Green Power Partnership

Green Power Partnership Program Success Metrics

Since 2001, when the Green Power Partnership started, the program has made considerable progress in addressing market barriers to green power procurement. By offering technical resources and recognizing environmental leadership, the Partnership brings value to its Partners.

At the end of 2018, more than 1,500 Partners were collectively using nearly 55 billion kilowatt-hours (kWh) of green power annually, equivalent to the electricity use of more than 5 million average American homes.

Included below are some additional analyses of the Partnership's metrics.

Relative Scale of the Green Power Partnership

The renewable electricity used by Green Power Partners is just a subset of the overall U.S. renewable electricity market. The graph below shows the relative size of the various renewable electricity markets, such as the entire voluntary green power market and the volume of renewables mandated by RPS policies. In 2017, the volume of green power used by Partners made up almost 41 percent of the voluntary market, about 12 percent of net non-hydro renewable electricity generation (including mandatory purchases), and about 7 percent of all renewable electricity generation.

The graph also shows that all renewable markets have grown from 2016 to 2017.

Number of Green Power Partners by Electricity Loads

The Partnership categorizes Partners as Small, Medium-sized, Large, and Very Large based on a Partner’s annual electricity use.

Small is less than 1 million kWh/year,
Medium ranges from 1–10 million kWh/year,
Large ranges from 10–100 million kWh/year, and
Very Large electricity loads are those greater than 100 million kWh/year.

Small Partners currently represent 53 percent of all Partners, but contribute less than one percent of the program’s total green power use. Very Large Partners, on the other hand, represent only 11 percent of all Partners but constitute 89 percent of green power use.


Annual Green Power Use by Supply Option

The following stacked bar chart highlights the year-over-year changes in supply option mix. The supply option representing the highest proportion of Partners’ green power use is retail RECs. Recently, green power use via financial and physical power purchase agreements (PPAs) have been fast-growing supply options. In 2018, financial power purchase agreements overtook competitive green power products as the second leading supply option by kWh.


Resource Mix by Supply Option

The following pie charts detail the resource mix across each of the predominant green power supply options available to Partner organizations; these include retail renewable energy certificates (RECs), financial power purchase agreements, physical power purchase agreements, competitive green power products, utility green power products, self-supply, utility green tariffs, community choice aggregations (CCA), and shared renewables.


Green Power Usage by Industry

This pie chart breaks out total green power use in kilowatt-hours (kWh) by primary industry sector. Technology and Telecom is the largest user of green power by industry sector in the Green Power Partnership, followed by the Banking & Financial Services, Local Government, and Higher Education sectors.


Use of Various Supply Options by Industry

The following pie charts show the percentage use of various supply options by the Partnership’s top four industry sectors: Tech & Telecom, Banking & Financial Services , Local Government, and Higher Education.

Three out of the four sectors use a high percentage of retail RECs, while the Local Government sector uses 53 percent competitive green power products and only 22 percent RECs. The Higher Education sector uses the highest percentage of physical PPAs, at 24 percent of the sector’s green power use, and the Tech & Telecom industry uses the highest percentage of financial PPAs, at 21 percent. Additionally, the Higher Education and Local Government sectors use a higher percentage of utility green power products compared to Tech & Telecom, while the Financial Services sector hardly uses competitive or utility green power products at all, heavily favoring retail RECs instead.


Why GPP Partners Use Green Power

Current EPA Partners indicate that demonstrating environmental leadership, reducing one's carbon footprint, and supporting renewable energy development are the primary reasons given for why they use green power. Below is a summary of the reasons why our Partners use green power—Partners can check multiple reasons, so the percentages sum to over 100 percent.
