TVA Solar Investment in 2013

TVA Solar Investment
• TVA must balance the need for incentives to support new sources of clean, renewable
energy and the impact of these subsidies on consumer power bills. TVA’s mission is to keep
electric rates as low as feasible.
• TVA will invest about $25 million to buy solar energy in FY 2013  part of about $398
million TVA will spend on renewable energy and wind contracts this year.
• TVA’s average cost for all energy generation and delivery is 6.5 cents per kilowatt-hour.
Under its current renewable programs terms, TVA pays:

o Green Power Providers – An average contracted price of 17 cents per kWh over 20
years for solar; 14 cents over 10 years for wind, biomass and small-scale hydro.
o
Renewable Standard Offer – An average market price of 7 cents per kWh for solar;
6 cents per kWh for other renewables over 20 years.

Cap on TVA purchases brings solar eclipse to industry

Since the year 2000, the number of solar power installations in the Tennessee Valley has grown from only three to nearly 1,700.
Buoyed by some of the most generous incentives offered by any utility in the South, TVA gets as much power from the sun as it does from either Norris or Chickamauga dams.
But the boom in small-scale solar generation has turned to a bust for many solar installers this summer. TVA capped its 17-cents-per-kilowatt-hour payment for solar generation to only 10 megawatts this year and the limit quickly was reached before many interested homeowners and businesses were able to take advantage of the offer.
Solar power enthusiasts appealed to TVA directors Thursday to buy more solar through its Green Power Providers program. TVA spends about $25 million a year in above-market payments to buy solar generation to help meet its goal of getting more electricity from renewable sources.
As solar panels become more efficient and the industry matures, TVA is looking to cut that subsidy and move toward more market-rate prices for solar generation.
TVA and Pickwick Electric Cooperative are working with Strata Solar to develop two 20-megawatt solar farms near Selmer, Tenn., which will sell power to TVA at market rates. The new solar installations will be the biggest yet in Tennessee and could provide enough electricity for 4,000 Valley homes.
“I actually think we’ve been in a pretty good spot here,” TVA President Bill Johnson said. “As the price comes down, we can afford to do more solar.”
TVA Chairman Bill Sansom said TVA has to balance the costs of subsidizing small solar units, which tend to increase the average price of TVA power, with consumer desires for more solar and assistance to help nurture the new industry.
TVA opened up another 2.5 megawatts in its Green Power Partners program on Aug. 1, but that capacity was sold at auction in only one minute and most applicants didn’t get a piece of the program. TVA has not yet set the price or capacity for its solar programs for 2014, but officials said the utility should soon announce its plans.
“We are looking at the program and we’re looking at the type of adjustments that we can make to help make it a little more friendly for folks,” said Joe Hoagland, TVA’s senior vice president of policy and oversight.
Large-scale solar farms are adding solar generation at less cost for TVA, Hoagland said. TVA still has nearly 75 percent of the capacity available for such large-scale, market-rate solar generation.
“We want to see more of those because they not only give us more renewable energy, they do it without putting any extra burden on our other ratepayers,” Hoagland said.
Future purchase plans and incentives for renewable power will be shaped, in part, by a new Integrated Resource Plan TVA will launch this fall to study future power options for the next two decades. The updated power plan will be finalized by 2015, Hoagland said.

TVA’s Bill Johnson Updates Repairs to Raccoon Mountain Pumped Store

Background: Raccoon Mountain pumped store is one of the largest in the United States holding the equivalent to 12% of the total energy used in Tennessee in one day. Both nuclear and solar PV need energy storage to maximize the return on investment. Pumped storage of water is the most cost effective massive energy storage method known today. Construction at Raccoon Mountain began in 1970 and was completed in 1978. The reservoir constructed at the top of the mountain has 528 acres of water surface. The dam at Raccoon Mountain’s upper reservoir is 230 feet high and 8,500 feet long. It’s the largest rockfill dam ever built by TVA. Raccoon Mountain Pumped-Storage Station is a hydroelectric facility. It has four generating units with a net dependable capacity of 1,652 megawatts. Net dependable capacity is the amount of power a plant can produce on an average day, minus the electricity used by the plant itself. Several units at the 600 MW Raccoon Mountain pump storage facility were taken offline in 2010 due to rotor cracks.

