The Fiume Santo thermoelectric plant extends over around 152 hectares in the Gulf of Asinara, at “Cabu Aspru”, in the province of Sassari. With net installed power of around 600 MW, it is one of the most important power plants in north-west Sardinia.

At the plant there are currently two coal-fired units operating, each with a nominal power of 320 MW. The two units that were powered by oil came into operation in 1983-84, each with nominal power of 160 MW, and were permanently shut down on 31/12/2013 and are currently being disposed of.

Protecting the environment, health and safety

The power plant is equipped with highly advanced environmental systems that can reduce the polluting elements present in the fumes. Units 3 and 4 have systems to reduce sulphur (DeSOx) and nitric oxides (DeNOx), and systems to reduce particulates (PE). Thanks to these systems, atmospheric emissions comply with the limits set by legal provisions.

Since 1983 there has been in operation a network to monitor the air quality in order to check for the ground-level effects of the main pollutants (sulphur oxides, nitric oxides and particulates).

The plant is equipped with an Environmental Management System and since 2005 has been registered on the EMAS European Register under number I-000403.

Protecting the health and safety of workers and of working environments is a key issue for the company. Since 2009 the plant has adopted a Safety Management System which is certified in accordance with BS OHSAS 18001 with which the company pursues the goals of continuous improvement in the safety performance of plants, employees and contractors. Since December 2011 the plant has been notified as a building at Risk of Serious Incident and applies a Safety Management System to prevent incidents in accordance with the provisions established in the policy document.

In addition, the plant is ISO 9001 certified for unloading from coal ships, the burning and production of fly ash obtained through the combustion of coal dust and virgin biomass, classified, in compliance with EU Regulation No. 305/2011 of the European Parliament and Council, as a quality product and used as construction material under certificate CE 0099/CPR/A95/0014.

Since May 2010 the Fiume Santo plant has had, with Decree DVA-DEC-0000207 of 26 April 2010, integrated environmental authorisation to operate the plant.
