SEIA Praises Gov. Sherrill After Signing Of A4529/S3819, Advancing Grid Resilience And Lower-Cost Power In New Jersey

Governor Mikie Sherrill has signed A4529/S3819, a new law that broadens which transmission-scale energy storage projects can receive support through New Jersey’s state incentive program. This program is designed to accelerate the growth of energy storage across the state, and the bill advanced with strong bipartisan backing. By expanding eligibility, New Jersey aims to encourage more large-scale storage development that can strengthen the electric grid and help manage rising energy needs.

Sara Birmingham, vice president of state affairs at the Solar Energy Industries Association, issued a statement supporting the new law. She noted that Governor Sherrill entered office with a commitment to reduce energy costs for residents, and this legislation takes an important step toward that goal. According to Birmingham, allowing more transmission-scale storage projects to qualify for incentives will improve grid resilience and help shield ratepayers from swings in natural gas prices.

She also emphasized that energy storage is becoming essential for keeping electricity costs down and meeting growing demand in New Jersey. Storage systems can be built relatively quickly and make it possible to deliver low-cost solar power to the grid when it is most needed. This reduces the state’s reliance on expensive gas peaker plants, which typically drive up electricity prices during peak hours.

Birmingham expressed appreciation to Governor Sherrill, Assemblymember DeAngelo, Senator Smith and Senator Burzichelli for their leadership in advancing policies that support the state’s long-term energy reliability. She added that companies in the energy storage sector are prepared to expand their work in New Jersey and supply dependable, affordable power to communities across the state. According to a recent report from SEIA and Wood Mackenzie, solar and battery storage projects made up 79% of all new grid power capacity added across the United States in 2025.
