Presented during the NetZeroCities Spring School, this resource shares learnings from Lappeenranta’s BeyondEE district heating demand response pilot. It explores how low-temperature district heating, dynamic energy production, multi-source energy systems, storage, smart metering, forecasting and system optimisation can improve energy efficiency and flexibility. The presentation highlights practical lessons on procurement, monitoring, fault detection, scalability and business case development, including average energy savings of 7% and stronger returns when demand response is included.
