Campbell County, TN, Public Schools to Generate nearly $1M With Solar

The majority of public schools in Campbell County, Tenn., are going solar in a bid to make $960,000 over 20 years, without raising any additional taxes. That’s under a new partnership with residential and commercial solar installer Efficient Energy of Tennessee (EETN), which is installing solar at 12 of the county’s 21 schools.

The 12 schools in the program are installing 50-kilowatt solar systems, which will sell the power generated to the Tennessee Valley Authority (TVA) through its local power distributor. Already, nine of the installations are complete and the remaining three are currently under construction, according to EETN. Under TVA’s Green Power Providers program, the TVA purchases all the output of the arrays at a premium of 9 cents per kilowatt-hour on top of the retail electricity rate. For years 11 through 20, participants are paid at the applicable retail rate.

“Not only are the solar installations at Campbell County’s elementary, middle and high schools a great STEM teaching tool but, they are generating funds for education without raising taxes,” said EETN President Robbie Thomas. “This financial model, of raising funds for education with solar energy, can be duplicated at school systems across the state of Tennessee.”
The school district, EETN and the Campbell County Finance Department were able to make the installations possible by issuing 15-year bonds. The bonds were used to finance the arrays and their installation. For the first 15 years, the installations are anticipated to produce between $12,000 and $14,400 in annual earnings, after paying all bond interest and principals. After the bonds are repaid, “Each installation will generate approximately $13,000 to $15,000 per year for Campbell County for years 16 through 20 of the power purchase agreement,” EETN said.

In all, the arrays can generate more than $960,000 over the 20 year contracts. The systems are expected to last between 30 and 35 years and could provide additional revenue or cost savings for the schools.

MAJOR FUNDING Through Micro-Investments

The new July/August issue of Solar Today contains an article by TSEAs Technical Director offering a new idea for a solar program within TVA. Micro-investments allow anyone to invest in a project because the cost of a single share is affordable. A recent micro-investment concept was developed by Muhammad Yunus, a Bangladeshi banker who won the Nobel Peace Prize in 2006 for his work in creating economic and social development for the poor. A similar concept, savings bonds, was used in the United States and other countries to finance costs for World War I and World War II. During World War II, half the U.S. population purchased approximately $186 billion in savings bonds. This investment accounted for nearly three-quarters of total federal spending from 1941 to 1945 — all from families whose average wage was $50 per week.

The Tennessee Solar Energy Association (TSEA), an ASES chapter, has as its mission the promotion of the widespread use of solar energy in the state of Tennessee. Unlike most states, Tennessee is served entirely by electric distribution companies who purchase power from the Tennessee Valley Authority (TVA). The TSEA will use the concept of micro-investment to provide opportunities to all ratepayers to invest in solar projects in Tennessee. The success of our endeavors in Tennessee will mean that the concept can easily be duplicated in other states.

Financing solar projects through micro-investments offers many advantages. First, consumers and businesses would neither have to finance nor build their own solar projects on their properties. This eliminates three barriers they often face: (a) unsuitable properties for solar because of trees or rooftop alignments; (b) building permits and grid interconnections; and (c) large financial investments with long payback periods. Second, by opening investment opportunities for all ratepayers, a micro-investment plan should attract customers who otherwise would or could not have considered their own solar projects. Third, micro-financing can be used for large solar projects to benefit entire communities, taking advantage of the lower overall costs of large-scale projects. Finally, micro-investments would provide large sums to utilities and other solar companies who might otherwise not be able to finance a solar project.

Proving the Model at TVA
In the Tennessee Valley, TVA is a closed system in which all 155 distributors buy power from TVA, making it an ideal utility for studying this micro-investment model. Moreover, as a federal power authority, TVA plays an important role in the Tennessee Valley as the regional stewardship agency and supplier of public power. TSEA envisions that TVA would establish a micro-investment program, achieving even greater economies of scale than the individual distributors could achieve.

A 2012 Hart Research survey, funded by the Solar Energy Industries Association, found that 92 percent of voters “believe it is important for the United States to develop and use solar power.” TVA, serving 9 million people in the Tennessee Valley, can play a large role in finding the relationship between how much the public says it wants solar energy and how much the public is willing to invest.

