What is RWE's planned move regarding its stake in Amprion, and how is the grid operator valued?

RWE AG is nearing a deal to boost its stake in Amprion by acquiring Swiss Life’s ~17% stake in M31 — a holding company that owns 74.9% of Amprion — and simultaneously acquiring a 24% stake in M31 from AEBG, an investment group representing five major German medical pension funds; this transaction could value Amprion at about €10 billion ($11.5 billion).

Why is strengthening Germany's transmission grid — particularly Amprion's role — critically important right now?

Germany’s grid needs billions in investment because its buildout has not kept pace with the rapid expansion of renewable-energy output, causing bottlenecks — especially since most wind farms are in the north while demand is concentrated in industrial southern regions — which drives up costs for consumers; Amprion transports electricity to about 29 million people and industrial consumers across seven federal states, mainly in western Germany.
