A Renewable Energy Certificate (REC) is a market-based instrument that certifies the bearer owns one megawatt-hour (MWh) of electricity generated from a renewable energy resource. This certification allows individuals and companies to claim that they are using renewable energy and supports the development of renewable energy projects.
Types of Renewable Energy Certificates
Compliance RECs
Compliance RECs are used by entities to meet specific regulatory requirements, often set forth by state Renewable Portfolio Standards (RPS). These RECs ensure that entities comply with mandated levels of renewable energy usage.
Voluntary RECs
Voluntary RECs are purchased by organizations and individuals who seek to voluntarily support the production of renewable energy beyond regulatory requirements. These RECs are part of corporate sustainability goals and environmental stewardship practices.
Historical Context of Renewable Energy Certificates
RECs were first developed in response to increasing regulatory policies aimed at promoting renewable energy generation. They emerged as a vital tool to track and encourage the use of renewable energy sources and to incentivize producers by enabling them to sell RECs in addition to the physical electricity generated.
Example of Renewable Energy Certificate Use
A company aiming to go “green” might purchase RECs equivalent to their annual electricity consumption. For instance, if the company consumes 1,000 MWh a year, it would purchase 1,000 RECs to match this consumption with renewable energy. This action does not mean the company directly uses the renewable energy but financially supports renewable energy generation.
Applicability and Benefits of RECs
Environmental Impact
Purchasing RECs supports the development and expansion of renewable energy projects, which helps to reduce greenhouse gas emissions and reliance on fossil fuels.
Corporate Social Responsibility (CSR)
Organizations often include REC purchases as part of their Corporate Social Responsibility (CSR) strategies to demonstrate their commitment to sustainability and to enhance their public image.
Compliance with Regulations
Entities subject to Renewable Portfolio Standards (RPS) can meet their legal obligations by purchasing a sufficient number of RECs.
Comparisons and Related Terms
Power Purchase Agreements (PPAs)
Unlike RECs, Power Purchase Agreements (PPAs) are long-term contracts to buy electricity directly from renewable energy projects. PPAs often come with the legal title to RECs.
Carbon Credits
While both RECs and carbon credits are market-based mechanisms to address environmental impacts, RECs focus on renewable energy generation, whereas carbon credits are centered on reducing overall greenhouse gas emissions.
