Comprehensive DNV analysis confirms strong operational performance, providing a verified benchmark for consistent uptime and revenue support
ARLINGTON, Va., June 09, 2026 (GLOBE NEWSWIRE) -- Fluence Energy, Inc. (“Fluence”) (NASDAQ: FLNC), a global market leader delivering intelligent energy storage systems, services, and asset optimization software, today announced results from an independent review conducted by DNV, the independent energy expert and assurance provider, confirming 99.3% availability across Fluence’s reviewed operating battery energy storage fleets of 50 MW and above.
DNV reviewed Fluence-provided fleet-level availability data, the calculation methodologies incorporated into the company’s contracts, and operational data for select projects. The assessment validated Fluence’s internal findings of 98.7% MW-weighted availability across the reviewed Fluence global fleet of energy storage projects.
“Customers invest in energy storage to deliver power exactly when it is needed, and every minute of downtime represents lost revenue and grid vulnerability,” said John Zahurancik, Chief Customer Success Officer, Fluence. “We worked with DNV to establish a validated benchmark that Fluence customers can count on. Fluence systems are delivering availability among the best-performing power assets in the world, including thermal generation, renewable power, and other energy storage, maximizing the return on investment.”
The DNV review was designed to provide greater transparency into how Fluence systems perform at operating scale throughout the last year. The study assessed fleet-level availability using operational data, applied a consistent methodology across markets and operating environments, and included independent evaluation of the underlying assumptions, methodology, and results.
Across the energy storage industry, availability figures of 95% to 98% are often promoted. However, definitions and measurement approaches vary, which can make it difficult for customers, investors, and asset owners to compare performance across suppliers. Customers experience performance in practical terms, by a system’s operational availability to deliver energy on demand. To guarantee this reliability, they require clear, third-party validated metrics.
“As batteries take on a larger role in ensuring grid reliability, there is increasing need for greater confidence in how performance is measured and understood. Transparent, consistent availability metrics are key to unlocking further investment and grid reliability to meet the increased load growth,” said Marion Hill, Executive Vice President and Region Director, Energy Systems North America at DNV. “DNV worked with Fluence to confirm that their availability methodology is applied consistently and provides clear, comparable insight into fleet level performance.”
The commercial impact of availability can be significant. Even small differences in availability can affect project revenue, operating costs, and long-term asset value, particularly as storage assets operate across different markets, duty cycles, and conditions.
The review represents one of the industry’s more comprehensive independent assessments of fleet-level battery storage availability. As power demand grows from electrification, industrial load, and AI data centers, independently reviewed operating data can help customers distinguish which storage assets are built to deliver dependable, flexible capacity at scale.
