As electricity demands grow, additional transmission infrastructure is required to ensure all Maryland residents and businesses can access reliable, affordable energy.

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.

A 2025 Evergreen Collaborative analysis showed that investments in transmission lines would make electric delivery more efficient, reducing the bills of consumers.

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.

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.
