We have a team of lawyers and paralegal-administrative support: always open to receive new talent to strengthen our firm with professionals who share our mission.
Proximity to the customer and making ourselves understood is crucial for us. That is why in our team we work in different languages English, Spanish, Catalan, German, Dutch, French and Italian.
We are members of different sectoral organizations such as APPA (wind, photovoltaic, and self-consumption sections), AEDIVE, SECARTYS, SOLARTYS, AEPIBAL the CEEC, UNEF, AEMENER and AEH2. We actively participate in the working groups of most of these sectoral associations. Piet Holtrop is a regular speaker at many of the conferences organised by these entities.


Our clients are mainly companies and public administrations.
