Current Status

With Authority
Awaiting Implementation


P329 proposes to align the BSC and Balancing Mechanism Reporting Service (BMRS) with the Regulation on Wholesale Energy Markets Integrity and Transparency (REMIT) common schemas for inside information web feeds, required by the Agency for the Cooperation of Energy Regulators (ACER).

To achieve this, the REMIT inside information data submitted by participants and reported by the BMRS will need to cover the output requirements of ACER. In addition to the ACER requirements, P329 would enable the submission of outage profile information to BMRS.

BSC Parties will be ultimately responsible for both accuracy and timeliness of their REMIT messages.
