Kielce, Poland | February 18-19, 2025 —Dunext, a leading supplier of commercial and industrial (C&I) Battery Energy Storage Solutions (BESS), made a strong impact at ENEX 2025, one of the most influential renewable energy exhibitions in Central and Eastern Europe. The event gathered industry leaders and experts to explore the latest advancements in photovoltaics, energy storage, and grid technologies. As electricity price volatility and grid instability continue to challenge businesses in Poland, Dunext presented its latest PowerHill BESS solutions, demonstrating how Polish enterprises can optimize energy usage, reduce operational costs and enhance grid resilience.

Comprehensive C&I BESS Product Portfolio Taking Center Stage

At ENEX 2025, Dunext’s booth emerged as a focal point, drawing a steady flow of visitors eager to explore tailored BESS solutions for their business needs. The company showcased its comprehensive suite of BESS products designed for diverse C&I applications, including:

PowerHill: Supporting Flexible Business Models for Diverse C&I Sectors

At the core of Dunext’s offerings, the PowerHill C&I BESS solution is designed for 6 critical C&I sectors, including factories, shopping malls, supermarkets, EV charging stations, farms, and small-scale ground-mounted PV plants. With scalable capacity ranging from 143 kWh to 215 kWh and a modular design that supports up to 6 storage cabinets in parallel, PowerHill provides the flexibility required to expand based on growing energy demands.

PowerHill’s advanced features enable multiple business models. It promotes self-consumption by harnessing on-site renewable energy, while its peak-valley arbitrage capability captures low-cost electricity during off-peak hours for discharge when demand is high, substantially lowering energy bills. Moreover, PowerHill delivers reliable backup power during outages to ensure continuous operation and supports grid auxiliary services such as frequency regulation and peak shaving, generating additional revenue through incentive programs.

Robust Local Service Support in Poland Enhancing Customer Confidence

One of the major concerns raised by attendees at ENEX 2025 was the lack of fast and reliable after-sales support in Poland’s energy storage sector. Dunext is addressing this challenge head-on by establishing dedicated service teams and a spare parts warehouse in Katowice, Poland. The company’s proven successful delivery projects across Poland and Europe have earned widespread customer recognition for its product quality and service excellence.

“Poland is a key market for Dunext as we continue expanding our footprint across Europe,” said Tadeusz Ogarek, country manager of Dunext Poland. “With energy costs rising and grid stability concerns growing, our PowerHill BESS delivers a high-performance solution.