Update on the status of the repair work at that plant by Bill Johnson. In an interview with Power Engineering Mr. Johnson, President of TVA, said that all four of those units were taken out of service after the discovery of cracks in the rotors. “There’s a similar plant in Europe where the cracks were first discovered, and when we inspected here we found the same thing. We are having new rotors manufactured in Europe. I would expect the first unit to be back online around July of this year, and the other three probably in the next ten to twelve months. We’re actively working on that. While the plant was down, we’ve done a lot of other things: replaced transformers, did some other things, but I would hope that we’ll see the first unit coming back in the July timeframe.”

Legislation Expands U.S. Hydropower Production Which Will Benefit Pumped Storage and Solar Dispatchability

Legislation designed to expand hydropower production in the United States by improving and streamlining the licensing process for small hydropower projects is now law. “President Obama’s signature on hydropower legislation is terrific news for expanding renewable energy and creating jobs across the country,” said Voith Hydro President and CEO Kevin Frank.
The Hydropower Regulatory Efficiency Act will require FERC to examine a 2-year licensing process for non-powered dams and closed loop pump storage. TVA should give top priority to increasing their pumped storage using no longer active mine, coal washing stations and converting them to closed pumped storage facilities. First, these are environmentally damaged facilities that need attention. Second, by adding a surface reservoir to receive the water from the elevated tailing ponds, TVA could increase its pumped storage first with closed pumped storage, then modifying existing dams to create a lower pond below the dam receiving stream. According to one source at TVA the issue with increasing pumped storage is the objection on environmental grounds. The answer is to select those sites that would have the lowest environmental impact using groups like the Sierra Club to help with the selection and the environmental impact study.

We need to increase pumped storage for both renewables and for nuclear plants. TVA has 47 dams listed on their website. There is a good chance that some of these dams would lend themselves to pumped storage. That is where TVA should invest.

FERC Chair Jon Wellinghoff: Solar ‘Is Going to Overtake Everything’

If anybody doubts that federal energy regulators are aware of the rapidly changing electricity landscape, they should talk to Jon Wellinghoff, chairman of the Federal Energy Regulatory Commission (FERC).

“Solar is growing so fast it is going to overtake everything,” Wellinghoff told GTM last week in a sideline conversation at the National Clean Energy Summit in Las Vegas.

If a single drop of water on the pitcher’s mound at Dodger Stadium is doubled every minute, Wellinghoff said, a person chained to the highest seat would be in danger of drowning in an hour.

“That’s what is happening in solar. It could double every two years,” he said.

Geothermal, wind, and other resources will supplement solar, Wellinghoff said. “But at its present growth rate, solar will overtake wind in about ten years. It is going to be the dominant player. Everybody’s roof is out there.” Advanced storage technologies also promise lower costs, he said. “Once it is more cost-effective to build solar with storage than to build a combustion turbine or wind for power at night, that is ‘game over.’ At that point, it will be all about consumer-driven markets.”

If FERC does not ensure the grid is ready to integrate the growing marketplace demand for distributed solar and other distributed resources, Wellinghoff said, “We are going to have problems with grid reliability and overall grid costs.”

Transmission infrastructure will be able to keep up with solar growth. The big changes will be at the distribution level where FERC has less influence, he explained. But the commission has been examining the costs and benefits of distributed generation (DG) in wholesale markets.

“Rate structures need to be formulated in ways that fully recognize the costs and benefits of distributed resources,” Wellinghoff said. “In many utility retail rates, a disproportionate amount of the fixed costs are recovered through a variable rate. That is problematic when a lot of people go to distributed generation.”

