Perennial Energy

What Perennial Energy does

Perennial Energy (PEI), founded in 1980 and headquartered in West Plains, Missouri, is a privately held LLC that designs and manufactures biogas processing systems and equipment for the landfill, agricultural, municipal wastewater treatment, industrial/mining, and renewable natural gas (RNG) markets across the United States. The company engineers pre-engineered, pre-packaged, factory pre-tested systems including utility flares (up to 100:1 turndown ratio), enclosed ground flares, thermal oxidizers, shrouded and Ultra Low NOx flares, biogas conditioning/compression skids, H2S and siloxane removal systems, and mobile/rental flare units. These systems incorporate integrated digital controls (PLC, VFD motor control, touch panel interfaces) and in-house UL Approved electrical control panel manufacturing, with verified destruction efficiencies of 98% NMOC and 99% VOC and emissions compliance to EPA CFR 40 Section 60.18 and SCAQMD Rule 1118.1.

Revenue is generated through two streams: equipment sales of pre-engineered guaranteed systems, and aftermarket parts and services including preventative maintenance, control panel/PLC upgrades, equipment startup, operator training, instrument calibration, and field services. Go-to-market is direct enterprise sales through a small team led by a VP Sales and Marketing and sales engineers, supplemented by industry tradeshows (Biogas Americas, SWANA regional symposiums), a LinkedIn and Facebook presence, and a website with downloadable product brochures. Pricing is quote-based and not publicly disclosed. Notable customers include the City of Arlington (Texas), Renovar Arlington Ltd., CH Four Biogas, and the San Antonio Landfill, and the company's Arlington Renewable Gas Facility equipment was recognized as the American Biogas Council's 2019 Innovation of the Year.

Core offering

Perennial Energy (PEI) is a design and manufacturing company that builds pre-engineered, guaranteed biogas processing systems and gas destruction equipment for landfill, agricultural, municipal wastewater treatment plant (WWTP), RNG, and industrial customers. Its portfolio includes utility flares, enclosed ground flares, thermal oxidizers, blower and compressor skids, dehydration/chiller skids, H2S and siloxane removal systems, and integrated UL Approved PLC and touch-panel control systems, all factory pre-tested and delivered as single-source systems.

Product overview

Perennial Energy (PEI) is a design and manufacturing company specializing in biogas processing systems and equipment for the landfill, agricultural, municipal wastewater, and industrial markets. The company's product portfolio centers on two interconnected systems: Biogas Processing Systems (Compressor Skids, Blower Skids, Dehydration Systems, Chiller Skids) that extract, condition, and treat biogas; and complementary flare systems (Enclosed Ground Flares, Utility Flares, Thermal Oxidizers, Shrouded Utility Flares, Ultra Low NOx Flares) for gas destruction and combustion. These core products are offered alongside ancillary systems including H2S Removal Systems, Siloxane Removal Systems, Mobile Flare Systems, and Rental Flare Systems. All systems feature integrated digital control systems with PLC, VFD motor control, and touchscreen interfaces, and are designed as pre-engineered, pre-packaged, pre-wired, and factory pre-tested solutions.

Functional benefit

Products and services

• Biogas Processing Systems Pre-engineered systems including compressor skids, blower skids, dehydration systems, and chiller skids that extract, condition, and treat biogas from landfills, digesters, and other sources, providing inlet/discharge pressure control and gas stream moisture removal for landfill, agricultural, municipal WWTP, RNG, and industrial customers.
• Enclosed Ground Flares Enclosed combustion devices meeting air quality regulatory requirements for maximum NOx and CO emissions and minimum destruction/removal efficiencies (DRE), with low noise, zero rumble, and low manifold/burner back pressures, used for landfill gas destruction and other high-emission-control applications.
• Utility Flares Candlestick-style flares with up to 100:1 turndown ratio (minimum 10 SCFM) for landfill or digester biogas destruction, meeting EPA CFR 40 Section 60.18 requirements and providing high-efficiency combustion and odor control for landfill and digester operators.
• Landfill Gas Flares Specialized flares for landfill gas destruction with up to 100:1 turndown ratio, designed to maintain constant and stable inlet vacuum on the well field and equipped with fully redundant blower systems for landfill gas collection and control.
• Shrouded Utility Flares A shrouded version of the utility flare that hides the flame for deployment in populated areas while maintaining the same destruction efficiencies as the standard utility flare, used for RNG projects and coal mine methane applications.
• Thermal Oxidizers Combustion systems meeting air quality regulatory requirements for maximum emissions and destruction efficiencies, with typical applications including CO2 waste gas destruction from RNG upgrade systems and siloxane removal system regeneration gas, used at landfills and RNG facilities.
• Ultra Low NOx Flares Low-emission flares engineered to comply with SCAQMD Rule 1118.1 for Non-Refinery Flares, targeting very low nitrogen oxide (NOx) emission levels for environmentally regulated air districts.
• H2S Removal Systems Engineered systems designed to remove hydrogen sulfide (H2S) from biogas streams, supplied to landfill, agricultural, RNG, and industrial customers as part of biogas processing solutions.
• Siloxane Removal Systems Systems that remove siloxanes from landfill gas to protect downstream engines, gensets, and other equipment from silicone-related damage at landfill and biogas processing sites.
• Biogas Conditioning / Compression Systems Pre-engineered, pre-packaged systems for extracting and processing waste gases, including compressor skids, blower skids, and chiller skids with gas dehydration and temperature conditioning, conditioning biogas for pipeline transport, engine fuel, or boiler end uses.
• Mobile and Rental Flare Systems Portable and rental flare systems providing temporary or mobile flaring solutions for landfill, industrial, and digester operators needing short-term gas destruction capability.
• Aftermarket Parts and Service Replacement parts, preventative maintenance programs, control panel and PLC upgrades, equipment startup, operator training, instrument calibration, and field services supporting installed PEI equipment at landfill, agricultural, municipal WWTP, RNG, and industrial sites.
