Technical support from the EPE team was invaluable. The interface with our project partners was seamless, and the interconnection process was effortless.
We wouldn't have been able to reach the milestone of beginning commercial operations without EPE's guidance and partnership. When I say partnership, I mean that. We're on the same team, working toward the same goal.
AES has found EPE incredibly professional, informed, flexible, responsive and knowledgeable. They work under extreme time pressure, are very diligent and thorough and are a pleasure to engage with.
