How it works

Existing grid connections
as a new source of value

The business model of ReGrid Capital GmbH is based on a simple, yet highly effective idea:

We utilize existing, unused grid connections to operate battery storage systems economically.

Instead of elaborately planning new infrastructures, we implement Battery Energy Storage System (BESS) projects at locations that already possess powerful grid connections – such as decommissioned industrial or commercial sites.

This saves time, costs, and approval efforts while simultaneously unlocking attractive returns from the energy market.

How our model works
In four steps to a source of revenue

Our battery storage systems charge energy from the grid when prices are low or even negative, and feed it back in when electricity prices rise.

This principle is called electricity price arbitrage – and enables predictable, high-yield revenues from price volatilities in the energy market.

Site Analysis

We assess the technical suitability, connection capacity, and regulatory framework of your site.

Project & Approval

ReGrid Capital handles planning, grid compatibility assessment, and coordination with the relevant grid operators.

Installation & Operation

We install and operate the battery storage system, including the EMS (Energy Management System) – fully automated.

Energy Trading & Revenue

Our system uses real-time electricity market data to optimize charging and discharging operations — for maximum profitability.

The principle: Grid connection → BESS → Electricity market → Revenue

An existing grid connection becomes a platform for:

Storing energy at low prices,
Supplying energy at high market prices,
and continuous returns through automated price optimization.

This creates a new form of value creation from existing infrastructure – efficient, low-risk, and sustainable.

Why Existing Grid Connections?

Faster

No lengthy approvals or grid compatibility assessments as with new constructions.

More Economical

Investment costs are significantly lower – existing grid capacity is simply utilized.

More Sustainable

Existing areas are reactivated instead of sealing new ones.

Legally Secure

Separation from the existing building network – operation via its own meter with an independent market role (MaLo).
