Projects
We have ongoing projects that we would like to share with you
Pilot at Lierne
Our battery installation in Lierne is the first of its kind. Here we examine the effect of batteries on voltage regulation in the network together with the network operator Tensio.
The aim of the pilot is to help raise the voltage in a weak network, to enable more industrial customers in the area to increase their electricity consumption without Tensio having to do other network boosters.
Our preliminary results show:
✔️ Good voltage support and range
✔️ Avoids expensive network expansion
✔️ Reduced transmission loss by 22%
✔️ Successful participation in the FFR market
Peak Shaper teamed up with the local DSO, Tensio, to test the battery installation placed in the 22 kV radial network at Lierne. Lierne is an area with increasing load and challenged supply quality and is therefore an area where a battery installation can prove to be a beneficial grid strengthening measure.
Founders Friday on Corporate Venturing
On Friday 26 January, a new Founders Friday will be held where you will have the opportunity to hear the fascinating story of Peak Shaper, Norway's first commercial battery service for large-scale batteries.
Key findings
This pilot project shows that a battery installation is a powerful tool for network reinforcement and loss reduction in the distribution network. It also shows great potential for improved quality of supply in weak power systems and expansion of the viable technical function of the distribution network.
We see that batteries have a good effect on the voltage, which has been our challenge in the Jule industrial area.
Strengthening the quality of supply through voltage support
The first two tests were carried out to investigate how BESS affects the grid voltage locally at the battery installation, as well as further out in the grid. The test periods observed a significant increase in voltage during discharge of the battery.
Measurements confirmed that the largest increase in voltage observed in the grid was during complex power discharge.
An increase in voltage has also been observed as far as 14 km away from the battery installation. This shows that centrally located batteries can support grid owners in a larger problem area, thereby solving problems for a larger number of energy consumers.

FRR MARKET PARTICIPATION
The batteries used in the pilot case have been eligible for FRR market participation, and have been sold in this market during the summer of 2023. This additional value stream allows for reduced rental costs, to the benefit of the grid operator without compromising the grid support purpose of the battery system.
