Generator Installation in Washington, DC
The June 2012 derecho left most of the Washington region without power, some homes for a week in extreme heat, and summer storms and winter ice still cause outages. In rowhouse neighborhoods such as Capitol Hill and Petworth, yards are small and generators must run outdoors away from windows, so a portable generator with an outdoor inlet and interlock in a rear yard is the usual choice.

What's different about generator installation in Washington
Detached homes in Chevy Chase DC and Takoma may suit a standby generator. Pepco owns the service, and permits come from the Department of Buildings.
Basement apartments, kitchen remodels, heat pumps and EV chargers are common reasons to upgrade a service. Many homes are in historic districts, which can affect exterior work such as meters, service masts and outdoor equipment.
Weather and the utility in Washington
Washington summers are hot and humid, and thunderstorms bring outages and surges, especially in neighborhoods with large trees over overhead lines. The June 2012 derecho caused widespread outages across the region. Winters bring occasional heavy snow and ice. Rowhome basements can take on water in heavy rain, which matters because that is often where the panel and meter are. Pepco serves the District and handles meters, service drops and reconnection after upgrades. DC has run programs supporting electrification and efficiency, and incentives change over time, so check what is currently offered.
