What is a Power Purchase Agreement (PPA)?

A Power Purchase Agreement (PPA) full form is a contract between a power producer and a buyer. This agreement is crucial for defining the terms and conditions under which electricity will be supplied from the producer to the buyer. Typically, these agreements span over a long period, often between 10 to 25 years, providing a stable and predictable energy supply. For businesses, PPAs offer numerous benefits, such as locking in long-term energy prices, which helps in budgeting and financial planning. Additionally, they play a significant role in supporting renewable energy projects, contributing to sustainability goals and corporate social responsibility.

Why are PPAs Important for Businesses?

Businesses require a reliable and affordable energy supply to operate efficiently. A Power Purchase Agreement (PPA) ensures a steady and predictable electricity source, which is especially vital in regions like Australia, where energy prices can be highly volatile. Here’s a closer look at why PPAs are essential for businesses:

Lock in Energy Prices

One of the primary advantages of a PPA is the ability to secure long-term energy pricing. This means businesses can lock in a fixed or predictable energy cost, protecting them from market fluctuations and unexpected price hikes. This stability is invaluable for financial planning and budgeting, allowing companies to allocate resources more effectively.

Support Sustainability

Investing in renewable energy projects through PPAs helps businesses meet their sustainability goals. By purchasing electricity from renewable sources such as wind or solar, companies can reduce their carbon footprint and contribute to environmental conservation. This not only aligns with corporate social responsibility initiatives but also enhances the company’s reputation among environmentally conscious consumers and stakeholders.

Gain Financial Benefits

PPAs can provide access to various financial incentives, including tax credits and grants available for renewable energy investments. These incentives can significantly reduce the overall cost of energy, making renewable options more competitive with traditional energy sources. Additionally, PPAs can offer businesses a hedge against future regulatory changes related to carbon emissions and energy use.

Types of Power Purchase Agreements

Understanding the different types of PPAs is crucial for businesses to choose the agreement that best suits their needs. Here are the main types of PPAs:

Physical PPA

A physical PPA involves the direct delivery of electricity from the producer to the buyer through the electrical grid. This type of agreement is ideal for businesses that want a tangible connection to their energy source. In a physical PPA, the energy produced by, for example, a wind farm or solar plant, is physically delivered to the buyer’s location.


  • Direct Connection: Businesses receive the electricity directly from the producer, ensuring a clear and direct energy supply.
  • Energy Security: Physical PPAs provide a guaranteed energy source, reducing dependency on traditional utility providers.
  • Transparency: Clear visibility of energy sources and consumption.


  • Infrastructure Requirements: May require significant infrastructure for the direct delivery of electricity.
  • Geographic Limitations: Suitable only if the energy producer is within a reasonable distance from the buyer.

Virtual PPA

A virtual PPA, also known as a financial PPA, does not involve the physical delivery of electricity. Instead, the producer sells the generated electricity to the grid, and the buyer receives financial credits or offsets. This arrangement is suitable for businesses that want to support renewable energy projects but cannot directly receive the electricity.


  • Flexibility: Businesses can support renewable energy projects regardless of their location.
  • Financial Benefits: Receive financial credits or offsets, which can be beneficial for companies with multiple locations.
  • Simplicity: No need for physical infrastructure to deliver electricity.


  • Indirect Connection: Businesses do not receive the actual electricity generated by the producer.
  • Complex Financial Arrangements: Understanding and managing the financial aspects can be complex.

Sleeved PPA

A sleeved PPA involves a third party, usually an energy retailer, who manages the physical delivery of electricity from the producer to the buyer. This arrangement simplifies the process for businesses, as the retailer handles the logistics and delivery.


  • Simplified Process: The energy retailer manages the complexities of energy delivery.
  • Energy Security: Ensures a reliable and steady energy supply.
  • Flexibility: Combines the benefits of physical and virtual PPAs.


  • Additional Costs: May incur additional costs due to the involvement of a third party.
  • Complexity: Managing agreements with both the energy producer and the retailer can be complex.

Key Components of a PPA

Contract Term

The contract term refers to the duration of the agreement, typically ranging from 10 to 25 years. This period is crucial as it impacts the long-term energy strategy of the business. A longer contract term can provide stability and predictability in energy costs, allowing businesses to plan their finances more effectively. It also ensures a prolonged commitment to renewable energy sources, which can enhance a company's sustainability credentials. However, it's important for businesses to carefully consider their future energy needs and market conditions when agreeing to a long-term contract.

Pricing Structure

The pricing structure outlines how the electricity price is determined throughout the duration of the PPA. There are several pricing models to consider:

Fixed Pricing: The electricity price remains constant over the term of the agreement. This model offers predictability and stability, making it easier for businesses to budget for energy costs.

Escalating Pricing: The price of electricity increases at a predetermined rate over time. This model can start with lower initial costs, which can be beneficial for businesses with tight current budgets but expecting higher revenues in the future.

Market-Based Pricing: The price is linked to the market rates of electricity. This model can offer cost savings when market prices are low, but it also carries the risk of price increases, making budgeting more challenging.

A clear and well-defined pricing structure helps businesses manage their energy budgets and ensures there are no unexpected costs.


Volume specifies the amount of electricity the producer will supply and the buyer will purchase over the term of the PPA. This component is critical as it defines the energy commitment of both parties. Accurate forecasting of energy needs is essential to avoid overcommitting or underutilising the contracted energy, which could result in financial penalties or inefficiencies. Businesses need to consider their current and future energy consumption patterns, potential growth, and any energy-saving initiatives when determining the volume of energy to contract.

Delivery Point

The delivery point is the specified location where the electricity is delivered or credited. This could be the business’s premises or a designated point on the electrical grid. The clarity of the delivery point ensures that both parties understand where the energy is being delivered, reducing the risk of disputes and logistical issues. It also affects the logistics and potential costs of energy distribution. For businesses with multiple locations, it's important to ensure the delivery point aligns with their operational needs.

Renewal and Termination

The renewal and termination section details the conditions under which the contract can be renewed or terminated. This provides flexibility and security for both parties. Key considerations include:

Renewal Terms: Conditions under which the contract can be extended beyond its initial term, including any changes to pricing or volume.

Termination Clauses: Specific conditions that allow either party to terminate the agreement before the end of the term. This could include breaches of contract, changes in market conditions, or regulatory changes.

Having clear renewal and termination terms protects both the buyer and the producer from unforeseen circumstances and ensures that there is a clear process for ending or extending the agreement.
