The Red Faces of the Solar Skeptics

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.

Apply now for 2014 Rural Energy for America Funding

solar farming2Farmers, 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.

Natural Resources Defense Council calls for compensation for customers with solar PV

NRDC

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.

Volkswagen Chattanooga Powers Up Largest Solar Park In Tennessee

VW solar plant

Volkswagen’s Chattanooga plant powered up the largest single solar installation at an automotive manufacturing facility in the United States and the biggest solar installation in the state of Tennessee. At a dedication ceremony here, dignitaries today flipped a giant light switch to signal the official opening of the “Volkswagen Chattanooga Solar Park”, built on Volkswagen’s compound in Chattanooga.

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.”



A One Megawatt Project Planned for Oak Ridge

Restoration SevicesRestoration 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.

Every Four Minutes, Another American Home or Business Goes Solar

Obama_in_Georgetown-200x150This was the quote from the President’s State of the Union address this past week. He then suggested, as he has before, that we divert tax breaks from fossil fuel industries to fund more development of “fuels of the future.” Even Forbes stated that the shift in supports “While that policy makes some sense, it needs to be pegged to commodity prices..” There has been a split in the Republican Congress members from a solid wall against renewables, to one where many of the party are now supporting wind, solar and biomass. Expect the final version of the Agriculture bill to contain substantial support for biomass as an energy source. We do need more research into future solar development. We need to concentrate on supporting increases in conversion efficiency for solar PV.

We need the Federal Government to fund a more automated solar foundry in the Gigawatt class which would demonstrate producing solar panels for less than $0.30 per watt. We need to automate the installation of racking and solar panel mounting for solar plants. We have produced panels with 30% and higher efficiencies, but the cost was prohibitive. Focussing on higher efficiency along with a massive production facility will result in lower panel cost in large scale manufacturing. The windpower from Texas can be sent to TVA region for about four cents per kilowatt-hour according to recent testimony before the TVA resources council. Solar has to aim for that same price.
