Microgrids with solar, cogeneration, and battery storage support energy resiliency, allowing hospitals to prioritize patient care even when the grid goes down.

As hospitals evaluate their energy needs, health care leaders typically face one or more of four challenges as they work to deliver the best patient care:
1. Resiliency

Ensure resiliency for operations even during long-duration outages

2. Sustainability

Meet evolving ESG and sustainability commitments of corporate leadership

3. Capex

Commit capital to upgrade infrastructure to provide consistent levels of care

4. Savings
Manage or reduce the impact of escalating costs to serve patients

Unison Energy

Unison Energy is enabling the energy transition for our customers. On-site microgrids support corporate ESG initiatives while providing resilient power — and our ESA model helps alleviate capital constraints and rising energy costs. A Unison microgrid allows hospitals to take control of their energy future:

  • Combined heat and power (CHP) provides reliable, cost-effective electricity and can operate in island mode to provide power to the hospital when the utility is down

  • Using the waste heat to offset boiler usage improves efficiency and reduces the carbon footprint of the hospital

  • Adding in solar and battery storage where possible, including in parking lots, increases renewable energy

  • Including EV charging stations for doctors and patients supports the energy transition

A Turn-Key Energy Solution

Unison Energy uses the Energy as a Service (EaaS) model to invest in facilities. We sign a long-term contract to provide electricity and thermal energy. We invest all of the capital required and handle permitting, engineering design, equipment, construction, and ongoing maintenance. We only bill for energy used by the facility.
Typically our clients see:
  • 5-15% saved on total gas and electric bills
  • 20-60% reduced CO2 emissions depending on location and thermal load
  • 60-85% system efficiency vs. 38% grid efficiency

Our scope includes on-site microgrids using CHP, solar, and battery storage, but can be expanded to include energy infrastructure upgrades such as boiler upgrades, refrigeration integration, and HVAC replacement.

An on-site microgrid is an investment in the future. As additional technologies and fuel sources become available, such as biofuels, renewable natural gas, hydrogen, and carbon capture, they can be incorporated into the existing infrastructure. Electrification of everything from vehicles to heat pumps can also be incorporated into the system.

Unison Energy as a partner:


Our team has experience permitting and building hundreds of sites, including everything from utility power plants to fuel cells to small CHP installations



Our operations team leads the industry in uptime with 24/7 staffed monitoring center, dedicated field service technicians, large inventory, and proprietary technology


Energy as a Service

Our projects stay on our balance sheet. Under the terms of our 15- to 25-year energy services agreements (ESA), our customers make no initial investment and instead make payments based on their energy usage
