This study investigates cost-optimal dimensioning of a kindergarten hybrid energy system over a 25-year life cycle. Findings show high peak power demands make power fees dominate the total district heating costs. Consequently, varying district heat tariffs—considering waste heat integration—minimally impact the dimensioning, potentially undermining the waste heat utilization in district heating.
