The distribution grids that deliver TVA electricity consist of a network of wires that carry the power around (to consumers). Distributors within the TVA system must agree to carry the power of all comers, at non-discriminatory rates too. And it can charge a fee sufficient to cover the cost of providing a reliable, responsive grid.
“Then you’ve two other parts of the system: those who own the power stations that feed electricity into the grid and those who run marketing organisations to bill for what consumers pull from the grid. And within such a system it’s simple enough to make sure that everyone who has a grid connection is charged for the use (even if that use is only insurance against cloudy days) of the grid in the appropriate manner and amount. Without having to worry about how much electricity they’re actually using.
This really is a real problem with solar power: and that really is the solution. Unbundle the utilities into a pure grid charging all for the use of it and keep that very separate from who is generating power by what means”, suggests Tim Worstall Forbes’ contributing author

CHARLESTON, Tenn. — Construction of Wacker’s $2 billion polysilicon production plant now has about 1,000 builders on site daily as the factory’s planned startup is a little more than a year away. Unlike the Hemlock plant, this plant will open as scheduled.
“We’re pushing the project forward,” he said about the factory’s current construction schedule. “It’s pretty exciting to us.”
Wacker has hired 180 employees of the 650 it will need when production starts next year, Bachhuber said. “The backbone of the future is on board,” he said about those employees who are doing about 30 different tasks for the company. Some of the rest of the hiring is slated for later this year, though most will be done in 2015, Bachhuber said. “Many of the new workers will go to Germany for on-the-job training,” he said. “It depends on the specific task.”
The first chunks of polysilicon are to come out of the plant in the second half of next year, the plant official said in a recent interview at the sprawling site off Lauderdale Memorial Highway.
This home owned by Adam Hutsell is the first home in this region with rooftop solar containing the latest version of Dow Shingles. This is a 3.8 kW system which was installed by RLI roofing with each section nailed to the roof.
Adam Hutsell is the developer of Twin Willows subdivision that will consist of half acre homes and townhouses. The entire complex will have Dow shingled roofs at no additional cost to the homeowner.

First Time in History that Solar Installations (36.5 GW) Greater than Wind Power Installations (35.5 GW)
Clean Edge predicting that solar PV will experience double-digit growth yearly and that by 2023 revenue growth in the PV industry will be $158.4 billion despite installed prices will continue to fall. The figure shows the projected gains in energy.
The Clean Edge report predicts an installed PV system price as low at $1.21 per watt by 2023. (maybe sooner) Clean Edge believes that in 2014 we will start to see “enlightened utilities begin to embrace distributed generation assets.” As rooftop solar continues its steady march towards adoption, utilities will continue to grapple with how to maintain healthy businesses in the face of declining electricity sales. “Some forward-looking utilities, if not fully embracing a distributed energy future, are making investments, forming partnerships, and acknowledging that the threat of DG might also be a business opportunity,” the report states. Clean Edge points to some examples of this that took place in 2013, such as Edison International’s purchase of SoCore Energy, a Chicago-based rooftop solar developer that does work in the commercial space. It also uses Duke Energy’s investment in Clean Power Finance as another example of utilities starting to think about profiting from distributed PV.

Energy Storage is the key to large scale solar plants as well as the smart grid. Here is an opportunity to find out where we are in energy storage and what will the future bring. More importantly, when low cost energy storage will hit the Walmarts of this world.
WHAT: This educational symposium will bring together speakers from industry, academia, and national laboratories to review the state of the art of lithium ion batteries and the future of electrochemical energy storage within the materials and device level and advances in characterization techniques for these devices and materials. There will also be a tour of the DOE Battery Manufacturing R&D Facility at ORNL. Electrochemical energy storage has become more and more important. In the past, electrochemical energy storage has been limited in size and energy density. Associated with its high cost for higher energy density, consumer electronics was the sole market for electrochemical energy storage until recently. Now, electrochemical energy storage transforms power tool, automotive, and electricity grid markets. Power tools benefit from the tremendous power capabilities of newly developed lithium ion batteries, automotive and grid scale storage which has become more available with new manufacturing technologies for large format devices. This educational symposium will bring together speakers from industry, academia, and national laboratories to review the state of the art of lithium ion batteries and the future of electrochemical energy storage within the materials and device level and advances in characterization techniques for these devices and materials.

