Facts & Figures
60%
The amount Maryland energy bills could increase by 2036 without critical grid improvements
WHY THAT MATTERS
Maryland households could save $546 a year on average with the right infrastructure improvements.
40%
The percentage of Maryland’s electricity that is imported from other states
WHY THAT MATTERS
As electricity demands grow, additional transmission infrastructure is required to ensure all Maryland residents and businesses can access reliable, affordable energy.
-4,400MW
The net loss of in-state electric power generator output since 2018
WHY THAT MATTERS
Maryland has had a net loss of 4,400MW of in-state electric power generation since 2018 – enough energy to power 3.5 million homes. Maryland has become less energy independent since 2018, and new, large-scale energy generation projects have not materialized. Electric delivery mechanisms from out-of-state – primarily transmission lines – must be strengthened to keep up with Maryland’s growing energy needs.
$546
The estimated amount of money Maryland households could save each year from improved transmission lines.
WHY THAT MATTERS
A 2025 Evergreen Collaborative analysis showed that investments in transmission lines would make electric delivery more efficient, reducing the bills of consumers.
67%
of Maryland’s electricity infrastructure is over 30 years old. 8% has been completed in the last 10 years.
WHY THAT MATTERS
Aging energy infrastructure costs more to maintain and is less reliable.
1,500TWh
Expected power needed to charge electric vehicles in the United States by 2050.
WHY THAT MATTERS
1,500 TWh is equivalent to the amount of energy that was needed to power the entire residential sector in 2018. As the expansion of green, electric-powered modes of transportation continues, new transmission line infrastructure will be necessary to meet the demand for additional charging capacity.
+128%
The Estimated increase in advanced transmission line infrastructure needed by 2050 to ensure that all Americans have access to reliable, affordable electricity.
WHY THAT MATTERS
Maryland is not the only state that will need to replace and expand its transmission line infrastructure. Wider technology use, such as AI and electric cars, will require Americans to have substantially more access to reliable, affordable energy.
40%
Maryland energy demand growth expected by 2039
WHY THAT MATTERS
The expansion of electric vehicles, advanced home appliances, and developing industries will only stress our aging grid further.
