(CNN) Nearly a year after Hurricane Maria wreaked havoc on Puerto Rico, officials there say power has been restored to most of the island's residents.

Of the nearly 1.4 million customers who lost electric service after the storm, just 25 remain in the dark, the island's electric provider tweeted Monday

The declaration, coming about two months into the start of the Atlantic hurricane season, is a significant development from Puerto Rico Electric Power Authority. The beleaguered state-owned utility has struggled over the last year to recover from last September's storm, which decimated the island's electrical grid. Thousands of people were still without power in June

CNN has reached out to PREPA and has not received a response.
