Voluntary Green Power Procurement
NREL has tracked status and trends in the voluntary green power market since its inception in the 1990s. This work can help corporate purchasers, utilities, and others selling renewable energy products understand available renewable options and move renewable energy forward. Voluntary green power is separate from renewables used to meet state renewable portfolio standards (RPSs).
Status and Trends in the U.S. Voluntary Green Power Market (2017 Data)The latest version of NREL's annual tracking of the voluntary market found that the U.S. voluntary green power market grew to 112 million megawatt-hours sold to 5.5 million customers in 2017. The report covers trends in utility green pricing programs, utility renewable contracts, competitive suppliers, unbundled renewable energy certificates, community choice aggregations, power purchase agreements, and community solar. Some of the report data are available in an Excel format through the NREL Data Catalog.
The Geography of Green Power
This fact sheet explores the geography of green power demand (number of customers) and supply (megawatt-hours of generation) using 2017 data. The fact sheet illustrates how demand for and supply of green power are ubiquitous, with green power customers and generators located in all 50 states and Washington, D.C.
Existing and Potential Corporate Off-Site Renewable Procurement in the Southeast
This project assesses the market for off-site PV in the Southeast, based on projected corporate load, corporate renewable goals for load in the Southeast, solar economics relative to utility rates, presence of a viable PV purchasing method, and other factors. The project team gathered data directly and indirectly from corporations, higher education institutions, and cities and counties with renewable energy targets. The result is a guide for utilities, state policymakers, and corporates trying to meet their corporate RE targets in the Southeast. State summaries are available for Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, and Tennessee.
Community Choice Aggregation: Challenges, Opportunities, and Impacts on Renewable
This report explores the emergence of community choice aggregation, an energy procurement model that puts communities in control of their electricity supply. It features data on community choice aggregation voluntary green power sales and impacts on voluntary green power markets.
Charting the Emergence of Corporate Procurement of Utility-Scale PV
This report examines the benefits, challenges, and outlooks for large-scale off-site solar purchasing in the United States. It features case studies of an aggregate power purchase agreement, a corporation exiting their incumbent utility, a utility offering large scale renewables to corporate customers, and a company with approval to sell energy into wholesale markets.

Policies for Enabling Corporate Sourcing of Renewable Energy Internationally: A 21st
Century Power Partnership Report
This report explores the policy and regulatory enabling environment for corporate sourcing of renewables. The authors find that policy certainty is essential to creating vibrant markets for renewable energy, that policymakers may need to adjust policy mechanisms over time as markets go through different stages of maturity, and that policymakers must also consider the economic decisions that end users make in evaluating projects.

Renewable Electricity Use by the U.S. Information and Communication Technology (ICT)
This analysis examines renewable electricity use by 113 ICT companies in the United States using data from the U.S. Environmental Protection Agency's Green Power Partnership and the Carbon Disclosure Project Worldwide. The 113 ICT companies examined collectively consumed more than 59 million MWh of electricity in 2014, which represents 1.5% of the total U.S. electricity consumption. Of the 59 million MWh, 14% (8.3 million MWh) was sourced from voluntary renewable electricity.
