en.Wedoany.com Reported - HEP Global has broken ground on a hybrid solar-storage plant in the state of Bavaria, Germany. The company states that as solar penetration increases, this hybrid model aims to enhance flexibility.

The project combines a utility-scale photovoltaic array, multi-hour energy storage batteries, and a site controller to optimize energy time-shifting and grid ancillary services. Considering the constraints of the local distribution and transmission grid, the energy storage system will reduce curtailment and support voltage and frequency stability. The next steps include grid connection, commissioning tests, and the integration of the battery energy management system with the plant control system.

According to HEP Global, the solar-storage park plans to offer multiple advantages: the multi-hour battery enables "store then dispatch" operations, suppressing surplus daytime solar generation and releasing it during the evening peak; meanwhile, the site controller adjusts solar photovoltaic and battery output in a unified manner under grid dispatch instructions, enabling the hybrid facility to meet real-time supply-demand balance. The critical feature of a smoothed ramp rate allows for faster tracking, making the system both more economical and reliable in compressing and adapting to high solar penetration conditions, while reducing prediction risk in future electricity trading scenarios.
