The French company Cegelec is to send a top official from Paris to French Polynesia in a bid to negotiate a solution to a protracted stand-off involving staff at its Papeete affiliate.
Workers at the Tahiti branch have been in strike in protest at planned dismissals.
The territorial government has received union representatives who want government support to stop any sackings.
Earlier this week, Cegelec workers blocked the access to the Papeete port but lifted the blockade after warnings that riot police would clear the access.
The strike comes amid other industrial action of construction workers at the site of the new hospital, petrol company employees and staff of a phone company.
Municipal workers in one town are also on strike.
