Mainova AG is a multi-utility company based in Frankfurt am Main, Germany, providing electricity, natural gas, water and heat to the city and the Rhine-Main region.[1] The company was formed in 1998 through the merger of Stadtwerke Frankfurt am Main GmbH and Maingas AG.[2] Its current visual identity dates to 2010, when the logo was introduced.[3]
Design and History
The Mainova logo consists of two elements: a pictorial mark called the “Energiewirbel” (energy swirl) and the wordmark “mainova” in lowercase letters.[4] According to the company’s corporate design manual, the logo is normally rendered in blue and red on light backgrounds, or in white and red on dark backgrounds.[4]
The company’s corporate design guidelines, which include the logo specifications, are published on the Mainova website and are updated periodically; the most recent version of the Corporate Design Manual dates from April 2025.[5]
Meaning and Symbolism
The pictorial mark is officially named “Energiewirbel,” which translates to “energy swirl.”[4] The name directly references the company’s energy sector activity, though the company’s design manual does not provide further documented symbolism for the mark beyond this designation.
Typography and Design
The wordmark “mainova” is set in lowercase letters and appears alongside the Energiewirbel symbol.[4] The corporate design manual specifies that the logo is typically displayed in blue and red on light backgrounds, with white and red used on dark backgrounds.[4] The manual does not publicly identify the specific typeface used for the wordmark.
