As renewables increasingly replace traditional baseload generation, there’s a growing need to shore up the grid’s stability with balancing capacity. Power producers need to invest in flexible technologies that provide fast-ramping balancing power and that can be scaled up as the share of renewables in the power system increases.
The Wärtsilä 31SG power optimised engine solution is designed to provide flexible grid capacity even in adverse weather conditions – which means that renewables can always perform as the lowest-cost, most resilient power source for grids worldwide. It gives you the flexible capacity you need with a low initial investment and optimized OpEx for balancing applications. The solution is based on three key components: the Wärtsilä 31SG power optimised engine, prefabricated modules for cost-efficient plant construction, and Wärtsilä Lifecycle services.
LOWER YOUR COST PER KW
Now that the Wärtsilä 31SG in 8% more power, it is the most powerful engine in its size category.
SPEND LESS ON PLANT CONSTRUCTION
Prefabricated, quality-controlled modules mean faster plant set up so you can start producing power more quickly.
GET PREDICTABLE COSTS WITH LIFECYCLE SERVICES
Remote support enables leaner operations and Wärtsilä can guarantee plant performance.
BENEFIT FROM A FUTURE-PROOF INVESTMENT
Operate on natural gas, biogas or hydrogen blends already today and convert to run on future fuels.
Subscribe here to ensure you will be included in our invitation list for the upcoming webinar on how Wärtsilä 31SG Balancer enables renewables at lower cost.
Our next-generation balancer is a power-optimized version of the ground-breaking, ultra-efficient Wärtsilä 31SG. Now bringing you even more power while still maintaining high efficiency for the same investment, the Wärtsilä 31G power optimised engine is an ideal solution for balancing renewable power generation. The solution is cost-efficient as you need fewer engines to meet demand and can still benefit from low fuel consumption and reduced emissions.
With our cost-efficient plant construction based on prefabricated, high-quality power plant modules, you can start generating power faster. The design allows you to pick and choose the desired functionality and equipment based on your project need.
The heart of the plant is the power unit that consists of the engine and the essential equipment. This can be installed on location in days instead of weeks to start generating power more quickly for lower costs and faster ROI. The power unit can be complemented with process modules that enable easy integration of auxiliary equipment, process media, and filtration. We also provide electrical modules that enable integration of the low voltage and medium voltage systems.
Wärtsilä Lifecycle Services support you in de-risking your investment with customized plans to help you meet your specific needs during the lifecycle of your power plant. We’re here to support you with efficient operations and maintenance plans. We can tailor performance guarantees with a predetermined outcome, as well as the included products and services in order to deliver expected lifecycle value.
Both remote and on-site support is available through data connectivity and digital technologies. Wärtsilä’s Expertise Centre in Houston features advanced technology and highly developed security. Our customers can receive 24/7 support, along with unmatched guidance, real-time data analytics, and quick response to plant issues.
With Wärtsilä, you won’t be stuck with stranded assets as our engines are flexible. This means that whatever fuels become dominant in the future, Wärtsilä engines will be capable of adapting efficiently to any single or combination of fuels. Indeed, today, the Wärtsilä 31SG power optimised can already be run on natural gas, biogas, and hydrogen blends to help keep emissions to a minimum.
