The Mexico-sited Domo de San Pedro Geothermal Power Station is the first geothermal power plant in the world to add Mitsubishi Power’s Tomoni intelligent digital solutions to improve efficiency and reliability. The technology, according to Mitsubishi Power, is proven to increase profitability of gas and steam turbine plants around the world. The solutions are now being applied to improve geothermal power plant competitiveness through asset optimisation, analytics for operator and maintenance support, and artificial intelligence.
Mitsubishi Power built the 25-megawatt Domo de San Pedro plant under a turnkey engineering, procurement and construction contract completed in 2016. Because geothermal production wells change over time and steam conditions diverge from optimal design, geothermal plants must be optimised to compensate for these changes. The Tomoni solutions, which include remote monitoring and real-time data analysis of the plant and geothermal production well, provide the plant with the tools to diagnose and predict operating conditions and to develop optimal solutions that improve plant performance and reliability.
