About the Company

trawa

Berlin, Germany

Welcome to the trawa universe! Our mission is to make high-quality and affordable green electricity accessible to companies of all sizes! As a full-service provider for the optimized purchase of green electricity, we support small and medium-sized companies in procuring their electricity in the same way that large corporations can: sustainably and at the same time cost-effectively. To do this, we have developed an AI-based technology that analyzes our customers' electricity consumption and creates transparency about the current costs and CO₂ emissions. The analysis enables us to put together the optimal electricity portfolio from renewable energies for our customers that really suits their consumption behavior. We purchase the electricity products on the market and thus also give medium-sized companies access to renewable energies - such as solar and wind PPAs. Our goal is to professionalize energy procurement and counteract climate change through renewable energies. Together with our partners and customers, we work every day to reduce the CO₂ footprint of German companies.
