Medical Facility Energy Procurement in Illinois
Last reviewed: 7/31/2026
By Illinois Commercial Energy editorial team · Reviewed by JakenEnergy commercial energy team
Medical facilities — hospitals, clinics, surgery centers, and medical office buildings — are continuous, tightly controlled energy accounts with both significant electricity and significant natural gas load. For Illinois healthcare operators, procurement is one lever among several, handled alongside reliability planning.
Who this is for
Facilities directors, engineering leaders, and finance teams at Illinois hospitals, clinics, ambulatory surgery centers, and medical office buildings, including multi-site health systems.
The medical facility load profile
- Continuous, controlled HVAC — ventilation, humidity, and temperature control for patient areas and equipment run 24/7.
- Clinical and imaging equipment plus around-the-clock lighting.
- Natural gas for space heating, domestic hot water, and sterilization — a meaningful commodity where the gas utility depends on location.
Reliability vs. supply are separate
A supplier contract affects the supply price and terms, not outage response — reliability is delivered by the utility and on-site backup systems. Facilities with critical loads should coordinate procurement with their reliability and backup-generation planning, but choosing a supplier does not change who restores power.
Health systems and portfolios
Multi-site systems are best handled as a grouped multi-location procurement, grouping electricity and gas by utility and aligning renewals across the portfolio.
Getting started
Provide 12 months of electric and gas bills for a facility (interval data helps for large campuses), and the account or system can be reviewed and priced on matched terms through the procurement process. No savings figure is promised in advance.
Frequently Asked Questions
QWhat drives energy cost at a medical facility?
Medical facilities run continuous, tightly controlled HVAC (ventilation, humidity, and temperature for patient areas and equipment), plus imaging and clinical equipment and 24/7 lighting. Natural gas typically covers space heating, domestic hot water, and sterilization. The steady, around-the-clock load makes both commodities significant.
QDoes high reliability change how a facility procures energy?
Reliability is delivered by the utility and on-site systems (backup generation, UPS), not by the supply contract — choosing a supplier does not affect outage response. Procurement focuses on the supply price and contract terms. Facilities with critical loads should still coordinate any procurement with their reliability and backup planning.
QDo health systems procure better as a portfolio?
Yes. Health systems and clinic groups with multiple Illinois sites can group accounts by utility and align renewals. Sites may span ComEd and Ameren electric and different gas utilities, so a portfolio becomes a few coordinated groups.
