KKR and Google to Invest in Six U.S. Solar Power Plants

KKR & Co. and Google Inc. have struck a pact to invest about $400 million in six solar-power plants being built by Recurrent Energy LLC in California and Arizona. Development of the plants has been under way for years and they are expected to go online and begin producing power in January, the people said.

The plants—five in southern California and one in Arizona—are designed to produce about 106 megawatts of electricity combined, or enough to power about 17,000 U.S. homes, they said. San Francisco-based Recurrent, which will continue as their operator, has struck long-term power supply agreements with three buyers for the electricity they’re expected to churn, the people said.

Tennessee Valley Authority Makes Major Coal Plant Retirement Announcement

November 14, 2013. Today at a board meeting in Oxford, Mississippi the Tennessee Valley Authority (TVA) Board of Directors voted to retire units at three of its coal plants. This will affect coal-burning units at the Colbert and Widows Creek plants in Alabama and the Paradise plant in Kentucky.

TVA’s commitment to retire units at three coal plants will protect customers from rising energy bills as coal prices increase, and protect families from the health threats posed by coal pollution. According to the Clean Air Task Force, pollution from the Colbert coal plant in Alabama alone contributed to 940 asthma attacks, 83 heart attacks, and 57 deaths per year.

As the nation’s largest public power provider, TVA was first established to bring innovation to the Valley and address a wide range of environmental, economic and technological issues. As it transitions away from coal, TVA should remain true to its founding principles by bypassing natural gas or any other dirty fossil fuel that will continue to exacerbate environmental and public health issues.

TVA is now mapping out its next Integrated Resource Plan (IRP), the strategy document outlining the utilities energy portfolio for the next 20 years. As TVA works to protect public health and decrease energy costs by moving away from coal, the utility can also commit to speeding the deployment of the most promising and cost-effective renewable technologies, like wind and solar, in its IRP. Wind and solar power are currently experiencing fast growth while simultaneously becoming more cost-competitive with TVA’s other fuel choices.

4 Factors Driving the Marriage of Solar and Energy Storage

A solar-powered microgrid demonstrates the potential of coupling big batteries with commercial solar. What if you could finance the energy storage equipment, much the way solar panels are financed, and the batteries provided a revenue stream? Modern grid-scale battery systems are only put in place to save money or provide services to the grid. An example is one installation that includes 402 kilowatts’ worth of solar canopies in the parking lot and, in a twist that differentiates it from most commercial solar projects, a shipping-container-sized battery from startup Solar Grid Storage. Here in Knoxville we have a battery enhanced solar powered car-charging station located at the EPRI location off Dutchtown Road. On a daily basis, though, the battery will deliver frequency regulation services to the local wholesale grid. By providing quick bursts of power to keep a steady balance between supply and demand, battery owner Solar Grid Storage will earn money that is normally paid to natural gas power plant operators.

Here are the factors that are driving the combination of commercial solar and energy storage.

1. The technology is there. Better batteries are in development that will lower cost.

2. The economics can make sense. AES Energy Storage, for instance, provides frequency regulation services at a wind farm in West Virginia, buffered by a 32-megawatt lithium-ion battery bank. Revenue comes from reducing demand charges by using stored energy during peak hours. Most of its customers are in California, which has subsidies for distributed energy storage. By contrast, the desire to have emergency power has become a priority in East Coast states hit hard by Hurricane Sandy and other severe storms.

3. Solar installers want storage — if it pencils out. Military bases and island locations that rely on diesel generators are obvious candidates. A battery can smooth out the flow of power that panels provide to the local grid and address issues, such as the drops in voltage that come when clouds pass over. Batteries could also enable solar installations in places, such as farms, which would have required costly upgrades to the grid infrastructure. The contracts to finance a combined solar and storage system are complex and need to become more standardized, as power purchase agreements are, said president Scott Wiater of Standard Solar. Financing these types of systems is still relatively new and developers need to find customers willing to try not only solar, but also relatively new energy storage technology.

4. NRG Energy Inc. and Exelon Corp.’s Constellation unit say interest in combining solar power with battery storage has soared in the year since Hurricane Sandy knocked out power to millions of homes and businesses on the East Coast. They are among more than a dozen solar providers that have introduced or enhanced in the past year systems that combine rooftop solar panels that generate power and batteries that retain electricity to use later.
People with solar-powered homes and businesses were frustrated to discover that losing power from local utilities also knocked out the inverters that connect rooftop panels to the grid, leaving them unable to tap the electricity they were producing. Adding battery storage solves that problem, said Tom Doyle, chief executive officer of NRG’s solar unit.

It’s also a growing threat to utilities.
“When Sandy came along we really didn’t have a product to keep solar power flowing during blackouts,” Doyle said in an interview yesterday at the Solar Power International conference in Chicago. “Now we can install systems that continue operating when the grid fails, and the costs are coming down.”
Battery storage can add more than 20 percent to the cost of a typical 10-kilowatt solar system for a four-bedroom home, Brendon Quinlivan, director of solar development at Constellation, said in an interview.

Tennessee receives $5M for solar energy

Tennessee has received $5 million to support research and development of solar energy from the U.S. Department of Energy’s SunShot Initiative.
The funding is part of a $60 million investment in the initiative, which is designed to lower the cost of solar electricity, advance grid integration of solar energy systems and support the growth of the solar energy workforce in the country.
According to a DOE statement, the solar industry has created nearly 20,000 new jobs. An estimated 119,000 people are employed at 5,000 solar energy companies across the U.S. The funding will help provide training for engineers, utility workers and for students.

residential solar installations is stronger and broader than expected

Study Says Most Americans Would Consider Residential Solar. A study from research firm Market Strategies International finds that interest in residential solar installations is stronger and broader than expected among American consumers, even when those consumers are educated on associated costs. With few exceptions, this interest is strong across virtually all age and income groups.

