Battery development: an overview of our content

As the global energy transition accelerates, battery energy storage systems (BESS) have become essential to grid flexibility, helping to balance intermittent renewable resources and ensure reliability. However, as storage installations age, battery degradation will become an increasingly pressing issue, prompting operators to seek out practical ways to restore lost capacity.

When we started TWAICE in 2018, the battery storage market was promising but far from certain. Seven years later, the landscape has changed dramatically. Batteries have become a cornerstone of the energy transition, and with that growth has come new complexity, new expectations, and entirely new opportunities. We’ve grown alongside the market—learning not just how to build better analytics and smarter software, but how to lead, focus, and earn trust in a fast-moving, high-stakes industry. These are the lessons that have shaped how we work, what we build, and how we think about the future.

Want to broaden your network, boost your knowledge, and get inspired? Here are some of the top 2025 BESS and EV events for your calendar, with updated events for the second half of the year.
