The software connects forecasting, value stacking, real-time dispatch, and financial optimization in one place, aimed at owners, operators, and developers of solar, storage, and hybrid energy assets who want a clearer view of what their portfolio is earning and where it could earn more.
For project valuation, it combines solar and storage data into scenario-based financial forecasts, giving site-level insight for investment and planning decisions. For wholesale market participation, it supports registration, scheduling, and real-time trading decisions, with settlement tracking and reporting on results. For utility bill optimization, it manages tariffs, demand response, and energy arbitrage, adjusting battery charging and discharging automatically to capture savings. For grid services, it handles event preparation, real-time dispatch, and power quality management for demand response and grid programs across North America.
PowerTrack Optimizer is designed to work alongside Stem's Managed Services and its Remote Operations Center team, rather than as a standalone piece of software; Stem positions the combination as a way to simplify operations while still capturing the full value of an energy portfolio.
Stem describes itself as backed by nearly two decades of experience managing clean energy projects, and states that it operates the largest virtual power plant (VPP) in North America, with a dedicated Remote Operations Center resolving issues on managed assets year-round.
Stem frames its pitch around three points: credibility from thousands of successfully managed clean energy projects, coverage across the full asset lifecycle from system design through ongoing operations, and market and operational insight meant to support grid-ready, revenue-focused decisions in a complex energy landscape.
PowerTrack Optimizer sits alongside the rest of the PowerTrack Suite, which covers energy management software (EMS), power plant controls (PPC), SCADA monitoring, and data logging, so a single asset owner can combine economic optimization with the monitoring and control layers underneath it.