The net metering controversy this has caused at utilities like Xcel and Arizona Public Service, he said, can only be resolved by “the fully allocated, fully analyzed cost and benefit study of distributed resources.”

Home Owners Associations and Your Solar Rights

This blog is the result of many calls to TSEA regarding homeowners rights when their home owners associations prevent homes in their association from installing solar panels. The original article is thanks to the American Solar Energy Society (ASES) and their solar citizen newsletter. Join TSEA and ASES to create a strong ally in promoting solar in our state and in our country.

By Steve Wright

The benefits of residential solar panel arrays are becoming clearer with each passing year. Rooftop solar panels reduce energy expenditures, carbon emissions and infrastructure-related inefficiencies. There’s also mounting evidence that solar increases the value of the home. Unfortunately, homeowner associations across the country continue to ignore the overwhelmingly positive body of evidence and impose onerous restrictions on residential solar panel installations. Read on to learn how to fight back.

Rights of the HOA
Well-established legal precedents support efforts by HOAs to impose “reasonable restrictions” on their members’ attempts to install solar panels. Generally speaking, courts have been reticent to overturn specific HOA bylaws unless they are found to be arbitrary, unconstitutional or blatantly illegal.

Because an outright ban might look arbitrary (or illegal in many states), HOAs often make rules that restrict the visibility and size of solar panel arrays. Ostensibly designed to promote health and “peace of mind” by reducing glare and rendering “eyesores” less visible, these restrictions often compel homeowners to move their panels to shady, fenced-in yards or to first-floor roofs that can’t be seen from the road.

Unfortunately, HOAs can also use certain legal caveats to deny solar panel installation outright. These often take the form of restrictive covenants designed to preserve or increase property values. They may purport to preserve a community’s “brand” by standardizing the appearance of its homes. Unlike restrictive covenants that come with “sunset clauses” or “express termination” windows, bylaws that restrict solar panel use tend to be permanent and must be invalidated by legal challenges or law changes.

Solar Access Laws
With this in mind, several states have enacted common-sense legal protections for homeowners who want to go solar. While these generally don’t interfere with the “reasonable restrictions” guideline, they prevent persnickety HOAs from making punitive demands on well-meaning members.

California’s Solar Rights Act serves as the model for most of these state laws. Although it was originally intended to prevent HOAs from imposing arbitrary restrictions or outright bans on solar panel arrays, it has since been expanded to cover municipal and regional government bodies. The law has also been amended to ensure that homeowners retain access to state-sponsored solar energy grants and to protect inhabitants of multi-unit dwellings like high-rise apartments and condominiums.

Florida’s own Solar Rights Law offers similar protections. Without interfering with the commonly accepted “reasonable restrictions” allowance, the law prohibits HOAs from banning solar panel arrays and specifically overrides any HOA bylaws that curtail the installation of rooftop solar panels. In other words, Florida homeowners can use most or all of their roofs’ square footage to install arrays.
Even wintry Massachusetts has gotten in on the action. The state’s Solar Access Law nullifies existing and future HOA prohibitions and expressly permits solar easements on residential land. Even better, it prohibits HOAs from restricting the trimming and clearing of vegetation that obscures solar panels on members’ properties.

Remedies for Homeowners
Most homeowners start by attempting to persuade their HOA to refrain from unreasonable restrictions on solar panel installation. This requires an age-old persuasion tactic: the power of credibility. Homeowners often point to credible sources that support the efficacy of solar power. They might cite the U.S. Energy Department’s estimate that a single 10,000 square-mile patch of the Nevada desert receives enough sunlight to satisfy the entire country’s energy needs, or multiple studies that have found a positive correlation between residential solar panel arrays and home values.

Such persuasive efforts must focus on the positive aspects of solar power and cite concrete evidence from non-controversial sources. You could argue that solar panels would reduce homeowner electricity bills and the frequency of peak-period blackouts. Use a politically-neutral source for your facts — the U.S. Department of Energy has a website rich with good data. It’s hard to argue with concrete evidence.

