EPIS Renames Flagship Product

AURORAxmp will now be known as Aurora
Las Vegas, Nevada - September 6, 2017 - Today, at the Electric Market Forecasting Conference (EMFC), EPIS unveiled a major new release of its flagship product. Formerly known as AURORAxmp, the leading power industry forecasting and analysis tool will now be called Aurora. Aurora v13.0 is currently available in beta-release, and the official release is expected in October.

"This is a once-in-a-decade type of change," said Ben Thompson, CEO of EPIS. "While EPIS has always been known for frequent and customer-responsive development on a day-to-day basis, the company also recognizes that significant technology improvements and tectonic industry shifts require much larger investments from time to time. We've done that once again."

20 years ago, the founders of EPIS named their product Aurora to signal the dawn of a new era with the deregulation of electric power markets, and of a new tool-unlike any incumbent tools-that was expressly designed with new technology to be up to the challenge to simulate and forecast these new markets.

The current name change is intended to signal another new era, one where power systems are increasingly complex-characterized by significant penetrations of renewable generation, a wider variety of generation technologies, more operational constraints, more sophisticated load shapes, and greater policy uncertainty.
Thompson added, "The new logo reflects our core principles of being solid and dependable, of continuously improving speed and performance, and of our commitment to helping our customers be successful well into this more complex future."

    EPIS Integrates Key ITP Data from the Southwest Power Pool (SPP)


    Salt Lake City, Utah - July 20, 2017 -- EPIS (www.epis.com), the leader in power market simulation, forecasting and analysis, announced that it is now able to format and integrate additional Southwest Power Pool, Inc. (SPP) Integrated Transmission Planning (ITP) data for use with AURORA. SPP is a regional, non-profit transmission organization that manages the electric grid and energy market for a 14-state region in the central United States. Users of AURORA, who have received approval from SPP to use this additional data, will be able to stay more synchronized with the RTO's key assumptions affecting generation and transmission planning, power price forecasting and associated market analysis.

    Vetted data from SPP includes: detailed resource assumptions, including heat rates, capacities, etc.; demand growth assumptions through 2035; and SPP ITP transmission network files, including all three futures (which contain various generation expansion/retirement/CO2 policy scenarios). EPIS offers several calibrated databases with AURORA and makes it easy to integrate data from other sources.

    "AURORA users who need to incorporate data from SPP will now be able to easily do so," said Ben Thompson, CEO of EPIS. "In the past, many organizations have felt confined to a single tool from a single vendor to obtain and incorporate this critical data. Now they will have a choice."

    EPIS's expert support teams are there to guide customers through incorporating this formatted data into their current workflows for forecasting and analysis. SPP member companies and/or entities that have gone through the process of meeting their requirements to access the ITP data will be able to use it with AURORA. The ability to utilize this data alongside the included calibrated datasets, combined with AURORA's power, speed and flexibility will give users even more insight into power markets.

    As with any of AURORA's included or supplemental databases, users can expect the highest level of software integration, model control and easy data exchange. Users can easily import and overlay their own assumptions and other data sources for more powerful, customized insights.

    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 AURORA

    Version 12.3 introduces significant enhancements

    Las Vegas, Nevada – April 25, 2017 (GLOBE NEWSWIRE) -- EPIS (www.epis.com), the market leader in power market simulation, forecasting and analysis, announced the release of version 12.3 of its AURORA 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.

    AURORA 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:
