Concerns have been raised by environmental experts regarding a possible increase in the number of pylons needed when new wind farms are constructed.
According to the Campaign for the Protection of Rural Wales, hundreds of the metal towers will need to be built to cope with rising energy demand.
President Glyn Davies said: "It is clear that, in addition to the blight caused by the wind farms themselves, there is now a need for hundreds of 80 metre high pylons to carry the electricity from these upland sites through our valleys, to connect these wind farms to the National Grid."
He added that the group had been opposed to the building of so many wind farms in Wales because of the visual impact they will have.
A spokeswoman from the National Grid said, however, that it was unclear how many more pylons would be needed in Wales to cope with the extra electricity generated by wind.
Earlier this week, a report claimed that in order to generate just one sixth of the UK's energy needs, wind turbines would need to be built on a land area the size of Wales.
