Innogy, the green subsidiary of German energy provider RWE, could be the biggest stock market launch of any German company since the year 2000 – but renewable energy likely only plays a minor role for its expected success, write Varinia Bernau and Angelika Slavik in the Süddeutsche Zeitung. Innogy's cooperation with a number of innovative green energy start-ups has won it the plaudits of critics such as Greenpeace. Yet, only about 15 percent of its profits are generated with renewables. The bulk of its market value stems from the grids that Innogy operates, Bernau and Slavik argue. While profits in this sector are capped by the Federal Network Agency, they are also secure for years to come. See the article in German here.
