AC or DC? How grid congestion reshapes the hybrid BESS decision

JUL 22, 26 | 11AM (CEST)     IRENE NEGRO     

Grid congestion is rewriting the hybrid BESS playbook. When export capacity is capped, the choice between AC and DC coupling has direct consequences for dispatch efficiency, curtailment recovery, and project revenue — and the configuration that wins isn't always the one you'd expect. 

In this 45-minute session, Irene Negro (Lead Principal Consultant at RatedPower) cuts through the noise with a direct comparison of AC and DC-coupled BESS under grid-constrained conditions — showing how each configuration affects revenue capture and financial performance when export limits are in play. 

🔍 What you'll learn 

  • Why the "standard answer" on AC vs DC breaks down under grid congestion — and what actually drives the difference 

  • How curtailment recovery works differently in AC and DC-coupled systems, and why it matters when your delivery point is capped 

  • How to compare arbitrage performance, LCOS, and hybrid LCOE between both configurations using the same project inputs 

  • Which project conditions tend to favour each coupling method — and how to test your own scenario 

If you're developing or engineering hybrid solar + storage projects in markets where grid capacity is becoming a constraint, this session will give you a practical framework for making the coupling decision with confidence.
