Innovative Technology for Reliable and Secure OT Communications


Our Mission

We actively develop and support measures to improve interoperability and cybersecurity in DNP systems by developing technologies and standards, implementing a conformance program, and providing education to the industry.


Activities of the Users Group

DNP3 has grown to be the most widely used protocol for electric transmission and distribution communications in North America and other regions of the world, and is a named standard for DER communications. DNP3 is also broadly adopted in adjacent industries such as water / wastewater, transportation and the oil and gas industry. 

The DNP Users Group (DNP-UG) owns and maintains DNP3 and supports our user community and the industry by enhancing and promoting DNP3 (Distributed Network Protocol), also known as IEEE Std. 1815TM. Our members include utilities, suppliers, consultants, and individuals (including students). Many of our initiatives support greater interoperability between supplier’s products and systems and/or enhance cyber security. On-going refinements also add new features and time-saving capabilities which are then included in the next update of IEEE 1815. Our growing library of Standards, Application Notes, Guides, Security Notices, and Technical Bulletins provide essential information for our members. The leadership team and technical team members provide periodic educational opportunities including tutorials, white papers, and conference presentations. Our Conformance Certification Program manages the Conformance Test Review process and publishes conformance certificates which are publicly posted. The DNP-UG is governed by our Board of Directors in accordance with our bylaws. The technical teams are involved with four different groups as follows:

  • Technical Committee
  • Cybersecurity Task Force
  • Test Management Committee
  • Test Procedure Committee.


Recent and current developments include new:

  • Update to the IEEE Std. 1815TM standard.
  • DER communications standard – IEEE 1815.2TM (draft) – joint effort with MESA.
  • Secure Authentication v6 (SAv6).
  • Authorization Management Protocol (AMP).
  • Test procedures.
  • Device profile guide.
  • Expanded Conformance Certification Program (CCP).
