Federal regulators have recently approved new rules aimed at expediting the process of connecting wind and solar projects to the electric grid in the US. This move comes as a response to the mounting delays that have become a major hindrance to the development of renewable energy in the country.
Energy companies are currently investing billions of dollars in wind farms, solar arrays, and batteries, driven by federal tax incentives and decreasing costs. However, these projects are facing a significant bottleneck: the challenge of connecting new power plants to existing power lines efficiently and swiftly.
By the end of 2022, over 10,000 energy projects, predominantly wind, solar, and batteries, were awaiting permission to connect to electric grids, marking a substantial increase from 5,600 projects two years prior. The sheer volume has overwhelmed grid operators, resulting in a lengthy approval process, now averaging five years for a power plant compared to a decade ago. Developers have described the current process as dysfunctional.
The Federal Energy Regulatory Commission, which oversees electricity markets, has introduced these new rules to streamline the approval process, known as the interconnection queue.
In the past, grid operators would review power plant proposals one by one, conducting extensive studies to ensure that new projects do not disrupt the existing grid. While this method was suitable for a few coal or gas plants annually, it has proven inadequate for the thousands of smaller wind, solar, and battery projects in the works today.
The new rules necessitate that grid managers study projects collectively and prioritize those closest to the construction phase. Several regional grids are already pursuing this reform. Additional changes include penalties for grid operators who fail to complete studies on time, stricter financial requirements for applicants to filter out speculative proposals, and modifications that facilitate the integration of batteries into the grid.
According to Willie Phillips, the Democratic chairman of the energy commission, “Our transmission policies must keep pace with the rapid changes in the makeup of our nation’s power generation resource mix. We know that long backlogs create uncertainty for everyone and that increases costs for everyone.”
While the reforms are expected to be beneficial, energy developers believe that they will not completely address the most significant challenges obstructing the progress of renewable energy. Melissa Alfano, director of energy markets at the Solar Energy Industries Association, commented, “While this is a decisive step forward, we have a long way to go before we clear the two terawatts of generation and storage that are trapped in the interconnection queue.”
One critical issue faced is the limited spare capacity in existing grids across various parts of the country. This shortage often requires developers to finance costly upgrades before connecting new wind and solar projects. Since 2019, these expenses have nearly doubled in the Mid-Atlantic and Midwest regions. The process of funding these upgrades is chaotic, leading many developers to drop out of the queue due to prohibitive costs, resulting in further delays.
Experts suggest a more effective approach would involve grid operators planning transmission upgrades that benefit a wide range of energy providers and users. This would distribute the costs among a larger group, rather than requiring individual developers to cover the expenses incrementally. While grid operators in California and the Midwest have recently adopted this long-term planning strategy, it remains relatively uncommon.
The Federal Energy Commission has proposed a separate rule that aims to encourage all grid operators to better plan for the expansion of renewable energy. However, this rule, which has yet to be finalized, may encounter challenges as utilities and states often differ significantly in their views on cost-sharing for new transmission.
Recently, Senator Chuck Schumer of New York, the Democratic majority leader, expressed concerns about the adequacy of the commission’s proposed grid-planning rule. He emphasized the critical role the commission plays in the success or failure of transmission rules for achieving the nation’s clean energy objectives.
In the past year, congressional Democrats have increasingly recognized the need to overhaul the nation’s electric grid to effectively combat climate change. Although the Inflation Reduction Act injected substantial funding into clean energy technologies, a recent analysis indicated that half of the climate benefits of the bill could be lost without an accelerated pace of new transmission development to accommodate additional renewable energy.
Negotiations among commission members regarding the grid-planning rule are currently underway. The commission consists of five seats, with two Democrats, two Republicans, and one vacant seat. The previous Democratic chairman stepped down last year after a disagreement with Senator Joe Manchin III, Democrat of West Virginia, concerning gas pipelines.
Mr. Phillips, the commission chairman, expressed a sense of urgency, stating, “We’re trying to get this done as fast as we can. It has always been a top priority.”
