Microgrids with solar, cogeneration, and battery storage support energy resiliency, allowing supermarkets to continue serving their communities when the grid goes down.

As supermarkets evaluate their energy needs, store managers and owners typically face one or more of four challenges as they work to deliver the best customer service:
1. Resiliency

Ensure resiliency to allow operations to continue even during long-duration outages

2. Sustainability

Support energy needs associated with refrigeration and thermal

3. Capex

Reduce equipment maintenance and minimize costly equipment damage

4. Savings
Reduce operating costs by cutting the energy costs for the store

Unison Energy

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

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

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

  • Using the waste heat to support refrigeration improves efficiency and reduces the carbon footprint of the supermarket

  • Adding resiliency through a microgrid can replace the need to run and repair a backup generator

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
