Platts, part of S&P Global Energy, has launched Mexico Clean Energy Certificates (CELs) price assessment, effective July 2.
The additional assessment provides comprehensive coverage of Mexico's renewable energy certificate market and greater transparency for the growing market of compliant renewable energy certificates in Mexico.
Platts initially proposed the launch in a note published May 14 and announced a decision June 4.
CELs are Mexico's primary compliance-based renewable energy instrument, introduced to support clean energy generation and ensure that electricity suppliers and qualified users meet regulatory obligations.
The Mexico CEL assessment reflects the market value of transferable Mexican CELs intended for use in the current compliance period under the S-CEL framework. While CELs do not currently trade with an observable generation-year vintage distinction through S-CEL, market activity is often structured around annual compliance cycles and delivery expectations associated with CEL obligations established under Mexican regulation.
Therefore, the assessment focuses on the prompt bilateral market for CELs relevant to the current compliance period. It rolls to the next compliance period on May 16 every year, following the annual CEL declaration deadline established under the Mexican regulatory framework on May 15. For example, from May 16, 2027, the CELs assessment for the current year would reflect 2027.
The assessment reflects the following specifications:
| Specification | Details |
| Assessment Name | Mexico Clean Energy Certificates (CELs) |
| Symbol | AMCLA00 |
| Volume | Min 1 MWh |
| Delivery | Current-year delivery. Roll date May 16 – if price is not assessed on May 16, rollover will be on the next assessment date |
| Frequency | Weekly, every Thursday |
| Pricing Unit | $/MWh with conversions in MXN/MWh. |
| Timestamp | 3:30 pm Mexico City close |
| Holiday Calendar | Mexico holiday calendar. In case of public holiday on a Thursday, the assessment will take place on the prior working day. |
The new assessment appears in REC Daily.
