Featured Projects

A BESS system of 240MWh is being added at the existing 280MW PV plant. The team added new plant controls and SCADA to integrate BESS into the PV plant. It will provide many of the advanced features required for co-located solar and storage resources in CAISO market.​

• Automated Dispatch System (ADS) & Automated Generation Control (AGC)​
• Up and Down Regulation​
• Solar Dispatch on Target (DOT) variation control with storage​
• LGIA Limit Compliance Control
• Energy Shifting​

A PV plant with 18MW DC capacity was built in the Bin Thuan province. The team added a new low-cost table-top wall-mount SCADA and plant controls product for this project. It provides many of the advanced controls, SCADA and cybersecurity features required for international solar market.​

• Tabletop or wall mounted SCADA.
• Suitable for community style and industrial projects with a small footprint.
• Plug and play device with zero site assembly requirement.

At the time of its commissioning in November 2019, the Phoebe PV solar plant is the largest solar plant in the State of Texas. In addition to all the grid friendly features implemented at other plants, it demonstrated:

• Advanced voltage stability controls in weak grids.

A 26MWh BESS system was added at this existing plant. The team upgraded new plant controls and SCADA to integrate BESS into the PV plant. The system now provides several advanced features:

• Energy Shifting
• Dispatch Scheduling
• Firm Capacity
• Up and Down Regulation and Frequency Control
• Load Following

The Luz del Norte plant is one of the largest photovoltaic (PV) solar power plants in Chile. Its control system was upgraded to deliver a range of grid services to Chile’s independent system operator (ISO), including automatic generation control (AGC) to support the grid’s reliability and stability.

• World’s first commercial delivery of ancillary grid services from a solar plant.

Agua Caliente is one of the first utility-scale PV plants of its size (290 MWac) to be connected to a 500kV transmission line in 2011. It employs First Solar’s industry-leading grid integration and plant control system. It pioneered many of the following grid-friendly features that are critical for managing grid reliability and stability.

• Regulate voltage, frequency, and power factor.
• Control active and reactive power, ramp rates, and curtail power when necessary.
• Ride through grid faults and disturbances.
• Minimize the impact of passing clouds through intelligent plant controller.

When Desert Sunlight Solar Plant was commissioned, it was one of the largest PV plants in the world. It also contains the leading grid control capabilities that were pioneered at the Agua Caliente plant.

• Control and manage two separate grid connections (with PG&E and SCE)

‍

The Topaz Solar plant was one of the largest PV plants when it was constructed. It also contains the leading grid control capabilities that were pioneered at the Agua Caliente plant.

• Control and manage multiple inverter types (2 different models of ABB inverter and 1 model from SMA)
