Sniper attack on power grid

A recently revealed criminal attack upon a Pacific Gas & Electric (PG&E) substations has given lawmakers pause and turned the subject not just to cybersecurity for electric power infrastructure, but physical security.
The Wall Street Journal reported a previously unpublicized 52-minute assault by snipers on PG&E’s Metcalf transmission substation. The assailants fired some 100 bullets into the substation, which knocked 17 transformers out of service.
PG&E was able to stave off a loss of service by diverting to other T&D assets, but utility workers had to spend 27 days repairing the shooters’ damage to the substation area.
The FBI, which is serving as lead agency on the investigation, does not believe the attack was an act of international terrorism. Jon Wellinghoff, who led FERC at the time, said he believed the incident was domestic terror.

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.”



Featured Job: Sperry Van Ness | RM Moore 50kW Solar Installation

ARiES Energy completed a 50kW solar installation at Cycle Gear, a motorcycle gear retail store in the Cedar Bluff area of Knoxville, Tennessee.  This is the second solar

project that ARiES Energy has completed for property owner Sperry Van Ness | RM Moore, a leading commercial property manager in Knoxville.  The system is expected to produce 62,500 kWh per year.

With 345 Stion frameless panels, Aurora inverters and a frameless racking system, this system is ready to go! ARiES Energy also installed a energy monitoring system, so the property owners can monitor their energy production, giving them the power to make educated decisions about future energy-efficiency upgrades.

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.

Kudos to Ted Wampler, Elizabeth Eason and to Alcoa

Elizaberh EasonThe U.S. Green Building Council’s (USGBC) East Tennessee Chapter at its third annual Green Light Awards recognized local businesses and individuals that have had a major influence on sustainability in this region. Alcoa was given a premier recognition for its efforts to curb energy use. Alcoa’s energy efficiency group is based in Knoxville area and has set an aggressive goals of reducing its carbon footprint and encourages their employees to volunteer in projects dedicated to the environment.

Ted Wampler received the Green Leader Award for Wampler’s Farm Sausage which has revamped its plant to reach a net zero energy consumption with its half megawatt solar array and novel biomass burner that converts biomass pellets to hydrogen and other combustible gases to energize an electric generator supplying power to the plant. The Wamplers also donated a 50 kilowatt solar system to the Knoxville Zoo.

Elizabeth Eason, architect, was also awarded a Green Leader Award for her dedication to promoting sustainable building practices and as a founding member of the local USGBC chapter.

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.

New Farm Bill Preserves Core Clean Energy Programs

After three years of stops and starts, debate and negotiations, the Congressional Farm Bill Conference Committee has released a compromise bill between the House and the Senate that includes mandatory funding for a downsized Energy Title, including the Rural Energy for America Program (REAP) and Biomass Crop Assistance Program (BCAP).

If passed by Congress, the funding for REAP and BCAP in the compromise would ensure the popular programs will continue to support diverse technologies for renewable energy and energy efficiency initiatives in farm communities across the nation. REAP offers grants and loan guarantees for renewable energy and energy efficiency projects owned by farmers, ranchers, rural small businesses and rural electric co-ops. BCAP provides incentives to jump start sustainable energy crops that also provide conservation benefits.

“While the overall Energy Title funding has been reduced, this compromise provides the certainty for renewed growth in rural energy projects under both REAP and BCAP,” Olsen said. The bill announced late Monday by the Farm Bill Conference Committee includes $881 million for Energy Title programs over ten years.

Elon Musk’s SolarCity taps the power of the crowd to reduce cost of distributed solar

Elon Musk gets solar. (Simon Dawson/Bloomberg)

Elon Musk’s role as chairman and primary shareholder in SolarCity — a solar energy company run by his cousins – that’s getting a lot of attention these days. SolarCity was already the first to market with bonds backed by the revenue from rooftop solar projects, making it possible for institutional investors to invest in the success of future solar projects. (It’s essentially the same logic that makes it possible for investors to buy mortgage-backed securities, thereby creating a robust housing market). SolarCity’s latest move, announced this week, is the ability for individual investors also to participate in this market. SolarCity is essentially creating a new Web-based platform to enable the crowd to make money off other people installing solar panels. Company to sell bonds backed by rooftop solar panels, plans to offer similar products to individual investors. SolarCity expects to introduce within six months an online system for retail investors to provide debt for SolarCity’s rooftop power plants. The system will provide one of the few opportunities for individuals to back renewable-energy projects, which generate steady revenue from selling electricity. Chief Executive Officer Lyndon Rive said “We expect billions of dollars of investment through this platform”.
