Ultra Rapid EV Charging Battery (Chargefox)

Ultra Rapid EV-charging station in Goulburn, NSW.

PowerTec has delivered the first of a fleet of EV-charging station batteries for the public EV-charging network, Chargefox. The 250kVA / 270kWh PowerCache® delivers benefits for the owner (Chargefox), the energy company (Hydro Tasmania), the network, and the site operator (Goulburn Budget Petrol Station) – all at once! It primarily serves as an EV-charging buffer, allowing for ultra-fast charging despite a weak grid connection. Further benefits include electricity markets services (incl. FCAS), and site back-up power (including islanding as a microgrid), as well as network support.

Pole-mounted Community Battery (United Energy)

Pole-mounted PowerCache in a south Melbourne suburb

PowerTec, in an Australian first, has delivered the first of two prototype Pole-mounted Grid Battery Energy Storage Systems (BESS) in the suburb of Highett, Bayside area, Melbourne. The PowerCache® BESS enables the Distribution Network and the Energy Companies to serve the community with more flexible and economical ways to use solar energy. PowerTec is has worked closely with United Energy to deploy our PowerCache® technology as the pilot for this alternative way to deliver power distribution flexibility.
System details: The 30kVA/85hWh BESS operates mid-circuit of a 50-75 consumer LV feeder and provides voltage control, phase-balancing, load/generation peak lopping and smart time-of use solar energy shifting. Its most frequent use case, in the absence of any technical constraints on the network, is participation in Electricity Market Services, controlled by an energy company.
