The total investment is €78 million, of which "€56 million were was spent between 2016 and 2018", the company said, estimating that, by the end of this year, "more than 20% of the street lights in mainland Portugal will be LED ", contributing to a reduction in the ecological footprint (by 40,300 tons per year) and a reduction in electricity consumption (by 80.1 million kWh/year).

The 278 Portuguese municipalities are expected to save €16 in 2019 and following years, EDP Distribuição said.

The campaign aims to "replace obsolete mercury vapour and high pressure sodium vapour technology street lights LED, through the installation of multi-service public lighting posts and a new system of remote management of lights that provides conditions of visual comfort, safety of people and goods, and reduced maintenance needs, in an increasingly sustainable way".

According to EDP Distribuição, this campaign is part of the company's strategy of "modernising the distribution network and adopting new technologies, essential to the energy transition and decarbonisation, in line with the National Energy and Climate Plan".
