No emissions, no carbon and no compromise

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.

How it works

An illustration showing the first stage of the Power-as-a-Service process, showing three Portacell battery units being charged by renewable electricity.

Portacell units are charged from REGO-certified renewable energy

An illustration showing the second stage of the Power-as-a-Service process, showing a Portacell battery unit being transported to site on a zero-emission vehicle

Zero-emission vehicles deliver the units to site

An illustration showing the third stage of the Power-as-a-Service process, showing a depleted Portacell battery unit being replaced by a fully-charged one

We install the fully-charged units on site or exchange depleted ones

Power as a service

What is Power-as-a-Service?

PaaS is the name we give to our innovative delivery model. It means you only pay a service charge and the cost of the actual energy you use at the rate you use it. And you leave the rest to us.

Say goodbye to demand predictions and load-matching because Portacell’s one-size-fits-all service is totally flexible.

Just draw the energy at the rate you want, for as long as you want, when you want it.

There is no charging or changeover downtime. Continuous supply is guaranteed.
