Platts to move MOC timestamp for Brazilian power assessments

Platts, part of S&P Global Energy, will change the time stamp of its Brazilian power assessments to 1630 São Paulo time, from 1600 Houston time, effective Aug. 24, 2026.

Platts first proposed to change the time stamp of its Brazilian power assessments on July 13 in a note available here. This change is intended to better align the time of assessments with liquidity observed in the market.

As of Aug. 24, bids, offers, trades and indicative values will only be considered for the assessment if received before the 1630 São Paulo time stamp. As part of this change, Platts Brazil power assessments will also follow the São Paulo holiday calendar, moving from the Houston holiday calendar. Further information can be found here: Platts pricing holiday schedule.

Platts will also utilize the associated Brazilian real/US dollar foreign exchange rate to align with the proposed updated time stamp and to align with the local market.

The impacted assessments are as follows:

The assessments can be found on the fixed pages PEA1301 and AGP1301, as well as in the Megawatt Daily and Platts Energy Trader publications.

Full details of Platts Americas Power coverage can be found in the Specification Guide.
