Our customers

Managed grid models in numbers

Today, more than 55 customers in Germany and Europe have already decided to use our system. Thanks to the modular platform approach, our solution can be scaled as required. Today, millions of data points are already managed in the Intelligent Grid Platform, adding up to a significant part of the total German medium and low-voltage grid.

Data Grid Quality Checklist

Infopaper: Shit In = Shit Out?

Grid Data Quality – The Ultimate Checklist

High data quality is a default precondition for digitalizing and automating many processes that are currently seen as a bottleneck for a fast energy transition. Yet many DSOs we speak to wish their data had much higher quality than it is now. At the heart of this issue lies the problem of “Shit in = Shit out”. When data has been input incorrectly, it affects analytics, insights, planning and investment decisions. In this infopaper, you’ll find how to tackle this problem step by step.

Case study: Helen Electricity Network

Running future grid scenarios to determine the probability of bottlenecks

Helsinki aims to become emission-free by 2030, necessitating a major transformation of its energy systems. This presents challenges for the power grid, requiring a thorough understanding of the impacts of these changes. Using the IGP app Grid Study, Helen Electricity Network is modeling three potential future grid scenarios. These scenarios, reflecting current and projected socio-economic developments, will help determine grid needs over the next 5, 10, and 15 years.

envelio Case Study Syna

Case study: Syna

Automation and acceleration of grid compatibility testing

With the introduction of the Intelligent Grid Platform (IGP), Syna has drastically reduced the time required for grid connection evaluation for larger installations: The grid compatibility testing, which previously took up to 8 hours, can now be completed in about 15 minutes. At the same time, the significant improvement in the quality of the grid calculations helps ensure supply reliability, as the impact of new connections on the grid can be assessed more reliably.

Case study: Elektrilevi

Accelerated processing of connection requests

To cope with an extremely high number of connection requests, Elektrilevi introduced a self-service portal for its customers to perform a pre-application research on the nearest favourable connection point and get an estimation for the project’s duration and costs. At the same time, this Estonian grid operator fully automated processing of connection requests for microproducers of up to 15 kW.

Case Study: FairNetz Part 2

Improved data quality through higher grid transparency

This case study builds upon the first part and invites us to follow up on the progress of the implementation of the Intelligent Grid Platform at FairNetz. The electricity network operator from Reutlingen now leverages the improved data quality to speed up the processing of grid connection requests. For instance, 50% of all requests for new connections are assessed positively in under 5 minutes. Additionally, FairNetz relies on the IGP as its “Single Source of Truth” for analyzing the grid participant structure, aiming to further improve the data basis for the calculation logic and create a foundation for sound grid expansion investments.

Case Study: FairNetz Part 1

Development and validation of exhaustive digital grid models

With the help of the Intelligent Grid Platform, FairNetz was able to automatically detect inconsistencies and information gaps in its data source systems. This enabled the German grid operator to significantly improve the quality of grid data and create a dynamic grid model for their entire MV- and LV network. Moreover, FairNetz achieved a higher transparency of network load and was able to identify critical assets and problem grid areas.

Case study: E.DIS Netz GmbH

Digital and automated connection process

The major German DSO E.DIS Netz GmbH accelerates the previously manual evaluation process for new connections by a complete process integration of the Intelligent Grid Platform. In addition, E.DIS has implemented an online portal based on the Intelligent Grid Platform. Without input from a grid planner, potential customers can obtain an initial assessment of the best possible grid connection point for their planned assets.

Whitepaper: DER Connection process

Relevance in European distribution grids

In this white paper, we focus on the specific challenges and potential solutions associated with the DER connection process in Europe as a key example of the innovation needs in European distribution grids. After a brief introduction on the current steps, challenges and framework conditions for the DER connection request process, we provide a brief overview of the topic’s relevance for the next years and conclude with a few innovative ways that can help capitalize on digitalization and automation.

White paper: Interconnection Process

Evolution of the DER interconnection process in North America

In this white paper, we identify gaps and, more importantly, opportunities for improvement in the current approach undertaken by grid operators of all sizes. And it outlines how these entities are able to utilize innovative software solutions from our partners in conjunction with our own Intelligent Grid Platform. Our ultimate goal with this paper is to share our learnings from discussions with many DSO’s so that all groups affected by this evolution including regulators, utilities, DER providers, and other industry stakeholders, are able to recognize and facilitate the change needed to transition to a cleaner, more affordable and resilient grid.

Digital Twin Webinar On-Demand

Webinar On-Demand: Grid Digital Twins

Enabling better transparency and improving grid reliability

In this webinar, we’ll draw from our experience of working with European distribution grid operators (DSOs) on digital twins of their grids and take a look at the various aspects of creating a digital twin of a power grid. We’ll talk about the data quality and how high it must be to start building a functional grid digital twin, give you an overview of how a digital twin helps ensure grid stability by providing real-time insights into the grid ecosystem, and review the best practices for leveraging the digital twin technology to optimize resource management and reduce costs.
Exclusively for DSOs and Utilities!
