Compared to the prosperity of power battery energy storage and grid connected energy storage, household energy storage in China seems a bit inconspicuous.
The characteristics of household energy storage are small individual scale, scattered layout, and the equipment manufacturers and investors are mainly of small and medium-sized private enterprises.
At the same time, there are limited areas with profitability for home energy storage (HESS), and the overall scale proportion is also small, which has not received high attention in the Chinese energy storage market.

Market Changing
With the continuous advancement and improvement of China’s electricity market, the business model of household energy storage is also quietly changing, and the new policy will also combine household users, lithium battery solar energy storage, grid load aggregators, virtual grids, etc., to provide energy storage off-on grid services for the power market.
As an independent storage system, household energy storage can participate in the power market is an important part of the future power grid, especially medium-sized solar battery energy storage, wind battery energy storage power station, which has better conditions to participate in the auxiliary services or spot market of the power grid, better play the supporting role of the power grid and obtain income, enrich the profit model of household energy storage, and improve the utilization rate of energy storage system.
Broad Future
Household energy storage has the characteristics of more market-oriented operation, the cost and performance of the whole life cycle of energy storage equipment (such as lithium batteries, sodium batteries) is more sensitive, with the decline of the cost of energy storage batteries and other major equipment and the improvement of battery performance, the power market continues to improve, China’s household energy storage market will have a broad space for development.
