A sudden and unexplained reduction in Iranian electricity supply plunged Iraq's eastern province of Diyala into a partial blackout on Saturday, highlighting Iraq's ongoing dependence on Iranian power.
The cut, which slashed about half of the electricity Iran provides to Diyala, severely disrupted power in the province's eastern, northern, and northeastern regions, according to Aws al-Mahdawi, a Diyala Provincial Council member.
"It could be a technical issue or related to re-programming codes," al-Mahdawi told Rudaw, a media outlet in the Iraq’s Kurdistan region.
This latest incident follows a history of disruptions to the Mirsad power line, alongside Iran's own energy shortages which have seen extensive blackouts, most recently forcing working weeks down to two or three days in large swathes of the country.
During Iraqi Prime Minister Mohammed Shia' al-Sudani's visit to Tehran in January, officials announced plans to restore 625 megawatts through the Mirsad, Karkha, and Siril lines.
Iraq depends on Iranian electricity and gas imports to bolster its own power generation. To mitigate the impact of US sanctions on Iranian exports, Washington has repeatedly granted Iraq four-month waivers, allowing continued energy purchases.
These waivers, recently extended in the summer for 120 days and nearing expiration, are intended as a temporary measure until Iraq can achieve energy independence.
In early February, US President Donald Trump issued a directive to reinstate the 'maximum pressure' policy on Tehran. The directive signaled a potential end to sanctions waivers, saying, “The Secretary of State will also modify or rescind existing sanctions waivers.”
