Definition: A contractual agreement between a power producer and a buyer, typically a utility or large energy consumer, outlining the terms for the sale of electricity generated by a specific facility over a set period.​

Key Components:

  • Contract Duration: Specifies the length of time the agreement is in effect, often ranging from 10 to 25 years.​
  • Pricing Structure: Details the agreed-upon price per unit of electricity, which can be fixed, escalating, or indexed to market rates.​
  • Delivery Obligations: Defines the quantity of electricity to be supplied and the delivery schedule.​
  • Termination Clauses: Outlines conditions under which the agreement can be terminated by either party.​

Use Cases/Industries:

  • Renewable Energy Projects: Solar and wind farms securing long-term revenue streams.​
  • Commercial & Industrial Sectors: Businesses procuring stable energy supplies at predictable costs.​
  • Utilities: Sourcing additional power to meet customer demand without building new generation facilities.​

Advantages:

  • Financial Certainty: Provides predictable revenue for power producers and stable energy costs for buyers.​
  • Risk Mitigation: Allocates specific risks between parties, such as price fluctuations and operational performance.​
  • Support for Renewable Energy: Facilitates the development of clean energy projects by securing long-term buyers.​

Challenges:

  • Contract Complexity: Negotiating terms can be intricate and time-consuming.​
  • Market Changes: Long-term agreements may not account for future market or regulatory shifts.​
  • Credit Risk: Dependence on the financial stability of the counterparty over the contract term.​

Related Terms:

  • Feed-in Tariff (FiT): Policy mechanism offering fixed payments to renewable energy producers for the electricity they generate.​
  • Net Metering: Allows consumers to offset their electricity costs by generating their own power, feeding excess back to the grid.​
  • Independent Power Producer (IPP): Non-utility entities that generate electricity for sale to utilities or end-users.​

Example: A corporation enters into a 20-year PPA with a solar energy company to purchase electricity at a fixed rate, supporting the company’s sustainability goals and providing cost predictability.
