A new study by Georgia Institute of Technology researchers examines whether electrified supply chains can provide a new source of long‑duration demand flexibility for the electric grid, helping integrate variable renewable energy such as wind and solar.

The paper, authored by EPIcenter faculty affiliate Constance Crozier (School of Industrial and Systems Engineering, Georgia Institute of Technology), EPIcenter student affiliate Rina Davila Severiano (School of Industrial and Systems Engineering, Georgia Institute of Technology) and Mark O’Malley explores how electrifying both industrial manufacturing and freight transportation could allow electricity demand to shift over days or even weeks — far longer than the hours‑long flexibility commonly associated with electric vehicle charging or battery storage.

Using a case study of the cement industry along the U.S. East Coast, the authors model a fully electrified supply chain spanning 20 cities, two manufacturing hubs, electric truck fleets and warehouse storage. Their analysis shows that, by adjusting manufacturing schedules and inventory levels, electrified supply chains could shift tens of gigawatt‑hours of electricity demand to better align with renewable availability, particularly wind power, whose output varies over longer timescales. They find that this flexibility can emerge under relatively modest carbon price signals — below $50 per ton of CO₂ — well before grid‑scale battery storage becomes economically viable.
