TVA has already reached its 2013 power purchasing limit for 10KW-50KW solar PV systems in its Green Power Providers program. Solar equipment providers say the poorly designed program is costing jobs and not meeting demand for renewable solar energy installations.

TVA SUSPENDS SUPPORT FOR NEW MID-SIZE SOLAR ENERGY SYSTEMS

TVA has announced it has reached a "cap" and will not purchase power from new midsized solar power generation systems that small businesses, farmers, and homeowners want to install in the Tennessee Valley. TVA’s Green Power Providers has a "cap" on the amount of electricity it will buy based on the size of the system. Systems which generate between 10 kilowatts and 50 kilowatts will no longer be able to sell electricity at a favorable price to TVA until, and if, the program is reopened at some unspecified future date. The program may not be reopened.

"The capacity limits for this segment of TVA’s renewable energy programs for all of 2013 were met in less than four months. An April 24th press release from TVA touts the program as being very successful, but TVA met their target for these programs much earlier than expected due to poor planning. TVA approved over 250 small-scale, renewable energy projects for their Green Power Providers and Solar Solutions Initiative programs in 2013, but the demand and potential is significantly higher," said John McFadden, Executive Director of the Tennessee Environmental Council.

The Green Power Providers and Solar Solutions programs are a significant driver for mid-size solar installations in Tennessee. Without these incentives, industry leaders believe the losses to the growing solar industry in Tennessee will cost jobs and money for citizens and businesses. Tennessee, which has climbed to 14th in installed solar capacity in the United States, will fall behind instead of gaining ground.

Lightwave Solar, a Nashville-based solar photovoltaic (PV) system design and installation firm has laid off two employees in 2013 because of softening demand. Gary Wolf of Sundog Solar laments, "If Sundog Solar can't sign up another customer until January of 2014, I'll be out of business before the end of the year and my crew, trained in solar at a Tennessee state school, will be out of jobs. An annual program that lasts four months has at least one obvious problem - size. The caps don't respond to market demand, they force homeowners to compete with commercial interests for solar space, and they undermine job creation and steady employment in one of the nation's fastest growing sectors."

"The ill-conceived construction of TVA’s incentive programs for small and mid-sized solar PV systems has created an unnecessary stop and go situation. Sadly, it is homeowners, small businesses and regional solar installers that are disproportionately impacted," says Michael Levesque, Chief Operations Officer of Sustainable Future, in Knoxville. "Since these programs are the only programs for solar in Tennessee it restricts private citizens and businesses from installing solar power plants. No one is going to build a solar system and provide power to TVA for free, and why should they? People seeking some control over their energy future have no solar alternative."

"Reaching the TVA Green Power Providers program capacity so early in the year has only negative effects on solar businesses and solar clients. This program should be available to TVA customers all year long," adds Ed Zubko, Chief Operations Officer, Green Earth Solar, LLC. "Some of the benefits of the TVA Green Power Providers program to customers are: reduced tax liability, predictable return on investment for the more than 25 year life of the system, saving money on electricity for over 25 years, reduction in the amount of CO2 required to operate a business or residence, support for Tennessee companies with some Tennessee made products available."

Tennessee Chapter Sierra Club Repower America Chair, Mary Mastin, commented, "It makes no sense for TVA to say it has a cap on how much fuel-cost-free electricity it will buy from folks who pay to have a solar system installed at their, home, business or farm. If folks want to dig into their savings to build generation capacity so TVA does not need to borrow money and build power plants and burn coal or uranium we all win. Solar generates no air or water pollution, no coal ash, and no danger from radiation and nuclear waste. TVA has withdrawn support for valley residents and business who want to invest their own money to go solar and this is contrary to TVA's mission and goals"

I'm not sure what this means

I'm not sure what this means fro small home sized installations. It does seem to say that TVA is under the thumb of the energy cartels. Solar makes so much sense in nearly every way, but the problem is that we all have enough solar falling on our heads to run our homes and there's no money in selling it back to us.

Mid sized is NOT home

Mid sized is NOT home systems. Those are up to 10Kw. The allocate a specific Kw of additional they do every year and then cut off at that point. They have reached that point for mid sized systems for this year. There are still KWs available for the small home systems but will also be soon sold out for this year.

I just finished getting my 7kw system installed on the roof of my home and love it!

That's good, thanks for the

That's good, thanks for the info. For some reason I thought home systems were in the 10-12k range. The press release also mentions residential being affected. Maybe they are referring to Al Gore's place. :)

Pardon the typos. Replied on

Pardon the typos. Replied on mobile. There are lots of media folks who love to slam both TVA and any green power projects. It would be great if they increased the annual growth allocations to support demand but this is still a good program. Hope negative media stories do not discourage people willing to invest and participate.

Factchecker's picture

I was going to check that

I was going to check that too. A 10kW system is something like $50k. I'm thinking the minimum size to add to the GP Provider program is 0.5kW. 7kW is very cool, gonzone!

It looks like there's 500kW left for smaller systems, which would be 50 applicants at the full 10kW each.

The caps make no sense. There's also a move sweeping the country among conservative anti-tax governments (redundant, I know) to add new taxes to green initiatives such as electric car ownership. Sad that there aren't enough enough electric cars to add any costs to road infrastructure, and at less than 5,000 lbs. per vehicle it's hard to imagine them doing any real damage. If they become statistically significant in number, start spewing out hydrocarbons, or become hulking 3-ton SUVs we could reconsider the issue.

gonzone's picture

If you are interested my

If you are interested my research showed a 10k system can be installed for about 35k, turnkey. Prices are lower than ever and continue to drop. There are several competent local installers to choose from. They do all the paper work too! An added bonus is the 1k TVA rebate, the 30% federal tax credit, and all income is tax free. Overall, a pretty good investment plus knowing you are doing good for the earth. Remember, do all the conservation things first to reduce consumption, then generate.

