Berlin and The Hague are reportedly attempting to sell TenneT’s German unit by mid-October, a move aimed at accelerating its energy transformation.

The deal is part of TenneT’s plan to spend 111 billion euros ($119 billion) over the next decade to modernize land and North Sea grid infrastructure, 60% of which is in Germany.

Negotiations have been hampered by disagreements about the German division’s price.

The Dutch finance ministry and TenneT have agreed on several topics, but valuation remains a sticking point.

The German economy ministry has not responded to the reports.
