The Benefits of Competitive Transmission

Competitive electric transmission policies—rules that open transmission planning, construction, or ownership to competition rather than relying on a single incumbent utility—can provide several advantages for electricity systems, consumers, and regional reliability. Key benefits include:

Lower Costs for Consumers

  • Competitive bidding for transmission projects often drives down construction and financing costs compared with sole-source utility projects.
  • Independent transmission developers may bring innovative designs or lower-cost approaches, reducing overall project budgets.
  • With competition, regulators have more price benchmarks, making it easier to evaluate what is truly cost-effective.

Innovation in Technology and Design

  • New entrants can deploy advanced technologies—such as dynamic line rating, high-efficiency conductors, grid-enhancing technologies (GETs), and HVDC solutions.
  • Competition encourages utilities to innovate as well, rather than relying on legacy transmission practices.

Improved Reliability and Resilience

  • Diversifying who can build and operate transmission reduces dependence on a single entity’s system.
  • Competitive processes may push for solutions that enhance grid resilience, like networked HVDC backbones or better monitoring.

Faster Project Development

  • When incumbent utilities face limited incentives to build lines that reduce their own market power, development can stall.
  • Opening projects to competitive developers can accelerate construction, especially when the incumbent faces capacity or capital constraints.

Reduction of Utility Monopoly Market Power

  • Incumbent utilities sometimes have incentives to block or delay projects that would increase cross-regional power flows and reduce congestion rents.
  • Competitive transmission policies help mitigate conflicts of interest by enabling independent entities to advance needed lines.

Better Regional Coordination

  • Competitive frameworks often come with clearer processes for regional planning, benefits evaluation, and open solicitation.
  • This can yield transmission portfolios that better support interregional power sharing, renewables integration, and reliability.

Support for Clean Energy Integration

  • More efficient long-distance transmission helps integrate renewables from high-resource areas, which tend to be remote.
  • Competition can spur market-driven development of lines that support decarbonization at lower cost.

Transparency and Accountability

  • Improves oversight and reduces cost overruns
  • Detailed proposals
  • Independent cost estimates
  • Clear performance metrics

Case Studies Showing Benefits of Competitive Transmission

The Brattle Group — broad analysis of competitive planning savings

In a major study of competitive transmission planning under FERC Order 1000, Brattle found that winning bids in competitively solicited transmission projects have often come in ~40% below the initial cost estimates. Brattle+2Brattle+2

The same analysis argued that if competitive procurement were applied more broadly (beyond the small share of projects that currently use it), U.S. consumers could realize about $8 billion in benefits over just five years. Brattle+2TDWorld+2

The report highlights that competition can foster innovation in design and cost-control mechanisms, including cost caps and more efficient financing or capital structures. Brattle+1

Specific Transmission Projects with Documented Savings or Benefits

Crossroads – Hobbs – Roadrunner 345kV Competitive Upgrade Project (New Mexico, under Southwest Power Pool, SPP): This competitively-awarded project reportedly delivered $84 million in savings to consumers compared with non-competitive cost expectations. electricitytransmissioncompetitioncoalition.org

Wolf Creek – Blackberry transmission line (Kansas–Missouri): According to proponents, one competitive bid for this 345 kV line produced a savings of about $58 million compared to more conventional (non-competitive) alternatives. Cato Institute+1

Harry Allen – Eldorado line (California, under California Independent System Operator, CAISO): This project was selected competitively and — by some accounts — completed under budget with cost-savings estimated “up to 29%” compared with non-competitive projections. electricitytransmissioncompetitioncoalition.org+1

Artificial Island Project (New Jersey, under PJM Interconnection): This high-profile transmission project reportedly brought large savings to consumers — some estimates put the benefit at hundreds of millions of dollars, thanks to competitive bidding among many proposals. electricitytransmissioncompetitioncoalition.org+2Utility Dive+2
