Understanding Behind-the-Meter PPAs

Behind-the-Meter Power Purchase Agreements (PPAs) are becoming increasingly popular in Australia as businesses look for innovative ways to cut energy costs and enhance sustainability. These agreements present an attractive option for companies aiming to lower their carbon footprint and secure stable, long-term energy prices. But what exactly are Behind-the-Meter PPAs, and how can they benefit your operations? Let’s break it down in simple terms to ensure clarity.

What is a Behind-the-Meter PPA?

A Behind-the-Meter PPA is a contract between a business and a third-party developer who installs, owns, and operates a renewable energy system on the business's property. This system could be anything from solar panels to wind turbines, depending on the site's suitability and energy needs. The business agrees to purchase the power generated by this system at a fixed rate, which is typically lower than the current market rate.

The term "behind-the-meter" refers to the fact that the energy produced is used directly on-site, rather than being fed into the national grid. This setup means that the energy generated is consumed immediately by the business, reducing reliance on external power sources and insulating the business from fluctuations in energy prices. Essentially, it allows businesses to generate their own power and use it as they need it, providing a buffer against the uncertainties of the broader energy market.

Key Advantages of Behind-the-Meter PPAs

Cost Savings

One of the primary advantages of a Behind-the-Meter PPA is the potential for significant cost savings. By locking in a lower energy rate, businesses can achieve greater predictability in their energy expenses. This is crucial for budgeting and financial planning, as it protects the business from the volatile changes in market energy prices. Over the long term, these savings can be substantial, especially for businesses with high energy demands. Furthermore, the fixed-rate nature of the PPA means that businesses can avoid unexpected increases in energy costs, providing a stable financial outlook.

Sustainability Goals

Utilising renewable energy sources through a Behind-the-Meter PPA helps businesses meet their sustainability targets. In today's environmentally conscious market, demonstrating a commitment to sustainability can enhance a company's reputation and appeal to eco-minded consumers and partners. By reducing carbon emissions and reliance on fossil fuels, businesses can play a significant role in global efforts to combat climate change. This move not only enhances your green credentials but also aligns your operations with international sustainability standards and regulations, positioning your business as a responsible and forward-thinking entity.

Energy Independence

Having a dedicated on-site energy source means businesses can reduce their dependence on the grid. This independence is particularly beneficial during peak demand times or grid outages. When the grid is under strain, electricity prices can spike, and reliability can falter. An on-site renewable energy system ensures that your operations can continue without interruption, providing a reliable and consistent energy supply. This is particularly crucial for businesses that require uninterrupted power for their operations, such as manufacturing plants or data centres. By generating your own power, you gain greater control over your energy supply and mitigate the risks associated with external energy dependencies.

How Behind-the-Meter PPAs Work

Understanding the mechanics of Behind-the-Meter PPAs can help you make an informed decision about whether this arrangement is right for your business. Here’s a detailed overview of how these agreements function:


The process begins with an assessment by an energy provider. They will evaluate your site’s energy needs and potential for renewable energy generation. This involves a thorough analysis of your current energy consumption patterns, peak demand times, and the physical characteristics of your site. For example, if considering solar panels, factors like roof space, orientation, and shading will be evaluated to determine the feasibility and potential energy yield. This step ensures that the proposed renewable energy system will meet your specific energy requirements efficiently.


Once the assessment is complete and the feasibility is confirmed, the provider proceeds with the installation of the renewable energy system on your property. This could include solar panels, wind turbines, or other renewable technologies. The installation process is managed entirely by the provider, who handles everything from procuring equipment to ensuring compliance with local regulations. The installation is designed to cause minimal disruption to your operations, and once installed, the system is integrated with your existing energy infrastructure to seamlessly supply power to your site.


With the system in place, you enter into a Power Purchase Agreement (PPA) with the provider. This agreement outlines the terms and conditions, including the fixed rate at which you will purchase the energy generated. The fixed rate is typically set lower than the market rate for grid electricity, ensuring immediate cost savings. The agreement also specifies the duration of the PPA, which can range from 10 to 25 years, providing long-term stability and predictability in your energy costs. The PPA is designed to be flexible, accommodating future changes in your energy needs or operational requirements.


The renewable energy system is maintained and operated by the provider. This means they are responsible for monitoring the system's performance, conducting regular maintenance, and addressing any issues that may arise. Advanced monitoring technologies are often used to ensure optimal performance and to provide real-time data on energy production and usage. This arrangement ensures that the system operates efficiently without placing additional burdens on your staff. The provider’s expertise in managing renewable energy systems means that you benefit from their experience and resources, ensuring high system reliability and performance.


The energy produced by the renewable system is consumed on-site, directly reducing your electricity bills. This immediate consumption means that the energy generated is not subject to transmission losses or additional grid charges, making it more cost-effective. Any excess energy that is not used on-site can often be fed back into the grid, potentially earning you credits or revenue depending on local regulations. This dual benefit of reduced energy costs and potential income from excess energy makes Behind-the-Meter PPAs an attractive option for businesses looking to optimise their energy strategies.

By understanding these detailed aspects of Behind-the-Meter PPAs, businesses can better appreciate the comprehensive benefits and make informed decisions that align with their energy and sustainability goals.
