Making BESS warranties work: Contracts vs. reality

<p class="p1"><span class="s1">Striking a careful balance between technical limitations, market ambitions, and contractual realism in operating battery energy storage systems (BESS) is no easy task. Rigid battery warranties can often be a make-or-break factor in BESS asset management.

As a result, performance warranties are becoming one of the most critical – and contentious – topics in BESS asset management today.</p>
