Optimized Land-Use Efficiency: Sigenergy’s modular BESS units are installed directly underneath PV mounting structures. This clever layout maximises space utilisation, enabling additional solar capacity to be deployed within the existing site footprint. Seamless End-to-End Infrastructure &amp; Project Delivery: Fully harmonised Sigenergy inverters and transformers formed the technical backbone of the plant. Complemented by hands-on on-site technical support during commissioning and coordination with grid operators, these combined efforts enabled the facility to achieve successful commercial operation in early August, strictly on schedule. Power Trading: Turning Stored Energy into Market Value The economic value of intelligent storage was further explored by Christoph Gardlo, COO of ESFORIN SE, who emphasized that the future of energy flexibility relies on co-located assets. Pointing to historical EPEX continuous intraday data, Gardlo noted that rising price volatility creates unprecedented profit opportunities for integrated solar-and-battery projects. By deploying ESFORIN's AI-driven FLEXtrading platform to automate asset management and execute real-time power trades, co-located PV-BESS installations can yield up to three times more revenue than standalone solar plants.