If these efforts prove insufficient, homeowners generally attempt to negotiate a compromise agreement. Since aesthetic concerns often drive these restrictive covenants, successful agreements may require homeowners to keep front-facing portions of their roofs free of solar panels. As a compromise, HOAs might allow solar panel users to trim trees that shade these arrays. Magnanimous homeowners might even volunteer to divert a portion of their panels’ production to commonly held equipment like public-area sprinkler systems or streetlights.

In the worst case, a homeowner may be forced to take legal action against a stubborn HOA. Pro-solar organizations advise homeowners who pursue this course of action to focus on HOA-initiated actions that a court might find to be arbitrary, punitive or “unreasonable.” Ultimately, litigants must be prepared to cite facts that refute common arguments about negative home-value and aesthetic impacts. Those who wish to pursue legislative remedies often use stronger solar-rights laws, like those in Massachusetts and Florida, as templates.

Conclusion
Despite widespread legal protections for homeowners, many HOAs go to great lengths to restrict members’ rights to install solar panel arrays on private property. In a world beset by rising fossil-fuel energy costs, weakening electric infrastructure and a deteriorating natural environment, tension between an HOA and its members is counterproductive. Fortunately, commonsense legislation and a growing body of pro-solar legal precedents have made it easier for homeowners to fight back against overzealous HOAs.

TVA proposed Solar Aggregated Value and Education (SAVE) Initiative

TVA will install at least 500 kWs of solar PV at TVA facilities, TVA directly served customer locations, or another government-owned facility (including all local public power companies served by TVA), and shall maintain the PV installations for a minimum of twenty years following approval of project plan. The objective of SAVE is for TVA to partner with the regional community to raise solar energy awareness and education, reduce solar energy costs, and to test the market for upfront Renewable Energy Credit (REC) purchases. The SAVE initiative is based on a community solar business model which brings together individual donors, organizations, and investors to leverage community engagement and maximize stakeholder value.

Author’s comment:
1. it does not address distributor’s concerns; 2. It does not address soft costs; 3. It does not avoid borrowing of money; 4. It may not locate the solar where it can be best incorporated; 5. It is too small to make an impact on increasing consumer demand; 6. Who manages the overall program(s)? 7. Continue the concept of asking for donations?

Tea Party Joins with the Sierra Club to Promote Solar in Georgia

As Debbie Dooley co-founder of the Atlanta Tea Party explains, “I’m a grandmother, and I want to be able to look my grandson in the eyes and tell him I’m looking out for his future. Conservation is conservative, and protecting our children and our natural resources is a conservative value.” Those who believe in the free market need to reexamine the way our country produces energy. Giant utility monopolies deserve at least some competition, and consumers should have a choice. It’s just that simple, and it’s consistent with the free-market principles that have been a core value of the Tea Party since we began in 2009.

“In Georgia, we have one company controlling all of the electricity production, which means consumers have no say in what kind of power they must buy. A solar company could not start up and offer clean power to customers because of restrictions in state law. Our Constitution does not say that government should pick winners and losers, but that is what government is doing when it protects the interests of older technologies over clean energy that’s now available at competitive prices. I say, let the market decide” says Debbie.

She goes on to explain, “Georgians are currently and unjustly denied this opportunity, and will continue to be unless a law is passed to change the system. That is why the Atlanta Tea Party supported Senate Bill 401 in the past legislative session. Georgia Power opposed it and it never made it out of committee. We will try again when the Georgia legislature reconvenes in January 2014. All states should allow their citizens the opportunity to generate and sell their own solar power.”

So I ask our elected state and federal officeholders, “Why hesitate in voting for extending the Master Limited Partnership to renewables?” Level the energy playing field. Here in Tennessee, our citizens have the same demands as our neighbors in Georgia. TVA board serves the people in the valley, why not listen to their demands for cleaner energy?

