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.
Key Assets We Handle
Gas Collection Systems
Landfill gas collection headers, wellheads, blowers, and related infrastructure
Compression & Injection
Pipeline-quality compression and gas injection facilities
Interconnection Infrastructure
Utility interconnection, metering, and protective relay equipment
Conditioning & Cleanup Equipment
Dehydration, CO2 removal, siloxane removal, and gas purification systems
Generation Equipment
Reciprocating engines, generators, and power conditioning equipment for electricity generation
Control & Monitoring Systems
SCADA, remote monitoring, and data acquisition equipment
Common Assessment Challenges
.png){kind=small}
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
Where We Operate
How PTP Helps
.png)
Emerging Asset Expertise
PTP stays current on assessment methodologies and precedents as they develop for RNG and biogas facilities.
Collection System Modeling
We document declining gas production curves and collection efficiency to support reduced assessments over facility life.
Regulatory Incentive Analysis
We analyze how RIN, LCFS, and other regulatory incentives should be reflected (or not) in property value determinations.
Income Approach Analysis
We build facility-specific income valuations using gas production data, RNG pricing, and regulatory incentive structures.
Equipment Cost Analysis
We apply current equipment pricing to verify and challenge replacement cost estimates for gas conditioning and cleanup systems.
