Version 25.5

Released on 21.10.2025

New Features

Improved Unbalanced Power Flow table for Phase Comparison

Enhanced the Unbalanced Power Flow table UI to allow easy comparison of results across different phases side by side. Users can easily spot variations in voltage, power, and other key metrics, helping to analyze phase imbalances more clearly.

CSV Import with Generator Retention

When importing a customer list containing loads and generators, users can now choose to keep existing generators instead of replacing them. This option is available in the Grid Editor wizard and ensures flexibility for scenarios like grid upgrades or pilot projects using external data sources (e.g., PV potential maps).

ESRI Online Integration

Customers using ESRI as their GIS platform can now log in with their ESRI credentials to access their own map layers. Once authenticated, they can view their ESRI data directly in the platform either as base maps or overlay layers for enhanced visualization.

Dynamic Feeder Loading Limits

Feeder loading limits for transformers inside stations have been updated to allow setting maximum hosting capacity for generation and load on all lines leaving a substation. This approach applies feeder-based limits, removing the need for higher-voltage network data. The result is more accurate hosting capacity estimates and faster calculations.

Expanded Power flow simulation Results

Users can now see current (A) and apparent power (S) alongside active and reactive power in the load tab for both static power flow and time-series simulations. This makes it easier to understand current patterns and overall power behavior in grid analysis.

Multi-Result Hosting Capacity Evaluation

Introduced the ability to evaluate multiple Hosting Capacity results in a single consolidated table for easier comparison.

Improvements

  • N-1 Analysis Enhancements: Added tabs for lines, connections, and transformers on the N-1 page. Violations overview is now included in the N-1 report.
  • Power Flow Warnings: A warning is displayed when running a power flow with disconnected loads or generators.
  • External Powerflow API Upgrade: The API now supports replacing existing loads and generators for better flexibility.
  • Performance Boost for Newton-Raphson: Improved Newton-Raphson power flow performance, which also accelerates hosting capacity calculations.
  • Time Series Download Optimization: Introduced multi-layer parallelism with separate grid and meter concurrency settings to significantly improve time series download speed.
  • Project Overview .Mon Tab Improvements: Enhanced performance and added more warning/violation details. The tab now uses the new search/list functionality for faster loading of thousands of entries (e.g., connection requests).
  • Reactive Power Selection Upgrade: Reimplemented selection logic to allow choosing “Capacitive” or “Inductive” everywhere in the platform. In pages like the grid editor, you can now set reactive power type along with power factor (cos φ).
  • Hosting Capacity Iteration Logic: In the first iteration, the system calculates the contribution factor. If it exceeds a defined threshold and triggers a violation, the process stops immediately and sets the capacity to 0 kW. The contribution factor calculation has also been refined for greater accuracy.
  • Spanish Ruleset Update: Maximum power rules now apply to buses of any voltage level (previously limited to certain ranges).
  • Phase Identification Overview: Added a progress overview for phase identification on the Project Overview page.
  • Minimum Power Limit Handling: Instead of restricting power below the minimum limit, the system now logs it under specific conditions (e.g., bus has a stationID, station type is “SUBSTATION,” and request meets defined criteria).

Bugfixes

Grid

  • Fixed API behavior to allow importing customers with zero-valued power; loads without annual energy now correctly set active power to 0.
  • Fixed an issue where stations appeared empty on the Project Overview page.
  • Fixed a 404 error when clicking the cross-hair icon of a transformer moved during grid reconfiguration; routing and history now update properly.
  • Fixed table visibility when reopening the History panel.
  • Fixed overlapping line ends when they weren’t connected to a bus.
  • Fixed incorrect “A newer version exists” message when editing grid elements after a grid upgrade status change.
  • Fixed polygon shape drawing issues in the grid editor.
