Sungrow and Delta Capacity sign pact for deploying 1 GWh BESS

Sungrow and Delta Capacity have signed a 1 GWh framework agreement for battery energy storage systems (BESS), further expanding their partnership in Europe’s rapidly growing energy storage market.

The agreement was signed at the Energy Storage Summit held in London. Under the deal, Sungrow will supply its PowerTitan 2.0 energy storage solution, with project deliveries and deployment scheduled within 2026.

The collaboration supports Delta Capacity’s strategy to build a diversified portfolio of utility-scale BESS assets across Europe, targeting long-term ownership and operation. The company is currently developing and acquiring storage projects across multiple regions, including Scandinavia, Germany, Southern Europe, and Central Europe, focusing on system efficiency, reliability, and safety across project development and operations.

Europe’s highest-quality BESS portfolios

Patrik Hes, Founder and CEO of Delta Capacity, said the company aims to build one of Europe’s highest-quality BESS portfolios spanning several markets while maintaining long-term ownership of the assets.

“Our ambition is to build one of Europe’s highest-quality BESS portfolios across several markets and operate these assets long term. This requires robust design, efficiency, and reliable partners capable of delivering projects at scale,” Hes said.

James Li, Vice President and Director of ESS at Sungrow Europe, said the framework agreement strengthens the collaboration between the two companies.

“This partnership combines Sungrow’s proven PowerTitan 2.0 technology with Delta Capacity’s project execution capabilities to deliver high-performance energy storage projects supporting Europe’s energy transition,” he said.

BESS Projects In Europe 

Founded in 2022 and headquartered in Switzerland, Delta Capacity develops, acquires, owns, and operates utility-scale battery storage projects across Europe. The company currently has nearly 800 MWh of projects under construction and aims to build and operate more than 6 GWh of storage assets by 2030. Among its key projects is a large battery storage development in Ånge, Sweden, considered one of the largest projects currently under development in the Nordics.

Sungrow will supply its liquid-cooled PowerTitan 2.0 system, designed to reduce both capital and operational expenditure through its integrated AC-DC block architecture. The system features pre-assembled battery modules and power conversion systems, enabling faster installation and improved operational efficiency. The technology also allows projects to participate in grid balancing, ancillary services, and energy trading markets.

Sungrow has deployed several large-scale storage projects in Europe, including an 800 MWh BESS project in Belgium and the 330 MWh Bramley energy storage project in the United Kingdom.

Globally, Sungrow has installed over 1,000 GW of power electronic converters, with its solutions deployed across renewable energy projects worldwide.
