Market Participant Data Access Overview


MP’s have multiple methods to access ERCOT data


External web services for machine to machine interactions


MIS for user interaction


The MP Data Access booklet has been updated (from April 07)


Substantially complete Nodal Data Services Master List


Substantially completed External Interface Specification


Substantially complete MIS External Interface Specification

There are three ways for machines to access ERCOT’s data


The External Interface Specification
describes all of the data services
available through web services







The second method is to retrieve
extracts that are also available on the
MIS through a single “getReport” web
service







The MIS External Interface Specification


Originally intended to support MIS
dashboards only


The web services are also useful for
MPs and will be exposed in exactly the
same way as the External Interface
Specification i.e. web services.

There are three ways for users to access ERCOT’s data


The MIS provides users with
a view of reports and
extracts as well as a method
for downloading the reports
and extracts




Each application displays
its user interface through
the MIS





Some applications allow for
upload and download of
data

Difference between newSchedule and Schedule


Currently all machine interfaces use the web. ERCOT will test machine
interfaces on the WAN this year but there is no published plan yet



We are adding an enhancement called chunking that will allow multi
