International Paper Mansfield Substation - CLECO 138 kV Substation in Louisiana, USA

International Paper Mansfield Substation is a 138 kV electrical substation located in Mansfield, Louisiana, United States. Owned and operated by CLECO, this facility is part of the transmission infrastructure that supplies power to the International Paper mill and the surrounding region. As a substation operating at 138 kV, it falls within the sub-transmission voltage range typical for industrial and distribution-level service in the US grid. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. CLECO, as a utility in the Louisiana market, must comply with these standards to ensure grid stability and safety. The 138 kV voltage level is commonly used for industrial customers and as a step-down from higher transmission voltages. This substation plays a critical role in delivering reliable electricity to the International Paper facility, one of the largest paper and packaging manufacturers globally. Its location in rural Louisiana supports both industrial operations and local community power needs. Its operational status indicates ongoing service to the regional grid.

The substation is located in a rural area of Louisiana, near the International Paper mill. The local environment includes forested and agricultural land, typical of the region. Substations at this voltage level have minimal direct environmental impact, but their role in powering industrial facilities like paper mills can influence local air and water quality through the mill's operations. The substation's proximity to the mill reduces transmission losses and supports efficient energy delivery.
