4 Introduction This report constitutes the Maryland Public Service Commission s Ten-Year Plan ( ) of Electric Companies in Maryland. The Ten-Year Plan is submitted annually by the Commission to the Secretary of the Department of Natural Resources in compliance with of the Public Utilities Article, Annotated Code of Maryland. It is a compilation of data relevant to the long-range plans of Maryland's electric companies. Maryland is geographically divided into thirteen electric utility service territories. The four largest are investor-owned utilities ( IOUs ), four are electric cooperatives (two of which serve mainly rural areas of Maryland), and five are electric municipal operations. 1 PJM sub-regions, known as zones, generally correspond with the IOU service territories. PJM zones for three of the four IOUs traverse state boundaries and extend into other jurisdictions. Figure 1 below provides a geographic picture of the utilities service territories. 2 Figure 2 depicts the PJM forecast zones which comprise Maryland. Figure 1: Maryland Utilities and their Service Territories in Maryland 3 1 The Commission regulates all Maryland public service companies, as defined by 1-101(x) of the Public Utilities Article, Annotated Code of Maryland. 2 PE no longer uses its doing business name of Allegheny Power and any references within the Ten- Year Plan to Allegheny Power is inadvertent and should be read as referencing PE. 3 Cumulative Environmental Impact Report 16, Maryland Department of Natural Resources, Figure 2-12, (last updated February 20, 2012). 1
