Battery storage sector prepares for first wave of large-scale project augmentations
Excerpt
The battery storage sector is about to enter its first ever phase of large-scale augmentations of systems as they reach 3-5 year degradation points and there are questions over how this will pan out, a representative of Burns & McDonnell told Energy-Storage.news.
“Most battery storage projects will add or replace battery capacity within the first three to five years as those existing batteries degrade, typically by 5-15% in that period. There are a lot of questions as we hit this first round of augmentations because we really haven’t seen augmentations executed in a major way yet,” said Jason Barmann, Energy Storage Technology Manager for the engineering, procurement and construction (EPC) firm.
