Lower your ethanol plant’s carbon intensity while improving your operational economics.

As ethanol facilities evaluate their energy needs, energy and plant leaders typically face one or more of four challenges as they work to optimize their operations:
1. Resiliency

Ensure resiliency to allow for production even during long-duration outages

2. Sustainability

Meet evolving ESG and sustainability commitments of corporate leadership

3. Capex

Commit capital to upgrade infrastructure in order to increase plant capacity or maintain current production

4. Savings
Meet production cost targets by reducing the energy costs for the facility

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 plants to take control of their energy future:

  • Achieve a lower carbon intensity (CI) score and increase competitive stance in the market

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

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

  • Lower operating expenses while handling increased electric demand from added facility processes

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
  • 15-25% reduced CO2 emissions depending on location and thermal load
  • 3 to 7 point reduction in Carbon Intensity Score

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

An on-site microgrid is an investment in the future. As additional technologies and fuel sources become available, such as biogas, renewable natural gas, hydrogen, and carbon capture, they can be incorporated into the existing infrastructure.

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
