EDP has just completed the installation of the first denitrification unit in Spain at the Aboño Thermal Plant. At the same time, the construction of a similar facility at Group 3 of the Soto de Ribera Thermal Power Station is underway, and will be completed in the first months of the coming year.
The entering into operations of these units in the two EDP plants in Asturias equips them with the best available technology for emission control and extends their useful life to at least December 2030.
The value of EDP's current investment in the construction of these facilities in Spain is 90 million euros, a result of the decision to provide these groups with the best available technology, contemplating the transposition of the European Union Environmental Emissions Directive 2010/75 to Spain.
On completion of this project, EDP will have invested over €200 million in the last decade in environmental improvements to its power plants in Asturias. This level of investment along with the efficiency of the maintenance and operation of its production groups makes EDP plants the most efficient in the country.
 

These environmental investments have been made in the Sines Power Plant in Portugal between 2008 and 2011 with a total investment amount of 326 million euros as a result of EDP Group's strategic commitment to reducing the effects of greenhouse gas emissions.
With 1180MW of installed capacity, Sines is currently one of the most efficient plants on the Iberian Peninsula, playing a key role in the country's supply security, particularly in years of low water and wind production such as 2015.
Thermal power plants increasingly play an indispensable backup role in electrical systems with strong elements of intermittent renewable sources, such as are the cases of Portugal and Spain, with coal playing a leading role in relation to natural gas as a result of the European market prices of CO2 licenses and consequent lower costs of production. The competitiveness of Sines has allowed maximization of production capacity in the market.
EDP already has 70% of its production capacity based on renewable energy.
