What does a motorcycle have to do with BESS maintenance? Find out in Ryan's third post of his blog series "Problems and Solutions"

Battery Energy Storage Systems (BESS) are vital for grid stability and integration of renewable energy. Yet the technical challenges they present are often perceived differently by those maintaining systems day-to-day and those overseeing financial performance. This discrepancy in perspectives can lead to a gap in understanding and addressing technical issues, posing a hidden risk for asset optimization and long-term profitability.

Our annual gathering of the battery storage community, Batteries & Pretzels, brought together leading industry voices offering distinct perspectives on BESS deployment. Kay Schöne (Director Technical Asset Management, GreenFlexibility), and Roberto Jimenez (Executive Director, BW ESS) joined Julian Gerstner (Managing Director, MIRAI Power) to share their experiences and insights from developing and operating large-scale BESS projects . Here’s a look at the key lessons they shared.

The article examines the impact of U.S. Section 301 laws on the battery industry, focusing on Lithium-Iron Phosphate (LFP) and Nickel Manganese Cobalt (NMC) batteries. It highlights recent tariff changes, their implications for U.S. companies, and strategic decisions businesses must make. Battery simulation models are an important tool in navigating these changes.

Prolonging the lifespan of batteries through second life applications is a promising strategy to lower CO2 emissions. The battery second life ecosystem is manifold with diverse stakeholders including automotive OEMs, integrators, battery energy storage system (BESS) operators, insurance providers, battery cell manufacturers, recycling experts, and (technology) service providers. Among these, companies like TWAICE play a pivotal role by providing crucial analytics that guide the decision-making process in battery repurposing and reuse.

Lithium ion battery fires are extremely rare but due to the technical nature of batteries, extinguishing them is a big challenge. It is, therefore, sensible to examine the causes, counter- and preventive measures a bit more closely.

In this article, we’ll explore what sustainability with batteries really means … and how you can make it pay.

As related costs decrease and deployment options increase, more and more, energy storage systems (ESS) are becoming essential for sustainable energy production. The ability to store energy as well as supply it makes the technology suitable for multiple use cases. Understanding all the possible use cases for ESS makes that attractiveness even clearer.

This article discusses residual values, and how transparency into battery health is crucial for improving the residual values of electric vehicles.​

The battery is in its second century. And with more car buyers now opting for electric, it seems a good opportunity to recognize what batteries have done for humankind, and the advantages their technology offers the mobility and energy spaces.

The importance of e-mobility to sustainability and environmental awareness continues to grow. Some of the trends that will be emerging for this year include battery-drive at the cutting edge, image change for batteries, and second life batteries enabled by software analytics.

Even though batteries are a controversial topic, most manufacturers and legislators rely on battery electric vehicles because of its advantages over other alternatives. This article examines why batteries are the future of mobility and play a key role for renewable energies.

Numerous recent recalls showed how much risk is associated with the most important competent of the emission-free mobility. The battery is a highly complex piece of technology that must be tightly analyzed not only during the development but also during operation.

The electrification of mobility is accelerating quickly and turning the automotive industry and other major industries upside down. With electrification the focus shifts away from the engine towards the batteries.

Electric vehicle batteries are costly and sensitive parts, and their performance depends on numerous factors like frequency of charge and discharge, the charging system, driving habits, and external temperature. Until now, it was almost impossible for developers or users of batteries to make any reliable analysis or statement about the current state of the device. However, this information can be now delivered by the digital twin created by TWAICE.

Batteries are highly complex electrochemical systems with different cell formats and chemistries being used. The processes inside the battery also deserve particular attention.

Energy storage is booming, and with growth comes complexity. That’s why TWAICE and Camelot Energy Group, an independent consultancy, teamed up to kick off a new webinar series focused on the BESS lifecycle starting with one of the most crucial phases: planning. This first session packed in practical guidance and real-world lessons for developers looking to future-proof their BESS projects. Here’s a summary of the main takeaways.

“Our goal was simple on paper - firm up PV output and cut diesel run-time - but achieving that reliably meant rethinking every step of commissioning and O&M.” - Laura Perez Amigo, InterEnergy. Let’s unpack the lessons from InterEnergy about operating a battery energy storage system (BESS) for the first time.

In our latest webinar with Energy Storage News, we dug into one question that’s top of mind for everyone working with Battery Energy Storage Systems (BESS) today: How do you turn the mountain of data a BESS generates into real, system-level insights? Here’s what we covered —and why it matters for anyone who wants to squeeze every last megawatt-hour (and dollar) out of their assets.

BESS trading decisions are inherently complex and require careful consideration of price volatility, evolving regulations, and fierce competition. However, one crucial factor is often overlooked: battery aging costs. Read on to find out why BESS owners and operators should include precise aging data in their decision-making.

Battery aging isn't just a maintenance concern—it’s a key factor in the success of a BESS investment. By using simulation models throughout the project lifecycle, developers and operators can improve battery selection, secure more favorable warranty terms, and fine-tune operations – ultimately extending lifespan and maximizing profitability.
