Battery storage and small-scale solar played a crucial role in maintaining the reliability of New England's electric grid during a significant heat wave in late June, potentially saving customers millions of dollars, according to a recent analysis.
As temperatures surpassed 100 degrees Fahrenheit, and humidity levels rose, the demand for electricity peaked at 26,000 megawatts on June 24, the highest level since 2013.
Small-scale solar, predominantly owned by private entities and homeowners, helped meet this demand, consequently reducing costs for all electric customers. Additionally, batteries were instrumental in minimizing the duration of peak electricity prices in the evening.
Heat waves like the one in June not only strain the grid but also increase electricity costs as people resort to energy-intensive cooling methods. The use of small-scale solar and batteries helped alleviate this pressure by shifting peak demand to later hours, ultimately saving consumers money.
An analysis by the Acadia Center estimated that these initiatives could have saved consumers over $19 million and prevented New England from breaking its peak demand record.
Both the Acadia Center and ISO New England emphasized the significant role of power storage in ensuring grid stability during such extreme weather events.
Batteries, whether at residential or utility scale, store excess power when it is abundant and inexpensive, allowing grid operators to utilize it during peak demand periods, ultimately reducing costs for consumers.
With the increasing adoption of battery storage in New England, grid operators foresee a reduced reliance on fossil fuels during peak periods, paving the way for a more sustainable energy future.
