Distributed energy storage facilities in the US are set to join wholesale markets and compete to provide grid services after what’s described as the “single most important act” for the energy transition so far.

The United States Court of Appeal in the District of Columbia ruled last week against petitioning from the National Association of Regulatory Utility Commissioners and others which sought to prevent Federal Energy Regulatory Commission Order 841 from passing.

In doing so and allowing Order 841 to pass, distributed energy storage units can now compete with other assets, including fossil fuel resources, to provide grid services in wholesale markets.

FERC chairman Neil Chatterjee lauded the decision when it was handed down late last week, adding his consideration that it would be regarded as the “single most important act we could take to ensure a smooth transition to a new clean energy future.”

“…I’m extremely pleased that the DC Circuit denied the petitions challenging Order 841 on jurisdictional grounds and upheld our orders on the merits. The court found our actions to be well within our statutory authority,” Chatterjee said, adding that Order 841 and removing barriers for energy storage technologies had long been one of his top priorities as FERC chairman.
