Bullfrog Energy is an operational investor in energy storage that makes renewables dispatchable. Anchored in Germany, active across Europe.

Bullfrog is an independent flexibility platform and operational investor.

The Problem

Grids are at their limit.

New power generation is outpacing grid expansion, and congestion is now a structural constraint.

€3.1bn

Grid balancing costs

9.4 TWh

Renewable power curtailed

Curtailed power increase 2024 vs 2025

€10bn

Grid upgrade costs demand by 2030

All figures refer to Germany (2025).

The Challenge

Hard to access. Harder to execute.

Institutional capital requires portfolios, not single assets. But the market is fragmented into individual projects, each with its own permits and grid connection agreements. Building a portfolio takes local presence as well as legal and regulatory know-how.

The mission

Securing the future of power supply.

Energy storage turns renewable energy into reliable power.

Storage provides flexibility where it is needed. It turns curtailed renewable output into dispatchable, reliable power. We aim to lower energy costs and increase the value of renewable power, while delivering solid returns for our investors.

The Solution

An operational investor, focused on execution.

01 Acquire

We buy and hold. Fully financed, we acquire projects at RTB, manage them to COD. Each asset adds scale and diversification to our portfolio.

02 Deliver

As an operational investor we manage every step from signing to operation. We run the transaction, oversee EPC and O&M partners, and structure the right offtake for each asset.

03 Manage

We aggregate our assets into one fleet and trade it across day-ahead, intraday and ancillary services markets. Digital monitoring tracks asset health and investors receive regular reporting.

We diligently manage what we buy.

Most project developers exit at commissioning. Bullfrog builds a long-term portfolio, taking responsibility for risk management, execution and asset management across each asset's life.
