This Weblog is a part of NRDC’s Yr-Finish Sequence Reviewing 2023 Local weather & Clear Vitality Developments.

For greater than a century, our energy grids have served because the spine of a system that has underpinned financial exercise by delivering power to properties, companies, and trade. However the community was designed in a bygone period to ship power from giant, fossil gasoline turbines to close by cities and cities, and we’ve did not improve and modernize the system. Because of this, the facility traces and elements that when purchased prosperity to far-flung rural communities and illuminated fashionable cities are merely lower than the job of managing the surge of latest renewable power or batteries customers are demanding.

Our grid planning and administration should evolve and strengthen because the clear power transition presents new applied sciences, alternatives, and challenges.

Throughout the nation over the following decade, growing shopper demand — consider thousands and thousands of latest EVs on the highway in search of energy, and higher demand for renewables because of utility decarbonization targets and federal and state local weather insurance policies — will change the way in which electrical energy is used. This doesn’t need to be a hurdle. With sensible planning and insurance policies, elevated electrification can function a useful resource that lets customers assist handle the grid.

Towards that backdrop, regulators, grid operators, and coverage makers took necessary steps this 12 months to pave the way in which for badly wanted system upgrades and to deal with a shortage of transmission capability that’s holding again the clear power transition. There are robust challenges forward and far work to be completed. However for the second 12 months working, the U.S. noticed significant progress in how transmission is deliberate, constructed, and configured to accommodate clear power sources which can be very important to assembly local weather targets, enhancing reliability, and delivering worth for customers.

Getting New Sources on the Grid

We have to add new technology and storage capability to the grid to make sure useful resource adequacy — notably because the grid faces life threatening excessive climate occasions which can be changing into extra frequent because of local weather change. The excellent news is that there’s an abundance of fresh power ready to get on-line. Actually, there are about 2,000 gigawatts (GW) of latest assets—primarily renewables and storage—ready to hook up with energy grids throughout the nation. That’s greater than the mixed output of all energy crops working in the US at this time. The unhealthy information is that because of an out-of-date interconnection course of, it now takes greater than 5 years on common for brand new turbines to maneuver from utility to industrial operation. Most tasks by no means get constructed, partially due to the delays.

This 12 months, we made progress on fixing this downside. The Federal Vitality Regulatory Fee (FERC) undertook the first overhaul of nationwide interconnection requirements in 20 years, updating an outdated system that’s slowing the adoption of fresh power to a crawl. An necessary function of the initiative is to require accountability amongst grid operators for bringing new technology on-line. These new guidelines, as soon as applied, will velocity the addition of latest assets by standardizing the interconnection course of throughout all grid areas.  It’s a change that can repay in new clear power expertise and improved grid effectivity and reliability.

FERC additionally continues to think about its April 2022 proposal to replace its transmission planning guidelines. To state the plain, FERC must problem a robust transmission planning rule as quickly as doable that encompasses long-term wants and a number of situations, incorporates all the advantages of transmission, and supplies clear and sure value allocation requirements. FERC also needs to transfer ahead on a long-discussed replace to guidelines that require transmission suppliers to plan for interregional transmission wants and offshore wind.

Including Transmission Capability for Dependable, Reasonably priced, Resilient Vitality

However even when the interconnection queue eases and transmission planning improves, a decade-long slowdown in new energy traces presents one other barrier to new clear power. Since 2014, North America has constructed simply 7 GW of large-scale interregional transmission — high-capacity traces that carry power over lengthy distances which can be important to renewable builders — in contrast with 44 GW in Europe and 260 GW in China.

The Nationwide Renewable Vitality Laboratory final 12 months projected that for the U.S. to realize 100% clear electrical energy by 2035, interregional transmission should double or triple in capability. Researchers at Princeton College say the speed of transmission building should double that of the final decade or 80 % of the potential emissions reductions doable beneath the 2022 Inflation Discount Act by 2030 can be misplaced. It’s hoped that new DOE funding for transmission upgrades and a speedier evaluate course of for brand new traces will result in greater, stronger, smarter energy grids, and that these traces can be constructed extra shortly.

