Janisse Quiñones, chief executive of the Los Angeles Department of Water and Power, will step down from her position effective March 27, the mayor's office announced.

Quiñones oversees operations of the city's electric grid and water supply systems through the nation's largest municipal utility. Her departure comes weeks after a court found the utility company liable in connection with a fire incident.

Mayor Karen Bass described Quiñones' departure as part of a "planned transition," though the timing has drawn attention given the recent legal ruling against LADWP. The utility serves approximately 4 million residents in Los Angeles and surrounding areas.

No immediate successor has been named for the position. LADWP has faced various operational and legal challenges in recent years, including infrastructure maintenance issues and wildfire-related liability concerns.

The departure represents a significant leadership change for the municipal utility as it continues to address ongoing operational and legal matters affecting service delivery to the region.
