## Summary

Mateo Jaramillo, CEO and co-founder of Form Energy, explains why 100-hour 'multi-day' iron-air batteries are necessary to displace mid-merit gas plants during prolonged weather events that lithium-ion cannot economically cover. He details Form's cost targets of $20/kW for these systems and their specific value propositions for utilities like Georgia Power and Xcel Energy in managing load growth, decarbonization, and transmission congestion. Jaramillo also discusses the competitive landscape, including hydrogen and carbon capture, and the operational reality of dispatching these assets for both capacity reliability and seasonal energy shifting.