Take into account this troubling information level. Renewable energy installations declined in 2022 — the primary year-on-year drop since 2017 — partially due to delays in connecting tasks to the grid and an absence of transmission traces, based on a report from American Clear Energy. Harmful and extra frequent episodes of utmost climate like winter storms Elliott in December and Uri in 2021, Hurricane Ida in 2021, and Western U.S. warmth waves in 2020 and 2022 have uncovered how the lack to maneuver electrical energy into affected areas compromises reliability, in some circumstances resulting in harmful blackouts.

In addressing transmission, FERC was not alone. In 2023, the U.S. Division of Vitality (DOE) took strides to assist finance new traces.  The DOE introduced it’ll make investments as much as $3.5 billion for grid upgrades in 58 tasks throughout 44 states designed to strengthen electrical grid resilience and reliability. It additionally introduced that it was making as much as $3.9 billion accessible for 2024 and 2025. As well as, the DOE moved ahead with a program that gives federal help to assist construct interregional transmission. In October, DOE dedicated as much as $1.3 billion for 3 transmission tasks throughout six states that can add 3.5 GW of grid capability.

Lastly, DOE is reforming its transmission allowing course of. The division has proposed a rule to determine the Coordinated Interagency Transmission Authorizations and Permits (CITAP) Program, an entity designed to higher coordinate Federal authorizations and environmental opinions of transmission traces. As soon as finalized, this rule ought to streamline federal allowing for transmission tasks which can be urgently wanted to deal with the local weather disaster, enhance reliability, and cut back congestion.

In the meantime, each FERC and DOE have moved ahead this 12 months in implementing federal backstop siting authority, which supplies FERC authority to approve sure energy traces in DOE–designated Nationwide Curiosity Electrical Transmission Corridors when states reject or fail to behave on transmission tasks. In late 2022, FERC issued guidelines on how you can web site the transmission traces, whereas DOE took significant steps to make sure backstop siting authority generally is a highly effective software to get wanted transmission constructed. Which will sound like rather a lot, however not when you think about the dimensions of the problem.

Legislative momentum

There may be additionally rising momentum in Congress on transmission. In 2023, there was an enormous proliferation of legislative proposals that may, amongst different issues, enhance the method of planning for, constructing, and/or paying for transmission, in addition to others that may enhance the method for siting these tasks or encourage the usage of expertise that may make our present grid extra environment friendly.

Sadly, Congress fumbled a possibility to advertise transmission when it failed to incorporate laws within the debt ceiling invoice that may have required transmission planning areas to have the ability to switch a minimum of 30% of their peak demand to one another, successfully requiring them to construct the brand new interregional transmission traces we’d like. As an alternative, Congress ordered up an pointless research of switch functionality between areas. NERC has 18 months to ship the research to FERC, which can finally problem suggestions to Congress.

However, it’s encouraging that Members of Congress more and more acknowledge the necessity for transmission buildout for a clear, reasonably priced, and dependable power system and are pondering creatively about legislative options. This elevated recognition ought to underscore the urgency of the difficulty and be a name to motion for passing laws in 2024.

Trying ahead

NRDC has laid out a transparent path to constructing badly wanted transmission and to upgrading present traces shortly with out compromising bedrock environmental or social justice safeguards via present authorities and guidelines. Utilities, customers, and power markets are keen so as to add wind, photo voltaic, and battery storage to their power portfolios. Delaying this inevitable clear power transition will solely extend the usage of fossil fuels and burden society with much more dangerous emissions and local weather impacts.

The groundwork is being laid for severe momentum on buildout of badly wanted transmission throughout the nation. Growing ranges of regulatory and legislative exercise is an encouraging signal, and we plan to proceed our work advocating for insurance policies that make it simpler to plan and construct the grid we’d like for a clear power future. We’ve got a possibility to make 2024 a banner 12 months for transmission enlargement and grid decarbonization. We should not let this chance go to waste.
