There is a project of constructing a gas pipeline from Guarda to Bragança, supported by the European Comission as an european project.
This is simply a highway to gas, nothing comes out for the local populations except of leaks or accidents. The gas pipeline passes by the Douro Vinhateiro and at this moment the route suggested by the company (REN) has been refused of crossing the world heritage. REN is considering some little changes in the route to get the license.