Factchecker's picture

Definitely of interest

I'm there with a modest 2kW GP producer. Is that $3.50 per installed watt after incentives? Mine was a little over $4.50 per watt net IIRC (end of 2010).

gonzone's picture

For a large enough system

For a large enough system that goes straight to grid, it's now under 4$ per installed watt and dropping. Depends a lot on the type system you choose.

Factchecker's picture

But is your $3.50 figure

But is your $3.50 figure before or after incentives (30% tax credit)?

Before.

Before. And I did not say 3.50, I said under 4.

...a 10k system can be installed for about 35k, turnkey...

Sorry, this says $3.50/W to me. This would be a really great deal before the tax credit. Other than national data I've not seen what typical all inclusive costs locally have been recently.

Have you seen the new PV panels that integrate a microinverter? A big advantage is how they streamline installation.

gonzone's picture

That is true for a 10kw

That is true for a 10kw system that I considered but smaller systems cost more per watt as do different types of systems. I just didn't want people thinking any system would be as cheap. Sorry if I created a misconception. My 7kw system ended up at nearly 26k if that helps.

Yes, I actually received a bid using the microinverters and it ran just a bit over 4 dollars per watt. I suppose that was due to newer technology still having a bit higher pricing initially. Pretty solid stuff with the advantage of not being as sensitive to shading problems and such if you're willing to pay extra.

It's great there exists so much interest in the subject and I am obviously no expert but might be able to provide some useful information!

PV

another reason TVA can, & will, continue to balk.

(link...)

Germany is approaching 40% solar energy contribution now. This was a gov't, country wide initiative. the utilities in germany don't like it. it cuts into their profits.

all utilities don't want it, period. when the grid starts breaking down, those with solar power will be ahead of those who don't. the grid is now responsible for more losses in the system than power generation

gonzone's picture

TVA wants it. Solar power

TVA wants it.

Solar power shaves the peaks off power demand. That reduces the cost of generating power.

The problem does lie in the distribution grid. Which is why TVA is only purchasing a fixed amount of increase every year.
More solutions to the problems become available every day.

BTW, Grist is a great resource link!

Roof shingles

I have a couple of roofs that face due south at about a 5:12 or 6:12 pich. Pretty much ideal for solar shingles.

Any guess on the time frame when commercially viable shingles will come into play? Are the numbers likely to work for a rental property any time in the forseeable future?

gonzone's picture

From what my research

From what my research indicates, solar shingles are still not efficient enough to really be viable.

Your roof pitch and south facing with no shade does make you a likely candidate. And speaking of shingles, the solar panels protect them so they last a very long time.

No estimated time I know of for the solar shingles. They are available I hear but the efficiency still just isn't there.

My $4 a month

I give $4 a month to Green Power Switch as a token to the program because I believe it in but don't have much money. But I am mad if my money is not going to support green power. Should I cancel my donation and tell them why?

gonzone's picture

Your donation is good

You are guaranteed that much of the power you consume is green power.

I bought several blocks myself for years but am now converting to a producer instead of consumer of green power.

I thank you and the earth thanks you too.

Factchecker's picture

I think anyone who can afford

I think anyone who can afford to invest in the GP producer program and has the other resources (sun and space if it's PV) should do so--it's cool and the right thing to do. But you're not powering your own consumption with renewables unless you buy GPS blocks. TVA is buying this power at a premium price to green their grid. The power becomes theirs to resell and they rightfully and legally get the attributes to call it their green power. Conversely, all the power you consume comes from your utility (after your green meter) and therefore is only as green as the rest of the utility and your neighbors' power.

So even with a huge grid-tied PV system you own, you still have to buy back GPS blocks to be solar powered (or wind or whatever).

No. You're not "donating" as much as you're voting by forcing demand. The program is audited to ensure you're getting green power, and it doesn't even include nuclear or hydro. TVA will buy any amount they're short from outside producers.

(P.S. You're voting because the increased demand shows the utility they need to buy green power or produce it. The latter will make more sense.)

Cost of solar headed for

gonzone's picture

True. And that is with

True. And that is with subsidies for those fossil fuels. Not even mentioning the true cost of burning fossil fuels to the environment.

newboilercost's picture

Getting the subsidy right is key to developing solar

Whilst I am a fan of solar electricity generation in theory I am frustrated that the panel cost are still very high - in the UK its circa $10000 for a 4 kWp installation - $2.50 per W for the average householder.

There is no payback on the investment unless a subsidy is paid by the UK power companies. At the moment this is around 25 cents per kWh. The problem is that if the subsidy is too high then the solar panel suppliers have no incentive to drop their prices or introduce new technology at lower prices.

Dropping or reducing the subsidy is the only way to really keep panel prices falling but too high a subsidy stalls this and too low a subsidy kills the entire new installation market.

A difficult balance to achieve: See (link...) for details on the current UK prices (as of May 2013)

A microinverter system would

A microinverter system would really help with the shading we get, but there were installation barriers that would have driven our costs way up and most if not all microinverters have questionable long term reliability because of the harsh environment and stress put on their components. I'm sure you're up on all that, but the newer technologies seem to be getting around those shortcomings. I'm anxious to find out what kind of replacement hardware will be available when my GP contract expires.
