Gemini Solar Development Company, LLC (Gemini Solar) has received approval from the Austin City Council for a solar system in capital city of Texas. Gemini Solar will construct, own and manage the solar facility. Construction on the project is expected to begin in the first quarter of 2010. The council approved an agreement under which the city’s municipally-owned electric utility, Austin Energy, will purchase all of the electricity produced over a 25year term by a 30 megawatt (MW) project.
The project is expected to be on line by the end of 2010.
The project will be built on city-owned property located about 20 miles from downtown Austin.
The project of photovoltaic solar panels will span around 320 acres, producing energy each year sufficient to power about 5,000 homes. Austin Energy will pay about $10 million per year for the power.
The solar project represents a major step towards fulfilling a Council goal to develop 100 MW of solar capacity for Austin by 2020. The Council also has set a goal that 30 percent of the power delivered to customers by Austin Energy by 2020 will come from renewable resources. The project will result in at least 600 local construction jobs.
The cost of the project was lowered through federal investment tax credits, the value of which was reflected in the bid to Austin Energy. In addition, Austin Energy and Gemini are also assessing and will apply for any potential funding that might be available through the federal stimulus package.
Austin Energy has led 800 utility sponsored green power programs nationwide in green power sales each year since 2002. The utility’s renewables program to date is 99% wind-generated power. In 2004, Austin Energy began a solar rebate program, offering one of the largest solar rebates in the country at $4.50 per watt. Solar installations through the rebate program total about 2.9 MW and include arrays on or adjoining about 693 homes, 56 businesses, 30 city facilities and 21 schools.
The city recently announced a project through which the Austin Energy system will serve as a testing ground for new smart grid technology. The “Pecan Street Project,” as it is called, is being led by the City and Environmental Defense with 11 corporate participants that include the University of Texas and a number of high tech companies. A key facet of the project will be to examine the capability of distributed generation resources, such as solar on homes and buildings, to provide a large share of the power required by a community.
Diversifying our renewable energy portfolio is a key strategy to help insulate our customers from volatility and escalating prices in traditional energy markets, said Austin mayor, Will Wynn. We want Austin to be ahead of the curve as the nation finally takes on the challenge of global warming and makes the transition to a new energy economy.
The solar system will use Suntech polycrystalline silicon solar panels. The panels will be ground-mounted in groups on single-axis trackers. This means they will rotate east to west throughout the day, following the sun, to maximize power production.
“Austin Energy has assumed a leadership role in energy efficiency, green building, renewable resources and smart grid development,” said Roger Duncan, Austin Energy General Manager. “These are the components on which a new business model must invariably be developed for electric utilities due to supply and environmental pressures on energy resources and the enormous potential of smart grid technology.”
