Timeline'
EPRI and DNP.org
(2010-2013)
• DNP3 Profile for Basic Photovoltaic Generation and Storage (AN 2011-001) - March of 2011
• DNP3 Profile for Advanced Photovoltaic Generation and Storage (AN 2013-001) - January 2013
MESA (2013-2015)
• Initial MESA-ESS profile created using concepts from EPRI and AN 2013-001 but focused on energy storage - 2013
• Refinement, reference implementation and initial field testing - 2014
• MESA-ESS TWG formed to improve and formalize the profile – March 2015
MESA, EPRI and DNP.org (2016-2017)
• MESA and EPRI agree to collaborate on a unified profile for DERs – early 2016
• MESA-ESS becomes a strict subset of the unified profile for DERs
• MESA-ESS Draft specification available - Fall 2016
• DNP3 Profile for Distributed Energy Resources to be published - 2017
