Portacell is a new type of electricity service for large off-grid construction sites which is completely carbon and emissions free. It’s the closest thing to a grid connection, but cheaper, easier and more flexible. We use a seamless supply of advanced ultra-HD batteries to deliver energy from certified renewables. Each HD unit is monitored and replaced by us with absolutely no supply interruption – ever. Even the transport is net zero. #actnow on air quality and global warming, with no compromise on operational reliability.
