On-site residential and commercial energy storage systems were deployed in the 2017 quarter, the most deployed in the quarter, with an estimated 591 MWhours (MWh)

In addition, the Smart Power Alliance reported a 72% utility plan

Fortunately, in an era of extreme weather, this trend may have a greater impact on utilities and consumers.
Combining energy storage with distributed power generation can protect critical infrastructure, help businesses stay open and keep lights on during power outages caused by severe storms.

Residential customers.
California, Indiana and Ohio utilities added the most energy storage last year, with Illinois, Pennsylvania, Texas and Hawaii listing the most cumulative energy storage deployments.
This pace is accelerating, according to GTM Research.

"This technology no longer sees storage as a competitor to demand, but as a way for utilities to expand relationships with customers and meet changing needs that are increasingly included in extreme weather
Extreme weather has created a huge demand for power grid resilience. To say the least, the impact of Hurricane Harvey on Texas's energy infrastructure is enormous.
During the peak impact of the storm, about 300,000 customers were cut off, and while the three major utilities in the area kept restoring their services 24 hours a day, they expected the rural areas to be No.
As of September 5, two major transmission lines and approximately 7,500 MW of basic-load power generation capacity are still in use, sufficient to serve approximately 375,000 households.
The threat of extreme weather disruption is even more serious for Hurricane Irma, the most powerful hurricane ever in the Atlantic Ocean.
In Puerto Rico, where the storm hit, more than 1 million residents lost power, officials warned that power outages in parts of the island could last for months.

The Level grid infrastructure is both vulnerable to extreme wind and flooding, and a partial outage of the grid can cause chain failures because each component is interdependent.
These infrastructure disruptions have a significant impact on the economy. On-

Due to the reduction of technical costs,

During Harvey, site generation and storage were still running despite record flooding.
These systems rely on natural gas to operate, leaving them out of the financial reach of small businesses and homeowners.
By contrast, solar energyplus-
Storage projects are getting cheaper and can generate revenue by sending excess power back to the grid, without refueling, and will continue to generate power on its own-usually without maintenance.
Unlike floods, the risk of historical storms does not subside.
Due to greenhouse gas emissions, warming of atmospheric and ocean temperatures means increased rainfall due to increased humidity in the air and increased storms due to rising sea levels.
These two factors have exacerbated Harvey's influence in Texas-The water level is about half an foot higher than it was a few decades ago, warming 1 degree-scientists say, warm air and sea make Irma stronger.
Fortunately, the storms of the past provide lessons for the future, and the lessons of the storms of the past provide utilities and their customers with clues to improve the resilience of the grid.
During the super storm Sandy, 6 million people in 24 states lost power, causing $50 billion in losses to customers.

With every "historic" storm that hits the United States, demand for local distributed energy and micro-grids is increasing. S.
But advances in technology and falling prices mean energy storage has filled the gap well.
By adopting new technologies and clean energy to generate electricity, utility companies can improve their bottom line while improving the resilience of their service communities.
