Cooperative Energy + Wärtsilä

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.

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.

Long-term Wärtsilä agreement will deliver guaranteed performance for Argentinian power plant

Apr 30, 2020, 13:00 PM by Wärtsilä Corporation

The technology group Wärtsilä has signed a 10-year Optimised maintenance and an optional Operational advisory service agreement with one of Argentina’s major energy sector company. The agreement provides a guaranteed performance for a 57.6 MW power plant delivering electricity to its own operations in the south region of Argentina, with any excess power being sent to the national grid. Signing of the agreement took place in March and it will take effect when the plant commence operations. Wärtsilä will recognise the order intake following commissioning.

The scope of the agreement includes remote operational support and maintenance planning, provided by Wärtsilä’s Expertise Centre in Brazil, executing planned and unplanned maintenance, covering both spare parts and labour, and an optional permanent on-site advisor. This broad scope is in line with Wärtsilä’s customer support approach. With Wärtsilä Lifecycle solutions, the company maintains and optimises the plant performance of its customers. This support encompasses technology, software and service expertise as well as a holistic view and understanding of installations on a system level through a long-term service agreement. Each solution is always customized to meet the customer’s needs and operating profile.

The power plant will operate on five Wärtsilä 31SG gas engines, the most efficient gas engine in its class. The power plant is expected to become fully operational later this year and it will be the largest in the world utilising the Wärtsilä 31SG engine. By its ability to reach full output within minutes of start-up, the Wärtsilä 31SG is able to effectively balance the renewable energy input from an adjacent wind farm. This creates an energy system that is essentially a hybrid arrangement.

“Maximising the availability of the plant and reliable operations is essential for the customer. Wärtsilä’s vast experience in carrying out timely maintenance and expertise to advice on the operations to ensure guaranteed performance was a prime consideration in the award of this contract. Our remote engine monitoring capabilities are world-class, and the high efficiency of the Wärtsilä 31SG engines will deliver the reliability and performance expected,” said Jorge Alcaide, Energy Business Director, Americas, Region South at Wärtsilä. 

The site is located in an area where the ambient conditions can be challenging, with wind speeds of up to 180 kilometres an hour, and temperatures ranging from - 15 to + 40 degrees centigrade. The Wärtsilä 31SG is designed to operate efficiently, even in these conditions.
