(a) General Requirements. To increase the transparency
of the ERCOT-administered markets, ERCOT must post the information
required in this section at a publicly accessible location on its
website. In no event will ERCOT disclose competitively sensitive consumption
data. The information released must be made available to all market
participants.
(1) ERCOT will post the following information in aggregated
form, for each settlement interval and for each area where available,
two calendar days after the day for which the information is accumulated:
(A) quantities and prices of offers for energy and
each type of ancillary capacity service, in the form of supply curves;
(B) self-arranged energy and ancillary capacity services,
for each type of service;
(C) actual resource output;
(D) load and resource output for all entities that
dynamically schedule their resources;
(E) actual load; and
(F) energy bid curves, cleared energy bids, and cleared
load.
(2) ERCOT will post the following information in entity-specific
form, for each settlement interval, 60 calendar days after the day
for which the information is accumulated, except where inapplicable
or otherwise prescribed. Resource-specific offer information must
be linked to the name of the resource (or identified as a virtual
offer), the name of the entity submitting the information, and the
name of the entity controlling the resource. If there are multiple
offers for the resource, ERCOT must post the specified information
for each offer for the resource, including the name of the entity
submitting the offer and the name of the entity controlling the resource.
ERCOT will use §25.502(d) of this title (relating to Pricing
Safeguards in Markets Operated by the Electric Reliability Council
of Texas) to determine the control of a resource and must include
this information in its market operations data system.
(A) Offer curves (prices and quantities) for each type
of ancillary service and for energy in the real time market, except
that, for the highest-priced offer selected or dispatched for each
interval on an ERCOT-wide basis, ERCOT will post the offer price and
the name of the entity submitting the offer three calendar days after
the day for which the information is accumulated.
(B) If the clearing prices for energy or any ancillary
service exceeds a calculated value that is equal to 50 times a natural
gas price index selected by ERCOT for each operating day, expressed
in dollars per megawatt-hour (MWh) or dollars per megawatt per hour,
during any interval, the portion of every market participant's price-quantity
offer pairs for balancing energy service and each other ancillary
service that is at or above a calculated value that is equal to 50
times a natural gas price index selected by ERCOT for each operating
day, expressed in dollars per megawatt-hour (MWh) or dollars per megawatt
per hour, for that service and that interval must be posted seven
calendar days after the day for which the offer is submitted.
(C) Other resource-specific information, as well as
self-arranged energy and ancillary capacity services, and actual resource
output, for each type of service and for each resource at each settlement
point.
(D) The load and generation resource output, for each
entity that dynamically schedules its resources.
(E) For each hour, transmission flows, voltages, transformer
flows, voltages and tap positions (i.e., State Estimator data). Notwithstanding
the provisions of this subparagraph and the provisions of subparagraphs
(A) through (D) of this paragraph, ERCOT must release relevant State
Estimator data earlier than 60 days after the day for which the information
is accumulated if, in its sole discretion, it determines the release
is necessary to provide a complete and timely explanation and analysis
of unexpected market operations and results or system events, including
but not limited to pricing anomalies, recurring transmission congestion,
and system disturbances. ERCOT's release of data in this event must
be limited to intervals associated with the unexpected market or system
event as determined by ERCOT. The data released must be made available
simultaneously to all market participants.
(b) Development and implementation. ERCOT must use
a stakeholder process, in consultation with commission staff, to develop
and implement rules that comply with this section. Nothing in this
section prevents the commission from taking actions necessary to protect
the public interest, including actions that are otherwise inconsistent
with the other provisions in this section.
