Energy Storage Policy And Regulations Shaping The Future

A comprehensive deep-dive into the facts, history, and hidden connections behind energy storage policy and regulations shaping the future — and why it matters more than you think.

The rise of renewable energy has brought with it a pressing need for reliable, large-scale energy storage solutions. As the world transitions away from fossil fuels, policymakers and regulators have been grappling with how to incentivize, mandate, and oversee the development and deployment of these critical technologies. From lithium-ion batteries to pumped-storage hydroelectricity, the policies and regulations shaping the future of energy storage will have far-reaching implications for the global economy, environment, and geopolitical landscape.

The 2008 Federal Energy Storage Mandate That Kickstarted The Industry

In the late 2000s, as renewable energy began to gain serious traction, the United States Congress recognized the urgent need to establish a regulatory framework for energy storage. In 2008, they passed the Energy Policy Act, which for the first time mandated that the Federal Energy Regulatory Commission (FERC) create rules to facilitate the participation of energy storage in the country's electricity markets.

This landmark legislation set off a flurry of activity, as FERC and state public utility commissions rushed to develop new regulations and incentives. The FERC Order 841, issued in 2018, was a particularly significant milestone, requiring grid operators to remove barriers to energy storage participation in wholesale markets.

Lithium-Ion Batteries: From Consumer Electronics to Grid-Scale Storage

While pumped-storage hydroelectricity has been used for large-scale energy storage since the 20th century, the real breakthrough in recent decades has been the rapid advancement of lithium-ion battery technology. Driven by the explosion of consumer electronics, lithium-ion battery costs have plummeted, making them increasingly viable for grid-scale applications.

In 2010, the California Public Utilities Commission became the first US regulator to mandate the procurement of energy storage, requiring the state's three major utilities to deploy a combined 1.3 gigawatts by 2020. This policy proved hugely influential, with numerous other states following suit with their own storage mandates and incentives.

"The California energy storage mandate was a watershed moment. It showed that policymakers were serious about making storage a core part of the future grid." - Dr. Amelia Greiner, energy policy expert at the University of California, Berkeley

The Geopolitics of Energy Storage

As energy storage technologies have advanced, they have also become a critical geopolitical battleground. China, the world's largest producer of lithium-ion batteries, has aggressively promoted domestic battery manufacturing through subsidies and regulations. This has alarmed policymakers in the United States and Europe, who view China's dominance of the supply chain as a potential threat to their energy security and technological leadership.

The Race to Deploy Long-Duration Energy Storage

While lithium-ion batteries have made significant inroads, they are still limited in their ability to provide long-duration energy storage – the ability to discharge power for multiple hours or even days. This gap has sparked a global race to develop alternative technologies, from flow batteries to compressed air energy storage.

Policymakers have been eager to incentivize these "long-duration" storage solutions, recognizing their crucial role in enabling a high-renewables electricity grid. The US Department of Energy, for example, has launched numerous funding programs and technology prizes aimed at advancing long-duration storage.

The Regulatory Challenges Ahead

As energy storage continues to grow in scale and importance, policymakers and regulators will face a host of complex challenges. Issues around grid integration, market design, safety standards, and environmental impact will all require careful consideration and balancing of various stakeholder interests.

One particularly thorny issue is how to properly value the multi-faceted benefits of energy storage – from grid resiliency to emissions reduction. Developing fair and effective pricing mechanisms will be essential to ensuring storage technologies are deployed where they can provide the greatest societal value.
