The energy storage in question—a series of sodium–sulfur batteries from Japan's NGK Insulators, Ltd.—can store roughly seven megawatt-hours of power, meaning the 20 batteries are capable of delivering roughly one megawatt of electricity almost instantaneously, enough to power 500 average American homes for seven hours.
