In the real world, use cases include everything from ensuring a more reliable supply for a major city, that experiences frequent power outages due to increasing demands on the electrical grid, to regulating hydroelectric facilities, where wind speed changes and power output fluctuations can destabilize the grid. In areas transitioning from coal or gas power plants to renewable energy sources, Fluence can provide rapid response capabilities and maintain grid stability and reliability. While in a region with abundant sunlight, a solar farm can capture and store excess solar energy during the day to be dispatched later in the most efficient manner.


The urgency of climate change is demanding a global pivot away from fossil fuels toward sustainable energy systems. However, the intermittent nature of renewable energy remains a key challenge. Since sources like wind and solar are not consistent, the need for energy storage that can act as a buffer and make renewable energy available 24/7, has never been more pronounced. Furthermore, growing capacity constraints on existing power grids that were not designed to support distributed and renewable generation infrastructure or the accelerating electrification of industries, such as transportation, is driving demand for more generation, and positioning energy storage assets as a key solution.

Energy storage can help both serve and smooth additional peak demand, improving grid reliability and managing energy requirements. Beyond that, it is also a flexible tool, allowing grid planners, operators, and providers to navigate the evolving energy landscape. Consequently, grid modernization, decarbonization, and digitalization is redefining energy market infrastructure. It is estimated that this energy transformation will require $134 trillion of investment through to 2050 based on Bloomberg New Energy Finance’s clean electricity and green hydrogen pathway.

Government incentives and regulations are acting as catalysts, as various policies and legislation to support the transition from fossil fuels to low-carbon forms of energy have been announced and implemented around the globe. The U.S., in particular, has been proactive, passing the Inflation Reduction Act (IRA), which includes several incentives that support the adoption of energy storage products and services and are anticipated to benefit Fluence significantly.

A forecasted reduction in battery costs is expected to improve the economics of energy storage and support the development of larger energy storage systems. Moreover, in July, Fluence signed a battery cell supply agreement with AESC, under which the company will procure U.S.-manufactured battery cells. This positions Fluence to be one of the first to provide customers with a storage product that qualifies for a 10% Investment Tax Credit bonus for using domestic content under the IRA.

Fluence intends to further develop its energy products, services, and digital applications into solutions that solve ever-evolving use case challenges. In the last quarter, the company launched a predictive maintenance feature for battery energy storage on the Nispera application. It is also focused on expanding standardized offerings that are optimized for varying sales channels with a more localized, regional operating model to better support customers and improve logistics.

Mass manufacturing is a cornerstone of Fluence’s product delivery approach and a key to driving down product cost and delivering at scale. As a result, the company is also aiming to create an optimized production organization, develop mass manufacturing facilities globally, and continue to secure partnerships with key battery suppliers. It is anticipated that enhancing this product-focused model and supply chain leverage will support global growth objectives and result in superior unit economics.

To this end, in late 2022, Fluence partnered with a contract manufacturer to open a new manufacturing facility in the U.S. to better serve regional delivery and address ongoing supply chain constraints. The addition of this facility expanded the company’s production beyond Asia to meet increasing global demand, allowing it to better serve regional markets. While future plans intend to add more manufacturing sites in Europe.


Fluence has experienced a remarkable journey in revenue growth, with its most recent quarterly revenue hitting $536.4 million, marking an astounding 124% increase year-over-year. This surge has propelled the trailing 12 months’ revenue close to $2 billion, more than doubling from the previous year. The uptick in total revenue was largely driven by amplified sales of their battery-based energy storage products and solutions, albeit partially offset by a reduction in augmentation services. The robust growth is attributed mainly to the heightened demand for Gen6 solutions across all regions and the achievement of select project milestones ahead of time.

Fluence has also made strides by improving its GAAP gross profit margin to 4.1%, a significant leap from the negative 2.2% during the same quarter of the previous year. This shift was realized after executing legacy low-margin backlog and focusing on newer Gen6 solutions projects that promise higher margins. While the company recorded a net loss of about $35.0 million, this was an improvement from the $60.8 million loss during the same period last year.

Adding to its achievements, Fluence reported a healthy backlog, increasing its pipeline by over $1 billion to approximately $2.9 billion. The company not only executed its projects timely during the quarter, it also fortified its total cash position by more than $30 million to be just short of $300 million.

Looking ahead, management is forecasting to close out FY23 with total revenue of $2.0 billion to $2.1 billion, marginally exceeding consensus expectations at $1.96 billion, which represents still impressive year-over-year growth of 63%. Earnings per share are also forecasted to improve remarkably, going from a loss of $2.69 to a loss of just $0.57 in 2023, marking a 79% improvement.
