Missing Data: DAM Settlement Point Prices (np4-190-cd) & DAM Clearing Price for AS (np4-188-cd) on 2026-03-07

[mansimii]

Hi,

Data for 2026-03-07 appears to be absent from the ERCOT Public API for two reports:

• NP4-190-CD – DAM Settlement Point Prices (dam_stlmnt_pnt_prices)
• NP4-188-CD – DAM Clearing Price for Ancillary Services

I have been trying to query the ERCOT API for the same and no records back in response.
API queries return totalRecords: 0 for this date, while identical queries for dates immediately before and after return data as expected. This issue is also reproducible via the ERCOT Data Access Portal GUI, where no posting entry exists for 2026-03-07, suggesting the root cause is a missing upstream posting rather than an API defect.

I get the following response back from my API call:

{'_meta': {'totalRecords': 0, 'pageSize': 100000, 'totalPages': 0, 'currentPage': 0, 'query': {'parameterCount': 2, 'parameters': {'deliveryDateFrom': '2026-03-07', 'deliveryDateTo': '2026-03-07'}, 'sortedBy': 'deliveryDate: DESC,hourEnding: ASC,settlementPoint: ASC'}}, 'report': {'reportName': 'dam_stlmnt_pnt_prices', 'reportDisplayName': 'DAM Settlement Point Prices', 'reportId': '12331', 'reportEMIL': 'NP4-190-CD', 'downloadLimit': 2000000}, 'fields': [{'name': 'deliveryDate', 'label': 'Delivery Date', 'cardinality': 1, 'dataType': 'DATE', 'searchable': True, 'sortable': True, 'hasRange': True}, {'name': 'hourEnding', 'label': 'Hour Ending', 'cardinality': 2, 'dataType': 'VARCHAR', 'searchable': True, 'sortable': True, 'hasRange': False}, {'name': 'settlementPoint', 'label': 'Settlement Point', 'cardinality': 3, 'dataType': 'VARCHAR', 'searchable': True, 'sortable': True, 'hasRange': False}, {'name': 'settlementPointPrice', 'label': 'Settlement Point Price', 'cardinality': 4, 'dataType': 'DOUBLE', 'searchable': True, 'sortable': True, 'hasRange': True}, {'name': 'DSTFlag', 'label': 'DST Flag', 'cardinality': 5, 'dataType': 'BOOLEAN', 'searchable': True, 'sortable': True, 'hasRange': False}], 'data': [], '_links': {'self': {'href': 'https://api.ercot.com/api/public-reports/np4-190-cd/dam_stlmnt_pnt_prices'}, 'parent': {'href': '[https://api.ercot.com/api/public-reports/np4-190-cd'}}}

My subscription key is still valid. I am able to download data from various other stores.

Questions:

1. Was there a known posting delay or system issue on 2026-03-07 that would explain the missing data?
2. Is there an alternative endpoint or mechanism to retrieve this data while the issue is unresolved?
3. What is the expected timeline for the data to be backfilled or the issue resolved?

This data gap has a direct impact on order placement and monitoring workflows. Any response would be appreciated.
