We appreciate your interest in Wärtsilä's solutions. Please have a look at the material provided below. These are suggestions and recommendations from us. We hope that this can be the basis for further discussions and eventually a proposal for you.
Here is a visualisation of a power plant that is of similar size as you selected (click on the image to view full screen). When we deepen our discussions we can provide a layout visualisation that is according to the exact specifications of your power plant project.
Based on your selections we suggest that you familiarize yourself with our range of gas engines. Once we have a deeper understanding of your power plant needs we can further define which specific engine model is most suitable for your power plant project.
The main products in our gas engine range are presented here:
Wärtsilä 34SG (ca 10MW unit) - agility and flexibility combined with high efficiency over the whole load range and in any operating profile makes this plant excellent for both flexible baseload and peak load, and supporting the grid with a variety of ancillary services.
Wärtsilä 31SG (ca 11 MW unit) - this is the newest and most efficient gas engine we offer. Wärtsilä 31SG takes efficiency to a new level for internal combustion engines.
Wärtsilä 50SG (ca 18MW unit) - High efficiency in a small footprint combined with high reliability and flexibility makes this solution perfect for flexible baseload applications including daily starts and stops, also providing ancillary services like regulation up&down and tertiary reserves.
However, droughts and diminishing reservoir levels in recent years have threatened capacity sufficiency. With supply deficits projected to occur by 2016, new thermal plants are needed to meet the country’s growing power requirements. By integrating natural gas production with power generation, ENEVA’s Parnaíba Complex in Brazil’s northeastern state of Maranhão provides access to a guaranteed fuel supply and reliable energy production.
Although Parnaíba I, II and III gas-fired power plants were under construction, free market demand for flexible, low-cost power led to development of the usina termelétrica (thermoelectric power plant) Parnaíba IV. The plant was fast tracked for completion, with a timeline of about one year from contract signing to commissioning.
Meeting this ambitious schedule required a company with the experience and resources to undertake full engineering, procurement and construction (EPC) and the technology to deliver efficient power generation with high availability. Wärtsilä was selected by ENEVA to provide the complete “gas to wire” solution for Parnaíba IV that included all equipment and infrastructure needed to generate power. Parnaíba IV is a 56 MW power plant comprised of three Wärtsilä 18V50SG gas engines.
It is the first power plant in Brazil to employ the Wärtsilä 50SG engine, the largest gas engine on the market. The Wärtsilä 50SG engine has a high efficiency rating of nearly 50% and can provide quick start, fast ramping, and reliable baseload capabilities. By combining multiple Wärtsilä 50SG generating units into a single plant, Wärtsilä’s technology solution mitigates the risks associated with maintenance outages.
The modular architecture of Wärtsilä power plants affords the ability to rapidly and frequently change load without sacrificing efficiency or affecting the maintenance schedule. In addition, some engines can be offline while still retaining the bulk of plant output, offering high power reliability. The technical and economic benefits of flexible power generation led to the selection of internal combustion engine (ICE) technology for Parnaíba IV.
