The deployment of Li-Ion batteries has exploded in recent years and is expected to enjoy a 30% annual growth until 2030. But those very critical pieces of hardware need a brain to fully function, and that is where software kicks in. In fact, they are two layers of software: the operating system, monitoring the functioning of the battery and the cloud system that interacts with the global electricity system and the power markets. Managing batteries revenues widely differs from geography to geography. Revenues can be categorised in three captions: a) short term ancillary service: daily auctions for primary, secondary, and tertiary reserve b) wholesale electricity market: day-ahead, intraday and imbalance markets; c) long-term auctions such as capacity schemes, voltage control, and last reserve. The battery management software must adapt to those different revenue stacks. So, how are the software developed, managed? How do they evolve? We have the pleasure of welcoming Seyed Madaeni, Chief Digital Officer at Fluence, to discuss those fascinating subjects.Finally, we do a deep dive into the economics of Fluence and have a go at the newly listed (and supposedly competitor) Energy Vault.We thank Aquila Capital for supporting the show.If you want more from Gerard and Laurent, check our sister podcast: Redefining Energy MINUTES, available on all main podcasts platforms.
