The management of SEA Group energy consumption is based on the following principles: 

  • energy must be produced in respect and protection of the environment;
  • the reduction of the environmental impact and the improvement of the environmental specifications fall within the criteria utilised for the definition of company strategies, also in terms of infrastructural development;
  • the awareness of all (employees, partners, suppliers, contractors) on the environmental impacts of their activities is a central concern for the improvement of the environmental performance at both airports. 

Energy efficiency actions

The SEA Group at both airports has co-generation/tri-generation stations in operation which generate on an ongoing basis energy savings benefitting the SEA Group, the quality of the environment and the inhabitants of neighbouring areas. The SEA Group offers high efficiency services which allow the generation of savings both for the Company and for clients which, thanks to the use of district heating, achieve savings from heat recovery.

The policy of energy saving investments implemented in recent years has produced important impacts on consumption. The growth in absolute terms of electricity in 2013 at Malpensa airport is due to the opening of the third satellite at the airport.

SEA Energia

In 1992, SEA incorporated together with other industrial partners, SEA Energia SpA, with a corporate scope focused on the construction and management of energy production plant.

SEA Energia, now entirely controlled by SEA, designs, constructs and manages co-generation plant for the supply, production and sale of electric, thermal and cooling energy. The company manages the co-generation stations at the Malpensa and Linate airports. SEA Energia satisfies all the energy requirements of Malpensa through its tri-generation plant which since 1998 have ensured the self-sufficiency of the airport from external electricity, heat and cooling through an improved combustion yield compared to large thermal electric stations and an optimisation of smoke and heat otherwise lost. The network is only utilised for the emergency electricity reserve.

The station is also noted for its high capacity and is one of the largest in Europe. The positive tri-generation experience at Malpensa resulted in the company introducing the project also to Linate, where the heat produced will be used for the provision of district heating to an extensive urban area (Milan-East). The two plants are the first combined cycle co-generation plant at Italian airports and have assisted SEA in achieving significant consumption savings through precise temperature control at the various terminal rooms and offices and for all lighting consumption. In 2013 the thermal and electric energy production activities continued to satisfy the needs of the airport system and sale to third parties. During 2013 the production of electricity reduced by 16% (-72 million kWh).

SEA Energia's electricity production in 2014 reported a 19.3% decrease on Malpensa and 16.4% on Linate compared to 2013 and stood at a total of 307.5 million KWh (-69.7 million KWh) with a consequent drop in the electricity sold which posted a 19.5% decrease on Malpensa and 18.0% on Linate compared too 2013, and stood at a total of 295.9 million kWh (-69.7 million kWh).

SEA Energia's production and sale of thermal energy reported a 7.3% decrease for Malpensa (-19.6 million kWh) and 10.1% on Linate (-7.5 million kWh) compared to the previous year and stood at a total of 317.7 million kWh (-27.1 million kWh).

This decrease was the result of the mild weather conditions of 2014 marked by higher than average temperatures compared to previous years.

White Certificates

The characteristics of the Malpensa technological station satisfy the requirements for the recognition by the Energy Service Operator of white certificates to economically support high yield co-generation units. For the co-generation production of the Malpensa station in 2014, 6,504 white certificates were requested from the energy service operator, of which 4,375 concerning combined cycle 1 (CC1) and 2,129 for combined cycle 2 (CC2).
