The InterSolar North American exhibit kicks off in San Francisco on July 10 this year. InterSolar is the global organization that brings everyone interested in solar power together to network and learn about the latest trends in the industry.
This year, a lot of the exhibitors and attendees will be talking about energy storage technology. According to GTM Research’s Energy Storage Monitor report for the fourth quarter of 2017, storage is the fastest growing segment of the solar market.
There are two basic types of energy storage – front of the meter, commonly known as grid-scale storage, and behind the meter, in which individual property owners and businesses make use of storage options installed on their own premises to better manage onsite solar systems and take advantage of lower utility rates available when demand for electricity is low. GTM reports that many more utility companies are beginning to include energy storage in their long-term planning.
All across America, states are making integrated resource planning a requirement for utility companies, or the companies themselves are including energy storage options in the rate proposals they are submitting to state regulatory agencies.
Looking down the road, GTM Research sees battery storage growing nearly tenfold in the next 5 years, from 295 megawatts in 2017 to 2.5 gigawatts in 2022, of which almost half is projected to be “behind the meter.”
Grid-scale energy storage allows utility companies to even out the flow of electricity sloshing around the utility grid. It will be a vital part of converting the utility industry from one in which a few large generating stations supply power to millions of customers spread over hundred of miles into one that features thousand of power producers who share their electricity locally.
That shift will usher in the era of many smaller microgrids linked by a few long-distance interconnecting transmission lines, which will reduce the cost of building and maintaining such a large energy grid with its many substations and transformers.
