I bring you some fresh news directly from China that will impress you. In June 2024, China took a giant step forward in the field of renewable energy by completing the world's first large-scale semi-solid-state BESS (Battery Energy Storage System) power plant, located in Zhejiang.

The power plant, developed by Kehua, has an energy storage system with 100 megawatts and 200 megawatt-hours, using lithium-iron-phosphate (LFP) batteries. This project is not only large in scale, but also in innovation. Semi-solid-state batteries offer greater safety and reliability, which are essential for the stability of the power grid in eastern China.

The secret to success lies in the integration of semi-solid batteries with high-performance converters. Kehua deployed 1,25 megawatt converters connected in parallel through a 5.000 KVA transformer, resulting in a grid-connected output of 35 KVA. This guarantees incredible energy efficiency and system stability that is being highly praised.

Environmental benefits of China's first semi-solid state power plant

Besides all this technological innovation, the power plant has a huge positive impact on the environment. At full capacity, the plant can store 200.000 kilowatt-hours of electricity and has an annual discharge capacity in excess of 60 million kilowatt-hours.

This translates into a saving of approximately 23.000 tonnes of standard coal and a reduction of around 72.000 tonnes of carbon dioxide emissions per year. It's too much!

The BESS power plant plays a key role in balancing energy supply and demand, supporting local energy transformation initiatives. By smoothing load peaks and optimizing grid utilization, it helps make the power system more efficient and reliable.

Kehua: technology leader

With over 36 years of experience in power electronics technology, Kehua has established itself as a global leader in photovoltaic installations and energy storage solutions. By 2023, the company had deployed more than 46 gigawatts of PV installations and 15,2 gigawatts of energy storage facilities worldwide. Not bad, huh?

Kehua's commitment to clean energy solutions and sustainable innovation remains strong. The company is determined to lead the transition to a greener and more sustainable energy future, leveraging PV and energy storage technologies to promote a zero-carbon lifestyle.
