(1888PressRelease) August 10, 2019 - Dowell is pleased to have been instrumental in the Hangzhou energy storage system project which has a capacity of 2MW/4MWh and has the distinction of being the first grid side energy storage installation in Zhejiang Province. It is located in the beautiful Yuhang District of Hangzhou City.

The installation is divided into two energy storage units, each with a capacity of 1MW/2MWh. The power station adopts a prefabricated warehouse design, which integrates electrical equipment such as the PCS, energy storage unit and control unit into the prefabricated warehouse. This design abandons the shortcomings of traditional power station construction, (large floor space and high investment), and opens up a new era for energy storage power stations. Using the flexible adjustment of power supply and demand, the ability to schedule and stability of grid operation are greatly improved. The smooth integration of the power station will provide nearly 4000kWh of electricity per day for users in the Yuhang Future Science and Technology City area, which can additionally require the electricity consumption of more than 400 households during peak hours.

The PCS500kW used in this project was designed by Dowell, a major player in the energy storage industry. In this hottest summer with temperatures so high and additional electricity required for air conditioning, the technicians worked overtime to ensure that the installation was ready as soon as possible and it was successfully put into operation on August 8.

This was a significant event for the province and was reported by local media.
