Germany is the first country in Europe to have implemented generating set certification with detail guidelines for grid code compliance, though other countries are in the process of drafting similar requirements. Grid connection rules in Germany are specified in low, medium, high, and extra high voltage levels. Any power plant connection to the network should comply with these rules.
Niklas Doktar, Director, Solution Design, Wärtsilä Energy Business said the grid code compliance certificate brings the Finish company one step closer to a wide-spread adoption of Wärtsliä engines in Germany to balance rising volumes of intermittent energy supply from renewables.
“Certification of the Wärtsilä 31SG places it in a leading market position for 2-stage turbocharged engines,” he underlined, adding all other gas-fuelled Wärtsilä genset are under certification.
World-class efficiency of 31SG gensets
The Wärtsilä 31 gas engine gas engine generating is typically installed in medium sized de-centralized power plants having multi-engine configurations to provide a plant net load of from 20 to 200 MW.
According to the manufacturer, it offers “the highest available open-cycle efficiency” as well as “unparalleled dynamic capabilities.”
Designed for flexible power supply it allows to backstop high volumes of energy from renewable sources. It creates a balancing link between power generation and consumption, thus providing effective system level resilience.
The engines engine can reach full output in 2 minutes from the start command, allowing for the flexibility needed to balance high levels of unpredictable renewables in the power system. According to Wärtsilä, they can be used for load-following or baseload operations.
The modular design of the genset allow for easy conversions between pure gas, multi-fuel and pure liquid fuel variants. It can also be adapted to run on renewable fuels.
