Values & Responsibility

ATN takes energy efficiency seriously at its head office in Oppach
Quite apart from its involvement in the network, ATN is a long-standing proponent of energy efficiency. Since 2008, most of the company’s power and hot water requirements have been supplied by combined heat and power (CHP) plants that were built in conjunction with ATN’s premises in Oppach. And when it was time for the first site expansion, we added a large solar installation to the roof. The construction of the third hall will boost these capabilities yet again, totalling 630 kWp from solar panels.
ATN's long-term corporate goals include a responsible approach to the environment and resources as well as investing in modern technologies to protect the climate.
