A growing coalition of state utility regulators is seeking to formally recognize renewable natural gas (RNG) as a strategic energy resource, signaling a potential shift in how RNG is positioned within broader state and federal energy planning frameworks.
According to a press release, the Pennsylvania Public Utility Commissioner Kathryn Zerfuss is leading a national effort through the National Association of Regulatory Utility Commissioners to advance a resolution that would elevate RNG within utility and energy policy discussions. The initiative aims to encourage regulators to treat RNG not simply as a niche renewable fuel, but as a component of long term energy security, infrastructure modernization, and decarbonization strategies.
The effort reflects a broader conversation underway across the United States about the role of gas infrastructure in a lower carbon future. While electrification has dominated much of the climate policy debate, RNG advocates argue that existing pipeline systems represent a major asset that can be leveraged to reduce emissions without requiring full system replacement. By substituting fossil natural gas with biogas derived from anaerobic digestion facilities and landfill gas capture systems, utilities can potentially lower lifecycle greenhouse gas emissions while maintaining grid reliability.
RNG markets have been a primary driver of new anaerobic digestion capacity, particularly in dairy manure. Recognition of RNG as a strategic energy resource could influence how state utility commissions evaluate pipeline investments, interconnection policies, cost recovery mechanisms, and long term procurement contracts.
The framing also has implications for food waste digestion. While dairy and landfill-based RNG have historically dominated production volumes, food waste anaerobic digestion projects continue to face financing and interconnection hurdles, according to the American Biogas Council. If regulators adopt a more formal strategic lens, it may open pathways for utilities to incorporate food waste-derived RNG into portfolio planning, particularly where methane reduction goals intersect with waste diversion mandates.
At the same time, the effort is likely to draw scrutiny. Critics of RNG expansion have questioned lifecycle accounting methodologies, methane leakage rates, and the risk of locking in gas infrastructure at a time when some jurisdictions are pursuing building electrification policies. Elevating RNG to “strategic” status may intensify debates over how renewable attributes are measured and valued, particularly across different feedstocks.
The reality is that state regulators play a central role in shaping energy markets. Their decisions influence infrastructure investment, ratepayer costs, and the viability of emerging technologies. For organics recyclers and anaerobic digestion developers, regulatory recognition can materially affect project bankability.
Zerfuss and her colleagues are seeking to build consensus across state commissions nationwide. Whether the effort translates into binding policy changes remains to be seen. But the push itself highlights a maturing RNG sector that is increasingly positioning itself not only as a waste management solution, but as part of the nation’s energy strategy.
