Technology group Wärtsilä has been awarded EPC contracts for two power plants in Latin America which together are valued at over $207m.

Wärtsilä will also operate and maintain both of the plants under a 10-year operation & maintenance service agreement that will take effect when the plants commence operations.

Each plant will operate using 11 of Wärtsilä’s 50SG gas engines and together they will produce over 400 MW of power output. The electricity produced will be fed to the national grid in flexible baseload mode. The fast-starting flexibility of the Wärtsilä solution enables the efficient integration of larger amounts of renewable energy, such as solar and wind, into the system.

The two plants are expected to be operational at the end of 2021.

The flexible baseload capabilities of this solution include great efficiency, even in hot ambient temperatures, while the water consumption is zero. The multi-engine assembly enables simple future expansion of the plants should that be required, and high availability is assured as there are always engines running while one may be undergoing maintenance. A multi-engine configuration is also a key advantage for ensuring highest part load efficiency.

These gas engine power plants can utilise natural gas, LPG, synthetic fuels and various bio-gas fuels. Efficiency is high even in simple cycle mode and no gas compressors are needed since the required gas pressure is just 5 bar. Gas engines have excellent environmental performance, since the lean-burn technology that they are based on creates very low emission levels. With the addition of a selective catalytic reduction unit even the most stringent emission standards in the world can be adhered to.

“The high efficiency of the Wärtsilä engines with their quick power ramp-ups provide the flexibility and reliability needed in today’s energy market, which is trending increasingly towards renewable energy,” said Sushil Purohit, vice-president of Americas at Wärtsilä Energy Business.
