To support sustainable energy behaviour, ECOHZ helps customers consume renewable energy and create new renewable energy. We dedicate our deep knowledge and can-do attitude to helping our customers change their energy behaviour. ECOHZ chooses, implements and documents customers’ energy behaviour.

ECOHZ offers global renewable energy solutions to businesses, organisations and electricity providers – providing renewable electricity, from a wide range of sources, regions and qualities. Renewable electricity is documented by Guarantees of Origin in Europe, RECs in North America and International RECs (I-RECs) in a growing number of countries in Asia, Latin America and Africa. ECOHZ also provides an innovative additionality solution – GO² – combining renewable energy purchases with the financing and building of new renewable power generation. Companies choosing documented renewable energy can reduce their carbon footprint and improve their sustainability ratings. ECOHZ is among the leading independent suppliers in Europe, and has offices in Norway and Switzerland. ECOHZ endeavours to play an active role in the current energy transition through its vision of “changing energy behaviour”.

Large portfolio

In 2018, ECOHZ managed a renewable energy portfolio of more than 50 TWh, making the company one of Europe’s largest independent suppliers.

ECOHZ’s portfolio includes Guarantees of Origin from more than 200 power plants, based on fixed supplier agreements with over 20 power producers. The portfolio comprises renewable electricity generated from hydropower, wind power, bioenergy, solar power and geothermal energy.


The company Enviro Energi was established in 2002 by Leif Hegna and John Ravlo, with support from nine Norwegian power companies. From the start, the business concept was to be a European provider of Guarantees of Origin and value-added services for renewable energy. In 2007, Home Capital AS acquired a majority stake and the company’s name was changed to ECOHZ. ECOHZ currently has 18 employees.
