Unlocking Savings in the U.S. Energy Sector with Advanced Transmission Technologies
Utilities in the United States have a unique opportunity to reshape their business model by transitioning towards advanced transmission technologies (ATTs). Instead of solely focusing on traditional expenditures, these technologies allow utilities to profit by saving costs, ultimately resulting in substantial savings for consumers on their electricity bills—potentially billions each year.
Globally, countries like Belgium, India, and the United Kingdom have successfully implemented ATTs at scale. Similar early efforts in the U.S. have yielded impressive results. For instance, a recent initiative utilizing dynamic line ratings demonstrated a capacity increase of over 50% for merely $45,000 per mile—a fraction (1%) of the cost associated with constructing new transmission lines.
Challenges to Adoption in the U.S.
Despite the clear advantages of ATTs, widespread investment and deployment remain limited in the U.S. One significant barrier is the antiquated regulatory framework governing the electricity market, which often disincentivizes innovative solutions that could optimize efficiency and reduce consumer costs.
Current regulations typically enable utilities to earn profits based on the expensive, capital-intensive projects they undertake. This model encourages utilities to pass on the costs of these large developments to consumers, leading to elevated electricity rates approved by local public utility commissions. As a result, utilities are incentivized to pursue costly investments rather than strategies that save money.
To illustrate, when utilities construct a new transmission mile, they might secure approximately $600,000 annually in profit. In contrast, after deploying the necessary technology for line ratings, this profit drops to about $4,500 per mile. Although state regulatory agencies aim to protect consumer interests, they often lack sufficient information to determine the most effective methods for achieving this goal.
Needed Policy Changes
Addressing these structural roadblocks necessitates action from both federal and state levels. Encouragingly, there is bipartisan potential for reform, as evidenced by progressive moves in states like Minnesota and Montana. However, existing policies remain inadequate.
To enhance the integration of ATTs, several key recommendations can be made:
- Mandatory Use of ATTs: Utility providers should be required to implement ATTs in scenarios where the risks are minimal. The Federal Energy Regulatory Commission (FERC) is contemplating mandating dynamic line ratings for congested transmission lines. Swift action and stronger regulations in this area would facilitate significant improvements.
- Efficiency Standards: The Department of Energy or Congress should introduce standards aimed at enhancing the efficiency of the electrical grid. Approximately 5% of the electricity generated in the U.S. is lost during transmission; utilizing high-performance conductors could potentially reduce these losses by 30%.
- Support for Evaluation: Federal agencies and state lawmakers ought to advocate for the assessment of ATTs by transmission providers. Recent initiatives by FERC signify progress, but further actions are essential to bolster these efforts.
- Financial Incentives: Introducing shared savings incentives could motivate transmission providers to adopt ATTs. The Advancing GETS Act outlines a framework that would allow utilities to earn profits through cost savings, rather than merely through expenditures.
- Investment in Digital Tools: Developing innovative digital instruments to identify opportunities for ATTs will empower regulators to hold agencies accountable. By sharing crucial data on electricity supply and grid infrastructure, researchers could create a “digital twin” of the transmission system to analyze configurations and enhance efficiency.
Effectively navigating the complexities of policy-making often involves difficult trade-offs. Nevertheless, legislation promoting the use of ATTs presents a straightforward solution—expanding the grid’s capacity while delivering reliable savings to consumers. This approach should garner support across the political spectrum.
