Geothermal energy and predictive maintenance: the latest innovation from EGP

Published on Thursday, 30 May 2019

“This collaboration with NarrativeWave provides us with an innovative solution that will allow for better planning and prediction of maintenance activities at our geothermal sites, reducing costs and increasing productivity. Innovation is core to our continued operational excellence and through partnerships like this one we are able to maximize the performance of our plants to deliver clean, reliable energy to our customers.”

– Stephen Pike, Head of EGP’s Operations and Maintenance (O&M) in North America

Enel Green Power engineers and power plant operators can easily customise NarrativeWave’s software, which monitors and analyses these electrical submersible pumps’ operations using anomaly detection models based on past operational data, automatically alerting operators and making predictive O&M recommendations to prevent costly operational disruptions before they occur.

Through this software, Enel Green Power is better able to predict the maintenance needs of ESPs and to streamline the detection-to-repair process. This will significantly reduce the operational downtime of the geothermal plants, boosting operational efficiency and cutting O&M costs.

Geothermal power’s last frontier

The software technology was first deployed at Enel Green Power’s Cove Fort geothermal plant in Beaver County, Utah, where the company in 2016 added a geothermal injection well, combining geothermal and hydroelectric power at one site.

“We look forward to strengthening our collaboration with Enel Green Power, one of the largest global operators of renewable energy and a proven innovation leader, to jointly develop a solution that can now predict on average 54 days in advance of a possible defect, setting the stage for future operational improvements.”

The technology has now been integrated across the company’s two other geothermal sites both located in Nevada: Salt Wells and Stillwater, awarded by the Geothermal Energy Association for its triple energy solution that combines solar photovoltaics, thermal solar and geothermal to improve efficiency and streamline operations.

Stillwater is the first renewable energy plant to combine the continuous generating capacity of medium enthalpy, binary cycle geothermal power (33.1 MW) with solar photovoltaic (26.4 MW) and solar thermal (2 MW).
