Landfill Gas-to-Energy & RNG Facility Construction

A Design-Build EPC Contractor for Landfill Gas-to-Energy and RNG

Curington Contracting has been building industrial facilities since 1972 and entered the landfill gas-to-energy (LFGTE) sector in 2007. Since then, our team has built LFGTE power plants, flare stations, gas compression systems and renewable natural gas (RNG) facilities across the United States, from our home base in Ocala, Florida to projects in California, Virginia, Pennsylvania, Mississippi and North Carolina.

Utilities, landfill operators and energy developers bring us in to deliver the whole facility under one accountable builder: site work and foundations, engine buildings and genset installation, gas processing, electrical and controls, then commissioning. Because our O&M division also operates facilities after construction, we build with long-term performance and maintenance access in mind.

Built for Utilities, Landfill Operators & Energy Developers

From 850-kilowatt containerized genset installations to an 8-megawatt, five-engine power plant, we have delivered landfill gas-to-energy projects at nearly every scale.

Every project follows our design-build process, with planning, engineering coordination and construction managed by one team from the first site visit to startup.

Get Started

LFGTE & RNG Construction Services

As a design-build EPC contractor, Curington supports landfill gas-to-energy and RNG projects from early planning through startup, coordinating every trade and specialty vendor so the whole plant comes together on one schedule.

Design-Build EPC Delivery

Engineering coordination, procurement and construction under one contract, backed by an in-house CADD team that takes designs from concept to construction-ready drawings.

Site Work, Foundations & Underground

Clearing, grading, drainage and access roads, plus concrete engine pads, aggregate base and the extensive underground conduit runs every energy plant depends on.

Engine Buildings & Genset Installation

Pre-engineered metal buildings with ventilation, maintenance platforms and overhead cranes, plus crane lifts to set engine-generator packages and connect fuel gas, cooling, exhaust and lube oil systems.

Gas Processing, Compression & Flares

Compression skids and treatment systems that remove moisture, siloxanes and sulfur compounds, along with flare stations that safely burn excess gas when generators are offline.

Electrical, Switchgear & Controls

Switchgear, protective relaying, step-up transformers and SCADA monitoring and controls, coordinated with the local utility to meet its interconnection standards.

RNG Facilities, Commissioning & O&M

Renewable natural gas facilities, systematic testing and startup before the plant goes online, and ongoing operations support from our O&M division afterward.

Why Owners and Developers Choose Curington

Operational Insight

Our O&M division operates facilities after construction, so we know where access platforms belong, which gas treatment tolerances protect the engines, and how operators actually use a control room.

One Accountable Builder

Our design-build process keeps planning, engineering coordination and construction under one roof, with fewer handoffs and one point of accountability.

In-House CADD Team

Our CADD team develops designs from concept to construction-ready drawings in house, which keeps revisions fast and coordinated with the field.

Family-Owned Since 1972

Curington Contracting, LLC is a family-owned Certified General Contractor (CGC014568) based in Ocala, Florida, with industrial construction experience that reaches well beyond energy work.

Frequently Asked Questions About LFGTE and RNG Construction

What does a landfill gas-to-energy facility include?

A typical LFGTE facility includes gas compression and treatment systems that remove moisture, siloxanes and sulfur compounds, reciprocating engine-generators housed in a power-generation building, switchgear and step-up transformers that connect to the utility grid, a flare station for excess gas, and SCADA monitoring and controls.

What is the difference between an LFGTE plant and an RNG facility?

An LFGTE plant burns processed landfill gas in engine-generators to produce electricity. An RNG facility upgrades landfill gas into renewable natural gas instead of converting it to power on site. Curington has built both types of facilities.

Do you build LFGTE and RNG projects outside of Florida?

Yes. Our energy work is national, with completed projects in Florida, California, Virginia, Pennsylvania, Mississippi and North Carolina.

What size landfill gas-to-energy plants have you built?

Our projects range from 850-kilowatt containerized genset installations to an 8-megawatt power plant with five engines.

Can Curington support the facility after construction?

Yes. Our O&M division provides ongoing operations support after a facility is online, and that operating experience shapes how we design and build every plant.

Do you coordinate utility interconnection?

Yes. LFGTE plants feed power to the local grid, so our electrical installations are coordinated with the utility to meet its interconnection standards.
