The international credit rating agency S&P Global Ratings has raised Latvian transmission system operator's Augstsprieguma tīkls AS (AST) long-term credit rating from BBB+ to A- with a stable outlook.

The upgrading was a result of AST's successful EUR 116.2 million loan refinancing by issuing EUR 100 million in Green bonds on 13 October.
