The GenCell REX™ utility backup power solution produces 5kW of auxiliary electricity for substations during outages of any duration. It operates as a direct source of backup power or supplements legacy backup battery systems that can provide only 6-8 hours of electricity.
The Power Challenge
Aging electrical grids and more frequent extreme weather make it increasingly challenging to meet the power resilience needs of always-connected businesses and consumer lifestyles. In 2015, Americans experienced a reported 3,571 total outages, with an average duration of 49 minutes. Momentary blackouts cost the US economy $60 billion while sustained blackouts cost $50 billion.
GenCell REX : the subsatation backup power solution with the X factor-eXtended runtime
Powered by hydrogen, the GenCell REX utility Backup power solution produces 5kw of emission-free electricity for subsations during power outages. Operating as a direct source of power or supplementing legacy backup battery systems that provide only 6-8 hours of electricity, the GenCell REX keeps circuit breaker auto-reclosers operational until the grid recovers. The solution alleviates the need for costly multiple battery rooms, avoids the pollution and maintenance costs of diesel and includes a shelter that is resistant to high-voltage interference and earthquakes.
The GenCell REX is an enhanced version of the GenCell G5rx solution, available in three configurations – 130VDC, 48 VDC and dual 130/48 VDC output in a single unit to support both substation loads and communications systems. The GenCell REX also offers enhanced integration with leading utility SCAD systems and improved remote monitoring and control software.
