When a regional utility invited one of its largest commercial customers to participate in a voluntary demand response program, the opportunity initially appeared straightforward. During periods of peak demand or grid stress, participating facilities would reduce their reliance on grid-supplied electricity in exchange for financial incentives that support overall grid stability.

For the client—a national foodservice distribution company—the value proposition was clear. Its Iowa distribution center could maintain uninterrupted operations by shifting electrical load to its on-site backup generators while receiving compensation for its participation.

However, a significant regulatory constraint complicated the opportunity. The generators in question were permitted as emergency engines, which, under federal New Source Performance Standards and the facility’s air permits, are limited to narrowly defined non-emergency operating hours. Use of these generators for compensated demand response activities falls outside those allowances. Participation in the program would therefore reclassify the engines as non-emergency units, rendering the facility out of compliance and exposing it to potential enforcement action. Absent a clear regulatory strategy, a promising economic opportunity carried substantial compliance risk. 

To address this issue, the client engaged ADEC Innovations companies Cameron-Cole and FirstCarbon Solutions (FCS) to conduct a detailed regulatory evaluation of the generators, identify the appropriate permitting pathway to authorize non-emergency operation, and coordinate with the Iowa Department of Natural Resources to bring the facility into compliance.

Meeting the more stringent requirements associated with non-emergency engine classification required a comprehensive technical solution. Cameron-Cole implemented emissions control upgrades, including the installation of catalytic oxidizers, and deployed Continuous Emissions Monitoring Systems (CEMS) for each generator. These systems were integrated with cellular-based telemetry infrastructure—comprising VPN-enabled routers, antennas, and temperature and pressure sensors—enabling secure, real-time remote monitoring and data access.

In parallel, Cameron-Cole established a structured monthly monitoring and data review program, while FCS partnered with the client to prepare and submit annual air compliance reports to the state regulator.

As a result, the facility now participates in the voluntary demand response program in full compliance with applicable air quality regulations, supported by robust monitoring, documentation, and reporting systems. Even after accounting for capital investments, permitting efforts, and ongoing compliance activities, the financial returns generated through program participation substantially exceed the cost of implementation—transforming a potentially high-risk initiative into a sustainable and compliant source of operational value.
