TECHNICAL AND FINANCIAL COMPARISON

 

 


ENERGIESTRO is an economical solution. Its initial cost is moderate because it makes use of technologies from the automotive industry. Its operating cost is low thanks to its high efficiency.
The innovation resides in the integration of a high efficiency kinetic energy storage with a cogeneration system.
This energy storage enables the ENERGIESTRO set to operate independently from the grid, controlled by power demand, which makes it radically different from other cogeneration systems, controlled by thermal demand and unable to operate without the grid.
