IEnova Selects Pxise Energy Solutions for Enhanced Grid Management at Solar Facility in Mexico

SAN DIEGO, April 24, 2019 – PXiSE Energy Solutions, a subsidiary of Sempra Energy (NYSE: SRE), today announced that its new Active Control Software (ACT) has been installed at Infraestructura Energetica Nova’s S.A.B. de C.V. (IEnova) (BMV: IENOVA) 110-megawatt (MW) Pima Solar facility in Caborca, Mexico, to help manage the integration of renewable power to the electric grid.

“Our platform will provide Pima Solar with the latest grid-management technology to achieve operational efficiency, while seamlessly integrating their renewable power generation onto the grid,” said Patrick Lee, president of PXiSE Energy Solutions.

Completed by IEnova in 2018, Pima Solar is utilizing the ACT platform for advanced supervisory control and data acquisition (SCADA) functions, including individual and central monitoring, system control, and frequency regulation to support operations and increase system efficiency.

“PXiSE’s ACT platform is a robust and precise tool to help us increase the efficiency of our operations,” said Carlos Barajas, chief operating officer of IEnova. “We are developing additional renewable projects in Mexico that will greatly benefit from the ACT platform’s ability to scale up and expand the use of this technology to meet our future needs on those facilities.”

PXiSE’s ACT platform provides advanced power-control capabilities and granular, real-time insights into local grid conditions by using real-time machine learning to access critical insights 240 times faster than conventional SCADA systems. The ACT platform is modular, scalable and is easily expanded to accommodate any number of additional energy resources.

The ACT platform does not require any special equipment. It is flexible, runs on a standard Microsoft Windows operating system and uses embedded utility software developed and licensed by OSIsoft. The software uses time-stamped synchrophasor data, generated from sensors on the grid, to enhance, analyze and respond to grid data in real time.

In addition to Pima Solar, PXiSE’s ACT platform currently is in use or is being installed at Sempra headquarters in San Diego; at Con Edison’s Great Valley Solar; and in distribution grids in Australia operated by Horizon Power.

PXiSE Energy Solutions LLC., headquartered in San Diego, is a subsidiary of Sempra Energy and partially owned by Mitsui & Co., Ltd. Formed in 2016, the company develops, operates and markets ACT, a next-generation software power-grid management technology for renewable energy developers and operators, grid operators, commercial property owners and microgrids.
