Tesla discontinues 10 kWh Powerwall; Solar power plant using salt to produce electricity


POV: Power Breakfast

A nearly daily update of energy-related news:

  • Tesla has discontinued manufacturing the 10 kWh residential Powerwall home battery and has removed all references to it from its website. The battery was marketed as a backup power supply in the event that the grid should fail (like during Superstorm Sandy); however, the economics of this battery did not yield desired results. Instead, the company will focus on its 7 kWh Daily Powerwall.
  • A Californian company has created the first-of-its-kind solar power plant that stores electricity using salt. The power plant uses rings of billboard-sized mirrors to reflect the sun onto a salt filled tower. The molten salt boils the water which produces steam that powers electricity-generating turbines. The power plant is a 110 MW facility with 10 hours of energy storage (1,100 MWh of storage), enough to power 75,000 homes.
