastated by the loss of our beautiful Christopher, the best husband, father, brother, friend and loving son," they said.
"We are so grateful for the time we had with him and mountains of love and laughter he gave us.
"Thank you for all the cards and everything which is bringing us comfort at this awful time."
Following his death, the power station said everything would be done to find out what happened, and to ensure that it did not happen again.
