Purpose NV Energy develops powerflow and dynamic models in collaboration with the Western Electricity
Coordinating Council (WECC), its assigned Electric Reliability Organization (ERO) and Regional
Compliance Enforcement Authority. These models are used for Transmission-level analysis of the power
system by NV Energy and its neighboring utilities.
NV Energy as a NERC registered Planning Coordinator (PC), and its Transmission Planners (TPs) have
jointly established a set of common data requirements and reporting procedures for submitting steady
state, dynamic, and short circuit modeling data as set forth in this document.1
The purpose of this document is to outline NV Energy’s data reporting requirements and procedures
necessary to facilitate accurate modeling of the transmission system in a manner compliant with NERC
MOD standards2.
Pursuant to NERC requirements3, this document and the corresponding attachments are hosted at the
following online location:
http://www.oatioasis.com/nevp/
“Transmission Planning Policy” -> “MOD-026-027-032 Policy”
Any questions and corresponding data communications shall be submitted to NV Energy’s Transmission
Planning Department via the following two email addresses:
To: [email protected] CC: [email protected]
The first email address is for communications with NV Energy, the second is required for record keeping
purposes.

Overview WECC compiles Western Interconnection models on a regular basis for use in transmission analysis. As a
member of WECC, NV Energy is required to prepare modeling data for WECC for each compilation. NV
Energy’s data submittal timelines and schedules are determined on a yearly basis by WECC. For these
submittals, it is necessary for NV Energy to gather accurate, up-to-date information from the multiple
data owners within its Balancing Authority Area. On an annual basis, NV Energy sends requests to these
data owners for information necessary to support the creation of interconnection-wide cases.
These data owners include:
Transmission Owners (TO)
Load Serving Entities (LSE)
Generator Owners (GO)
Data format and submittal procedures are described on the following pages, and differ for each type of
Data Owner.
NV Energy has two processes used to collaborate with WECC and produce models of the transmission
network:
1. Data Collection and Aggregation
2. Model Development for WECC Requested Model Submittals
These processes function in parallel.

Energy as outlined in this document.
NERC
o Individual generating unit greater than 75 MVA (gross nameplate rating).
o Individual generating plant consisting of multiple generating units that are directly
connected at a common BES bus with total generation greater than 75 MVA (gross
aggregate nameplate rating).
o A technically justified unit that meets NERC registry criteria but is not otherwise included
in the above Applicability sections and is requested by the Transmission Planner.
WECC
o Generation Facilities connected at 60 kV or higher voltage with 10 MVA or larger individual
capacity or 20 MVA aggregate
Timeline Per WECC & NERC standards, Generator Owners who meet the above requirements shall perform
testing:

Model Development
Data Format10 NV Energy’s powerflow and dynamic models are maintained in GE PSLF format. Data requirements are
specified by WECC, and any data submitted by the Data Owner(s) to WECC through NV Energy must
conform to all specifications required by WECC. Please refer to the WECC Data Preparation Manual. Any
other Data Submittal Format requirements are outlined in this document.
Level of Detail11 Where necessary, NV Energy’s models are more detailed than required by WECC for purposes of
accuracy and/or improving the level of usefulness of the data. NV Energy generally maintains models
with the following level of detail for Power Flow cases:
All equipment 55kV and above is modeled
Generators are modeled down to the low-side of the GSU
Loads are modeled as lump sums on the transmission busses. In cases where SCADA measurements
are taken on the low-side of the Distribution Transformer(s), NV Energy may model down to the
distribution bus.
Case Types12 MOD-032-1 requires data to be submitted at least once every 13 months. WECC releases a case-building
schedule on an annual basis. The schedule includes case types to be modeled, and tentative due dates.
NV Energy collaborates with WECC to submit all requested cases.
Transmission Projects Transmission projects with high certainty (contracts, for example) are modeled by NV Energy. Which
projects are modeled in WECC cases is at the discretion of NV Energy’s Transmission Planning
department.
Load & Generation Models submitted by NV Energy to WECC have total BA load levels which match the latest forecast
numbers to within +1% to -5%. If NV Energy’s existing generation is not sufficient to meet the forecasted
load levels, NV Energy will model minimal levels of generation proposed in the NPC & SPPC Triennial
Integrated Resource Plan (IRP) filing. Prior to scaling loads, a snapshot of NV Energy’s loads for the
season are applied to the case.
Short Circuit Data MOD-032-1 requires that short circuit data should be shared openly between applicable NERC functional
entities. This data should be provided upon request by applicable NERC functional entities in the data
owners preferred software format. NV Energy will address short circuit data gathering on a case-by-case

basis via Email requests. Responses may be submitted to the email addresses at the beginning of this
document. This data will be compiled and provided to WECC upon request.13
WECC Data Submittal Methodology14 Two individuals are assigned the role of “Area Coordinator” to ensure there is a primary and a backup.
When formal requests are received by WECC15, the deadlines are added to both Area Coordinator’s
Outlook calendars with reminders to ensure no data requests are missed. Both individuals are fully
trained on creating WECC cases from scratch, including:
How to properly maintain the “Master.sav” case and Master Project EPC files
o Master.sav represents the existing system
o Master Project EPCs represent future projects with some level of certainty
How to apply a load distribution from a seasonal snapshot to a case, then scale the loads to match
a forecast
How to dispatch generation in an economic fashion
How to coordinate interchanges with neighboring areas
How to adjust shunts and generator voltage set-points to properly regulate voltage
How to run SSTools contingency analysis on a case and correct case-building errors prior to
submittal
How to handle case review and comments
WECC cases are submitted to:
13 At present, there is no formal process in place for submitting short circuit data to WECC. Short circuit data will be provided to WECC and other MOD-032 applicable entities upon request. 14 MOD-032-1 R4 15 MOD-032-1 R1.2.4

Sub-Synchronous Resonance (SSR) & Control Interaction (SSCI) SSR & SSCI are phenomena, usually associated with series capacitors, of low frequency oscillations in the
power system. SSR may cause severe physical damage to a generator’s shaft; SSCI may interfere with
proper operation of control schemes (including power inverters). Performing analysis of SSR & SSCI
requires two types of data: Machine Torsional Data, and SSCI Data. These both may be requested
pursuant to MOD-032-1 R1 (see “Dynamics”, item 10, “Other Information”). Such a request will typically
be driven by generation locations electrically close to series capacitors, and shall be provided to NV
Energy upon request. An example of Machine Torsional Data is shown below for reference.
