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 2017, nearly 1,700 Partners were collectively using more than 45.5 billion kilowatt-hours (kWh) of green power annually, equivalent to the electricity use of more than four million average American homes.
Included below are some additional analyses of the Partnership's metrics.

- Resource Mix by Supply Option

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 about 40 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.
*Note that the 2017 Voluntary GP Market bar is dashed because this data-point is a GPP-produced estimate. Official NREL data for 2017 will come out in late fall 2018.
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 Partners represent 57 percent of all Partners, but only contribute less than one percent of the program’s total green power use. Very Large Partners, on the other hand, represent only nine percent of all Partners but constitute 87 percent of green power use.
Very large electricity loads are those greater than 100 million kWh/year,
Large ranges from 10–100 million kWh/year,
Medium ranges from 1–10 million kWh/year, and
Small is less than 1 million kWh/year.
Annual Green Power Use by Supply Option
The following stacked bar chart highlights the year-over-year changes in supply option mix, averaged over all Partner size categories. The supply option most used by Partners is unbundled RECs. Since 2013, direct project engagement through off-site power purchase agreements (PPAs) has been a fast-growing market segment. In 2017, off-site PPAs overtook competitive green power products as the second most used 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 unbundled renewable energy certificates (RECs), utility green power products, competitive green power products, off-site power purchase agreements (PPAs), and on-site generation.
Green Power Usage and Number of Partners 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 Local Government, Higher Education, and Retail sectors.
The numbers inside the sections show the number of Partners in each industry sector. The largest numbers of Partners are in the Higher Education and the Local Government 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, Local Government, Higher Education, and Retail.
Three out of the four sectors use a high percentage of unbundled RECs, while the Local Government sector uses over 55 percent competitive green power products and only 19 percent RECs. The Tech & Telecom industry uses the highest percentage of off-site PPAs, 24 percent, followed by the Higher Education sector, at 18 percent. The Higher Education sector also uses a high percentage of competitive green power products compared to Tech & Telecom, while the Retail sector hardly uses competitive or utility green power products at all, favoring unbundled RECs and on-site generation 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.
