A technology group, Wärtsilä, has launched GEMS Pulse, a breakthrough predictive analytics solution designed to increase the financial and performance output of energy storage facilities. Batteries generate thousands of data points every second, yet operators often struggle to access and leverage this flood of information.
GEMS Pulse addresses this by transforming complex and largely inaccessible battery and operational data into actionable insights, enabling energy storage asset owners to make informed decisions about asset usage throughout the system’s lifecycle.
As global electricity demand surges and the shift to renewable energy accelerates, energy storage has become increasingly essential for maintaining grid stability. Batteries are a crucial component underpinning grid reliability—and their value is maximised when operated with precision.
Even small inaccuracies can have a big impact: a 5 percent state-of-charge (SoC) error could result in annual revenue loss of approximately $10,000 per megawatt (MW). For a 100 MW/2-hour energy storage system, that translates to up to $20 million in revenue loss over the project’s lifetime.
Many energy storage asset owners leave a significant portion of total capacity unused—often up to as much as 20%—as a buffer against uncertainty in cell health and available energy metrics. GEMS Pulse helps reclaim that margin by providing high-confidence measurements of available energy, cell imbalance, and degradation. With clearer visibility into system health, asset owners can operate with greater precision and confidence.
By continuously monitoring for anomalies, GEMS Pulse identifies potential issues before they impact availability—reducing downtime, lowering operational costs, and expanding capacity available for grid services.
GEMS Pulse also enhances operational flexibility by equipping operators with real-time data to simulate dispatch strategies and evaluate outcomes before deployment. Combined with flexible performance guarantees, operators can optimise battery usage for their strategic goals—with intelligence around constraints like cycles per day, depth of discharge, CP rating (continuous power rating), and operating temperature.
“Our industry is experiencing changes in policy and global trade. 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,” said Luke Witmer, Vice President of Energy Storage Software Engineering at Wärtsilä. “Batteries are fundamental to renewable energy integration and deliver real value, no matter how the market twists and turns or how policies evolve.”
