Renewable Energy Credits

What are Renewable Energy Credits (RECs)?
"Renewable Energy Credits", also called "Certificates" (RECs), or "green tags" are created when a qualifying renewable energy facility generates electricity, and represent the broad environmental and economic benefits of green power. RECs are sold separately from commodity power and provide customers a means to green their power supply at a low premium rate. RECs allow customers to purchase green power whether or not they have access to renewable electricity generation and without having to switch electricity suppliers.

When you sign up for Green Up you are purchasing RECs equivalent to 200, 400, or 800 kWh, which is roughly equal to 25%, 50% and 100% of the average home’s electricity use.

How does buying Renewable Energy Credits help increase the amount of energy sources from renewable energy projects?
In most electricity markets, new clean, renewable energy costs more to produce than fossil fuel energy. This difference is primarily due to subsidies that fossil fuel industries receive. However, to remain competitive, renewable energy producers must sell their energy to the grid at conventional market prices. All electricity is the same once it hits the grid, so traditionally consumers have not seen any reason to pay more when fossil fuel energy turns on the lights the same way that wind energy does.

One solution to help open the market to renewable technologies is the sale of Renewable Energy Credits (RECs). A green energy provider (such as the Stateline Wind Farm) is credited with one REC for every 1,000 kilowatt-hours or 1 megawatt-hour of electricity it produces. (For reference, an average residential customer consumes approximately 800 kWh in a month.) An independent agency (such as the Center for Resource Solutions through their program) verifies and certifies the renewable energy product. The green energy is then fed into the electrical grid and the accompanying REC can then be sold to customers separately from the power generated.

By purchasing a REC (through Green Up) to cover your energy consumption, you are paying the difference between market rate and the production rate, allowing more clean power producers to enter the competitive marketplace. Choosing the Green Up program helps avoid fossil fuel fired generation and associated greenhouse gas emissions on the grid. While these may not be benefits to which we can physically claim ownership, the social impact is huge. By purchasing RECs you are helping generate a market for clean, renewable technologies here in the Pacific Northwest. Learn more about renewable energy credits and the
