Our take
The energy landscape is one of the most dynamic and fast-evolving sectors in the world. More and more energy retailers are looking to move further toward digitisation and reap the benefits of modern technology in an increasingly connected world. But many are struggling with the transition, held back by legacy operating systems which slow them down, drain resources, and hamper innovation.
This is where Kaluza comes in. An ecosystem of platforms whose services range from energy billing to smart electric vehicle charging, Its real-time cloud platforms transform supplier operations, reducing the cost to serve and boosting customer engagement. Essentially, its platform is aimed at helping businesses streamline their operations, saving them time, effort, and money which can be better invested elsewhere.
Kaluza is riding the momentum of a growing desire for sustainable business and services. Its program relating to electric car charging, for example, will be able to capitalise on huge new demand in that sector - over 100,000 electric cars are already on the roads in the UK, and Bloomberg New Energy Finance has predicted that electric cars will account for over 50% of new global car sales by 2040. As the globe moves further towards sustainable use of energy in the coming years, Kaluza could be very well positioned to capitalise.
