RNG & Landfill Gas-to-Energy Property Tax
Emerging clean energy assets. Evolving assessment practices. PTP stays ahead.
Renewable natural gas (RNG) and landfill gas-to-energy (LFGTE) facilities represent a rapidly growing asset class in Texas — and one where appraisal district expertise is still developing. Without established comparable sales or clear assessment precedents, these facilities are frequently overvalued using cost approaches that ignore income limitations and market realities unique to biogas operations.
Property Tax Partners works with RNG and LFGTE operators to challenge these assessments using gas production data, income-approach analysis, and facility-specific obsolescence studies. We understand the unique characteristics of biogas facilities — including variable gas quality, collection system dependencies, and the relationship between gas production and facility value.
As the regulatory and market environment for RNG and LFGTE continues to evolve, PTP keeps our clients positioned to challenge assessments that don't keep pace with changing economics.
Key Assets We Handle
Landfill gas collection headers, wellheads, blowers, and related infrastructure
Dehydration, CO2 removal, siloxane removal, and gas purification systems
Pipeline-quality compression and gas injection facilities
Reciprocating engines, generators, and power conditioning equipment for electricity generation
Utility interconnection, metering, and protective relay equipment
SCADA, remote monitoring, and data acquisition equipment
Common Assessment Challenges
- Appraisal districts lack established comparable sales and assessment precedents for RNG/LFGTE assets
- Gas production variability is rarely accounted for in cost-based valuations
- Collection system degradation and declining gas quality are not reflected in standard depreciation schedules
- Regulatory incentive structures (RINs, LCFS credits) affect income but are inconsistently treated by appraisers
- Mixed-use facilities (power generation + gas upgrading) require comprehensive multi-asset analysis
How PTP Helps
PTP stays current on assessment methodologies and precedents as they develop for RNG and biogas facilities.
We build facility-specific income valuations using gas production data, RNG pricing, and regulatory incentive structures.
We document declining gas production curves and collection efficiency to support reduced assessments over facility life.
We apply current equipment pricing to verify and challenge replacement cost estimates for gas conditioning and cleanup systems.
We analyze how RIN, LCFS, and other regulatory incentives should be reflected (or not) in property value determinations.
Our Process
- Facility & Production Review
We analyze gas production data, facility design, and current operating conditions to understand the revenue-generating capacity.
- Income Approach Development
We build facility-specific income valuations incorporating production forecasts, gas pricing, and applicable regulatory incentives.
- Cost Analysis
We verify appraisal district cost estimates against current equipment pricing and apply appropriate depreciation.
- Protest & Negotiation
We file protests with comprehensive valuation support and educate appraisal district staff on the unique characteristics of biogas assets.
- Ongoing Monitoring
We monitor gas production trends and market developments to update valuation support as facility performance changes.
Frequently Asked Questions
How do Texas appraisal districts value RNG and landfill gas facilities?
Most districts use a cost approach, which often overvalues these facilities by ignoring production variability, collection system decline, and income limitations. PTP challenges these assessments using income approaches that reflect actual gas production data and market pricing for renewable natural gas.
Do RNG and LFGTE facilities qualify for any Texas property tax exemptions?
Texas provides certain property tax exemptions for pollution control equipment and some renewable energy components. The applicability varies by facility type and specific equipment. PTP analyzes your facility for all potentially applicable exemptions as part of our engagement.
How does gas production decline affect property taxes?
As landfill gas production naturally declines over the facility's life, the income-generating capacity of the collection and processing equipment decreases. However, appraisal districts often maintain cost-based assessments that don't reflect this decline. PTP documents production trends to support assessments that properly reflect declining gas availability.
