Storage is a financeable asset, meaning operators can deploy substantial BESS capacity without reducing liquidity or slowing expansion. . Battery energy storage systems (BESS) can help address the challenge of intermittent renewable energy. Large scale deployment of this technology is hampered by perceived financial risks and lack of secured financial models. Global energy storage capacity additions exceeded 15 GW in 2024, with lithium-ion battery costs declining 90% over the past decade to. . In this article we consider the role and application of battery energy storage systems (BESSs) in supporting renewable energy power generation and transmission systems and some of the challenges posed in seeking to project finance BESS assets. Bankability was a hot topic for many attendees. | Image: pv magazine / Marian Willuhn.
