PowerSimm Editor 4.1

We are excited to announce the release of PowerSimm Editor 4.1. This new release of PowerSimm is a major upgrade from previous versions, involving significant improvements on the user interface functionality, menu contents and layouts, new validation rules for notifying users of errant inputs or configuration, and remediation of existing bugs. This new UI makes substantive strides to improve the software usability and error trapping of problematic data or configurations. PowerSimm 4.1 also incorporates, for the first time, a user interface for Credit Manager, our enhanced analysis tool for credit exposure.

A lot of valuable feedback from client users and our analysts went into the development of this new release. Our main goal was to provide users a more integrated and intuitive editing/execution environment. Diligent validation and QA testing were performed on this new release by experienced IT and Services analysts to ensure error-free functionality of various components.

Major highlights from the new version of PowerSimm™ are given below. More detailed lists of enhancements, new validation rules, and bug fixes are provided in Appendices 1 through 3 at the end.

Updated Look with a New Menu System – The main editor now features a leaner UI theme inspired by Windows 8 Metro where icons for the most commonly used editors are tiled in meaningful groupings. The menu system of PowerSimm™ has been significantly changed with this release. All previous menu functionality is still present, but has been organized in a more intuitive form.

1

Tabbed Windows – In a form similar to web browsers but placed at the bottom of the frame, the newly-featured windows tabs allow the user to focus on, organize, and close work windows with more ease.

2

Backstage Menu – Also new in this version is what is termed a “backstage” menu section, accessible by clicking on the gear icon in the upper left corner of the main editor. The backstage menu hosts the configuration and administrative functions of the main editor.

3

Completely Rebuilt Generation Editor – The generation editor was rebuilt to improve its usability by grouping the types of configuration data into several screens: Resource Variables, Scheduled Outages, and Historical Input. Additional features include an added end date filter, a more accessible flat view toggle, and additional validation rules, including new checks of heat rate, startup/shut down, and outage data.

4

Many New Validation Rules – PowerSimm™ Editor version 4.1 adds many new input data validation checks to help prevent configuration errors in new or updated data. New and updated validation rules for the Generation Editor, Instrument Editor, Forward Curve Editor, and many more, improve the reliability of configurations and data. This includes more checks on generator configuration, trade details, load and pricing data, to name a few. Also, the new Report Manager has improved capability of preventing data- and configuration-related run failures. Building on the input data error checking process in version 4.0, the “Check Data” link allows users to check if their changes (additions or updates) have any issues before submitting the changes to the database.

5

User Interface Integration for Credit Manager – PowerSimm™ now features a user interface for Credit Manager, a credit risk analysis tool for collateral, exposure, and simulated potential future exposure across multiple departments.

Upgrading to PowerSimm™ 4.1 – This new version of PowerSimm™ will be available for installation on ATLAS. For all features to work, a database update is required. Please meet with your Ascend project manager for creating an update plan to review the new editor and develop a deployment testing schedule.
