‌Looking ahead to 2040: building tomorrow's transition today

THE GREEN TRANSITION IN EUROPE IS CURRENTLY FACING A PERIOD OF UNCERTAINTY DUE TO:

  • Political and economic scenario

  • Financial uncertainties

  • Slowdown in infrastructure development

  • Delay in the industrialization of key

    technological innovations

  • Inconsistency between regulatory and economic constraints to renewable energy development and the plans

    for energy independence and critical

    raw materials

  • Reduced transparency and clarity regarding regulatory constraints

‌Ambitious goals, built on our strenghts




Among the leading national players in integrated water services and electricity distribution





The only operator in Italy to have put forward an advanced public-private partnership proposal for the renewal of hydroelectric concessions

Extension of the district heating network to fully utilize plants capacity

We are closing the urban waste cycle by developing 3 new Waste-to-Energy (WTE) plants

With a renewed portfolio of products and services, an excellent customer base, and a widespread territorial presence, we will become the main point of reference for our customers
