The Wärtsilä 34SG power optimised is a four-stroke, spark-ignited, lean-burn gas engine generating set.
The Wärtsilä 34SG power optimised gas engine is especially suitable for balancing renewable power generation. It provides flexible yet affordable balancing power generation and firming for energy systems with a growing or high share of renewables. It also offers unique fast-starting capability, which enables rapid response to fluctuations inherent to renewable energy. Wärtsilä engine power plants can be delivered both as EPC and Equipment Delivery contracts.
