Key Considerations When Looking Into Power Purchasing Agreements

Ever wondered how some companies are making the switch to clean energy while slashing utility costs? Well, it''s simple; Power Purchase Agreements. In this blog, we''ll take a look at their origins, discuss their various forms, and reveal the secret workings that fuel their success. Let''s get started! 

What Is a Power Purchase Agreement?

In a solar power purchase agreement (PPA), a host customer agrees to have a solar PV system installed on their property, typically at no upfront cost. They then purchase the system's electric output from a solar service provider for a predetermined period. This type of arrangement promotes the use of renewable energy and allows access to low-cost green electricity, supplying solar energy systems to those who might not otherwise have access.

How Have PPAs Changed Over Time? 

The history of power purchase agreements is linked with the global awakening towards renewable energy. As more countries started acknowledging their environmental benefits, PPAs came into the limelight as a convenient and cost-effective way to embrace solar energy. This trend has only been exacerbated by the advent of third-party financing models, which made it easier to reap the benefits of tax credits associated with solar energy.

What Are the Different Types of Power Purchase Agreements?

Power purchase agreements are not a one-size-fits-all solution; they cater to your specific business model and organizational needs. Generally speaking, there are three main variations, each with its distinct features. 

  • Physical Power Purchase Agreement: A physical power purchase agreement (PPA) is the most traditional form. In this agreement, the host customer agrees to purchase a physical quantity of power over a period, often along with the associated renewable energy credits. As implied by its name, the power is actually transferred from the solar installation to the host customer, who then utilizes it directly.
  • Virtual Power Purchase Agreement: A virtual power purchase agreement (VPPA) is a relatively new variant. Instead of directly purchasing the physical power, a host customer agrees to a financial transaction with the solar service provider in which they buy the renewable energy indirectly. The actual power is not delivered; instead, the host customer purchases and retires renewable energy certificates tied to the power generated by the solar PV system.
  • Synthesis of Renewable Energy Certificate and PPA: Renewable Energy Certificates (RECs) are a way to quantify renewable energy production. They serve as a tradable commodity, representing the green attributes of one Megawatt-hour (MWh) of power generated from a renewable energy resource. The integration of RECs into power purchase agreements, particularly VPPAs, has allowed greater flexibility in promoting solar energy, expanding its reach, and facilitating its growth. This financial tool associated with physical power has been a boon to the solar market, contributing significantly to the current market insight report.

How Do Power Purchase Agreements Work?

Power Purchase Agreements are essentially a legal contract between the generator, usually a company that owns a solar PV system, and the purchaser, whatever entity intends to consume the electricity, often the host customer.

Pricing Structure and Calculations

The pricing structure in a PPA is generally determined by a few key factors, such as:

  • Expected electricity production
  • Investment costs
  • Maintenance costs
  • Agreed-upon profit margins

It''s important to note the pricing model directly influences the power purchaser''s future energy costs.

Duration and Terms of a PPA

The duration of a PPA is usually long-term, often spanning 20 to 25 years. More often than not, the host customer benefits the most from this extended timeframe; enjoying stable, predictable, and often lower energy costs.

When it comes to the terms of a PPA, both parties strive to have conditions that best suit their needs. For instance, a host customer may prefer a flat rate pricing model versus an escalating rate model to ensure utility costs stay consistent.

Legal Considerations for Power Purchase Agreements

Although it provides a plethora of fiscal benefits, implementing a power purchase agreement can be quite complex due to its contractual and legal considerations. The specifics behind each PPA can vary based on individual project needs, however, it generally covers all the following elements: 

  • Price
  • Term
  • Payment process
  • Default provisions
  • Rights and obligations of each party 

It's crucial for both parties to thoroughly understand these aspects before entering into an agreement. If neglected, complexities might arise—especially if the customer and financier are operating in different jurisdictions—as different localities have unique regulations when it comes to renewable energy projects.

How the Regulatory Environment Impacts Power Purchase Agreements 

Renewable Portfolio Standards (RPS) and Feed-In Tariffs (FITs) have significantly influenced the expansion of PPAs in certain regions. In addition to these, other incentives such as federal tax credits and state-specific renewable energy incentives have helped shape the landscape of power purchase agreements. 

What Does the Future Hold for Power Purchase Agreements?

As we usher into a greener era, all indicators point to tremendous growth in the adoption of solar energy systems. Let''s take a look at a few driving factors behind this trend: 

  • New Technologies: The rise of technology is playing a vital role in revolutionizing traditional power purchase agreements. For instance, advanced solar PV systems enhance power production, which are more attractive to the host customer. 
  • Automated Programs: In today''s digital age, seasoned parties are now looking towards artificial intelligence and blockchain technologies to standardize the management of PPAs. 
  • Third Party Financing Models: Among these trends, third-party financing models are gaining the most traction. Put simply, they offer a viable alternative to the end-users who want to capitalize on solar energy but are deterred by the upfront costs. 
  • Decreased Duration: The decrease in solar power purchase agreement's duration is further driving the adoption of this model. Traditionally, agreements would span over 20 to 25 years. However, with the solar PV system cost decreasing, it''s not uncommon for agreements to last ten years or less, bringing more flexibility into the renewable energy market.
