Macro Grid Initiative

The Macro Grid Initiative seeks to expand and upgrade the nation’s transmission network to deliver job growth and economic development, a cleaner environment, and lower costs for consumers. Learn more about The Macro Grid Initiative, an ACORE program.

Transmission Facts & Figures

Access to Clean Energy Resources

More than 25 states, four Canadian provinces, 150 + cities, and countless utilities and corporations, are making ambitious commitments to renewable and carbon-free energy.

According to estimates from the Lawrence Berkeley National Lab, by 2030 state-specific clean energy demand standards are expected to amount to: 600 TWh to 714 TWh. The latter is ~17% of current U.S. retail sales.

Investment in transmission is not keeping pace with renewable energy generation , which is often far from load. Only about 1,300 miles of transmission were completed in 2018 and even less in 2017, compared to the peak of 4,500 in 2013.

ScottMadden’s analysis for WIRES (1/20) finds that without strategic and timely expansion of the transmission infrastructure, the ability of states to meet their clean energy mandates by 2030 may be in jeopardy .

Grid Reliability and Resilience

According to the US Department of Energy in The Smart Grid: An Introduction (PDF, 4.5 MB), outages and power quality issues are estimated to cost American business more than $100 billion on average each year.

By 2030, electrification of transportation and heating sources could increase nationwide annual energy demand by 5% to 15%.

Investment in the electric grid will:

  • Reduce transmission energy losses
  • Reduce congestion due to transmission outages
  • Mitigate extreme events and system contingencies
  • Mitigate weather and load uncertainty

A more robust grid helps protect against and recover from all types of unexpected events, including deliberate attacks on our infrastructure, while a weak and congested grid makes the system vulnerable to disruption.

Economic Development and Consumer Savings

According to a 2019 Brattle Group report for WIRES, $30–$90 billion in incremental transmission investments will be necessary in the U.S. by 2030 to cost-effectively meet the changing system needs due to electrification, with an additional $200–$600 billion investment required between 2030 and 2050.

In a 2011 Report for WIRES, the Brattle Group said a likely annual investment range of $12 billion to $16 billion in transmission through 2030 would stimulate $30 billion to $40 billion in economic activity and support 150,000 to 200,000 full-time jobs per year.

With C$45 billion in planned Canadian transmission investments through 2030, averaging C$5 billion annually over the next several years. This level of Canadian investment will support between 20,000 and 50,000 fulltime jobs annually.

Once operational, the expanded transmission infrastructure will also enable additional economic activity, such as the construction of renewable generation projects, which is estimated to support 130,000 to 250,000 full-time jobs in the U.S. during each year of the projected 20-year renewable generation construction effort.

In a 2018 analysis, London Economics International found that an Eastern Interconnect sample line designed to increase capacity between two regional markets operated by PJM and MISO delivered broad benefits to the economy, workers and consumers in the 3-4 years leading up to the project and in the first 15 years of operation:

  • 4,200 jobs added annually
  • GDP increased by $710M
  • $275M in savings per year for consumers on electricity costs

In addition to these employment and economic stimulus benefits from constructing the facilities and manufacturing equipment, strengthening of the transmission grid provides other important economic benefits, including:

  • Reduced transmission losses, production cost savings, enhanced wholesale power market competition and liquidity, and associated wholesale power price reductions
  • Increased reliability, insurance against high-cost outcomes under extreme market conditions, and increased flexibility of grid operations
  • Generation investment cost savings and access to lower-cost renewable generation
  • Increased federal, state, and local tax income
