KEY POINTS

• Transmission costs in ERCOT rose from $1.5 billion in 2010 to over $5 billion in 2024 and could increase to over $12 billion per year by 2033.
• After adjusting for inflation and overall rising electricity demand, the average ratepayer in the ERCOT region paid 57% more in transmission charges in 2024 than in 2010.
• Texas ratepayers are paying about $1 billion per year to support transmission investments for wind and solar and have paid a total of nearly $15 billion since 2010.
• If current transmission plans are fully executed, the annual cost of transmission in ERCOT will more than double, adding at least $100 per year to the average residential ratepayer’s electric bill.
• Many new transmission projects will primarily serve new data center demand, highlighting the urgent need to revise how transmission costs are allocated among all ratepayers.
