The medium-voltage grid requires customization: manual calculations per customer are time-consuming and not scalable. Enexis wants proactive insight into grid capacity and future investments.<\/p>

This requires network architects and IT to work closely together to develop and adopt a new, more efficient way of working. This involves network architects and IT working closely together to create and adopt a new, more efficient approach.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Following an earlier collaboration on low-voltage networks, Enexis approached nlmtd again. This time with a follow-up question: How can we make the energy transition at the medium-voltage level concrete and transparent?<\/p>

For the low-voltage grid, in cooperation with Enexis, we had already developed tooling to gain insight into the grid proactively. This tooling enabled the identification of time bottlenecks and the development of appropriate solutions. Based on this work package, the large-scale neighborhood approach could be started. There was a similar demand for the medium-voltage grid, but the work was fundamentally different. Fewer standard calculations were possible, which required more customization.<\/p>

Together, we developed the program Meters Maken op Middenspanning <\/em>(Making Progress on Medium Voltage),<\/em> a new method, vision, and set of tools. The result? Faster insight, standardized policy, and a solid foundation for a future-proof electricity grid.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The load on the medium-voltage network was previously calculated manually, with high precision, by network architects for each customer demand. This required a significant workforce, time, and money. Given the pace of the energy transition and the enormous increase in power demand, such a reactive approach was no longer tenable. The need arose to monitor developments in the local electricity grid proactively and to make large-scale, future-proof investments in the medium-voltage networks. So that grid expansions and acquisitions could be initiated more effectively and efficiently. <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

On the one hand, this requires a new way of working: architects must be able to trust the forecasts and tooling and cooperate intensively with IT. On the other hand, the project acts as a catalyst for change within the department. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

In collaboration with Manager Net & Capacity Management MS\/LS Thijs Derksen and his core team, a clear mission and vision for the department was established. A roadmap was then used to clarify what was needed to realize that mission. Making it concrete made it clear how extensive the project would be and that a new approach was required.<\/p>

Enexis’ mission is to obtain up-to-date insights into the medium-voltage grid, assess the impact of developments, and develop proactive, multi-year work packages. To achieve this, enmtd set up the Making Progress on Medium Voltage<\/em>\u00a0program. Significant attention was also paid to change management. Teams have been tasked with defining their own grid vision, ensuring ownership, commitment, and accountability.<\/p>

In consultation with the teams involved, a new 10-year vision for medium-voltage was developed: strong in terms of content, visually appealing, and elaborated for each grid area. This network vision provides direction and foundation for future investment decisions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

New tooling <\/strong>
In collaboration with Enexis ICT’s development teams, we began designing new tooling. By having network architects work directly with ICT, both domain knowledge and mutual trust grew. The tooling was developed by Enexis ICT, in collaboration with regular suppliers. An automated flow replaced manual calculations. This increased awareness of grid capacity and bottlenecks led to faster, better-informed decisions.<\/p>

Proactive role for network architects
<\/strong>For network architects, the new tooling means a significant change. Manual calculations disappear, raising questions such as: What should we focus on? What work is falling away? What do we need to keep up with this new way of working? <\/em>
Together with Enexis, we opened communication channels with other departments, organized webinars on the grid vision, and set up an internal roadshow. In this way, the energy transition was widely supported within the organization. This helped architects adopt a proactive role towards their colleagues.<\/p>

Data-driven work
<\/strong>Based on data-driven future projections, investments are now being made in robust solutions. No longer reactive, but proactive. This saves time, prevents fragmentation, and improves decision-making for network architects and the rest of the organization.<\/p>

Standardized policies
<\/strong>Combining innovative tooling with streamlined policies has also improved the way we work. Where previously different approaches existed, and no standard cable was used, the same cable is now proposed in 90% of cases. This accelerates decision-making, simplifies calculations, and makes procurement more efficient.
In short: data-driven work with a high degree of automation and standardization.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
