Ormat Technologies
Ormat Technologies optimizes geothermal energy production with AVEVA solutions
Ormat Technologies, a global leader in renewable energy and the foremost player in geothermal power, operates plants running 24 hours a day where reliability and performance optimization are essential. The organization lacked optimal geothermal output, data access was tedious, and critical thermodynamic calculations were performed manually in Excel, for lack of an integrated analysis and visualization solution. In partnership with Casne Engineering, Ormat gained access to AVEVA Plant SCADA and AVEVA Historian, and integrated AVEVA PI System, AVEVA PI Server and AVEVA PI Vision into its workflow. The benefits are remarkable: an average of $1 million in additional revenue per plant per year thanks to 1 to 3.5 MW of additional output per site, predictive maintenance savings not yet accounted for, and the development of an asset hierarchy, actionable dashboards and a custom thermodynamic calculation solution. Ormat now has enhanced situational awareness and real-time analytics on its critical processes.

FAQ
How does AVEVA PI System improve output at a geothermal power plant?
Ormat Technologies, a global leader in geothermal energy, integrated AVEVA PI System, PI Server and PI Vision with AVEVA Plant SCADA and AVEVA Historian. This unified platform makes it possible to analyze in real time the parameters of plants running 24/7 and optimize operating points. The result: 1 to 3.5 MW of additional output per site, or an average of $1 million in additional revenue per plant per year. Data management becomes a true performance lever for renewable energy.
Why replace manual thermodynamic calculations in Excel?
Ormat's critical thermodynamic calculations were performed manually in Excel, a source of errors, slowness and lack of standardization. Using AVEVA PI System and AVEVA PI Vision, partner Casne Engineering developed an integrated, customized thermodynamic calculation solution that automates these operations in real time. Engineers now have enhanced situational awareness and immediate analyses of critical processes, freeing up time for strategic optimization rather than repetitive tasks.
What does AVEVA Plant SCADA bring to monitoring a geothermal power plant?
AVEVA Plant SCADA and AVEVA Historian provide 24/7 industrial monitoring of Ormat's geothermal power plants. Since reliability and performance optimization are essential in this context, the SCADA + Historian combination ensures equipment availability, quality information for operators and the historical traceability needed for analysis. Integration with AVEVA PI System amplifies the value by exposing data across the plant portfolio, turning each site into a source of learning for the others.
How does an asset hierarchy speed up access to data?
Before AVEVA, accessing data was tedious at Ormat. The asset hierarchy built on AVEVA PI System logically structures each plant, each piece of equipment and each variable. Engineers navigate this tree intuitively and reach the information they need in a few clicks. Actionable dashboards designed in AVEVA PI Vision present key KPIs in real time. This structure is the basis for optimized operation of geographically distributed geothermal plants.
What ROI can an AVEVA project generate in renewable energy?
Ormat Technologies generates an average of $1 million in additional revenue per plant per year thanks to AVEVA PI System, PI Server, PI Vision, Plant SCADA and Historian. On top of this revenue come predictive maintenance savings not yet accounted for and the strategic contribution of actionable dashboards. Across a portfolio of geothermal plants, this cumulative ROI represents considerable value creation and sets a new industry standard for performance management in renewable energy.
