As RNG projects scale, operators need reliable SCADA systems to manage complex facilities.We break down the most common platforms used in the industry and how teams select them.


FactoryTalk is one of the most widely used SCADA platforms in North American industrial automation.
Many RNG plants rely on Allen-Bradley PLCs, making FactoryTalk a natural choice due to its tight integration with Rockwell control hardware.

Ignition has rapidly become one of the fastest-growing SCADA platforms in the industrial automation sector.
Unlike traditional SCADA systems, Ignition is built around web-based architecture, making it well suited for remote monitoring and multi-site operations.

GE’s iFIX platform has long been used in industrial process monitoring.
In RNG facilities, it is often deployed in plants that require strong data historian capabilities and integration with existing industrial automation infrastructure.

AVEVA’s System Platform (formerly Wonderware) is widely deployed in industrial automation environments.
The platform is known for strong visualization and process monitoring capabilities, making it common in facilities that require detailed operational dashboards.

VTScada is frequently used in infrastructure monitoring environments such as water utilities and gas distribution networks.
Some RNG operators deploy VTScada for remote monitoring of distributed digester systems.
Selecting the right SCADA platform for an RNG facility depends on several operational and technical factors. While most SCADA systems provide similar core functionality, operators typically prioritize compatibility, scalability, and data accessibility.
Most RNG plants rely on programmable logic controllers (PLCs) to control equipment such as digesters, gas upgrading systems, compressors, and pipeline injection infrastructure.
As RNG portfolios expand, many operators manage multiple facilities across different regions.
In these cases, centralized monitoring becomes increasingly important. Platforms such as Ignition and FactoryTalk are commonly used to monitor multiple RNG plants from a single operations center.
Operators often spend hours each day interacting with SCADA screens, especially in facilities where digesters, upgrading systems, and compressors must be monitored continuously. When interfaces are poorly designed or cluttered, it becomes much harder to identify problems quickly.
The RNG industry is still relatively early in its digital transformation.
Most facilities today rely heavily on SCADA systems that were originally designed for industrial process control, not for portfolio-level operational insight.
As operators scale to dozens of plants, a new category of software is beginning to emerge on top of SCADA systems.
These platforms focus on:
Rather than replacing SCADA, these tools use SCADA data to provide higher-level operational intelligence across multiple plants.
For operators managing growing RNG portfolios, this additional software layer is becoming increasingly important.
