Is Tesla’s Powerwall battery a utility killer?

Problem:  There is a often a mismatch between when solar is generated and when it is consumed resulting in continued reliance on power plants to supply our electricity and higher carbon emissions. The storage challenge is a key factor in preventing the transition to a low-carbon economy.

Main ideas:

1. Elon Musk, of Solar City and Tesla Motors fame, is gunning to shift the global energy systems toward greater use of renewable power. His solution is a new modular rechargeable lithium-ion battery units called the Powerwall system.

2. Being able to inexpensively store power from renewable sources for use when needed relieves the grid during peak consumption (load shifting) and supports decentralization of energy production.

3.  The Powerwall is positioned to make competitively-priced battery storage available at the retail level to homeowners and small businesses as well as industrial options to utilities.  This could tip the market in favor of renewables.

Organizational Stakeholders who will use the product:

1. Retail consumers (homeowners)

2. Small businesses

3.  Industrial/utility

Steps to deploying:

1.  Complete any testing/pre-market trials  and begin production in keeping with sales forecast

2. Select and train third party installers for deep market penetration

3. Launch product into market through education and social media campaigns targeted to segmented consumers

  1. The use of batteries for load shifting in conjunction with renewable power will allow for a reduction of fossil fuel usage, resulting in reduced carbon emissions.


  2. Very cool. I’ll be curious to see if any utility companies choose to partner with Tesla on this technology.


  3. Customers in California who are subject to time-of-use rates indicates that attractive rates of return of 20-30% may be possible when existing state and federal incentives are incorporated. Without such incentives, however, it’s difficult to see how a strong business case can be constructed for residential energy storage systems at the present time; in fact, most system installers to date have focused entirely on the value of residential storage as a backup system would should leave utilities unharmed at the present moment.


  4. This could be extremely valuable in alleviating our stressed energy grid infrastructure. Having decentralized power production which is then stored locally can save costs of grid maintenance especially to remote areas.
