Frequently Asked Questions

Renewable energy for Windsource is provided from Xcel Energy’s wind resources in Colorado, which total over 2,200 megawatts. The electricity is added to the Xcel Energy system for use across our service area in Colorado.

At any given time, Xcel Energy may be purchasing more or less renewable energy than is being sold through Windsource. We balance the sales and generation of the program on an annual basis using the environmental and consumer protection standards established by the non-profit Center for Resource Solutions in its Green-e Energy™ Program. For more info on Green-e Energy, visit www.green-e.org. Green-e certifies that Xcel Energy generated as much renewable energy as you purchased, above and beyond our other regulatory mandates.

The renewable energy facilities that supply Windsource are connected to the electric system or grid. Windsource and all other Xcel Energy electric customers draw electricity from the grid to meet their electricity needs, 24 hours a day.

Electricity generated by renewable facilities, such as wind turbines, as well as conventional sources travel together to supply homes and businesses. A simple analogy is to think of the electric grid or system as a giant lake that all customers draw from as they use electricity. Many different generation sources add to filling the “lake”; electricity from wind turbines, coal plants, hydroelectric plants, and natural gas fueled plants. As demand for Windsource rises, over time more wind turbines will be added to help supply the “lake” with more clean, wind-generated electricity.

Windsource won’t affect the reliability of your electric service. While wind energy generation is dependent upon the availability of the wind, your electric service will continue to draw from the electric grid, which includes a variety of energy sources.

Yes. The Xcel Energy electricity mix in Colorado uses a variety of resources. For comparison, the 2016 average mix of resources supplying Public Service Company of Colorado included: coal (46%), natural gas (25%), wind (23%), hydro (4%), solar (2%). The energy that supplies Windsource is purchased entirely from wind farms in Colorado and will go above and beyond government mandates.

Renewable Energy Credits (RECs) are the currency used to measure the renewable energy produced and used to meet renewable energy goals. With Windsource, the RECs are retired on your behalf, which allows you to say that they are offsetting or using renewable energy.

You choose how much you want. Start with one block, which is the equivalent of 100 kWh of electricity, or about enough electricity to power the lights in a typical home for a month*. You can also choose to get 100% of your energy from Windsource.

*Lighting Calculation: Based on home with 42 light sockets, using a mix of CFLs, LEDs and incandescent bulbs.

The average home uses around 700 kWh per month. With Windsource, that would equate to an additional $10.50 per month.

Residential customers join Windsource to support the increase in renewable energy generation and to be a part of a growing community of environmentally-conscious consumers.

The increase in wind energy generation has a number of tangible environmental benefits.  Wind energy takes advantage of an abundant natural resource with no greenhouse gas emissions and little waste. Wind is a domestic energy source that helps preserve our natural resources for the future.

Wind energy has real economic benefits. Installing and maintaining wind turbines creates jobs. Ongoing lease payments are made to land owners who can still use the land for other purposes uses, such as farming. And wind turbines create additional tax income for counties.

Windsource subscriptions are available in 100 kilowatt-hour (kWh) blocks for a small additional premium of $1.50 per block ($0.0150 per kWh).

Windsource is billed on a monthly basis. The extra renewable energy charges appear as a separate line item labeled “Windsource." Other taxes, fees and adjustments still apply. 

Absolutely! As long as you are an electric customer of Xcel Energy in Colorado, you can participate in Windsource and contribute to a cleaner environment while taking advantage of our abundant natural resources.
