Sungrow builds first DC-coupled liquid-cooled energy storage project in Israel

Sungrow has announced that it has signed a 66MW/253MWh energy storage contract with Doral Renewable Energy Resources Group, an Israeli renewable energy and environmental infrastructure developer.

This is Israel’s first DC-coupled liquid-cooled energy storage project and will further improve the stability and reliability of Israel’s power grid as the market for photovoltaic (PV)-based plants grows.

As the Israeli government strives to achieve a 30% renewable energy share in total electricity generation by 2030, solar + storage solutions are becoming a trend to ensure the future of grid reliability and sustainability. Solar PV is expected to be the main contributor, accounting for 26% of this target.

Sungrow will provide the latest DC-coupled liquid-cooled energy storage system (ESS) solution for Doral Energy's solar + energy storage project. The 4-hour liquid-cooled ESS greatly reduces the capacity loss rate and significantly cuts capital and operating expenses due to its pre-assembled and easy-to-install design and more efficient battery working environment. At the same time, DC coupling simplifies the design and does not require an additional power conversion system (PCS) and medium voltage station, saving project costs.

Doral is an Israeli energy storage system (ESS) developer, with a total contract capacity of 1.44GWh for its Solar + Energy Storage I and II government tenders. Yaki Noyman, CEO of Doral Energy, said: "With Sungrow's solution, we finalized the procurement requirements for the PV Energy Storage 1 tender and took the first step in cooperating with Sungrow, enabling our global energy storage business to rely on key suppliers."

Roni Brandes, Doral's head of energy storage, projects and procurement, said: "Sungrow's DC-coupled design, as well as its liquid cooling technology, provided a competitive solution for the PV+storage tender, making the Dorals hybrid energy plant a landmark project for the entire region. We thank Sungrow for its dedication and expertise, as it provided a technical solution that made the initial investment lower while maximizing the potential for the project stakeholders."

“We are excited to be working with Doral Energy to provide DC-coupled liquid-cooled ESS solutions,” said Tzvi Ben David, General Manager of Sungrow Israel.

“We signed a 430MWh liquid-cooled energy storage supply contract with Enlight Energy at the end of 2021 and a 64MWh contract with Afcon in March. With the addition of the 253MWh agreement, Sungrow becomes one of Israel’s key energy storage solution providers, contributing to the local net zero goals,” he added.
