Modern household energy storage industry

Why are residential energy storage systems becoming more popular?

With each passing year, US households install more residential energy-storage systems as storage prices fall and the value increases. These residential storage systems could be surprisingly valuable to local grid operators.

Is residential energy storage outpacing expectations?

The rapid growth of residential energy storage is outpacing expectations. While larger batteries are also critical segments of the energy-storage market, household systems will likely become important assets sooner than many expect.

Are residential energy-storage systems a good investment?

Already, residential energy-storage systems are attractive for more than 20 percent of US households (Exhibit 3). That market should expand significantly as manufacturers drive down the cost of residential batteries and installers gain the experience and scale to cut installation costs.

Can residential energy storage be integrated?

Annual installations of residential energy-storage capacity could exceed 2,900 MWh by 2023. The more residential energy-storage resources there are on the grid, the more valuable grid integration may become. So several states are experimenting with grid-integration programs targeted at residential energy storage.

Could residential energy storage make the grid more cost effective?

Residential energy storage, i.e. household batteries, could make the grid more cost effective by improving its reliability, resilience, and safety. However, this depends on resolving delicate commercial and policy issues among retail battery providers, utilities, and regulators.

Will residential energy-storage growth continue?

As a result, we expect continued strong residential energy-storage growth. Annual installations of residential energy-storage capacity could exceed 2,900 MWh by 2023. The more residential energy-storage resources there are on the grid, the more valuable grid integration may become.
