Event Description

As building electrification accelerates in Minnesota, managing winter heating peaks while meeting ambitious conservation targets is becoming one of the utility sector's greatest challenges.

Community-scale geothermal systems offer a highly efficient path forward. By leveraging local waste heat and shared thermal resources, these systems can help your programs achieve deep energy savings while mitigating cold-climate grid stress.

During this webinar, Minnesota Community Geothermal Systems: A Path to Decarbonization, Frontier Energy will present the findings of a newly released study. They'll explore two scalable models—utilizing ice rink refrigeration waste heat and wastewater effluent—and how they can fit into your energy conservation portfolio.

Why you should attend:

  • Target High-Value Thermal Anchors: See how utilizing existing infrastructure like ice arenas and wastewater reclamation plants lowers upfront capital barriers and maximizes system efficiency.
  • Flatten Peak Demand: Learn how load aggregation and system diversity reduce peak demand and improve overall system utilization.
  • Analyze Real-World Savings: Review data-driven load profiles demonstrating fossil fuel reductions of 20,000 to 24,000 MMBtu annually and over 600 tons of CO₂ reductions per project.
  • Explore Innovative Utility Models: Discuss how pilot projects, supportive policies, and innovative utility ownership models can overcome high capital costs to accelerate deployment.
