Joint RA/IRP Modeling Datasets   

This page lists unified modeling input datasets and scenarios used by Energy Division to model the electric and gas system.  The datasets are fundamental inputs to Energy Division modeling and other analytical work products.

Modeling Input Datasets 

Regional Breakdown of WECC for modeling purposes

A region in the model generally represents a Balancing Authority Area (or a large portion of a BAA) within the Western Interconnect (referred to as the "WECC" region or area for short). Multiple modeling inputs correspond to a particular BAA or portion of a BAA in WECC. For purposes of Energy Division modeling, BAA areas of WECC are aggregated and grouped into 24 total regions, 8 inside California and 16 external to California. A table listing those regions is below.

Load Shapes

Each link below opens a file containing hourly load for each region included in the zonal production cost model used by Energy Division, the SERVM model developed by Astrape Consulting.  A region in the model generally represents a Balancing Authority Area (or a large portion of a BAA) within the Western Interconnect (referred to as the “WECC” region or area for short).  The load shapes in each file are scaled to a particular study year, based on the California Energy Commission’s adopted 2015 IEPR demand forecast for 2016-2026. 

Each Excel file below contains one sheet, with columns that correspond to each BAA or portion of a BAA (25 total) included in the SERVM model of the WECC.

Hourly Electricity Consumption Shapes Each link below opens a file containing hourly load for each region included in the zonal production cost model (PCM) used by Energy Division. The load shapes supplied for each  particular study year represent hourly weather shapes from 1980 through 2014, each stretched to the particular consumption peak and total energy consumption levels forecast by the California Energy Commission (CEC)'s adopted 2017 IEPR demand forecast for 2018-2030. 

Each column contains 35 years of hourly load (representing weather from 1980 to 2014) each scaled to the peak and total energy forecasted for the indicated study year.  Each year uses the 1990 calendar, meaning the first day of the year is a Monday, and all holidays and weekends correspond to 1990 dates. These profiles were generated using a weather normalization process described in the 2018 Unified Inputs and Assumptions Document.

 

50% RPS Default and 42 MMT Core portfolios from IRP Reference System Plan

The files linked below are workbooks that map the aggregated resource types in the RESOLVE model to available unit-level information. Unit-level information is generally available for baseline resources and coarse geographic information is associated with new (generic) resources.

 

Transmission-level Busbar Information

The allocation of new renewables included in the RESOLVE model's 50% RPS Default Core case and 42 MMT Core case to busbar are provided by the CEC's siting department.  That information is linked here: [link from the CEC coming soon].

For the purpose of mapping to busbar, the locations of energy storage procured to date are provided here: Combined IOU Storage Procurement 2017 Update Public

Guidance on allocating other resource types to busbar is provided in the 2018 Unified Inputs and Assumptions Document.

 

Intermittent Generation Profiles

Each link below opens a .zip file that contains hourly electricity production for the generators forecasted to be operating in the target study year organized by region included in the zonal production cost model used by Energy Division.  The hourly generation values (MW) match the installed capacity online (capmax) in the intended study year.  Resources that are not online in any given study year will have 0 generation in each hour.  The portfolio of intermittent resources online in any given study year derives from the IRP Reference System Plan 42 MMT Core portfolio adopted in February 2018.

Each row represents one resource and resources are grouped together by region.  Each tab represents one historical weather year from 1980 through 2014 normalized to the average of all years.[Note: these are very large files and the range of historical weather years are separated into two files to manage file size.]

 Other WECC-wide datasets

The files linked below include other important assumptions and inputs typically needed for modeling the WECC area with hourly detail in a production cost modeling environment.

  • Fuel Price Curves are based on 2017 IEPR NAMGas model and other PCM inputs provided by the CEC.
