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.

Farmers, ranchers and rural small businesses can apply now for grants and loan guarantees for clean energy projects under the Rural Energy for America Program – or REAP. REAP was renewed in the 2014 Farm Bill and supports a wide range of energy efficiency and renewable energy technologies, including wind, solar, biogas, biomass, small hydroelectric, geothermal, tidal, wave, and hydroelectric technologies.
An official notice of funding availability is expected in early April, with an application deadline 60 days later. This notice would be for funds from the 2014 appropriation plus funds carried over from previous years (total about $28 million). When the final REAP rule is announced, possibly in June or July, a second funding announcement will be issued for the 2014 mandatory funding ($50 million) from the new Farm Bill. Applications submitted but not funded in the first round will be considered in the second round.
Applicants should also be sure to check in early with the state staff of USDA rural development. They can answer questions, provide useful advice and may need to visit the project during the application process.

The Natural Resources Defense Council and the U.S. utility industry’s trade group are jointly calling for a new rate structure to account for customers that generate their own power with rooftop solar systems. “We need the grid and need to improve it in ways that support clean energy and distributed resources,” says Nathanael Greene, director of renewable energy policy at the NRDC in New York. Owners of rooftop solar panels “must provide reasonable cost-based compensation for the utility services they use,” says both groups. In exchange, utilities must simplify the process of connecting systems to the grid and compensate owners “fairly for the services they provide.”
Under the current policy, known as net metering, utilities must purchase excess electricity generated by customers’ solar panels. Both groups want that policy to continue, with a new mechanism that would cover utilities’ fixed costs. Still, they agree that changes to utility rate structures would improve energy-efficiency programs and expand rooftop solar. They recommend allowing utilities to recover the costs of maintaining and improving the grid in a way that’s not tied to the amount of electricity they deliver to consumers.
“We want regulators to decouple grid charges from volumetric consumption,” Greene said. “Then the utilities can’t use net metering as an excuse for the high fixed-cost charges they want.”
Comment from S. Levy:
It is my personal belief that ratepayers are going to be supplied by smart metering in the near future. As a result of smart metering, the electric utility industry will begin setting different rates based on their peak loads during the day and evening hours. The purpose being to lower the peak demand that occurs between the hours of 5 pm and 9 pm. So, they will charge the consumer more during the peak hours to reduce the peak load and with it, the resources to produce and deliver that higher power level.
It’s all about demand charge management and that demand charge management can result in a 10 percent to 20 percent bill savings. That is if the homeowner controls the use of high wattage appliances and home electric heating and cooling of the home and their water heater. Automation is available today that can control these energy users.

The solar installation at Volkswagen Chattanooga confirms the awarding of the highly-coveted LEED Platinum certification to VW by the U.S Green Building Council in late 2011. At that time, the Building Council called the Chattanooga manufacturing facility “the world’s greenest auto plant” and noted it was the first automotive manufacturing plant in the world to receive the top LEED certification. Today, the Chattanooga plant remains the only auto plant worldwide to earn the LEED Platinum certification.
The electricity produced from the solar park is expected to meet 12.5% of the energy needs of Volkswagen’s Chattanooga manufacturing plant during full production and 100% during non-production periods. The plant covers 1.9 million square feet and employs more than 3,000 people who manufacture the highly-acclaimed Volkswagen Passat sedan. For Volkswagen, the solar park in Chattanooga will rank as the automaker’s largest photovoltaic installation worldwide.
Silicon Ranch (www.siliconranch.com), which develops and operates solar energy solutions tailored to meet its customers’ needs, will own the solar park and sell the electricity to Volkswagen under a 20-year Power Purchase Agreement (PPA). Phoenix Solar Inc. (www.phoenixsolar.com), the U.S. subsidiary of Phoenix Solar AG (www.phoenixsolar-group.com), provided engineering, procurement and construction (EPC) services in building the solar park over the last six months.
Frank Fischer, CEO and Chairman of Volkswagen Group of America, Chattanooga Operations LLC, said, “We are proud to power up the biggest solar park of any car manufacturer in North America today. The solar park,” he said, “is another proof point of Volkswagen’s worldwide commitment to environmental protection under its ‘Think Blue. Factory’ philosophy, a broadly focused initiative for all Volkswagen plants to achieve more efficient use of energy, materials and water and produce less waste and emissions.” Mr. Fischer added, “Powering up the solar park also validates the awarding of the LEED Platinum certificate to Volkswagen Chattanooga, which is still the only car factory in the world that has earned such an honor.”
Restoration Services Inc. is partnering with Vis Solis to build a one megawatt solar farm at the East Tennessee Technology Park, former K-25 site, on a site leased from Community Reuse Organization of East Tennessee (CROET). The solar power generated electricity will go to the TVA grid to run the equivalent of nearly 150 homes. Gil Hough, manager of the renewable energy division of Restoration Services says that is almost a done deal. Construction is expected to start in April. What makes this solar installation unique is the use of Vis Solis tracking of the sun to always keep the panels pointed towards the sun for maximum performance. The increase in power production can be as high as 30% over the conventional fixed arrays.
