Energy-as-a-Service Contracts Are Coming to Indiana Manufacturers, and the Math Deserves Scrutiny

The energy service market is projected to grow from $42.7 billion in 2025 to roughly $101.2 billion by 2035. Providers like ABB, Ameresco, Enfra, and Siemens are pitching models where they own and maintain your upgraded boilers, chillers, and controls, and you pay a subscription or share the savings rather than writing a capital check. Enfra's 30-year contract with Rochester Regional Health is projected to deliver roughly $6.9 million in first-year utility cost savings, and that's the type of deal now being positioned for large industrial and institutional customers in Indiana.

The model itself isn't the problem. The problem is the math. TEG has personally audited large guaranteed savings projects from firms exactly like these and found significant misrepresentation of before-and-after savings, in models so complex the customer had no practical way to verify the numbers independently. With contract terms stretching 10 to 30 years and dollar amounts in the millions, stipulated savings on paper are not the same as savings on your bill. Before any energy as a service proposal moves forward at your facility, you need an independent, revenue-grade monitoring layer in place and someone on your side who can audit contract language for measured and verified savings, not just review what the vendor's spreadsheet says.
