The company is not able to handle huge projects on its own as it struggles to reduce its debt.
Reuters reported E.ON board management member Mike Winkel as saying that although the green energy is now growing as a profits source, the company still requires the help of investors for large wind power projects.
The massive surge in renewable energy generation in Europe has negatively impacted E.ON’s conventional coal and gas power plants.
The company has cut down its investments in order to manage its debt of $39.2bn.
E.ON board management member Mike Winkel was quoted by the publication as saying: "We have a big pipeline of developed onshore (wind) projects. But E.ON can no longer meet the capital needs for these projects on its own.
"Therefore, financial investors are very welcome to join and it turns out they see this market as being quite attractive."
The company, since 2007, had invested about €10bn in renewable projects and has about 10,900MW of renewable capacity worldwide, including hydro power, which represents about 17% of its total generation portfolio.
In addition to further expanding its renewable presence in Europe and the US, E.ON is working on onshore wind parks in Turkey.
