Support Grid Flexibility with On-Site Software for Utility-Scale Solar
The Latimer Flexible Solar Management System uses a novel machine learning technique to accurately calculate High Sustainable Limit (HSL), Potential High Limit (PHL), and Real Time Power Potential (RTPP) for PV Assets. These values allow PV to be reliably respond to grid signals, guaranteeing compliance and reducing system-wide cost.

PV control systems that save by unlocking flexibility
On-site deployment
Latimer Controls's Flexible Solar Management System software integrates on-site with the power plant controller.
Dynamic control algorithms
Novel control systems orchestrate PV system inverters to dynamically manage power output, ensuring grid power signals are met with over 95% accuracy.
Estimate and report reserve power
Our control systems use machine learning to estimate the solar held in reserve under curtailment with industry-leading precision.

Explore how Latimer Controls compares to alternative solutions
For real-time solar HSL calculation and curtailment response
This interactive graph shows real plant behavior during a partially cloudy day at a site in Hawaii. Each line represents a key metric, helping you understand the difference between operations with and without Latimer Controls installed on-site.
How to interact with this demo
-
Click legend items to toggle data on and off. The graph starts by showing HSL accuracy, but you can also compare curtailment response.
-
Zoom in by clicking and dragging. Double-click to zoom back out to the full day.
-
Hover over lines to view exact values at each timestamp.
-
Notice how the dark blue “Latimer HSL” line closely follows the blue-shaded “True HSL” area throughout the day—especially during periods of cloud cover. In contrast, the orange “Single Irradiance Meter HSL” often over- or under-estimates available power.
