Lilly Technical Center Diesel Power Plant, Indianapolis, Indiana | United States

Lilly Technical Center is a diesel power plant located in Indianapolis, Indiana, United States. With a capacity of 6 MW, it is a small-scale facility primarily used for backup or peak power generation. The plant is owned by Eli Lilly and Company, a global pharmaceutical company, and supports the energy needs of its technical center. Diesel power plants like this one operate using internal combustion engines fueled by oil. They are typically employed for emergency backup, peak shaving, or remote power applications. In the United States, such facilities are subject to EPA regulations under the Clean Air Act, including National Emission Standards for Hazardous Air Pollutants (NESHAP) for reciprocating internal combustion engines (RICE). The plant's small capacity and intermittent operation likely place it in a lower regulatory tier. The facility plays a critical role in ensuring reliable power for Eli Lilly's research and development activities. Its location in Indianapolis places it within a major urban and industrial area, where grid reliability is essential. The plant's diesel engines can start quickly to provide power during grid outages, supporting continuous operations at the technical center.

Diesel power plants emit pollutants such as nitrogen oxides (NOx), particulate matter (PM), and carbon dioxide (CO2). The Lilly Technical Center's location in an urban area means its emissions could affect local air quality, though its small capacity and likely infrequent operation reduce overall impact. The plant is subject to EPA's RICE NESHAP and New Source Performance Standards (NSPS), which require emission controls and operational limits. Nearby residential and commercial areas may experience localized air quality impacts during operation.
