1.5 MW Solar Power Plant
PPE was initially hired to perform the CAISO RIG engineering work, and then brought in again at the end of the project to install a new meteorological (weather) station. PPE went on-site to install the RIG (an SEL 3530-4 RTAC), other ancillary equipment, and run communication cable between the cabinet and devices in the switchgear. Once the site’s ECN connection was online, we were able to connect to the RIG and update its programming, troubleshoot communications issues with the ISO, and perform ISO testing, remotely, from PPE headquarters. Due to irreconcilable issues with getting data to the ISO from the met. station installed by a previous contractor, PPE was brought in to quickly install another met. station just in time to complete ISO testing on schedule. Take a look at the pictures for more details on this solar project.

This solar plant is in a relatively remote area of central California and one of the biggest challenges was working in the summertime heat.
PPE personnel arrived on-site before the cabinet was mounted so we took advantage of the situation and threw it on the tailgate to begin installation and wiring of our equipment.
Once everything was installed and wired we powered up the equipment to verify everything worked as designed before the cabinet got bolted in place.
The cabinet mounted in its final position and all comm. cables connected. This concluded the installation; just waiting on power to the site and ECN connectivity to do commissioning.
PPE personnel had to erect a barrier to the wind and rain for installation and testing of the new weather station. We installed a Lufft 503 with a built-in Plane of Array (POA) irradiance sensor to meet ISO requirements and commission the site.
We did our best to use what we could of the existing met. station installation; we used the existing cabinet, terminal blocks, and power supply to wire and power our equipment.
