What they do
Isotrol specialises in developing enterprise software for the renewable energy industry, focusing on monitoring, control, optimisation and trading of renewable assets without directly owning or developing generation projects (source: isotrol.com).

Bluence is deployed in photovoltaic solar, wind and other renewable installations, and the company also develops cloud and SaaS solutions with artificial intelligence and advanced analytics, such as the TALOS and XSIM projects to improve fault detection and energy efficiency (source: isotrol.com). Its clients include utilities, independent producers, renewable asset operators, energy traders and large energy companies, highlighting its unique integration of operational technology, energy engineering and proprietary software to provide end-to-end solutions from plant control to fleet and market management (source: elmundo.es).
