The Energy Market Architecture Repository (EMAR) is the home of the
Energy Code (REC). Its enabled through a Digital Navigator
platform, which can be accessed through web browser with no
installation required. You can navigate directly to this platform when
selecting the EMAR Digital REC and Data Specification tab on the left-panel.
EMAR is an online tool designed to help users better understand,
manage and apply the REC. EMAR is now available via a Digital
Navigator platform, but the previous IBM Jazz platform can still be
accessed. They contain REC
schedules (legal text); the REC Data
Specification; The Release Management tables; Code Road Map and Meter Product Data.
The EMAR platforms were built to help simplify the process of
understanding the codes, so that anyone could read into the code
and/or market scenarios and gain an understanding of a given process.
From linked terms to simplified process maps EMAR works to make
understanding the code for all, instead of the traditional approach
which relied on subject matter experts to interpret the code.
To view the EMAR visit the EMAR Dashboard. (for Portal account holders only).
Should you want to learn more, the Digital Navigator User Guide, provides an
overview of the platform and it's features. Additionally the IBM Jazz
platform is still available for users to access via the Digital
Navigator, by selecting 'IBM Jazz' from the Digital Navigator
homepage and the EMAR User Guide provides an overview of the
tool. There is also an EMAR FAQ available too.
The REC sets out the rules and regulations put in place for the
market. The EMAR contains the master version of the REC, which is
split out into a series of schedules.
The REC Schedules can be accessed via the Digital Navigator Dashboard.
The dashboard has split into a number of catrgorised sections to
help with navigation to the relevant area. Once a selection has been
made on a category, all the associated LIVE REC Schedules will be
displayed in the section to the right. Once a schedule has been
selected this will automatically open in the same browser window.

The REC Data Specification defines the Market Messages and
associated Data Items that are sent between Energy Market
Participants. The Data Specification contains messages and data items
governed under the following energy industry codes:
- The Retail Energy Code
- The Balancing and
Settlement Code (BSC)
- The Distribution, Connection and Use
of System Agreement (DCUSA); and
- The Smart Energy Code
In terms of the items governed under the REC, the data
In addition to the Market Messages and associated Data Items, the
REC Data Specification also contains gas Meter Product Data.
You can access the REC Data Specification via the EMAR Digital
Navigator and you can find out more about the Data Specification in
our REC Data Specification Guidance Document (July 2023).
The Meter Product Data is part of the REC Data Specification and
can be accessed via the Digital Navigator and IBM Jazz Platforms.
The Meter Product Data relates to gas meters and consists of:
- A zipped file containing the following spreadsheets:
- Meter Product General
- The Meter Product
- The Converter Product Table
- The Meter
Product Shadow Log
- The Converter Product Shadow
- An EMAR page containing the Response
Codes for RGMA messages.
You can find out more about the Meter Product Data in our Meter Product Data Guidance Document.
Market Scenarios are process diagrams that provide end-to-end
visualisations of the processes set out in the code
schedules. These Market Scenarios are intended to provide the user
with a high-level overview of a given process. Each Market Scenario is
linked to the code so the user can link out to the code to find more
detail should they desire.
The Market Scenarios provide a high-level overview of the owner
of activities, the order of them and what initiates these tasks.
You can access the Market Scenarios via the IBM Jazz Platform,
these maps are not currently available on the Digital Navigator Platform.
The EMAR contains not only the current version of the REC but also
all historic versions from V2.0.0 onwards and can be accessed in both
the Digital Navigator and IBM Jazz platforms.
You can identify the status of a stream from its title, which
- “Superseded” if it is a historic version of the REC
- “Live” if it is the current live version of the REC
- “Pre-release” if it is a version that is due to go-live at a
You can find out more about the REC versions, such as which
Change Proposals were implemented in each release, by viewing the REC Version History.
Within the EMAR Digital Navigator platform you can view the
version history by using the REC Version drop down which is
available on the REC Schedules landing page. This will list the Live
version of the REC and all previous superseded versions. The Digital
Navigator platform also holds a section for Pre-Release Information
which provides a list of associated REC Schedules which have had
amendments following a Change Proposal's approval. Documents
contained here will have the appropriate red-lining to easily
identify the changes that will occur.
This can also be accessed via the IBM Jazz platform through the
“Release Management” tab on the EMAR Dashboard
(only for Portal Account holders). This tab contains a table listing
the versions of REC contained within the EMAR and the REC Change
Proposals implemented in each.
