Pacifico Energy Partners GmbH at a glance.

Pacifico was founded in 2016 by Ulf Oesterlin and Fabian Herberg as an investment company for operating renewable energy assets, with in-house asset management and development capabilities.

At the same time, we re-focused with the objective to maximize our contribution to the energy transition by pivoting into the development of new renewable energy projects.
