According to a recent time-and-motion study of rooftop solar installations, the biggest opportunity for cost reductions are with integrated racking, and in eliminating the array of little nuts, bolts, wires, clips, pieces and parts that don’t add any functional value to the system, but still need to be assembled on the rooftop.
Based on a tally of 2013 REAP announcements, the total awards for the Southeastern states approaches $5 million in grants, leveraging more than $15 million in private dollars. These investments include solar photovoltaic installations, energy efficiency equipment, geothermal, and biomass projects.
Energy efficiency awards were particularly notable this year, with diverse projects including irrigation, lighting, agricultural curing and drying, and diesel engines being replaced with electric motors.
Here’s the state-by-state breakdown of 2013 REAP grant awards for our region (rounded down to the nearest thousand):
FL > $354,000
GA > $1,400,000
NC > $1,417,000
SC > $584,000
TN > $1,224,000
President Barack Obama has issued a presidential memorandum directing the U.S. federal government to pursue a goal of deriving 20% of its energy from renewable sources by 2020. The document also instructs all federal agencies to take specific steps to better manage building performance, enhance energy efficiency and reduce energy waste.
The missive represents a follow-through on the president’s plan to counter climate change, announced in June. It directs agencies to achieve the renewable energy consumption target through a number of approved actions. The actions, in order of priority, are the following:
Installing agency-funded renewable energy on-site at federal facilities and retain renewable energy certificates;
Contracting for energy that includes the installation of a renewable energy project on-site at a federal facility or off-site and the retention of renewable energy certificates for the term of the contract;
Purchasing electricity and corresponding renewable energy certificates; and
Purchasing renewable energy certificates.
The memorandum sets a number of interim targets for renewable energy usage up to the ultimate 20% by 2020 goal. The first of these is a 10% target for 2015.
Franklin will lease unused land to a Nashville-based company for the future installation of a new solar panel array.
Energy Source Partners is proposing to spend $2.6 million to build a new solar array on a 3-acre sludge field site near Mack Hatcher Parkway. That array is expected to generate 1 megawatt of electricity, which would be sold to the Tennessee Valley Authority.
Over the course of the proposed 20-year contract, the 1 megawatt panels would generate $165,000 for Franklin by the 10th year of the program and about $800,000 from years 10 to 20.
Last year, Franklin leased part of an empty sludge field near its sewer plant off Claude Yates Drive to Nashville-based Energy Source Partners, which paid about $1 million to install 940 solar panels on the land. Those panels, which generate about 200 kilowatts, capture sun rays and convert them to electricity, which is then resold.
KKR & Co. and Google Inc. have struck a pact to invest about $400 million in six solar-power plants being built by Recurrent Energy LLC in California and Arizona. Development of the plants has been under way for years and they are expected to go online and begin producing power in January, the people said.
The plants—five in southern California and one in Arizona—are designed to produce about 106 megawatts of electricity combined, or enough to power about 17,000 U.S. homes, they said. San Francisco-based Recurrent, which will continue as their operator, has struck long-term power supply agreements with three buyers for the electricity they’re expected to churn, the people said.
November 14, 2013. Today at a board meeting in Oxford, Mississippi the Tennessee Valley Authority (TVA) Board of Directors voted to retire units at three of its coal plants. This will affect coal-burning units at the Colbert and Widows Creek plants in Alabama and the Paradise plant in Kentucky.
TVA’s commitment to retire units at three coal plants will protect customers from rising energy bills as coal prices increase, and protect families from the health threats posed by coal pollution. According to the Clean Air Task Force, pollution from the Colbert coal plant in Alabama alone contributed to 940 asthma attacks, 83 heart attacks, and 57 deaths per year.
As the nation’s largest public power provider, TVA was first established to bring innovation to the Valley and address a wide range of environmental, economic and technological issues. As it transitions away from coal, TVA should remain true to its founding principles by bypassing natural gas or any other dirty fossil fuel that will continue to exacerbate environmental and public health issues.
TVA is now mapping out its next Integrated Resource Plan (IRP), the strategy document outlining the utilities energy portfolio for the next 20 years. As TVA works to protect public health and decrease energy costs by moving away from coal, the utility can also commit to speeding the deployment of the most promising and cost-effective renewable technologies, like wind and solar, in its IRP. Wind and solar power are currently experiencing fast growth while simultaneously becoming more cost-competitive with TVA’s other fuel choices.

The Tennessee Valley Authority is gathering public input on a long-range plan for the type and mix of energy sources it needs to provide power to the region.
Finding the right mix of coal, nuclear, natural gas, hydro-electric, renewable energy and efficiency programs is the goal of the 18-month-long planning process, TVA Vice President Joe Hoagland said. “It takes a very long, strategic look at the assets TVA needs to provide low-cost electricity for the people in the Tennessee Valley,” Hoagland said in an interview.
The direction TVA takes will ultimately affect how much residents pay for electricity, and the federal utility is embarking on the planning process at a time when it faces scrutiny from a variety of interest groups.
TVA is spending more than $1 billion to install new pollution controls at its coal-fired power plant in Gallatin. Environmental groups sued TVA for not fully studying alternatives, including retiring the aging facility.
Conservation groups and the solar industry in Tennessee have criticized TVA for not doing enough to support that renewable resource. They say TVA’s small-scale solar program is stifling the industry because it sets a cap on solar power far below demand. Some of the solar installation companies have to look outside the state for work. Our polysilicon manufacturers have laid off their work force. The on-again, off-again opportunities for solar installations are killing the solar businesses in Tennessee.
I attended the first meeting along with 15 other people. Promises of answers to questions have not been received by those that asked questions which the moderator could not answer.
Hoagland said gathering input helps TVA understand what the public and other stakeholders consider important. The “Integrated Resource Plan” looks at different fuel options and tries to anticipate how those might evolve over the next two decades, he said.
TVA completed its last plan in 2011 and typically only does an update every three to five years. But Hoagland said changes in the energy industry require an earlier update.
Natural gas prices have dropped dramatically in recent years in the midst of a nationwide surge in production. At the same time, TVA’s growth in power demand has slowed, Hoagland said.
The 2011 plan anticipated natural gas prices at about $6 per million BTUs, escalating over time, Hoagland said. Now, prices are between $3 and $3.50, he said. The current plan also assumed a 2 percent to 3 percent rate of growth, while TVA now anticipates growth at less than 1 percent.
In addition, TVA hopes to complete the Watts Bar Nuclear Unit 2 plant in 2015 and retire at least 2,700 megawatts of less-efficient coal capacity by 2018.
Anne Davis, managing attorney in Nashville for the Southern Environmental Law Center, said Tuesday that she appreciates that TVA is accelerating the start of the new resource plan. She said she expects the new plan to focus on how TVA will replace its “oldest, dirtiest, and least efficient coal plants with clean and modern resources like solar, wind, hydro optimization, energy efficiency, and demand response.”
“The precipitous drop in cost of renewables and technological improvements in efficiency — coupled with enormous public demand for both of these resources — will demand more attention in this IRP,” Davis said by email.
“We have already been working with TVA on these issues, and we are committed to helping TVA modernize its long-term portfolio in a way that’s protective of ratepayers’ health, environment, and pocketbooks.”
The first public meeting was held on Thursday, October 24th in Knoxville. A second is scheduled for Nov. 6 in Memphis. To encourage more input, TVA is allowing the public to participate through online webinars. The public can access those at www.tva.gov/irp.
TVA hopes to use the webinars and a social media outreach effort to boost public participation, particular with younger residents, Hoagland said.
