Solar storage

With 50 GW of licensed projects awaiting connection terms and dealmaking in full swing, the country's largest renewables event returns for its eighth edition on 20 and 21 October.

PV Guided Tours: LONGi ONE is an integrated storage platform for C&I applications, featuring intelligent energy management and a TÜV-certified early warning system at cell level. Watch the video to find out why storage is becoming a key component of modern energy infrastructure.

Both the battery cell and system supplier categories go to the Chinese manufacturer in S&P Global Energy's 2026 Tier 1 Cleantech list, as first-half storage revenue climbs 87.54 percent year on year.

Two hybrid sites at Stouby and Agersted bring European Energy's grid-connected storage in Denmark to more than 375 MWh across 96.75 MW.

Podcast: The Energy Center from ESS Inc. in Oregon is an iron flow storage system offering 1.16 MWh of capacity and 174 kW of maximum charging power. Housed in a single container, the modular unit is designed for a range of commercial and grid applications. Alan Greenshields, Director EMEA at ESS, discusses long-duration storage and the role of redox flow technology using sustainable materials such as iron, salt and water.

CEO Talk: The European energy storage market is growing dynamically, and so are the demands on profitability, safety and system integration. We find out how Ampace is positioning itself in this environment, the role Europe plays for the company, and which advances and technologies are set to shape the market next.

PV Guided Tours: Atmoce is introducing a 25-year warranty on its residential storage system and unveiling intelligent module-level energy management that supports automated snow clearing of solar panels. On the storage side, the portfolio is being expanded with the C&I BattBank, the first AC-coupled, stackable commercial storage system designed for low-voltage operation.

Danske Bank is financing the construction of Indian Queens, a hybrid renewable asset combining a 68 MW solar park with a 47.5 MW / 95 MWh battery system. Commercial operations are expected in 2027, with both generation and storage sharing a single grid connection.

Zelestra has signed a ten-year tolling agreement with Axpo for a 207 MW storage project in northeastern Italy, its first BESS development in the country and one that would make it Italy's second-largest holder of authorised battery storage capacity.

Econergy has closed its second UK storage deal with Santander and EDF this year, underpinning what will become one of Britain's largest batteries operating above two hours.

The Robert Jones and Agnes Hunt Orthopaedic Hospital has switched on a 600 kWh battery system paired with rooftop solar, delivered by ZLC Energy using six Solis PrimePower units. The setup is expected to offset around 75 percent of the hospital's electricity use.

Connection terms for co-located battery storage schemes sharing a single grid access point are expected to reach 500 MW shortly, accounting for half of the capacity cap set out under Greece's latest regulatory framework.

Storage is no longer in question. What matters now is the system it forms with generation, controllable loads and e-mobility, argues Philipp Rasche of ENEO.

PV Guided Tours: Homes are increasingly becoming energy producers. Sector coupling within the building is growing in importance and even electric vehicles are now part of the picture. Gregor Kuschmann and Robert Pawlik of Solarwatt explain which components and solutions make energy independence possible and how buildings are playing a new role in the energy market.

Fresh from its German introduction – and reportedly brisk uptake – the three-phase platform is now available in Austria and Switzerland, pairing a 20 kW hybrid inverter with clip-together 5 kWh battery blocks.

CEO Talk: Growing demand for large-scale storage systems is working in favour of European suppliers. Safety and security are becoming increasingly important. What role does service play, from commissioning through the entire lifespan of the storage system? Fenecon's CEO shares his view.

The Swedish company has signed a two-year operations and maintenance agreement with Copenhagen Energy, covering the Ringsted and Vemmelev battery parks – its first O&M contract in Denmark.

The cell giant lands behind only Sungrow and Tesla in the analysts' first assessment of storage integrators, which weights corporate substance such as R&D, supply chains and finances above product specifications.

PV Guided Tours: HYXI is showing off its newly unveiled Muse AI-Native Energy OS, which transforms energy use from passive backup into active, learning intelligence. Highlights include the Aura all-in-one storage, the AC-coupled Halo micro-storage system and the liquid-cooled Atlas C&I unit.

The global storage specialist has acquired a 300 MW / 600 MWh battery project in Oxfordshire, connecting to the recently upgraded Didcot substation ahead of a planned 2028 commissioning.

CEO Talk: What does the future of energy storage in Europe look like? Safer, smarter and more connected – from commercial rooftops to utility-scale projects. AlphaESS shows how a single open system can link all of these applications together. Find out more about the strategy behind it.

Sungrow's PowerTitan 2.0 anchors a 70 MW / 160 MWh storage plant developed by Delta Capacity, delivered in just 15 months to bring flexibility to the volatile Nordic power market.

New analysis from the government in Skopje sets out how North Macedonia could build a green hydrogen economy by 2050 and connect into a pan-European network with Serbia and Greece.

LONGi shows its new solar-plus-storage portfolio, SolarEdge adds 107 kWh for C&I, Clou and Midea bring 261 kWh of liquid-cooled storage and AlphaESS scales to 6.7 MWh.

According to the world's largest battery maker, the system reaches up to 15,000 cycles at 25 degrees Celsius, and offers higher overcharge tolerance than comparable lithium-ion technology.
