Pila Energy has launched a plug-in home battery storage pilot in New York City, aimed at expanding backup power and helping residents manage energy use, according to Solar Builder.

The pilot, announced during New York Climate Week, includes a program with Brooklyn SolarWorks that will pair rooftop solar with plug-in battery storage, an option Solar Builder reports has been out of reach for most residents of the city until now.

Solar Builder reports that the batteries work with or without solar attached, charging when electricity is cheaper and discharging during peak hours.

The world body has thrown its weight behind a push to accelerate investment in electricity infrastructure across Africa and Southeast Asia, targeting one of the biggest bottlenecks slowing the shift to clean energy, according to Climate Home News.

The Global Grids Accelerator is designed to convert government plans for expanding and modernising power networks into investment-ready projects, and to marshal the expertise, financing and support required to build them, Climate Home News reported.

The initiative will not set up a new financing institution, and no additional funding for grid upgrades was announced alongside the launch, per Climate Home News. Instead, it will function as a broker, drawing together international agencies, development banks, investors and utilities around grid priorities identified by governments.
