District Energy St. Paul’s Integrated Energy Vision
Integration is the hallmark of District Energy St. Paul’s system. Many district energy systems around the world focus on one service offering and one fuel source. From its inception, District Energy has envisioned a future that uses district heating and cooling infrastructure to integrate a variety of local, renewable energy sources, and technologies. That vision continues today. Our customers benefit from an integrated system that offers fuel flexibility, critical advantages for green certifications, and helps the community realize the full potential of renewable energy and energy conservation technologies.
District Energy continually moves toward this vision for our systems. Although District Energy’s system integrates cooling, thermal storage, and solar thermal, the system is most famous for integration of waste heat from the biomass-fueled combined heat and power plant. Wood residuals and waste heat serve as two of the primary flexible fuels serving the heating system. Both showcase the integration potential of locally available resources that can also drive rate stability.
We continue to evaluate options for advanced heat recovery, solar cooling, and integrating excess heat from other sources for our system.
