Overview
Lomar Substation is an operational electrical substation in the United States, operating at 115 kV. It plays a role in the regional power grid, supporting electricity transmission and distribution.
Lomar Substation is an operational electrical substation located in the United States, with coordinates 38.749305, -77.502953. The facility operates at a voltage of 115 kV, classifying it as a medium-voltage substation within the electrical infrastructure sector. Substations at this voltage level are typically used for subtransmission or distribution, serving local communities and industrial areas. As a substation in the United States, Lomar Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and is subject to Federal Energy Regulatory Commission (FERC) oversight for reliability standards. The facility likely adheres to NERC's Critical Infrastructure Protection (CIP) standards and may utilize IEC 61850 for substation automation, depending on its age and modernization level. The substation's location in Virginia places it within the PJM Interconnection, one of the largest regional transmission organizations in the U.S. This context underscores its role in maintaining grid stability and reliability for the surrounding area. The operational status indicates ongoing contribution to the electrical network, supporting local demand and integration of generation resources.
Environmental context
The substation is located in a region with a mix of urban and suburban development, typical of Northern Virginia. The area experiences seasonal temperature variations, which influence electricity demand for heating and cooling. Substations like Lomar are critical for grid stability, especially during peak load periods. The facility's voltage level suggests it serves a local distribution network, with potential environmental considerations related to electromagnetic fields and land use, though these are managed through standard siting and operational practices.
Frequently asked questions
