A Jimmy generator operates with a micro-nuclear reactor based on the HTR (High Temperature Reactor) technology. This technology has existed since the 1960s and is in operation in several countries.

A Jimmy generator provides heat at a competitive price compared to other heat sources, with secure supply and price predictability over 20 years.

A Jimmy generator is installed, operated, and decommissioned by Jimmy. Depending on the industrial site's needs and consumption, one or more generators can be combined to deliver the required power.

A Jimmy generator produces heat without emitting CO₂ and helps save nearly 40,000 tons of CO₂ equivalent per year.
