OMIE confirms go-live of 96-round quarter-hourly continuous intraday market in MIBEL

This press release restates the same 23 September 2026 go-live already captured in the prior event: OMIE has moved the MIBEL continuous intraday market from 24 hourly gate closures to 96 quarter-hourly gate closures, with trading possible up to 60 minutes before delivery. No new facts, dates, or design details beyond what was previously recorded are present; this source confirms the go-live actually occurred as scheduled.

The confirmation matters because it verifies that the structural redesign of MIBEL's intraday microstructure has been executed on schedule, coordinated with REE and REN, rather than being delayed or altered. This operational confirmation reduces implementation risk uncertainty and signals the market is now live under the new 96-round scheme, a prerequisite for any subsequent assessment of liquidity or price-formation impacts.

Because this document is the same press release that originally established the prior event record, there is no incremental design information to analyze beyond reaffirming completion. Analytically, the fact that OMIE issued this confirmation on the go-live date itself, referencing the extensive prior agent-preparation process (seminars, test scenarios, rule change proposals), suggests the transition proceeded without an announced disruption—though the source contains no operational performance data (spreads, volumes, liquidity by quarter-hour) that would allow assessment of early market functioning. Future updates should focus on whether liquidity fragmentation across the four-fold increase in order books materializes as a transitional friction, as anticipated in the prior analysis.
