Tesla’s new battery system could build a more resilient grid

Tesla has launched a new battery product that aims to increase the feasibility of renewable energy and create a more dynamic future energy grid.

The Powerwall is a wall-mounted, modular battery that enables customers to store energy captured via solar panels or during period of low energy prices. In the past, the inability to store energy in this way – especially in areas with intermittent sunshine – had been a barrier to more widespread adoption of solar power. According to Tesla, which describes itself as an ‘energy innovation company’, the use of battery systems like the Powerwall could mean a “cleaner, smaller, and more resilient energy grid”.

Tesla also see a range of other benefits for this system, including:

  • Load shifting – The battery can provide financial savings to its owner by charging during low rate periods when demand for electricity is lower and discharging during more expensive rate periods when electricity demand is higher
  • Increasing self-consumption of solar power generation – The battery can store surplus solar energy not used at the time it is generated and use that energy later when the sun is not shining
  • Back-up power – Assures power in the event of an outage

As well as residential uses, the company has also developed similar solutions for business and utility applications.

This is a timely announcement from Tesla, following the release of a recent report from the Rocky Mountain Institute which predicted that grid-connected, solar-plus-battery systems may soon be viable, enabling customers to begin to reduce their reliance on the electricity grid.
