Energy Reliability

Energy reliability means ensuring that electricity is available whenever and wherever it is needed, without interruption. It is a critical part of maintaining economic stability, public safety, and everyday life. However, the U.S. electric grid is facing increasing challenges due to rising demand, aging infrastructure, and the retirement of key power plants. Understanding these challenges and the government’s efforts to address them helps explain the importance of energy reliability for all Americans.

Rising Electricity Demand

Demand for electricity is growing rapidly, driven especially by the expansion of artificial intelligence data centers and increased electrification of vehicles and buildings. Data centers alone consume about 4.4% of U.S. electricity today, with projections reaching 12% by 2028. This surge puts significant pressure on the grid, which must handle higher peak loads and maintain continuous service even during extreme weather events.

Aging Infrastructure and Plant Retirements

Much of the nation’s power generation and transmission equipment is aging, with many components near or beyond their intended lifespan. At the same time, over 100 gigawatts of coal and natural gas power plants are planned for retirement by 2030, while only a fraction of new reliable, dispatchable generation is expected to come online. This gap threatens the grid’s ability to meet demand reliably, increasing the risk of blackouts.

Government Action to Protect the Grid

The federal government is actively working to strengthen the electric grid’s reliability and security. The White House Plan to Protect Power Infrastructure outlines strategies to modernize the grid, improve coordination among operators, and invest in new generation capacity. These efforts aim to prevent a projected 100-fold increase in blackout risks by 2030 and ensure the grid can support America’s growing technological and economic needs.

Regional Risks and Investment Needs

Certain regions, such as those served by PJM, ERCOT, and other major grid operators, face heightened vulnerabilities due to concentrated demand and aging facilities. In response, utilities plan to invest over $200 billion in 2025 to upgrade transmission and distribution systems. Balancing infrastructure replacement with expanding capacity is essential to maintain a reliable and resilient electric grid for the future.