TVA’s aging coal-fired plants are more than 50 years old and are depleting TVA funds to meet increasingly strict air-quality standards. As a result, the TVA has little funding available for solar energy. Although TVA has a renewable energy program known as Green Power Providers, which provides long-term power purchase agreements, the program has not produced a bankable level of funding that has resulted in loss of jobs and statewide solar installers to look elsewhere for work. The small amount of funds allocated for the program were absorbed in the first trimester of this year.

As a federal authority, TVA is in an ideal position to undertake a micro-investment program. Under the TVA charter, the president can direct the U.S. Department of Energy to provide support and resources as requested by the TVA board, which is directed to make studies “in the application of electric power and a better balanced development of the resources of the region” (Tennessee Valley Authority Act of 1933, Section 10). Furthermore, TVA pays no property tax, has a plethora of sites where large solar installations can be located, knows where in its power system to best locate large solar farms to provide the greatest ROI, has the staff to manage the program, can handle the procurement actions and can set aside a percentage of the installations for local installers. Thus TVA can avoid all the soft costs that ordinarily burden solar purchasers. In addition, its purchasing power, backed by the aggregated micro-investments, will produce the lowest cost through competitive bidding.

I suggest to all our members and readers of this column to join ASES and help promote solar energy in their region.

A Second California City Establishes a Solar Mandate

SLevy: The price of electric power in parts of California is as high as 35 cents per kilowatt-hour. A strong motivation for solar whereas Tennessee has a lower price of electricity at the present. The motivation here in Tennessee is improved air quality and a buffer against future costs with other forms of electric power generation.

The town of Sebastopol, in the apple- and grape-growing rolling hills of western Sonoma County, is following suit with a much more aggressive ordinance, suggesting that solar-by-fiat might be more viable as policy. In Sebastopol, a system would also qualify if its output meets three-quarters of the building’s electrical load on an annual basis. The ordinance also includes a provision that allows officials to exempt buildings from the requirement if a site isn’t conducive to solar, but a fee or other energy-saving measures could be required.

Mayor Michael Kyes told the Press-Democrat in nearby Santa Rosa that Sebastopol, with a population of around 7,500, already had some 1.2 megawatts of installed solar capacity. “This ordinance will add to it,” the mayor said. According to the Press-Democrat, there was a citizen objection to the solar requirement registered at the Sebastopol Council meeting; someone said “mandatory sort of implies coercion” (a sentiment it’s hard to argue with). But of course all manner of building requirements are essentially coercive, and Councilman Robert Jacob seemed to capture the sentiment of the town leaders when he said that “this ordinance is not only cost-saving…it’s the responsible thing to do.”

Why is SunPower Doing So Well While Others Fail?

SLevy: Every solar investor wants to maximize its return on investment. In my judgement the reason for Sun Power’s success is they provide a product with the greatest return on investment over the long term. What I mean by long term is tens of years and beyond. Their panels produce the highest output power per area of any other manufacturer. We know that the life of the premiere monocrystalline panels is beyond 40 years. Using 40 years in computing the Levelized Cost of Energy results in more realistic results in cost per kilowatt-hour.

PV energy provider (PVEP) SunPower has revealed that demand exceeded its ability to supply product and services in the first quarter of this year.

The PVEP reported that it had exceeded revenue, gross margin and earnings forecast for the first quarter of 2013, while generating significant free cash flow of US$216 million, including lease financing, which was sold out in the quarter.

SunPower noted that due to several massive PV power plant projects in full swing in the US, strong demand for lease financing rooftop business in the US and ongoing PV module partnership success in Japan that was set to continue throughout the year, it was sold out for the year.
Management noted that its project development business was on course to provide US$3.5 billion in revenue and approximately US$1 billion in gross margin from 2013 through 2016.
Importantly, SunPower said that during the first quarter, the company was awarded 65MW of rooftop projects in France during a recent tender process, which had been supported by majority company owner, Total.

With demand increasing, SunPower said that it increased cell production in the quarter to 208MW, up 36% from the previous quarter. SunPower recognised 172MW of sales, while it shipped 186MW. Total module production capacity remained at 1.2GW. Full capacity was expected to be reached in the second half of the year.

New Music City Center Solar Project

LightWave installs 211 kW Solar on New Music Center

Construction on the $585 million facility began in January 2010 and was completed on April 30, 2013. The Music City Center totals 2.1 million square feet, double the space available in the current convention center. Already more than 100 meetings and 800,000 room nights have been booked.

