Arcanum Peaking Diesel Power Plant in Ohio, United States

Arcanum Peaking is a small-scale diesel power plant located in Ohio, United States, with a capacity of 1.8 MW. Owned by American Mun Power-Ohio Inc, the facility is operational and serves as a peaking plant, providing electricity during periods of high demand. Its small capacity and diesel fuel type are typical for peaking units that operate intermittently. The plant operates under the regulatory framework of the US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated standards such as the National Ambient Air Quality Standards (NAAQS) and the Acid Rain Program. As a diesel-fired facility, it is subject to emissions limits for sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. Small diesel peakers are often older or use reciprocating engine technology. Arcanum Peaking plays a role in grid reliability by providing backup power during peak loads or emergencies. Its location in Ohio, a state with a diverse energy mix including coal, natural gas, and renewables, means it serves as a supplementary source. The facility's environmental impact is limited by its small capacity and intermittent operation, though diesel combustion produces CO2 and local air pollutants.

The plant's diesel fuel combustion emits CO2, SOx, NOx, and particulate matter, contributing to local air quality concerns. Its small capacity (1.8 MW) and peaking operation reduce overall emissions compared to baseload plants. Proximity to populated areas in Ohio may require adherence to state and federal air quality regulations, including the Clean Air Act's NAAQS for ozone and fine particulate matter.
