The REC Data Access Schedule sets out the approach to provision of market data via the Electricity Enquiry Service (EES). This will be extended to cover the Gas Enquiry Service at Central Switching Service (CSS) go live. This schedule categorises EES users e.g. Energy Suppliers, Distribution Network Operators (DNOs), Third Party Intermediaries and sets out the principle that a defined set of data will be accessible to EES Users depending on their category. The specific data items accessible for each EES User Category are set out in the Data Access Matrix. This approach differs from the previous arrangements under the Master Registration Agreement (MRA) where data accessible by certain types of user would be agreed on a case by case basis, leading to differences between data accessed by different organisations within the same EES User Category. Following the transfer of governance from the MRA to REC, an activity has been initiated to review the historic Data Access Agreements. This has identified areas where data access is not being governed in accordance with the REC approach i.e. there is no clear list of data items accessible to each EES User Category and there are potentially some instances where restrictions placed on accessibility of data are not justified.
