If you think that the renewable energy supply chain runs on solar, wind, hydro, or some other form of energy alone, think again. Behind utility-sector providers, individual power producers, and even financial instruments used to channel public and private funds into projects lie SCADA systems.  You could say it’s the silent operator making sure everything works harmoniously in the renewable energy ecosystem. 

In fact, SCADA is critical to the seamless functioning of renewable plants producing 5 MW or more energy. Unsurprisingly, global SCADA in the sector is going to grow from USD1.76 billion in 2024 to USD3.56 billion in 2030. 

This article aims to decode evolving SCADA systems and their multifaceted role in optimizing performance, ensuring grid-code compliance, reducing downtime, and maximizing asset availability across the global renewable energy portfolio.

Understanding SCADA Systems

Supervisory Control and Data Acquisition, a.k.a SCADA, is an integrated system architecture built for controlling, monitoring, and managing large-scale industrial systems. It comprises multiple hardware and software components, including: 

1. Human-Machine interfaces that are basically screens for operators
2. Sensors and other field devices that collect real-time data from the plants 
3. Remote units that let operators control and communicate with other mechanical components 
4. Software that connects all the components 

It’s almost like the central nervous system of the human body, where an interconnected system of components drives everything from decision-making to coordination and functional support.  

In a renewable energy production set-up, a SCADA system: 

• Collects real-time data
• Optimizes overall plant performance
• Sends control commands
• Logs events and alarms
• Supports operational decision-making 
• Helps maximize resource utilization

SCADA systems are deployed across solar PV, wind, BESS (Battery Energy Storage Systems), and hybrid renewable energy plants. 

The 4 Layers of SCADA Systems   

But what does an interconnected system of software and hardware really imply? Typically, SCADA systems operate in four layers: 

1. The first one is the on-field layer that comprises physical equipment such as solar PV panels, wind turbines, inverters, BESS controllers, sensors, and more. These are sources of raw data. 
2. The second layer consists of safe and secure communication systems that relay information across the SCADA architecture. 
3. The third component is the core of the system — it’s the supervisory layer comprises data processors, visualizers, alerts, and commands. 
4. The fourth and the final layer consists of integrations and applications like Power Plant Controllers (PPC), energy management systems, asset management set-ups, and forecasting tools. 

Some advanced SCADA systems may include an additional fifth layer for financial management, resource allocation, etc. What’s important is to note that these work in tandem to offer the holistic benefits of control and optimization.

Benefits of SCADA Systems in Renewable Energy Generation

What is it about a SCADA system that makes it such an indispensable control architecture in renewable energy generation? 

SCADA is non-negotiable for stakeholders in the utility sector, Independent Power Producers (IPPs), and even Oil & Gas players diversifying into renewables for many reasons. 

1. Provides Real-Time Visibility Across Assets

One of the key benefits of a SCADA system is its centralized monitoring. The system provides real-time insights into power output, equipment status, grid integrity, environmental data, faults and alarms. For stakeholders managing utility-scale or operationally complex renewable energy plants, this feature significantly streamlines operational procedures and drives measurable efficiency gains.

It also helps avoid sudden-onset expenses that may result from grid malfunction or maintenance and repair requirements. 

Imagine the amplified benefit for those running multiple renewable energy power plants.  

2. Offers Operational Optimization for Grid Code Maintenance 

Modern SCADA systems are capable of much more than monitoring and control. With it, you can use condition-based monitoring and predictive maintenance to help optimize power output and support grid compliance, improving overall efficiencies. SCADA helps with power setpoint optimization, reactive power control, and provides voltage as well as frequency support. 

Besides improving the output, operational optimization helps you maintain grid-code compliance in markets with strict regulatory requirements. It prevents financial losses that you otherwise incur due to non-compliance.  

3. Helps in Downtime Reduction by a Significant Margin

Every minute of downtime costs you money. But downtime can be easily avoided with SCADA’s help. 

How? 

It can detecting anomalies before they turn into an emergency and set off alarms. You can also remotely troubleshoot your problems even if you’re miles away from the powerplant.  

In short, less downtime = higher availability = better returns.

From Monitoring to Intelligence: The Growing Capabilities of Modern SCADA Systems 

SCADA systems have outgrown that industrial usage to become a critical component of today’s renewable energy generation supply chain. The core functionality of centralized monitoring has evolved. Today’s integrated SCADA and PPC solutions rely on technology integrations, such as Artificial Intelligence, Machine Learning, predictive analytics, and more. 

They can be deployed in commercial renewable energy plants to: 

• Pinpoint the underlying reasons for below par performance 
• Improve response times to grid failure and instability
• Standardize and optimize operations across different geographies and of various scales 
• Future-proof the energy production process to reduce maintenance, repairs, and compliance costs. 

While legacy SCADA systems continue to exist, market leaders are uniquely positioning themselves by offering consolidated solutions. 

As renewable markets expanded globally, the industry has moved away from standalone plant-level solutions. Interoperable solutions are the standard now. Open architectures, open sources, centralized but adaptable systems, and comprehensive solutions are gaining momentum.
