In their amendments to the Commission proposal, MEPs shortened the maximum period to approve new installations from twelve to nine months, if located in so-called "renewables acceleration areas". These will be marked out by each member state depending on whether they are able to install renewables at a faster pace. If the competent authority does not respond by the deadline, the permit or request is deemed to be approved - following the so-called “positive silence” principle. (Source: Euroepan Parliament)
