US Residential Energy Storage Market Is Developing Rapidly
- Sep 13, 2018 -

US utility companies connected 217 MW / 524 MWh of energy storage projects to the grid in 2017. Although this was driven by utility supply projects, the US Intelligent Power Alliance (SEPA) said that residential energy storage The growth is the strongest.

According to the latest report on the utility energy storage market released by the Smart Power Alliance (SEPA) in 2018, from 2016 to 2017, the increase in residential energy storage capacity increased by 202% in terms of MW, while the growth rate of non-residential energy storage was only 9%. Utilities supply projects have even fallen slightly. In terms of MWh, the growth rate of residential projects is even more impressive, reaching 317%, compared with 105% for non-residential energy storage and 89% for utility supply projects.

Nick Esch, a senior researcher at the Smart Power Alliance (SEPA), said in a statement that lithium-ion batteries have become "unprecedented grid assets."

A report by EnergySage shows that nearly three-quarters of solar power system adopters surveyed last year said they are considering using residential battery energy storage systems.

Esch said many utility companies are trying to deploy centralized residential energy storage systems, fully schedulable solar and battery energy storage systems, and microgrids.

Esch said, “The US energy storage market is still in its infancy. However, national policy actions and regulatory actions are creating opportunities for the energy storage market.” He said that in addition to California and Hawaii, Maryland, Massachusetts, New Jersey, and New York. Nevada is also rapidly deploying more energy storage projects.

The Smart Power Alliance (SEPA) survey report shows that people are very interested in the growth of the residential resource storage market.

“User-side battery storage customers are critical to utility companies, and 64% of companies are interested in it and plan or actively implement it,” the Smart Power Alliance (SEPA) said. Currently, Green Mountain Power has two pilot projects: one project uses Tesla's Powerwall energy storage system, and the other project uses its own equipment to accommodate batteries from four different manufacturers.

The report shows that the cumulative deployment energy capacity of 5,167 systems in the United States is 922.8 MW / 1293.6 MWh.
