Tesla doubles the power output of the Powerwall without changing the price

375OJ1bTesla Motors held its 2015 Annual Shareholders Meeting today at the Computer History Museum in Mountain View. During his presentation, Elon Musk, Tesla’s CEO, announced that Tesla will be doubling the power output of the Powerwall, Tesla’s residential energy storage system, to 7KW at peak usage and 5KW for steady usage.

Musk confirmed that the price will remain the same, $3,000 for the 7KWh daily cycle version and $3,500 for the 10KWh weekly cycle version.

Tesla offers 2 different versions of the Powerwall battery system. The 7KWh pack is built to be discharged daily in order to take advantage of a solar power installation or to manage usage, especially if you are paying your electric utility by time-of-use. It could also be combined with multiple packs in order to take a solar installation completely off-grid. The 10KWh pack is meant to be use as a backup power system. Ideally, it should only be use in case of power outages, but the battery pack is built to withstand weekly cycles for over 10 years.

Musk admitted that even though the demand for the Powerwall has been overwhelming with over 38,000 reservations in just one week, the overall reaction was mixed. The biggest complaint was the steady output of only 2KW which isn’t really enough for an average household. They listened to the complaints and adjusted the offering to a now impressive 5KW.

Tesla’s CEO reiterated that the company expects demand for energy storage to mainly come from utilities. He said that as much as 80% of Tesla’s stationary storage capacity should go to utility scale project. Last week, Tesla closed on a 500MWh deal with Advanced Microgrid Solutions to supply the company with battery packs for electric utilities. Musk described Tesla’s solution as a “plug and play” option for utilities which can be installed in existing electric substations.

During the meeting, JB Straubel, Tesla’s Chief Technology Officer, said he expects that wide adoption of energy storage at the utility level will help the electric companies to take full advantage of their infrastructure investments by leveling the electric load.

Even with these changes in power output, the Powerwall is still expected to start deliveries later this summer and then to ramp up next year as Tesla shifts production of the battery packs to their “Gigafactory” in Nevada.

  1. […] In the modern era, most people have become used to getting less bang for their buck over time. However, Tesla CEO Elon Musk is evidently out to change this — at least in terms of his company’s products. During Tesla’s 2015 Annual Shareholders Meeting on June 9, Musk said that the Powerwall will double in power output while staying at the same price, according to Electrek. […]

    Habrá que ver la forma de hacerse contrabandista de baterías en España. No se puede tolerar que un gobierno fascista ponga impuestos al sol para frenar la industrialización y el desarrollo tecnológico. Eso ya lo hizo Franco ebn la dictadura militar y ahora quiere hacerlo el Gobierno del PP. Desobediencia civil ¡ya!.
    Nota: en España te persigue el Gobierno por decir lo que estoy diciendo.

    Dear sirs
    What is the final cost of each KW ?
    best regards.

      I’m pretty sure you meant KWh and not KW.

      It would be something impossible to calculate without knowing to true lifetime of the product, but if we use Tesla’s warranty of 10 years, we could come up with this simple calculation:

      10 years * 365 days = 3,650 daily cycling

      3,650 daily cycling x 7 KWh = 25,550 total KWh

      $3,000 / 25,550 KWh = $0.12/KWh

      so based on the warranty you would had a cost of $0.12 per KWh that goes through the Powerwall.

      Of course this is without the cost of an inverter nor the generation cost, but also, I would expect these packs to last for much more than 3,650 cycling.

    I watched that meeting where Musk confirmed the PowerWall output would be more than doubled but even today, the old numbers are still listed on the Tesla Energy page
