Energy storage made a big impression on pv magazine Awards 2025 independent expert jurors, who awarded the Projects category prize to a BESS installation for the first time.
In a year which saw storage and flexibility become an increasingly hot topic for the solar industry, the BESS category was again one of the most popular among entrants. Jurors had a tough task selecting winners as some entrants debuted entirely new approaches to energy storage, while others demonstrated continuous performance optimization, including round-trip efficiency gains, capacity utilization and degradation.
Projects
Winner: Wärtsilä Energy Storage, Blackhillock BESS
In a year in which grid stability, flexibility and storage have come into the spotlight the 2025 Projects award goes to a battery energy storage system (BESS) installation that delivers world firsts that are sure to be emulated.
Blackhillock energy storage facility is a 200 MW/400 MWh system developed by Wärtsila Energy Storage in partnership with owner and operator Zenobe and is the first BESS in the world to deliver true synthetic inertia and short-circuit level support.
Highly commended: Apollo Energy Analytics, Performance and Reliability Optimization in UAE Solar.
BESS
Winner: Stabl Energy, high performance second-life BESS
Stabl’s commercial and industrial (C&I) integrated battery storage system combines the benefits of second-life batteries with a novel modular multi-level converter (MMC) technology for increased efficiency and optimized sustainability. The status quo of battery storage systems is connecting multiple battery modules in series. This approach means the chain is only as strong as its weakest link, with performance limited by the weakest module.
Highly commended: Noon Energy, ultra-long duration energy storage battery