Project completion will be celebrated on May 19 and 20 at the Music City Center Grand Opening with Nashville Mayor Karl Dean. Celebration includes open house tours, free street party and concert featuring Sheryl Crow, The Time Jumpers with Vince Gill, Fisk Jubilee Singers, and more. Major Dean will give his State of Metro address on Monday, May 20 at 10 a.m.

LightWave Solar recently completed the installation of a 211 kilo-watt (kW) solar system for the Music City Center, and it is the largest solar installation in Nashville.

Installed within the guitar shaped structure on the roof, the system consists of 845 solar panels and four inverters weighing 1,800 pounds each. The system will generate approx. 271,000 kilowatt-hours per year, enough electricity to power the electric vehicle charging stations and lighting for the building. Over 25 years, the clean electricity will offset nearly 5,000 tons of carbon dioxide emissions, the equivalent of taking 920 cars off the road.

Retail Electric Business Predicted to Loose Market Share

The Edison Electric Institute has issued a report predicting that there will be a change in the market share for retail electric business if the present trend towards distributed renewable energy continues at it’s rapidly changing mix of standard electric power production and the increasing percentage of renewable energy sources, particularly solar PV continues to evolve. The report dated January 2013 entitled “Disruptive Challenges: Financial Implications and Strategic Responses to a Changing Retail Electric Business” was authored by Peter Kind of Energy Infrastructure Advocates. The key premise is that the increasing inclusion of solar PV will reduce market share for the electric power industry which will lead to higher risk for investors. The result of a higher risk will be increased cost for borrowing money for the power industry. The report sites two similar industries that were drastically changed by market forces and regulatory changes: the airlines and the telephone (AT&T) industry. The report concludes that near term actions are to “institute a monthly customer service charge”, develop a tariff structure to reflect the cost of service and value provided to DER (solar PV) customers and to “analyze revision of net metering programs in all states so that self-generated DER (solar PV) sales to utilities are treated as supply-side purchases at a market-derived price.”

It is my suggestion that the industry adapt itself to incorporate solar PV in such a way as to improve its retail electric business position. My advice to the industry: constructively adapt renewables into your energy mix: it is not a curse but a blessing.

City to Require Solar in New Construction

Every new housing development must average 1 kilowatt per house. Not here, but in California. California is a light-year ahead of Tennessee and most of the country when it comes to solar acceptance.

The Lancaster, California City Council unanimously approved changes to the city’s zoning code that require housing developers to install solar with every new home they build.
This is the latest piece in what Republican Mayor R. Rex Parris described at the City Council meeting as a plan to make Lancaster “the solar capital of the universe.”
Lancaster’s now official Residential Zones Update specifies, along with a range of green building provisions, that new single family homes meet minimum solar system requirements in the same way that they must meet minimum parking space requirements.
“The purpose of the solar energy system standards,” it reads, “is to encourage investment in solar energy on all parcels in the city, while providing guidelines for the installation of those systems that are consistent with the architectural and building standards of the City.” It is further intended “to provide standards and procedures for builders of new homes to install solar energy systems in an effort to achieve greater usage of alternative energy.”
Residential homes on lots of 7,000 square feet or more must have a solar system of 1.0 kilowatts to 1.5 kilowatts. Rural residential homes of up to 100,000 square feet must have a system of at least 1.5 kilowatts.

U.S. installs more than 3,300 MW of solar PV in 2012

U.S. photovoltaic installations in 2012 increased 76 percent over 2011 numbers to 3,313 MW, with an estimated market value of $11.5 billion, according to GTM Research and the Solar Energy Industries Association (SEIA)’s “U.S. Solar Market Insight 2012 Year In Review.”
Cumulative PV capacity operating at the end of 2012 was 7,221 MW. The U.S. accounted for 11 percent of all global PV installations in 2012. The report predicts the U.S. PV market will grow 30 percent in 2013 with 4.3 GW of new PV installations anticipated during 2013 across all market segments.
Installed prices dropped 27 percent last year and at least 13 percent in each market segment (residential, non-residential and utility).
California led the U.S. in 2011 and 2012 with 1,033 PV installations in 2012, compared to 577 in 2011. Arizona moved up one spot this year to No. 2 with 710 installations in 2012. New Jersey dropped from second in 2011 to third last year with 415 installations in 2012, Nevada jumped from tenth to fourth with 198 installations and North Carolina rounded out the top five with 132 installations.
