Sustainable power generation with the optimal balancing solution

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.

Cooperative Energy, a not-for-profit electricity cooperative covering 432,000 homes and businesses in the US state of Mississippi, was looking to upgrade one of its plants in order to help it supply affordable, flexible and reliable power. 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.

Optimised maintenance agreement.

I wanted to be satisfied with the technology and the people behind it, so we visited Wärtsilä’s factory and testing facilities and met the engineers. This is not just about a product, but the people. I needed to be comfortable with everyone involved in design, installation and maintenance. I was very impressed.
