European BESS: 105 MWh for Greece, 65 MWh for Switzerland

Sungrow and KTISTOR Energy have teamed up on several small BESS projects in Greece, amounting to a total capacity of 105 MWh. The projects will deploy Sungrow’s PowerTitan 2.0 liquid-cooled BESS which was designed specifically for grid-forming applications. Its smart AC-DC block architecture enables fast deployment and adaptation to projects of different sizes.

The companies aim to deliver the BESS by the summer of 2025, and this will be the first time Sungrow’s PowerTitan 2.0 will be used in the Greek market. The projects are located in central and northern Greece. Two will operate under the Greek ESS Tender scheme, while the other two will participate in the free market.

The Dokos project in Rodopi, with a license of just over 8 MW for two hours, will offer an initial installed usable capacity of 25.065 MWh.

The Petra project in Kozani has been licensed for 7.8 MW for two hours to provide just over 20 MWh.

The other two projects, Agia Anna and Agia Anna II, will be located in Viota. Both are licensed for 7.8 MW for three hours with an initial installed usable capacity of just over 30 MWh.

Renewables construction company KTISTOR Energy will take on engineering, procurement and construction duties for each project.

These announcements come at a time when the Greek BESS market has suffered a setback. The country cancelled its third standalone battery auction recently after its regulator found there was no unified understanding among bidders regarding the rule on the maximum power limit per participant.

German energy storage provider Intilion has agreed to build a stand-alone BESS of around 65 MWh for Swiss company Primeo Energie. Construction is expected to begin in spring 2025. When it is completed, it will be one of the largest BESS in Switzerland.

According to Jan Baumann, Project Manager Energy & Grid Management at Primeo Energie, the system “will be used to compensate for weather-related fluctuations in the area’s rapidly growing renewable electricity production. It will, therefore, help secure electricity supply.”

“Switzerland wants to convert 100% of its electricity supply to renewable energies by 2050. For this reason, large battery storage systems will play an increasingly important role in stabilizing the electricity grid in the future”, said Frederik Süllwald, Head of Global Sales & Key Account Management at Intilion.

The UK’s first transmission-connected co-located solar and storage project, the Larks Green in Bristol, has signed an asset manager. RES Group, one of the biggest energy multinationals in the world, has been awarded the asset management contract for the facility, which incorporates 70 MW of solar with a 50 MW BESS. RES Group already provides O&M services to the solar farm and has been its asset manager for around a year. It will now also manage the BESS side thanks to the new contract with Cero Generation, owners of Larks Green.
