Unified Energy Systems (UES) is set to restructure its management system in order to prevent any repeats of May’s blackout that saw millions in the Moscow region left without power.

According to UES chairman Alexander Voloshin, in order “to prevent such situations in the future, the strategic and tactical management of the company are being overhauled, and, above all, safety and reliability requirements will be toughened.”

The move is reflected in Moscow distribution company Mosenergo, which plans to invest $500 million in its aging infrastructure, according to its newly appointed head Anatoly Kopsov.

Mosenergo is said to be in talks with Gazprombank and the European Bank for Reconstruction and Development for each to provide up to $250 million in loans.

Kopsov replaced general director Arkady Yevstafyev, who resigned following the blackout.
