Antas delivers optimized energy supply solutions for the public sector in Italy. It was founded by Italian entrepreneur Sergio Giglio in 2006 and has since expanded to employ approximately 300 people in Italy.


  • Antas has acquired Energy Wave, a leading energy supply contracting solutions provider for large residential buildings with centralized heating systems in North Western Italy, from Ambienta, Europe’s largest sustainability focused investment fund
  • Energy Wave was established in June 2018 as a spin-off of the energy services business of Restiani. Following the spin-off, under its new CEO, Stefano Granella, Energy Wave broadened its solutions offering to include new value-add services such as thermal insulation, LED relighting, photovoltaic systems, heat pumps, and micro cogeneration
  • Energy Wave represents a unique opportunity to complement Antas’ public offering capabilities with a private market platform, and allows it to generate additional growth in the Italian ESCO market

Greentech Capital Advisors acted as exclusive financial advisor to Antas. The transaction further strengthens Greentech’s leading advisory position in energy technology and services.

Giovanni Pontrelli, CEO of Antas, commented “The combination of Energy Wave with Antas creates an Italian ESCO champion. We are excited about the unique opportunities this combination will create for our clients, employees, and shareholders.”
