Wärtsilä has introduced GEMS Pulse, a predictive analytics platform designed to maximise the financial and operational performance of battery energy storage systems (BESS).
The software transforms vast volumes of battery and operational data into actionable insights, helping asset owners optimise usage across the lifecycle of their systems.
As electricity demand rises and renewables scale up, energy storage is critical to grid stability. Yet even minor inaccuracies can be costly – a 5% state-of-charge (SoC) error could mean $10,000 lost per megawatt annually. For a 100MW/two-hour system, that’s up to $20 million over its lifetime.
Many operators leave up to 20% of capacity unused to hedge against uncertainty in cell health and energy metrics. GEMS Pulse helps reclaim this margin by offering high-confidence measurements of available energy, cell imbalance and degradation. It also monitors for anomalies, reducing downtime and expanding grid service capacity.
Luke Witmer, vice president of Energy Storage Software Engineering at Wärtsilä, said, “GEMS Pulse reduces risk and strengthens the long-term economics of clean energy. It gives customers real-time visibility and predictive intelligence so they can run their assets with confidence and speed.”
The platform enables real-time simulation of dispatch strategies, supports flexible performance guarantees, and provides intelligence on cycles per day, depth of discharge, CP rating and temperature.
Already deployed across Wärtsilä’s portfolio, GEMS Pulse has optimised over 9GWh of battery capacity. Ruchira Shah added: “We are empowering customers to access and understand their own data. This is a meaningful competitive edge in a fast-changing energy market.”
