Grid-connected ESS

ESS Success Case

200MW +

These fields of energy storage system are under construction or already completed, specializing in heavy electricity users, TPC energy trading platform, and solar plus ESS solutions.

Billion Watts has established long-term partnerships with well-known domestic manufacturers to build a domestic one-stop renewable Energy as a Service (EaaS) company, providing energy storage battery container, Battery Management System (BMS), Power Conversion System (PCS) , and Energy Management System (EMS), which have passed relevant Taipower company communication and capability tests. We can provide diverse energy storage solution such as：grid-connected energy storage, large power consumers and behind-the-meter energy storage, and photovoltaic combined energy storage, according to different application scenarios. 


We are the first domestic manufacturer that aggregates grid-connected energy storage resources and bids for Regulation and Frequency Response Service. We have teamed up with well-known large-scale renewable energy investors at home and abroad. The construction will be completed in the second half of 2022, of which 200MW has already been opened for civil works.
