DNV GL has awarded a Type Certificate of grid code compliance for Siemens Gamesa's hybrid power plant La Plana: Storage, wind and solar near Zaragoza, Spain. Siemens Gamesa contracted DNV GL to carry out grid code compliance certification on the entire plant without diesel gensets.The certification was carried out using a tailored approach that followed the procedure defined in the DNVGL-SE-0124 certification of grid code compliance service specification. As part of the approach, DNV GL developed new tests for hybrid-specific control functions that are not currently covered by international guidelines. The La Plana pilot plant was commissioned in 2015 to explore the potential of hybrid power. It combines 850 kW of wind power, 245 kWp of solar photovoltaic panels three optional diesel generators and two types of battery energy storage technologies with a hybrid plant controller (HPC) that manages the mix of generating technologies in real time.
