The energy transition is transforming the operational environment for distribution system operators (DSOs). Wind farms, solar parks, battery storage systems and electric boilers are rapidly increasing the number and complexity of grid connection requests. At the same time, regulations are tightening, and the need for technical expertise is growing.
For small and mid-sized DSOs, this change poses real challenges: legacy software, limited resources and unfamiliarity with processes such as Grid code specifications for powerplants and grid code specifications for grid energy storage systems make it difficult to ensure compliance and network reliability. When in-house capacity isn’t enough, a trusted partner is essential.

In a reactor switching surge analysis, Ampner simulated two reactors with different power levels on a 110 kV network, verifying equipment safety and compliance with power quality standards.
Looking Ahead: Modeling Is at the Core of the Future Grid
Bidirectional power flows, large-scale battery systems, growing data centers and hydrogen projects all demand more precise grid models and protection logic. Meanwhile, Fingrid’s updated response-time requirements and regulatory obligations are pushing DSOs to ensure their modeling and documentation remain up to date.
Ampner aims to meet the growing demand by continuously developing its modeling services and strengthening its expertise in supporting distribution network operators. Every successful project strengthens the energy ecosystem as a whole.
Ampner – Confidence Through Expertise
By combining deep technical knowledge with a flexible partnership approach, Ampner helps DSOs navigate the complexity of the modern power grid — delivering confidence, reliability and long-term value.
