GridJet

GridJet Oy provides inspection services for energy and water infrastructure. For district heating networks it uses a high-resolution FLIR thermal camera with special optics to locate leaks and insulation damage. For electricity networks it runs aerial inspections, with fault observations recorded during the flight and, in urgent cases, sent in real time from a helicopter to a control centre. It also offers laser scanning of power line corridors to plan vegetation clearing and to inspect network components.

Customers include electricity and district heating network operators, the ELY Centres, water utilities, engineering consultancies doing groundwater studies, and geologists. Groundwater services use thermal mapping to find areas where groundwater lies near the surface, including discharges into lakes and rivers. Clients receive a report of the findings, such as temperature anomalies and their locations on the network, or a vegetation and component condition report.

GridJet was founded in 2014 and is registered in Valkeala, Finland. It also lists a postal address in Kouvola.
