Compare Fleets

The rise in EVs challenges companies to make the most of their fleet and charging infra investments.

Comparing different scenarios, vehicles, chargers, and business models for EV charging infrastructure and EVs is unnecessarily time-consuming and cumbersome.

Compare Fleets allows you to investigate and optimize the financial returns with granular details, easily compare total cost of ownership for EV and ICE vehicles and sell your charging solution with confidence.


Timeseries Energy

As renewable energy projects are becoming more hybrid, there is a lack of high-quality data that reflects real world performance.

Engineering teams are missing out on high-frequency energy data based simulations with high accuracy for rapid decision-making and more profitable investments.

Timeseries Energy allows accurate planning of hybrid RE assets with high-frequency data based energy calculations. For operational assets, Timeseries enables better forecasting and scheduling.
