GEMS Digital Energy Platform Features

360° Visibility

Provides energy producers with a holistic view into their grid system operations while also pinpointing and isolating any system malfunctions automatically.

Data-Driven Intelligence

Automated decision-making based on real-time and forecasted data (device status, weather, grid measurements, and market data). This intelligence optimises system performance while reducing costs and offers flexible warranty management of multiple battery technologies.

Open & Secure Archictecture

Based on open, standard communications protocols and architected around cyber best practices to ensure both cutting edge performance and security. Hosted in the cloud or behind the firewall of a secured network.

Component-Neutral Technology

Offers the best potential technology solution available in the market, designed for our customers specific project lifetime objective. We integrate seamlessly with distributed resources and devices including: batteries, PCSs, PV solar, wind, hydro, engines, and gas turbines— 70+ installations with 16 battery and 12 inverter types integrated.


Our solutions optimise the operational value and energy performance for the life of the system. The portfolio is specifically designed to adapt to changes in market conditions and rate structures, effectively future-proofing energy storage investments for both energy providers and regulated utilities.

Learn more about GEMS IntelliBidder in our work with RWE Renewables

GEMS IntelliBidder enables Hickory Park Solar to provide Georgia Power a day-ahead firming solar-plus-storage profile.

During our commissioning tests, several load rejections were tested, including loss of wind, loss of engines and loss of demand, and in every circumstance, GEMS instantaneously tracked and maintained the quality of the generation avoiding the load shedding of the grid. This is just one example of how this project will improve operations through automation while helping the island avoid blackouts, achieve greater efficiencies and use more wind power.”
