Otter Tail Power’s Thermal Storage Tariff: Delivering Clean, Cost-Effective Industrial Heat

August 19, 2026 in Energy Systems Author: Hallie Turner

A new electricity rate in the Midwest is opening a path to save money for industry, lower costs for other customers on the grid, and make better use of existing clean energy. The new rate, or tariff, enables industrial customers to electrify by using thermal storage to capture only the cleanest, lowest-cost hours of electricity via wholesale market pricing. When combined with time-varying and location-based electricity rates, industrial facilities can secure cost-effective clean energy when supply is abundant and use that energy around-the-clock to produce steam for industrial processes.

Understanding Industrial Gas Regulation in Minnesota’s Clean Heat Transition

December 16, 2025 in Energy Systems Authors: Hallie Turner, Hannah Dobie

Minnesota has a statutory net-zero emissions target for 2050, which will require emissions reductions in the industrial sector. In 2022, the Minnesota Pollution Control Agency found that gas use in the industrial sector contributed to a greater share of statewide greenhouse gas emissions than gas use in residential, commercial, and electricity generation sectors. Decarbonizing industrial gas end uses is challenging due to high heat needs, specialized equipment, and cost barriers associated with alternative technologies. Continue reading »
