BESS returns are only as good as the assumption that assets perform the way contracts and warranties promise. ACCURE’s independent monitoring across more than 50 projects, over 10 GWh of capacity and 7.5 million readings, shows they often don’t: sites running below contracted availability, delivering less energy than capacity tests implied, and running on thinner margin over nameplate than most financial models assume. Alan Coller, Head of APAC and MEA at ACCURE Battery Intelligence, unpacks what these gaps mean for lenders and investors backing BESS assets in Australia and across the region, and how clearer visibility into real performance translates into sharper risk pricing and more predictable returns.
