The SEA Group at both airports has cogeneration/ 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.

An extensive analysis of energy consumption in the 2010-2012 period highlights a reduction in electricity consumption.

SEA Energia

SEA Energia manages the cogeneration stations at the Malpensa and Linate airports, satisfying all the energy requirements of Malpensa through its tri-generation plant which since 1998 have ensured the selfsufficiency 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 trigeneration 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 2012 the thermal and electric energy production activities continued to satisfy the needs of the airport system and sale to third parties. During 2012 the production of electricity reduced by 13% (-65.6 million kWh).

In 2012 the production of electricity by SEA Energia decreased by 13.7% at Malpensa and by 10.0% at Linate compared to 2011, amounting to a total of 449.2 million kWh (-65.6), with a consequent reduction in electricity sold of 19.1% at Malpensa and 10.4% at Linate compared to 2011, amounting to a total of 416.7 million kWh (-84.8).

In 2012 the production of thermal energy by SEA Energia increased by 2% (+7.1 million kWh) compared to the previous year, amounting to 332.7 million kWh.

The Linate Station received green certificates issued by the Energy Service Operator (GSE), valid for 8 years from issue.

In 2012 the electricity supply contracts to Bergamo Orio al Serio airport (13.4 million kWh), to the Sheraton Hotel at Malpensa and to the Rome Airports continued. In 2012, the tender was awarded for the supply of electricity to Gesac which manages the Naples airport.