Survey participants were informed that, “The cost of a typical home solar system is about $30,000 and provides about 60% of a home’s electricity needs. The final costs of a solar system can be reduced through a federal tax credit that allows purchasers to deduct 30% of the systems’ cost from their income taxes. Some states also provide financial incentives for solar installations.”

According to the survey, the information made 51% of respondents more interested in home solar systems, with consumers older than 55, again, the only group to show less interest. A majority of respondents across every income group continued to show interest – even low-income households with incomes under $25,000.

“It’s pretty clear that most utilities in the U.S. have to figure out an effective strategy for working with their customers who want solar power,” says Jack Lloyd, senior vice president of energy at Market Strategies. “Companies will take different approaches in adapting to the situation, but rooftop solar appears to be poised to move beyond its early adopter niche and become a more mainstream phenomenon.”

Japan Next-Generation Farmers Cultivate Crops and Solar Energy

Farmers in Japan can now generate solar electricity while growing crops on the same farmland. This co-existence or double-generation is known as “Solar Sharing” in Japan. The concept was originally developed by Akira Nagashima in 2004, who was a retired agricultural machinery engineer who later studied biology and learned the “light saturation point.” The rate of photosynthesis increases as the irradiance level is increased; however at one point, any further increase in the amount of light that strikes the plant does not cause any increase to the rate of photosynthesis.

By knowing that too much sun won’t help further growth of plants, Nagashima came up with the idea to combine PV systems and farming. He devised and originally patented special structure, which is much like a pergola in a garden. He created a couple of testing fields with different shading rates and different crops. The structures he created are made of pipes and rows of PV panels, which are arranged with certain intervals to allow enough sunlight to hit the ground for photosynthesis.

Based on the tests conducted at his solar testing sites in Chiba Prefecture, he recommends about 32% shading rate for a farmland space to reach adequate growth of crops. In other words, there is twice as much empty space for each PV module installed. Takazawa installed 348 PV panels on a small 750 square-meter of farmland. PV panels are installed on pipes, which are 3-meter high from the ground. Rows of PV panels are installed every 5 meters. Under the PV system, Takasawa’s father has been cultivating peanuts, yams, eggplants, cucumbers, tomatoes, and taros and will cultivate cabbages during the winter. These vegetables are sold at a nearby street and consumed by his neighbors.

Many have questioned stability and durability of the PV structure for solar shared family. Nagashima stated that his systems, which are made of thin pipes without concrete footings, even withstood strong winds and earthquakes during the Fukushima Tsunami disasters in 2011. These systems are extremely lightweight and installation of PV panels are spaced out, allowing air to flow through between the panels. This will eliminate concern that the panels will receive wind load and be blown away, therefore, reducing the need for complicated and expensive mounting hardware.

The Volkswagen XL1 made its U.S. debut at the Chattanooga Convention Center today.

[""
The Volkswagen XL1, the most fuel-efficient and aerodynamic production car in the world, made its U.S. debut at the 23rd Annual Society of Environmental Journalists (SEJ) Conference at the Chattanooga Convention Center today. The XL1 offers an estimated European combined fuel consumption rating of 261 mpg (more than 200 mpg estimated in the U.S. cycle) and can cover up to 32 miles as a zero-emissions vehicle in all-electric mode.
“The XL1 offers a glimpse into Volkswagen’s present and future eco-mobility capabilities, and highlights the ultimate successes of ‘Thinking Blue,’” said Oliver Schmidt, General Manager of the Engineering and Environmental Office (EEO), Volkswagen Group of America, Inc. “Volkswagen is proud to debut this ultra-fuel-efficient vehicle before the Society of Environmental Journalists, a group that shares in our commitment to environmental stewardship.”
In addition to the XL1 display, Volkswagen’s participation in the SEJ Conference included a tour of its LEED® Platinum-certified Chattanooga manufacturing plant and solar park; test-drives in its line of eco-friendly cars, such as the e-Golf, Passat TDI Clean Diesel and Jetta Hybrid; and a bird-watching expedition on Volkswagen Chattanooga’s sanctuary grounds.

Leading Utilities Recognize the Need for Solar Energy as Older Nuclear Plants Pass Their Economic Viability

CEOs from opposite sides of the country also spent much time discussing the increasing role of renewable energy and distributed generation.

California is known for having the nation’s most ambitious renewable energy mandate while North Carolina, where Duke is based, also has a growing solar energy presence.
Edison CEO Ted Craver said electric utilities would be mistaken to dismiss distributed generation as merely a “fringe” business in the future. The Edison chief said his company initially started in the field by supplying big solar arrays for “big box” stores.

“A lot of this is really experimental,” Craver said. Utility subsidiary Southern California Edison (SCE) used to rely on industrial customers for one-third of its load but that is now probably closer to 10 percent, Craver said.

While some argue that California policy has been inhospitable to heavy industry, it’s important to realize that manufacturers are looking to generate more of their own power, Craver said.
The utility, SCE, is also investing more in the transmission side of its business to accommodate the growing role of distributed generation in California.

Duke is developing a variety of resources in its service territories — including new combined-cycle and peaking units in Florida — to help compensate for retirement of the Crystal River nuclear plant and potential coal units retirements as well. California is known for having the nation’s most ambitious renewable energy mandate while North Carolina, where Duke is based, also has a growing solar energy presence.
