Reliability & Planning

For the ODEC service area of Virginia, Maryland and Delaware, we have over 225 delivery points through 4 transmission providers: Dominion Energy, Delmarva Power, First Energy and American Electric Power.

  • We work with these transmission providers and member cooperatives to ensure the most reliable level of service possible
  • We also contract transmission service from our transmission providers by way of FERC-approved agreements under the PJM Open Access Transmission Tariff
  • By coordinating long-term planning activities with PJM and our providers, we can ensure current and future transmission systems will always meet energy needs of ODEC member co-ops

NERC Compliance

  • ODEC is also registered for NERC compliance as a Distribution Provider on behalf of our 11 members through ReliabilityFirst and SERC Corporations
  • In addition, for ODEC internal NERC compliance, we are registered as a Generation Owner and Generation Operator

FERC Standards of Conduct & OASIS

ODEC’s transmission facilities are part of the Mid-Atlantic power grid operated by PJM, a regional organization directing the operation of a transmission grid covering the Mid-Atlantic. PJM also is the tariff administrator and service provider for all transmission owners within their control area and provides all transmission service.

Information on the capacity of ODEC’s transmission systems is available at the PJM OASIS Website. Transmission customers should reserve transmission service through the PJM OASIS Website.