Until now, those under TVA Green Partners program have been producing on-site energy from a solar panel has been treated much like any other activity reducing electricity use. Effectively the energy produced from solar is subtracted from the amount of energy used each month, and the customer pays for the remaining amount of energy consumed. The nations utilities are fearful of the financial effects of a reduced distributor income from the energy produced by solar. Increasing evidence suggests that the overall economic benefits to the utility’s electric grid may outweigh the loss of revenue. Xcel Energy, the Minnesota’s largest electric utility, shared estimations for the value of solar in its comments (to reduce the value) to the Public Utilities Commission in mid-February.
The solar market price includes eight separate factors, but the largest four account for the lion’s share of the value: 25 years of avoided natural gas purchases, avoided new power plant purchases, avoided transmission capacity, and avoided environmental costs.
The value of avoided fuel cost recognizes that utilities cannot buy natural gas on long-term contracts the way they can buy fixed-price solar energy, and it internalizes the risk of fuel variability that utilities have previously laid on ratepayers.
The avoided power plant generation capacity value recognizes that sufficient solar capacity allows utilities to defer peak energy investments (like Xcel’s recently requested three natural gas peaking power plants that an administrative law judge discarded in favor of distributed solar).
Avoided transmission capacity costs rewards solar for on-site energy production, saving on the cost of infrastructure and energy losses associated with long-range imports.
The environmental value may be the most precedent setting, because it means that when buying solar power under Minnesota’s value of solar tariff, a utility is for the first time paying for the environmental harm it had previously been socializing onto everyone else. This value is based on the federal “social cost of carbon” as well as non-carbon externality values adopted by the Minnesota Public Utilities Commission. The preliminary market value of solar estimate by Xcel Energy (14.5¢ per kilowatt-hour) for Minnesota. Here in Tennessee we have a better solar exposure and can expect the solar estimate will be larger. The cost of electricity for the homeowner is now 10 cents per kilowatt-hour. The estimated levelized cost of energy from rooftop solar presently is between 16 and 20 cents per kilowatt-hour.
Distributors with their buying power can reduce the levelized cost of energy from solar. Interestly Best Buy in partnership with SolarCity that’s now coming out of its pilot phase, roughly 65 Best Buy shops in the U.S. now offer solar arrays to their customers. The company’s solar-as-a-service offerings allow homeowners to go solar with little or no up-front costs.
For years, these critics — of solar photovoltaics in particular — have called renewable energy a boutique fantasy. A recent Wall Street Journal blog post continues the trend, asserting that solar subsidies take money from the poor to benefit the rich. this year the total photovoltaic capacity in the United States is projected to reach 10 gigawatts, the energy equivalent of several nuclear power plants. (By one estimate, photovoltaic costs crossed over to become cheaper than electricity generated by new nuclear plants about four years ago.)
Solar subsidies are dwarfed by historical taxpayer support of both fossil-fuel and nuclear-generated electricity. The International Energy Agency warns that continuing fossil-fuel subsidies contribute significantly to global environmental problems. The President has suggested that the 30% tax benefit for solar PV be eliminated or severely reduced. My reply is sure, when you remove all the subsidies for electric power of any type. Especially nuclear and fossil fuels.
To answer the critics that solar will depend on energy storage for it to be considered a dispatchable resources for electricity. Then why did TVA build one of the largest pumped stores before solar was on the horizon? It is simple, it is to balance supply and demand of electricity. it is the same reasoning for coal and nuclear plants where the plant says on line and the extra energy is sent to the store for use later. It is the same deal for solar.
An investment analysis by the financial services company UBS contends that an “unsubsidized solar revolution” has begun that could eventually supply as much as 18 percent of electricity demand in Germany, Spain and Italy. The report goes on to suggest that electric utility companies serving these markets may see their profits take a hit. The UBS analysts say that consumer-supplied solar electricity tends to reduce the spikes in electricity demand on the power grid (so-called peak load) from which these utilities have traditionally derived much of their revenue.
