The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

City of Houston - Green Power Purchasing   

Last DSIRE Review: 12/17/2012
Program Overview:
State: Texas
Incentive Type: Green Power Purchasing
Eligible Renewable/Other Technologies: Wind
Applicable Sectors: Local Government
Renewables % or Amount:35%
Web Site:

In 2007, the City of Houston negotiated a 5-year contract with Reliant Energy for up to 80 MW or 700 million kilowatt-hours (kWh) annually of renewable energy credits (RECs). These RECs will be generated almost exclusively from wind power. The purchase began in July 2008 at 40 MW, equivalent to roughly 350 million kWh annually or 25% of the annual electricity consumption of the city's municipal facilities. Additional 10 MW increments of renewable energy are authorized to be stepped in over time up to the 80 MW specified in the contract. As of January 2012, the purchase had been increased to 50 MW, equivalent to roughly 438 million kWh annually approximately 35% of annual electricity consumption in city facilities.

This diversification of Houston's energy portfolio is expected to help insulate the city from price shocks such as those that occurred in the aftermath of Hurricanes Katrina and Rita. Between January 2009 and December 2012, Houston has captured the second spot on the EPA's Green Power Partner list of green energy purchases by local governments.
