Improving Energy Resilience in Healthcare Facilities Through Data-Driven Hybrid Renewable Strategies
摘要
Healthcare facilities depend on uninterrupted electricity to maintain their core services, yet many remain vulnerable to energy market volatility and rising operational costs. Traditional procurement models, especially those tied to spot prices, offer limited protection against financial uncertainty. This study explores whether a hybrid electricity procurement strategy, combining rooftop solar photovoltaics (PV), battery energy storage systems (BESS), and a fixed-price power purchase agreement (PPA), can offer greater stability and long-term value. A full-year, hourly simulation was conducted using the load profile of a medium-sized European hospital, comparing market-only procurement to the proposed hybrid approach. The hybrid strategy demonstrated reductions in operational costs and exposure to price spikes, while offering more predictable energy spending over time. Although the model assumes stable demand and ideal technical performance, it reflects real constraints in healthcare energy management. When investment costs are included, net benefits accumulate gradually, reaching financial viability in the medium term. These findings suggest that hybrid procurement strategies can support more resilient and budget-aligned energy planning for hospitals, especially when integrated into broader infrastructure and climate goals.
