Methane Emissions and Leak Detection
Methane represents a critical concern in natural gas operations, as this greenhouse gas carries approximately 84-86 times the warming potential of carbon dioxide over a 20-year period. Dominion Energy’s gas distribution and transmission systems inevitably experience some methane leakage through aging infrastructure, maintenance activities, and operational processes. Quantifying and managing these emissions remains essential for environmental responsibility.
The company has invested in leak detection technology, including aerial surveys and ground-based monitoring systems. These initiatives aim to identify and repair leaks more rapidly than traditional methods allow. However, environmental groups argue that more aggressive infrastructure replacement and repair schedules are necessary to adequately address this challenge.
Key concerns regarding methane emissions include:
- Aging infrastructure in older service territories with higher leak rates
- Incomplete emissions reporting and verification methodologies
- Insufficient pace of pipe replacement programs
- Limited transparency regarding actual emissions data
- Regulatory gaps in federal methane standards for distribution systems
According to EPA climate change resources, methane management across the natural gas supply chain represents a critical climate mitigation opportunity. Federal agencies continue developing stronger emissions standards and monitoring requirements.
Infrastructure Investment and Modernization
Dominion Energy has committed substantial capital expenditures toward infrastructure modernization, including pipeline replacements, compression station upgrades, and digital monitoring systems.
