The latest installment of our North American database US_Canada_DB_2017_v2 has been posted.

Database updates are available either directly through the model by going to Help > Updates > Check for Database Updates or via download from our Support website. Data updates are offered throughout the year and we strive to make sure our customers get current updates as data becomes available.

This update includes a major Resource table restructuring that disaggregates all of the U.S. resources and provides many advantages to our clients moving forward. With units broken out to their finest generator granularity, mapping to other specific data sources that clients may be using for analysis becomes much easier. Also, this enables our resources to have a one to one relationship to EIA data, which can be used to quickly access other parts of their robust data sets. Coupled with the new Base Resource ID logic (discussed further in the User Guide and Release Notes) this release offers resource granularity where needed with no hindrance to runtime. In many systems, the runtime actually improves!

Below is a high-level bulleted list of what is included in the database and in the data package.

The database within this data package includes:
  • A resources table that has had all its U.S. resources disaggregated. The new table has been named "Resources Disaggregated" to distinguish it from previous tables.
  • An East Interconnect focused update that includes resource and demand updates.
  • A fuel update for natural gas, jet fuel, kerosene, and a coal update that includes a new, tiered approach described further in the Release Notes.
  • Updates to carbon price and planning reserve requirements.
  • New MST, RMT and Capacity Price tables across North America.
  • Other incremental updates across many regions.

Beyond the database, the data package itself includes:
  • Release Notes for US_Canada_DB_2017_v2.pdf - A very robust set of release notes covering all the major changes included in this database update.
  • Resources_Disaggregated_User_Guide.pdf - A user guide to assist with understanding and incorporating new database.
  • Change_Set_Conversion.xlsm - An Excel file with macros to assist in applying client change sets to the new disaggregated structure.
  • Disaggregated_ID_Key.xlsx - An Excel file that can be used as a descriptive ID key to go from the old Resources table IDs to the new Resources Disaggregated ones.
  • Also a dbCompare file, updated project files, and other documents and files that are contained in a typical release.

Some important items to note that are specific to this update:
  • The Resources table has been temporarily renamed Resources Disaggregated to help curb loss of data with client change sets. We will eventually rename and deliver this table as "Resources" in a future release.
  • This database contains significant restructuring to the Resources table. Change sets built using any Resources tables delivered by EPIS prior to US_Canada_Database_2017_v2.xdb will most likely not work with the new Resources Disaggregated table, but we have provided tools to help you convert them for use in the new table. As always, EPIS strongly encourages doing a complete back-up of existing databases, project files (especially if they contain change sets), and standalone change Set Files (.csf) to avoid losing current work.
  • This database takes advantage of the Base Resource ID logic. The Base Resource ID logic is only available in version 12.3.1001 of the model or later. The Resources Disaggregated table can be used with older versions of the model, but upgrading to version 12.3.1001 or later will greatly reduce runtime when using the new table.

We welcome you to download the data package and use the tools and guides we provide for a smooth incorporation of it into your modeling practices.

EPIS Releases New Version of AURORAxmp

Version 12.3 introduces significant enhancements

Las Vegas, Nevada – April 25, 2017 (GLOBE NEWSWIRE) -- EPIS (, the market leader in power market simulation, forecasting and analysis, announced the release of version 12.3 of its AURORAxmp software at the Platts Global Power Markets™ Conference. The latest version boasts a number of enhancements to storage logic, ancillary services, long-term logic, improved RPS modeling and nodal capabilities.

AURORAxmp 12.3 further solidifies its position as the most valuable power market forecasting and analysis software on the market today. It is fast, easy to use, and transparent. Upgrades in the new version include:
  • Enhanced Storage Logic—improved ability to model the intricacies of renewable and storage integration, electric vehicles, and other technologies.
  • Ancillary Services Enhancements—significant enhancements, including sub-hourly dispatch and use in nodal studies, and improved MW reporting for simultaneous contributions to multiple products.
  • Improved RPS Modeling—offers new option to identify resources not eligible to set capacity prices-- especially useful when modeling RPS policies where renewable resources must be built but cannot participate in capacity markets. Also, RPS constraints can now be input as a percentage of demand or MWh value, giving more flexibility to specifying RPS targets over time.
  • Long-Term (LT) Capacity Expansion Logic Enhancements—now have the option to change dispatch-hour sampling dynamically—accelerating studies, but still providing detail on final production run.
  • New LT Constraint Types—including capacity and energy max limits, which provide more flexibility for build decisions to targets in LT studies.
  • New LT Reporting Option—new build report output table making it helpful to quickly see which constraints were binding (min, max by technology/fuel/area).
  • Nodal SCUC—version 12.3 also includes an exciting new option to run a full security constrained unit commitment (SCUC). The mixed-integer program that performs the commitment decisions, now accounts for nodal constraints, including branch, corridor, and contingency constraints. The new SCUC ability is in addition to a new, proprietary solving method that significantly speeds nodal analysis.

AURORAxmp v.12.3 is further enhanced by the proven and calibrated databases that either come with the license or as an add-on, including: U.S.-Canada, Europe or Mexico. The calibrated datasets simplify meaningful forecasting. All AURORAxmp databases include a base-case 25-year power price forecast and generator capacity expansion and retirement plan. The sources and procedures used to update the data are thoroughly documented. Updates to the databases are provided under the annual AURORAxmp license.

For the past 20 years, AURORAxmp has had a reputation for being best-in-class, with unmatched support. Version 12.3 further establishes its position as the leader in power market forecasting and analysis.
