In 2017, total energy consumption - electricity, methane, diesel, LPG and district heating - amounted to 119,971 GJ, down 1.6% compared to 2016 despite an overall 4.7% increase in hours worked. In the three-year period 2015-2017, overall consumption fell by 3.5%.

The Energy intensity performance indicator showed a reduction of 5.8% in the 2016-2017 period due to the combined effect of the increase in hours worked (+4.7%) and the decrease in consumption (-1.6%).

Renewable energies

Once again, in 2017 Ansaldo STS requested the cancellation of its GO certificates (Guarantee of Origin), an electronic certification attesting the renewable origin of the sources used, for the Italian sites and offices.

By acquiring and subsequently cancelling the certificates (the latter entails the withdrawal of the certificate from the market), Ansaldo STS demonstrates its commitment to environmental sustainability through its willingness to pay the positive difference with the price of electricity from conventional sources.

In addition, the Solna site uses a mix of totally renewable energy (wind, water and biomass).
