Story of Ongresso Energy.

Our team is committed to the overall goal of reducing the carbon footprint. Our concrete actions include the implementation of new renewable energy sources and/or energy efficiency, we help to make sustainable projects feasible by transferring mitigation results (carbon credits). This motivates us to go the extra mile.


Ulrich Hinterberger and Daniel Breitenmoser founded Ongresso, a one-stop-shop for market expansion into Latin America. Ongresso’s value proposition is to reduce time, costs and risks to establish and operate investments and businesses in Latin America. As a company with a Swiss Head office, Ongresso meanwhile counts with subsidiaries in Colombia, Peru and Mexico.


Ongresso Energy is created as a brand within the Ongresso organization. OE and Nvest join forces to execute a mandate from Norsk Solar for development of solar C&I projects in Colombia. Both companies also obtained various other mandates for the sourcing of investment for social and environmental impact projects.


Ongresso Energy obtains a mandate from the Swiss Federal Office of the Environment (FOEN) and the Peruvian Ministry for the Environment (MINAM) to develop and implement with the Additional Renewable Energy Platform Peru (AREP Peru) one of the first bilateral carbon offsetting programs in accordance with Art. 6 of the Paris Agreement.


Ulrich and Daniel founded Ongresso Energy AG (OE AG), a Swiss limited liability company together with entrepreneur Thomas Stetter.

Ongresso Energy SAS (OE SAS) is co-founded in Colombia by Niels van der Wijk and Nelson Camacho. OE SAS is the local project development and management company of OE AG.

All forces are now consolidated to be an Independent Power Producer (IPP) and development service provider.
