GDF Suez Poland says it will demand compensation if Poland introduces a new renewables law cutting support for green energy.
Chief Executive of GDF's Polish unit Grzegorz Gorski issued the warning this week.
The French company is most concerned about plans to cut support for biomass co-firing, the largest source of renewable power in Poland's energy mix.
"The rules proposed for biomass co-firing, which is key for us, are significantly worse than those in the currently applicable energy law," Gorski was quoted as saying by business daily Puls Biznesu.
"(If the new law is enacted) we will go to arbitration and demand several hundred million zlotys from the state."
In July, Poland's economy ministry proposed a draft bill that reduced overall state support for renewable energy, favoring solar power and offshore wind over biomass co-firing and onshore wind.
