Since 2000, Tampa Electric has made energy from renewable resources available to residential and commercial customers. Over the years, the company has developed a base of customers that voluntarily purchase renewable energy and make installation and operation of solar photovoltaic systems by Tampa Electric possible.

This is a short annual summary about the various renewable energy programs at Tampa Electric and the value they bring to the communities we serve.

In 2011, Tampa Electric:

• Launched solar rebate programs • Managed six company-owned solar photovoltaic (PV) systems • Installed and donated a PV system to Centennial Middle School in Pasco County• Continued to sell renewable energy blocks for $5 per 200 kilowatt-hours

Solar Rebate Programs In 2010, the Florida Public Service Commission

approved an order that allows investor-owned electric utilities in Florida to provide financial rebates to residential and commercial customers that install solar photovoltaic (PV) or solar water heating systems. In addition, a small budget was made available to help install PV systems at area schools and solar water heaters in newly constructed low-income housing. The rebates – $1.5 million for Tampa Electric customers – are funded through the energy conservation clause. The Solar Rebate pilot was implemented in April, 2011. • For customers that install a PV system, a rebate of

$2,000 per kilowatt installed (up to $20,000 or 10 kilowatts) is available. By the end of 2011, 57 customers with a total of 385 kilowatts of PV installed received $770,000 in rebates. Of the 57 customers, 49 are residential and eight commercial.

• For residential customers that install a solar water heating system, a $1,000 rebate is available. Last year, 46 customers took advantage of the program.

• Through the rebate program, Tampa Electric also reimburses up to $5,000 for the cost to install a limited number of solar water heaters per year in new low-income houses built by a non-profit homebuilder, like Habitat for Humanity.

Renewable Energy Options for Tampa Electric Customers

Solar for Schools ProgramsIn conjunction with the Florida Solar Energy Center’s

SunSmart E-Shelter program, which helps to provide PV systems of 10 kilowatts or larger to Enhanced Hurricane Protection Area emergency shelter schools, Tampa Electric will select one school per year during the pilot program to receive a 10 kilowatt PV system. The donated system will provide electricity for emergency power, help reduce the school’s electricity costs throughout the year, and provide scientific data that can be analyzed by students.

In November 2011, Tampa Electric completed installation of its first donated system at Centennial Middle School in Pasco County.

Company-Owned PV Systems Today, Tampa Electric owns and operates six PV systems

with a total capacity of nearly 82 kilowatts. The systems not only provide solar energy that is fed to Tampa Electric’s grid for voluntary renewable energy program participants, but they also offer our communities an opportunity to learn more about solar energy.

The six systems – with varying sizes and capacities – are sited at:• Lowry Park Zoo• Florida Aquarium

• Manatee Viewing Center • Museum of Science and Industry• Middleton High School in Hillsborough County • Walker Middle School in Hillsborough County

In 2011, these six systems generated about 85 megawatt-hours (85,000 kilowatt-hours) of electricity. That’s enough to power six average-sized homes for an entire year. The environmental impact is equivalent to removing nine automobiles from the road for the year, or planting 17 acres of trees.

Renewable Energy ProgramThe company-owned PV systems are funded by

Tampa Electric customers that voluntarily participate in the renewable energy block program. Residential and commercial customers opt to purchase renewable energy “blocks”. Each block of 200 kilowatt-hours costs $5 per month.

At the close of 2011, Tampa Electric had 2,433 customers participating in the program – subscribing to 3,543 blocks of renewable energy. The company-owned PV systems provide a portion of this energy, and the balance comes from the purchase of renewable energy generated from biomass resources in Florida.

In addition to the monthly block sales, Tampa Electric also offers blocks of renewable energy for specific one-time events, like a Tampa Bay Lightning game at the Tampa Bay Times Forum, the National Football League’s Super Bowl, or a family celebration.

Last year, Tampa Electric customers purchased 8.5 million kilowatt-hours of renewable energy. That’s enough to power 617 homes for one year. The environmental savings are equivalent to removing more than 900 cars from the road for a year or planting 1,700 acres of trees.

Since the program’s inception in 2000, Tampa Electric customers have purchased 48 million kilowatt-hours of renewable energy – enough to power 3,500 homes for a year. These customers have generated an environmental savings equal to removing nearly 5,100 cars from the road for an entire year or planting nearly 10,000 acres of trees.

Centennial Middle School Designated a SunSmart E-Shelter school, Centennial Middle School in Pasco County is the first to receive a PV system donated by Tampa Electric. This 10,000-watt array, funded through the company’s Renewable Energy Systems Initiative (an energy conservation program), will not only provide a power source during emergencies, but will also help the school off-set energy costs throughout the year. Centennial students will have access to the solar power data for analysis and educational lessons.

Lowry Park Zoo Tampa Electric joined with Tampa’s Lowry Park Zoo and the University of South Florida’s Power Center for Utility Explorations on a 15,000-watt solar panel system. The Solar Safari project also includes a touch-screen kiosk and a one-of-a-kind solar tree display that encourages education and conversation about solar energy and its use in remote areas of the world.

Florida Aquarium In Tampa’s Channelside District, the Florida Aquarium’s Explore-A-Shore pavilion hosts a 10,000-watt solar array. In addition to the solar installation, Tampa Electric worked with the Florida Aquarium to install a hands-on display that teaches children about the benefits of solar energy.

Manatee Viewing Center Tampa Electric’s Manatee Viewing Center in Apollo Beach (near Tampa Electric’s Big Bend Power Station) is home to the company’s largest solar panel system, rated at 23,800-watts. A 40-panel system is installed atop the Manatee Viewing Center’s education building and eight pole-mounted arrays are located throughout the parking area.
