Flexible power through rain or shine with a Wärtsilä 31SG plant


Enabling an increase in variable generation with more flexible capacity that can rapidly start up when needed.

Intermittent renewable energy generation in the United States has seen a staggering 700% increase between 2008 and 2019, with solar and wind generation accounting for around 350 million MWh of power generation in 2019. The subsequent increase in variable generation means that flexibility is increasingly important in the energy system.

Wärtsilä’s comprehensive solution comprises a plant powered by two gas-fired Wärtsilä 31SG engine generating sets and covered by a 10-year service agreement.
