Trimark Selected by SolarCity to Deploy Monitoring and Control System for 3.75MW Antelope Valley Solar Project

Folsom/ Chatsworth/ Sunnyvale Calif. & Norfolk, VA – Solar developer, SolarCity, has selected Trimark Associates Inc. (Trimark) to design and engineer a browser-based monitoring and control system, and deliver California Independent System Operator (CAISO) metering and secure data telemetry for 3.75 MW photovoltaic (PV) generation site Antelope Valley Solar in Lancaster, CA.

Trimark will deliver a CAISO certified meter, its CAISO-certified T1-S Gateway™ (Remote Intelligence Gateway), and Trimark’s power generation control, monitoring and historian system, T1-S Gateway SCADA™. T1-S Gateway SCADA enables end-to-end management from the operations center to field devices, allowing SolarCity to capture, store and forward data in real-time from inverters, meters and MET stations. Trimark will also provide a meteorological station and network drops. Where appropriate, various components will meet UL safety standards. This end-to-end solution ensures that the Antelope Valley Solar project will have a complete, integrated CAISO-compliant system, as well as full featured controls.

Trimark will also be on the ground-level with SolarCity offering CAISO consulting and support – critical insight through the NRI process that eliminates the guesswork from their path to interconnection.

Trimark’s expertise in delivering comprehensive PV power management solutions is visible in numerous, similar facilities across the United States including utility-scale solar sites Topaz (550 MW), Desert Sunlight (550 MW), and Solar Inverter Control’s for the 20MW Cascade.
