The FBI pilot
The report on improved battery and booster installation in weak grids was written by Thomas Veflingstad of Elvia and Per Olav Dypvik of Energea, later head of eqGrid.
Smartgrids IDE Forbedret batteri og boosterinstallasjonFrom R&D and pilots to eqGrid
Practical grid development, pilot projects and technology work lie behind eqGrid.
energiScada and eqGrid build on several years of work with Elvia in the IDE programme, including the OLTC pilot for voltage regulation and the FBI pilot for battery support in weak grids.
The work provided experience with voltage quality, available capacity, smart-meter (AMS) data, battery support and operation in distribution grids with limited capacity.
From IDE pilots to product
The lessons from the OLTC and FBI pilots, combined with the development of a patented no-break voltage selector, form the basis for eqGrid.
The goal is to ensure voltage quality within EN50160/FoL and increase available capacity in the existing grid.
eFlow: ongoing trial with Elvia
eqGrid is currently being trialled with Elvia in the eFlow project, supported by Enova through the «Flexibility in the energy system» programme.

The work behind eqGrid builds on practical pilot projects and reporting from the Norwegian Smart Grid Centre's IDE programme.
The OLTC pilot
The OLTC pilot for automatic voltage regulation was led by Kjell Anders Tutvedt of Elvia, who is also project manager for the eFlow project.

The work from the OLTC pilot was later presented internationally at
the CIRED Workshop 2024 in Vienna.

Three development tracks that meet in eqGrid
eqGrid is the result of several parallel development efforts within regulation, battery support and voltage control.
energiScada
A regulation and control system developed from fouScada, miniDrops, smart-meter (AMS) data and practical OLTC operation.
Battery and grid support
Experience from BFS technology and the FBI pilot, focused on voltage stabilisation and weak distribution grids.
Patented voltage selector
Proprietary technology for no-break voltage regulation with a standard transformer architecture.
What eqGrid solves
- Voltage quality within EN50160/FoL
- Reduced voltage variations
- Better phase balance
- Increased available capacity
- Deferred need for grid reinforcement
Topology-independent architecture
eqGrid establishes an internal TN environment for battery and regulation, but can be adapted to IT, TT and TN grids.
- Standardised internal regulation
- Simpler battery integration
- Greater flexibility during installation
