TenneT says working with EU on cross-border grid issues

BRUSSELS, March 19 (Reuters) - German grid company TenneT is working with the European Commission to find solutions to cross-border grid issues for which it is under antitrust investigation by Brussels, it said on Monday.

EU antitrust authorities on Monday launched an investigation into whether limits placed by TenneT -- a subsidiary of TenneT Holding <IPO-TTH.AS>, the Dutch government-owned operator of electrical grids in the Netherlands and Germany -- on cross-border electricity capacity with Denmark breaches EU antitrust rules.

TenneT said the German-Danish border suffered from transmission bottlenecks, adding that transmission capacities were stretched to the limit because of market liberalization and the transition to renewable energy.

A statement from TenneT said the EU investigation will include calculations on whether capacities approved under European law put foreign providers at an unfair disadvantage.

"The examination can therefore set a precedent for all border connections in Europe," it added. (Reporting by Alissa de Carbonnel Editing by David Goodman)
