Energy consumption is an environmental aspect that is assessed and measured at all Ansaldo STS offices and production sites when the environmental aspects of work sites and the construction of civil and technological works are analyzed.

To meet its production and operating requirements in 2016, the group consumed a total17 of 121,929.5 GJ of energy. Compared to 2015, total consumption dropped by of 2,325 GJ (-1.9%), and this concerned both the production sites for 1,413 GJ (-4.3%) and the office sites for 912 GJ (-1.0%).

The consumption analysis in absolute value by energy source compared to 2015 reveals:

  • an Electrical Energy consumption reduction of 475 GJ (-0.6%) as the consequence of the 1,732 GJ decrease (-6.0%) recorded at the production sites and of the 1,257.3 increase (+2.2%) at the office sites, 37% of which is due to including the Spanish sites in the scope of the report;
  • a reduction of Natural Gas consumption of 1,769 GJ (-6.6%), mainly due to its decrease recorded at the office sites (-8.4%);
  • a reduction of Diesel consumption of 807 GJ (-11.2%), also in this case due to its decrease recorded at the office sites (-995.6 GJ, equal to -13.9%);
  • a reduction of Petrol and LPG consumption for haulage of 220 GJ (-8.5%);
  • an increase in district heating use of 946.4 GJ (+39.1%).

In 2016, the Energy intensity performance indicator showed a substantial reduction at production sites (-10.7%) due to the combined effect of the increase in hours worked (+7.2%) and the decrease in consumption (-4.3%). The indicator increased slightly (+1.8%) at the office sites. Both consumption (-1.0%) and hours worked (-2.7%) were down.

Renewable energies

Ansaldo STS again acquired electrical energy consumption certificates for its Italian sites under the Renewable Energy Certificate System (RECS) in 2016. These certificates represent 1 MWh, and attest to the use of energy from renewable sources, which include, as defined by EU directive no. 2009/28: wind, solar, aerothermal, geothermal, ocean, hydraulic, waste-to-energy, landfill gas, residual gas from purification processes and biogas.

Since 2014, the Solna site has adopted an energy source mix that is totally renewable (wind power, hydro-electric and waste-to-energy).
