Industry Feedback on the Electric Power HIL System

“It would reduce our risks and costs

considerably…

The ability to perform commissioning of a

microgrid’s control systems prior to

construction would also reduce the

distribution utility’s perceived technical risk,

thereby increasing our project success rate

and reducing deployment timelines and

costs.”

– Dr. Luis Ortiz, Anbaric Microgrid

“An open source HIL library would accelerate

the entire industry, but the industry isn’t

organized well enough to make this happen.

This is a perfect role for government. We

would contribute engineering support to such

an effort.”

– Schneider Electric executive
