At Intersolar & Energy Storage North America (IESNA) Flagship 2026 in San Diego, we spoke with Jon Parrella, Founder of Terraflow Energy, and Anna J. Siefken, Director for Policy and Markets, North America at the Long Duration Energy Storage (LDES) Council, about the growing intersection of data centers, artificial intelligence (AI), and clean energy. They discuss the regulatory hurdles facing new energy capacity buildout, why energy storage is critical to meeting hyperscaler power demand, and the advantages solar energy holds over natural gas for powering data center growth.
