Iberdrola's legal challenge tests who can say no to solar in Italy

In a ruling published on 1 October, Italy’s Constitutional Court upheld a national ban on ground-mounted solar on farmland and left Sardinia’s law on where renewable plants may go untouched. Sardinia’s government says the judgment vindicates its approach, since its maps of suitable and unsuitable land remain in force. For developers bidding for contracts in Italy’s new renewables auctions, the better question is whether a region’s map can still delay, burden or block a project, and which of those powers now sits with the state.
