From July 2025 through June 2026, Maryland relied on net electricity imports for about 39% of its consumption, making imports its largest supply category. Locally generated low-carbon electricity supplied roughly 31%, slightly more than fossil-fueled electricity at 29%. Nuclear led clean electricity production, supplying about 22% of consumption, followed by solar at 5%, hydropower at 2%, and wind at 1%. Solar’s contribution was split almost evenly between behind-the-meter systems and utility-scale facilities. Among fossil fuels, gas supplied about 24% of consumption, coal 4%, and oil 1%. The figures do not identify the electricity mix behind imports, so imports cannot be classified as entirely clean or fossil-fueled.

Is Electricity Growing in Maryland?

Electricity consumption per person is growing modestly in Maryland. The latest 2026 figure reached about 10,736 kWh per person, exceeding the previous record of 10,665 kWh in 2025 by 71 kWh, or roughly 0.7%. Low-carbon electricity generation also set a record, reaching 3,342 kWh per person—94 kWh, or nearly 3%, above the 2025 record. Clean generation therefore grew faster than consumption on a per-person basis, an encouraging development. Sustaining and accelerating this growth would help meet additional electricity demand from electrification and AI.

Suggestions

Maryland should expand its existing nuclear generation, which already anchors its low-carbon electricity supply, while accelerating rooftop and utility-scale solar. Nearby examples offer useful benchmarks: nuclear supplies about a third of electricity generation in the US state of New Jersey, while the US state of South Carolina gets more than half from nuclear. France, at roughly two-thirds nuclear, provides another example of a substantial clean electricity backbone. For solar, Maryland can learn from the US state of Maine, where solar supplies about 18% of generation, and the US state of California, where it supplies almost a third. These shares concern generation within those regions, rather than Maryland’s consumption-based shares. Investment in clean generation and grid connections would help Maryland strengthen local supply and reduce reliance on fossil fuels, cutting climate-changing emissions and air pollution.

History

The supplied history covers 2024 through 2026 and shows modest, uneven progress in low-carbon electricity generation. Nuclear generation fell by 0.3 TWh in 2024, then recovered by 0.1 TWh in each of 2025 and 2026, leaving it slightly below its 2023 level. Wind delivered steady gains of 0.1 TWh each year. Hydropower was unchanged in 2024 before declining by 0.3 TWh in 2025 and another 0.2 TWh in 2026, while biofuels generation remained unchanged throughout. Overall, these listed sources recorded a net decline of 0.3 TWh across the three years—a disappointing result that reinforces the importance of faster nuclear and solar expansion. Solar’s historical changes are not provided, so these figures do not establish the trend for all low-carbon generation.
