California-based solar developer SolarReserve announced Thursday that it has completed the 540-foot tower at the center of its Crescent Dunes solar-power plant on federal land near Tonopah.

The tower is key to the plant's operation: Its apex contains the receiver that will field sun rays directed by hundreds of small mirrors. The receiver's heat exchanger will then transfer that sun power into molten salt, which will then be stored in tanks to provide power through the night.
