Important building block for a Mexican infrastructure project

Siemens GSU transformers will help improve the country’s power supply in the future. The new Tierra Mojada power plant in Mexico is currently one of the most important Latin American infrastructure projects. It will be equipped with four generator step-up (GSU) transformers from Siemens in the future. The 400 kV GSU transformers will be integrated by a leading Spanish EPC.

Reliable power supply for Mexico

Energy demand in Mexico is rising steadily. The growing demand for a stable power supply is expected to be satisfied in the future by a new 875 megawatt (MW) combined cycle power plant. A leading Spanish EPC has been awarded the contract to build the plant. The company had previously been involved in designing a number of important infrastructure projects in Mexico.    The power plant will go online in 2019 in Tierra Mojada, near Guadalajara in the state of Jalisco. The generated electricity will then have to be reliably transported to the load centers in Mexico. Generator step-up (GSU) transformers will play a key role. They transform the generated electricity to a voltage level at which it can be transmitted over great distances with very low losses.

Innovative GSU transformers

As the world’s most innovative manufacturer of transformers, Siemens will supply the four GSU transformers required to the leading Spanish EPC. Each transformer has a rated power of 367 megavolt ampere (MVA) and a rated voltage of 400 kilovolt (kV). Together they will ensure that the 875 megawatts from the natural gas-fired combined cycle power plant reliably arrive where electricity is needed.    Delivery of the transformers has been scheduled for September 2018. They will be installed in January 2019. “We are looking forward to helping our customer improve the quality and availability of power in the region with this important energy infrastructure project,” remarks Dr. Beatrix Natter, CEO of Siemens Transformers.

Improved quality and availability

The globally active and very demanding customer has high expectations when it comes to the safety, reliability, and efficiency of the GSU transformers. The Siemens technology meets all requirements and is setting new standards in design and technical efficiency for GSU transformers that can run at full load around the clock.
