How did the Russia-Ukraine gas dispute affect Bulgaria in January 2009?

In January 2009, a dispute over natural gas deliveries between Russia and Ukraine resulted in a significant disruption of supply throughout eastern and southern Europe. This crisis severely impacted Bulgaria during an extremely cold month, leaving thousands of Bulgarians without electricity or heat. Additionally, the disruption forced major enterprises across the country to halt production.1

The crisis highlighted the vulnerabilities of the government led by Sergei Stanishev, which was already facing challenges related to the global recession and allegations of corruption.1