Postscript: Americans for Prosperity, which like the Tea Party have been nurtured and sponsored by the Koch brothers oil billionaires, is dismissing the Georgia faction as an aberration, or even more damming, as a “green Tea Party.” It has sought to turn the issue of rights on its head by arguing that rooftop solar will “infringe upon the territorial rights to the distribution grids” of the network operators.

TSEA August Newsletter Editorial

TSEA Editorial

Disputes over the use of small-scale solar power are flaring across the nation. At issue in an Iowa lawsuit is whether solar-system marketers can sell electricity in territories where local utilities have exclusive rights to customers.

In TVA territory distributors are forbidden from generating electricity and that extends down to small installations on residential homes. The overall concept of an individual providing some of its own power and selling the rest to the utility company is called net metering.

Net metering or net energy metering (NEM) allows electricity customers who wish to supply their own electricity from on-site generation to pay only for the net energy they obtain from the utility. NEM is primarily used for solar photovoltaic (PV) systems at homes and businesses (other distributed generation (DG) customers may have access as well). Since the output of a PV system may not perfectly match the on-site demand for electricity, a home or business with a PV system will export excess power to the electric grid at some times and import power from the grid at other times. The utilities bill customers only for the net electricity used during each billing period. Alternately, if a customer has produced more electricity than they have consumed, the credit for that net excess generation will be treated according to the NEM policy of the state or utility.

Benefits of distributed solar include:

• PV systems generate the most electricity during the middle of the day when demand is the highest.
• Net metered PV systems reduce the need to expand transmission grid capacity
• Net metering allows for the development of a solar energy market and the jobs that come with it

Currently 44 states plus D.C. have implemented net metering policies. The following map shows the six states that forbid net metering.


Utilities “are proponents of renewable energy,” said Barry Shear, president of Iowa’s Eagle Point Solar LLC, but only “if they own the energy assets and the electrons flow through their grid and they can bill you.”
“The electric utility industry’s preservation of revenues and investor capital will be determined by its success in aligning with the following five consumer mega-trends reshaping the U.S. economy” says Bill Roth President of NCCT, a nationally recognized business coach, economist, ranked as a top-five writer on sustainability and business best practices. To paraphrase his proposed trends as:
1. Consumers are in active pursuit of lower bills,
2. The electric utility industry’s revenues are at risk with a generation that views the industry as missing in action,
3. Today moms manage the household budget. They expect the companies they do business with, including their utility, to provide products and services that align with their values,
4. Electric utilities need to mimic CEOs of major corporations who are adopting sustainability to reduce their operating costs, increase customer alignment and mitigate risks, and
5. Consumer acceptance of cost reducing disruptive technologies that challenge existing utility economic models.

The issue being brought up in this Iowa dispute is the question as to who supplies electric power to residential customers. The dispute can be resolved with changing the economic model of how solar can be integrated into the existing business models of TVA and independently owned utilities. Nobody has to lose. The existing model in our state can be preserved allowing TVA to generate all the electricity selling the power through their distributors who connect the electricity to the residential commercial customers.
The issue now is not who owns the power sources, but how we raise the funds for solar farms and distributed solar needs. The answer maybe to apply the economic model of micro-investments.
The model published in the July/August issue of Solar Today, addresses the existing barriers through the following channels.
• The income will be generated by residential customers who are interested in improving their environment as well as income generation.
• TVA will manage all future solar installations in cooperation with their distributors.
• Income from the sale of solar power will be channeled from TVA and it’s distributors to the residential investor.
• TVA and its distributors will be responsible for the operation and maintenance of all solar generation where the cost for the O&M will come from the profits of solar sales.
• Home owners and businesses that sign up for the program will agree to compensate the distributors for the cost of maintaining and upgrading the distribution system.
• For distributed generation TVA will compensate the owner of the property for renting their roof.

The essence of the model is discussed in the Solar Today article which can be retrieved at the American Solar Energy Society (ASES) website
