The National Data Centre Plan (PNCD) is the strategic public policy instrument that defines the State’s action to create the conditions needed for the sustainable and competitive development of the data centre sector in Portugal. Based on the recognition that these infrastructures are essential for the digitalisation of the economy, for attracting investment, and for strengthening digital sovereignty, the Plan seeks to address the main constraints limiting the sector’s growth, such as regulatory complexity, institutional fragmentation, and the country’s insufficient attractiveness compared with other markets.
