Spectral STELLAR
by Spectral
Energy management and virtual power plant platform that connects solar, wind and batteries to the market, automates bidding, allocation and imbalance correction, and stacks FCR, aFRR, wholesale, imbalance and congestion services. The Energy Exchange tier advertises AI-driven forecasts for generation, demand and prices. PowerField runs its own co-location algorithm through STELLAR at its 28 MWp solar / 52 MWh battery site in Wanneperveen and uses STELLAR's imbalance price forecast (2024-present). Greenchoice uses STELLAR as EMS for a 27 MWp floating PV park with an 11 MW / 22 MWh battery at Bomhofsplas, Zwolle, within Enexis capacity limits (summer 2025-present); Pure Energie and ENGIE use its automated curtailment module; GIGA Storage's Rhino battery was steered by STELLAR from 2020. Traders set the strategy and market actions; STELLAR converts them into control signals within grid and physical limits, with 24/7 monitoring by Spectral.
