Individual strengths.
A dynamic team.

It takes expertise in a broad array of fields if you want to switch the world to renewable energy. Our team at ToRa has all this expertise – plus the experience amassed in years of working in the industry. We act and plan as dynamically and flexibly as the decisions require, and we’re great believers in flat hierarchies and short lines of communication.

At ToRa, we’re not just about energy plants – we’re equally invested in people: colleagues, partners and services providers, landowners and neighbours, and all those responsible in administration and local authorities.
