NOTICE DATE: May 4, 2010
NOTICE TYPE: M-A042710-02 PRR
SHORT DESCRIPTION: Follow-up to WGR Turbine SCADA Implementation of
PRR830
INTENDED AUDIENCE: QSEs Representing WGRs and Resource Entities
DAY AFFECTED: June 1, 2010
LONG
DESCRIPTION: This Notice will provide additional information regarding
implementation of Wind-powered Generation Resource (WGR) telemetry for turbine
availability.
Protocol
Section 6.5.7.1(10) requires WGRs to provide the following Real-Time SCADA
points to ERCOT via the WGR’s Qualified Scheduling Entity (QSE) ICCP data
link:
·
The
number of wind turbines that are available for real power and/or Reactive Power
injection into the ERCOT Transmission Grid
·
The
number of wind turbines that are not able to communicate and whose status is
unknown; and
·
The
number of wind turbines out of service and not available for operation.
WGRs are to comply with the
requirements of paragraph (10) by no later than June 1, 2010.
Similar to the implementation of MET
data telemetry, ERCOT prefers that these new data points be added to the Nodal
ICCP telemetry set. This will forego having this data sent across both zonal
and Nodal data links. For affected QSEs who will not be able to provide this
data over Nodal ICCP by June 1, ERCOT requests the QSE provide an
implementation plan. This plan may be sent to your ERCOT Account Manager.
Example ICCP format is as follows:
Wind Turbine Info |
WT |
No. of Turbines Online |
NTON |
INDX |
DiscreteQ |
ACMEWT_WNDSUB_UNIT1_NTON |
No. of Turbines Offline |
NTOF |
INDX |
DiscreteQ |
ACMEWT_WNDSUB_UNIT1_NTOF |
||
No. of Turbines Unknown |
NTUN |
INDX |
DiscreteQ |
ACMEWT_WNDSUB_UNIT1_NTUN |
ERCOT will add these new telemetry requirements
to the Nodal ICCP Handbook and other related documentation as applicable.
ACTION REQUIRED: All WGRs must begin sending the required Real-Time
SCADA points via ICCP, at a frequency of 10 seconds, no later than June 1,
2010. SCADA points are to be sent via the WGR’s QSE ICCP data link to
ERCOT.
If the WGR’s QSE is not currently able to provide
this data through ICCP, the QSE should contact its ERCOT Account Manager to
develop a solution.

Subject: M-A042710-01 WGR Turbine SCADA Implementation of PRR830
NOTICE DATE: April 27, 2010
NOTICE TYPE: M-A042710-01 PRR
SHORT DESCRIPTION: WGR Turbine SCADA Implementation of PRR830
INTENDED AUDIENCE: QSEs Representing WGRs and Resource Entities
DAY AFFECTED: June 1, 2010
LONG
DESCRIPTION: Protocol
Revision Request (PRR830), Reactive Power Capability Requirement, was approved
by the ERCOT Board of Directors on November 17, 2009. Although PRR830 has been
appealed by certain Entities representing Wind-powered Generation Resources
(WGRs) to the Public Utility Commission of Texas (pending PUC Docket No.
37817), only the December 31, 2010, deadline for compliance with the Reactive
Power capability requirement for existing WGRs has been suspended while
the PUC docket is pending. See Order No. 6 in Docket No. 37817.
The remaining portions of PRR830 were effective on December 1, 2009.
As such, this Notice is to remind WGRs
of Protocol Section 6.5.7.1(10) which requires WGRs to provide a Real-Time
SCADA point that communicates to ERCOT the number of wind turbines that are
available for real power and/or Reactive Power injection into the ERCOT
Transmission Grid. WGRs must also provide two (2) other Real-Time SCADA points
that communicate to ERCOT the following:
(a)
The number of wind turbines that are not able to communicate and whose status
is unknown; and
(b)
The number of wind turbines out of service and not available for operation.
WGRs must comply with the requirements
of paragraph (10) by no later than June 1, 2010.
ACTION REQUIRED: All WGRs must begin sending the required Real-Time
SCADA points via ICCP no later than June 1, 2010. SCADA points are to be sent
via the WGR’s Qualified Scheduling Entity (QSE) ICCP data link to ERCOT.
