Engerati’s Week in Smart Energy: home storage comes of age

Tesla powerwall impact on energy storage sector
Tesla’s Powerwall lithium-ion battery is available in 7kWh and 10kWh

Tesla CEO Elon Musk’s widely anticipated battery storage announcement last week provided much interest, including a new business Tesla Energy and its home and business/grid battery lines Powerwall and Powerpack, writes Jonathan Spencer Jones, contributing editor to Engerati, the sister portal to Metering.com.

Little detail is available yet on Powerpack, and unsurprisingly it is Powerwall, with its massive sales potential, that is attracting the lion’s share of interest.

The lithium-ion battery will be available in two sizes, 7kWh and 10kWh, with the former recommended for daily cycle applications and the latter for backup.

With an Apple-style eye on aesthetics, these are “beautifully functional”, according to Tesla’s website. And their prices, respectively US$3,000 and US$3,500, are equally striking, even with installation costs and profits and the inverter that must be added.

Very much in the spirit of its namesake, the physicist and engineer Nikola Tesla, Tesla touts itself as “not just an automotive company, it’s an energy innovation company”.

It counts an impressive number of partners at the distribution, business and utility levels.

One of the most important of these, SolarCity, has already announced its intention to incorporate the new batteries into its offerings, including its new microgrid-as-a-service, opening up potential globally. [Engerati-Microgrids Now Available As A Service]

Tesla has made no secret of its vision of a battery in every home and its Gigafactory under development in Nevada will give it the power to potentially play a major role in achieving this.

With this latest announcement, Tesla has given the storage market a significant boost and other storage companies will need to step up if they wish to be major players.
