Skive Sports Arena: Enhancing Grid Stability with Xolta’s Smart Storage Solution

Executive Summary
The Skive Sports Arena, equipped with a 75 kW PV plant, faced challenges with voltage fluctuations on sunny days due to the lack of automated voltage support in the local grid. Xolta’s innovative energy storage solution, featuring an energy flux control algorithm, now enables optimal solar energy utilization, stabilizing the grid and reducing energy costs for the arena.

Project Overview

Location: Skive Sports Arena

Challenge: Voltage level fluctuations in the local feeder line due to inconsistent solar energy injection, requiring manual transformer adjustments.

The Situation
The sports arena’s solar plant contributed to voltage instability in Skive’s grid, necessitating manual intervention for voltage balancing. This inefficiency highlighted the need for a solution that could manage solar energy injection more effectively.

The Solution
Xolta implemented an advanced energy storage system at the arena, equipped with a cutting-edge energy flux control algorithm. This system intelligently delays battery charging to coincide with solar peak production times, ensuring that solar energy is injected into the grid only at optimal moments.

The Outcome

  • Grid Stability: The solution has significantly mitigated voltage fluctuations for the grid operator, eliminating the need for manual transformer adjustments and preventing the high costs associated with grid reinforcement.
  • Cost Savings: For the Skive Sports Arena, the ability to store and use solar energy precisely when needed has led to substantial energy cost reductions, particularly beneficial after the end of the current feed-in tariff scheme.


The collaboration between Xolta and Skive Sports Arena showcases the potential of smart energy storage to address grid stability challenges and optimize renewable energy usage. This case study serves as a blueprint for similar facilities looking to enhance their energy efficiency and grid compatibility.
