Boulder Solar Grant Program deadline extended to Oct. 31
Aug 31st
More than $80,000 is currently available for the second grant funding cycle of 2012.
The Solar Grant Program is dedicated to providing financial assistance through grants for the installation of solar electric or solar thermal systems on housing for low- to moderate-income residents and on the facilities of nonprofit organizations operating in Boulder. The grants are funded by revenue generated through sales and use taxes from the purchase and installation of solar technologies in Boulder. A portion of the revenue is also used to provide tax rebates for solar installations within the community.
Since the Solar Grant Program began in 2008, it has contributed to the installation of approximately 700 kilowatts of solar power systems, which collectively save grant recipients $90,000 annually in energy costs.* Subject to funding availability, there will be another opportunity to apply for grants in 2013.
The Boulder Climate Action Plan promotes energy efficiency, renewable energy, and transportation options for Boulder residents and businesses. For more information, contact Residential Sustainability Specialist Megan Cuzzolino at 303-441-3452.

Boulder facility goes ‘off the grid’ generating total power from non-fossil fuels for first time
Oct 29th
In this case, Coordinator of Wastewater Treatment Chris Douville explained, the plant was able to draw all of the energy it needed, roughly 1,200 to 1,400 kilowatts at any given moment, from the solar array and from its two co-generation (co-gen) system engines. The co-gen engines capture and burn the gas that is coming off the anaerobic digester process tanks, using that gas to generate additional power instead of releasing it into the atmosphere. The solar system, when at its peak on Thursday, was generating close to 800 kilowatts.
Douville said the success was attributable to a combination of factors, including relatively low wastewater flows, less demand than usual, a clear solar day and cooler temperatures. Data captured at the plant shows the milestone was reached at 11:30 a.m. The plant did not start drawing power from the traditional source again until 2 p.m. Attached is a screen grab that shows the solar photovoltaic production for the day.
“This is a great example of what we can get to,” said David Driskell, executive director of Community Planning and Sustainability. “It shows it is possible to really change our energy mix, and that will have long-term economic and environmental benefits to us as a community.”
While going “off the grid” is impressive, the ultimate goal for the WWTF is for 50 percent or more of the facility’s power to come from alternative sources, over a monthly or annual basis, Douville said. The city hopes to meet this goal through a combination of energy efficiency efforts and maximizing its alternative supplies.
