EV Charging Demand Support

What is EV Charging Demand Support?

TROES is launching the “EV Charging Station Initiative” to provide turnkey solutions integrating its distributed energy storage systems with high power charging outlets and solar panels to meet the increased energy demands and to save on energy costs.

TROES welcomes collaboration with all interested parties with project ideas and opportunities in our bid to accelerate the adoption of innovative, cost effective and sustainable EV charging infrastructure.

EV Charging Use Case Example


EV Charger


Condominium buildings


As Condominium buildings face the new challenge of supplying power to the EVs of the residents of the building. High cost for demand charge especially when it comes with EV charger.


A 120kWh/100kW system will be used for peak shifting during peak hours, and 160kWh/80kW system used for EV charger. Condominium can purchase cheap power from the grid, store it, and sell it to those wishing to charge their EVs. 

As an example, assume that a condominium installs 10 EV charging stations, each of them rated at 8kW. The additional peak power demand that would result from all the EVs being in use during the same time is 80kW. In order to avoid additional Demand Charges from EV use during the 7pm-8pm building peak, the BESS extra capacity required to fully cover the EVs is 160kWh/80kW. Our typical use expectation is that the EV chargers will each be used for about 5 hours per day, resulting in 80kW from 6pm to 10 pm and the energy consumption could be 400kWh per day. 

Assuming the EV charger usage fee is around $1.45/hour, and the energy selling price of $0.182/kWh (Reference Price).

Use case example for EV Charging
The operating revenue from the EV charger is $25,540 per year. Given an approximate initial investment of about $106,000, equating to 50 months (4.1 years) to recapture the capital invested. This period may be extended if the project is funded with debt, in which case the interest rate will drive the payback period.
