List of the 75 largest renewable energy investors in Germany [2025]

Description

List of 3 large renewable energy investors in Germany

Germany’s sustainable energy sector has grown in recent years – the country’s goal is to generate 40-45% of its electricity from renewable sources by 2025. Currently, the share of renewable energy in German electricity generation is around 35%. Wind power is by far the most widely used form of energy in Germany. This environment is generating a lot of interest in the German investment sector. German energy investors are mostly active across Europe and are interested in solar investments in warmer countries such as Portugal or Spain, as well as investments in Nordic countries with high wind and hydro potential. The following article profiles three German investors active in the renewable energy sector.

1. Aquila Capital (Hamburg)

Headquartered in Hamburg, Germany, Aquila Capital is one of Germany’s leading renewable energy investors, with approximately €11 billion under management. The investor has a diversified portfolio and invests not only in standard solar and wind energy but also in hydropower and green logistics. Founded in 2001, Aquila has a total of around 10GW of renewable energy in its portfolio.

Update: In January 2024, Commerzbank obtained a 74.9% controlling interest in the German asset manager Aquila Capital. Aquila Group will retain the remaining 25.1% stake, and the completion of the deal is anticipated in the second quarter of this year.

2. CEE Group (Hamburg)

Also based in Hamburg, CEE Group is slightly older than Aquila, having been founded in 2000. Over the past 20 years, the investor has invested more than €1.9 billion in wind and solar assets in Central Europe. These two asset classes, solar and wind, are the investor’s core expertise. The geographical focus of CEE Europe is on Germany, France, Sweden, and the Netherlands. This focus also makes the German renewable energy investor one of the largest investors and providers of wind and solar energy in Europe.

Update: CEE Group has acquired an 80.9-MWp solar project near Berlin from Chint Solar. Construction started in February 2024. It’s the first transaction through CEE Renewable Fund 8. The fund, launched in 2023, will own 55% of the solar park, and CEE Group will hold the remaining 45%. Overall, CEE Group’s portfolio currently includes 49 solar projects (1,006 MWp) and 46 onshore wind farms (655 MW) in Europe.

3. EWE Erneuerbare Energien (Oldenburg)

Sydney-based Macquarie Group Limited has acquired Green Investment Group after five years in the green infrastructure space. As a result, the Edinburgh-based developer represents one of the world’s largest dedicated green infrastructure investor and developer teams, with the overall aim of accelerating the energy transition. While GIG manages renewable energy projects worldwide, its portfolio of developed projects includes offshore wind farms, solar farms and onshore wind farms. The offshore wind farms alone produce approximately 8GW of wind energy.
