In North America, geothermal energy from Enel Green Power rhymes with innovation and efficiency.
Enel Green Power’s 25 MW Cove Fort, 13.4 MW Salt Wells and 33.1 MW Stillwater facilities are the only geothermal plants in North America to use largescale electrical submersible pumps (ESP) for the extraction of geothermal fluid, a cleaner and more efficient technology that ensures zero energy losses.
ESP technology requires equipment to be located 1700 feet underground at 310°F, water creating a challenging situation to monitor and perform maintenance activities.
It is a solution that, combined with innovative software developed by NarrativeWave, a US company specialized in Software-as-a-Service and the Internet of Things (IoT), allows us to prevent failures via the user-directed, self-service analytics developed in their software.
This unique approach dramatically decreases the time to improve operations at our geothermal sites.
Sustainability and innovation
Innovation coupling with sustainability are at the core of EGP’s business, representing a path for constant growth that drives us to find the most suitable partners to implement innovative solutions, pushing the efficiency levels of our power plants higher and higher.
Enel Green Power and NarrativeWave signed an agreement under which we will deploy NarrativeWave’s innovative predictive maintenance software to optimize field operations at its geothermal facilities. This is the first ever use of this technology in North America at geothermal plants with electrical submersible pumps.
“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 customiseNarrativeWave’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.”
– Benjamin Decio, CEO of NarrativeWave
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).
