A geothermal power plant in Mexico is installing Mitsubishi Power’s digital solution to increase performance efficiency and operations as the steam potential changes over time.

Mitsubishi Power is applying its TOMONI line to the Domo de San Pedro Geothermal Power Station in Nayarit, Mexico. The company historically has utilised TOMONI in gas and steam turbine plants globally, and calls this geothermal application a first.

“It is of great support to have Mitsubishi Power together with our team closely monitoring the plant, analyzing our data and developing solutions to ensure that we can provide reliable clean power to our customers,” Juan Luis Del Valle Luarca, operations director at Geotérmica para el Desarrollo S.A.P.I. de C.V. (GEODESA), said in a statement.

The Japanese manufacturing, engineering and contracting team built the 25MW Domo de San Pedro geothermal plant in 2016. These renewable, zero-carbon production wells evolve over time and steam conditions, diverge, so the plants need adaptation tools at their disposal.

“Geothermal power plants are important contributors to energy sector decarbonization,” said Marco Sanchez, vice president of intelligent solutions at Mitsubishi Power. “Because they rely on renewable underground reservoirs for steam to rotate turbines rather than on fuel combustion, they have zero carbon emissions. Geothermal wells present unique plant management challenges that Mitsubishi Power icehas been excited to model and optimize with our digital solutions for the Domo de San Pedro Geothermal Power Station.”

The company already is a major maker and supplier of geothermal steam turbines, so the company considered the TOMONI digital solution a logical extension of its geothermal services.

Mexico has more than 1,000MW of installed geothermal capacity. The resource makes up close to 3% of the generation mix.
