Coal

METALLURGICAL VS. THERMAL COAL: A CRITICAL DISTINCTION

It's essential to differentiate between thermal and metallurgical coal when discussing energy and environmental policies. Virginia's coal industry primarily produces metallurgical coal, which is used for manufacturing processes such as steel production, not thermal coal, which is burned and used for electricity generation or as a heat source. This distinction is often misunderstood, leading to misconceptions about the state's coal industry and its environmental impact.

LIMITED ROLE IN ELECTRICITY GENERATION

As of 2024, coal accounted for only about 4% of Virginia's in-state total electric generating capacity. This represents a significant decline from previous decades and was primarily driven by lower-cost energy alternatives while also reflecting Virginia's continued pursuit of cleaner energy sources such as natural gas, advanced nuclear, and renewables.

METALLURGICAL COAL: VIRGINIA'S PRIMARY COAL PRODUCT

Virginia ranks 12th among coal-producing states in the U.S., with a production of approximately 10.4 million short tons in 2023 (an estimated market value of $2.19 billion). Most of this coal is metallurgical grade, used in steel production or other manufacturing processes. Virginia's high-quality bituminous coal is particularly valued in the global steel industry for its high carbon content and its lack of impurities.

ECONOMIC IMPORTANCE OF METALLURGICAL COAL

The metallurgical coal industry remains a significant economic contributor in Virginia, particularly in the southwestern region of the state. Buchanan, Dickenson, Russell, Tazewell, and Wise rely on coal mining as a key economic driver, providing jobs and supporting local economies. The Port of Hampton Roads serves as a critical export hub for this high-quality coal, facilitating its transportation to international markets.

Energy Storage

BATTERY STORAGE

Battery storage technology is gaining traction in Virginia as the state expands its renewable energy capacity. Batteries store excess energy generated from intermittent sources like solar and wind, ensuring a stable electricity supply even when these sources are not producing power.

Key initiatives in Virginia include pilot projects exploring advanced battery technologies such as lithium-ion and iron-air systems. These projects test the feasibility and effectiveness of different storage technologies in Virginia's specific energy landscape. The governor's all-of-the-above energy plan encourages the development of energy storage resources as part of a comprehensive energy strategy.

PUMPED HYDRO STORAGE

Pumped hydro storage is another critical energy storage technology used in Virginia. It involves moving water between two reservoirs at different elevations to store and generate electricity. During periods of low electricity demand, excess energy is used to pump water to the upper reservoir. When demand is high, the water is released back to the lower reservoir, generating electricity as it flows through turbines.

Virginia is home to the Bath County Pumped Storage Station, one of the largest facilities of its kind in the world (fun fact: it's been called "the largest battery in the world"). This facility plays a significant role in stabilizing the grid, providing a reliable source of energy that can be quickly dispatched during peak demand periods. Pumped hydro storage complements battery storage by offering long-duration energy storage, which is essential for maintaining grid stability.

benefits

  • Grid Stability: Helps balance supply and demand, especially during peak usage periods.
  • Renewable Integration: Facilitates greater integration of intermittent renewable energy sources.
  • Resilience: Provides backup power during outages, enhancing overall grid resilience.

challenges

  • Cost: Initial investment costs for battery storage can be high, though prices are decreasing.
  • Technology Limitations: Current battery technologies have limited duration.
  • Environmental Concerns: Proper disposal and recycling of batteries need to be addressed.

Hydroelectric

CURRENT STATUS & CONTRIBUTION

Hydroelectric power plays a modest but important role in Virginia's diverse energy mix. Hydropower's reliability and ability to quickly respond to fluctuating energy demands make it a valuable component of the state's energy portfolio.

benefits

Hydroelectric power offers several advantages as part of Virginia's all-of-the-above energy strategy.

  • Renewable and Clean: Produces minimal greenhouse gas emissions during operation.
  • Reliability: Generates electricity consistently, providing baseload power to the grid.
  • Grid Stability: Quickly responds to changes in electricity demand, helping to balance the grid and integrate intermittent renewable sources like wind and solar.

challenges

While hydroelectric power is valuable for Virginia's energy mix, its expansion faces certain limitations:

  • Environmental Concerns: The construction of new large-scale hydroelectric dams can significantly impact river ecosystems and fish habitats.
  • Limited Growth Potential: Most suitable sites for large hydroelectric projects in Virginia have already been developed, limiting potential expansion.

Every hour and a half, enough sunlight hits the earth that it could power the entire world for one year. The trick is capturing all of that potential energy and converting it into usable, reliable power. Watch the video below to learn more about we capture and convert Virginia's sunshine into usable energy for our communities.

Biomass

CURRENT STATUS & CONTRIBUTION

Biomass energy plays a modest role in Virginia's diverse energy landscape, contributing to the state's renewable energy portfolio and supporting its commitment to an increasingly clean energy future. As of 2024, biomass accounts for approximately 4% of Virginia's in-state total electric generating capacity, providing a valuable source of renewable power that complements other clean energy sources in the state's all-of-the-above energy strategy.

Virginia utilizes various biomass sources for energy production, including wood waste from timber operations, municipal solid waste, landfill gas, and agricultural residues. Notable biomass facilities in Virginia include those operated by Dominion Energy, which have transitioned some coal-fired plants to biomass, utilizing waste wood from timber operations to generate electricity.

PUMPED HYDRO STORAGE

Pumped hydro storage is another critical energy storage technology used in Virginia, accounting for approximately 10% of the total in-state electric generating capacity. It involves moving water between two reservoirs at different elevations to store and generate electricity. During periods of low electricity demand, excess energy is used to pump water to the upper reservoir. When demand is high, the water is released back to the lower reservoir, generating electricity as it flows through turbines.
