US, California Release Roadmap for Solar Projects

State and federal officials sought Tuesday to bring order to California's boom for renewable-energy plants in the Mojave and other southern California deserts, releasing a roadmap covering 22.5 million acres that designates some areas for large-scale solar, wind and geothermal plants and others for conservation of desert habitat and animals.   "We have amazingly special places here," U.S. Interior Secretary Sally Jewell said in a news conference at a desert wind farm near Palm Springs with U.S. Sen. Barbara Boxer and other officials releasing the multi-agency draft plan.   By taking a look at the desert as a whole, Jewell said, the plan's designers are ensuring "the areas that should be protected are set aside. The areas that should be developed are streamlined" for building utility-scale renewable energy plants.   The release of the plan follows a renewable-energy building boom in southeastern California's deserts during the first term of the Obama administration, when the federal government gave billions of dollars in loans to developers placing sprawling, utility-scale solar projects in virgin desert.   The plan released Tuesday recommends designating a total of 2 million acres as appropriate sites for future solar, wind and geothermal projects. Another 4.9 million acres under the U.S. Bureau of Land Management would be among the areas set aside as conservation areas, if the draft plan is adopted.

Obama pushes energy efficiency, rural solar power

The Obama administration unveiled a slew of actions Thursday aimed at improving energy efficiency and increasing the use of solar power in homes and businesses, including $68 million in spending. The White House said the actions would reduce carbon dioxide emissions by nearly 300 million metric tons by 2030, the equivalent of 60 million cars’ emissions in a year. They will also save $10 billion in energy costs. The actions, together with commitments from states, communities, companies and others, are part of President Obama’s second-term push to reduce carbon emissions in an effort to mitigate climate change.   They follow other recent efforts to help the solar power industry, including a series of announcements in April to spur solar deployment, a White House-hosted summit on solar power and a May decision to install solar power panels on the White House.   The Department of Agriculture will spend $68 million on 540 renewable energy and energy-efficiency projects in rural areas, 240 of which are for solar power. Agriculture Secretary Tom Vilsack will announce the program, the White House said.  

Wind energy may help with grid stabilization

A new study from the National Renewable Energy Laboratory suggests that wind energy could stabilize the energy grid of the eastern U.S. Grid stabilization is often an issue where renewable energy is concerned. At times, clean energy systems can generate more electrical power than an energy grid can handle. Frequency regulation plays a major role in grid stabilization in the U.S., and wind turbines may be a new solution to the stabilization problem. Frequency regulation is the process through which the operators of an energy grid police the frequency of the infrastructure’s alternating current. Energy grids are strictly controlled throughout the U.S. and  are mean to put out electric currents with frequencies of 60 Hertz. In order to maintain this frequency, grid operators regularly change how much electricity is being funneled into the grid. Destabilization occurs when frequency is not properly regulated.   Wind turbines could be a new solution to this problem. According to the study from the National Renewable Energy Laboratory, wind turbines could be controlled to affect grid stabilization. The study shows that wind turbines can be tweaked using simple, commercially available mechanical parts. By changing the way these turbines generate electrical power, grid operators may be able to effectively control how much energy is coming into the grid.

North American Windpower reports U.S. offshore wind is "embryonic no more"

North American Windpower reports that the U.S. offshore wind industry is embryonic no more. Recent offshore wind news highlights also show that installations worldwide are picking up speed.   As of the end of July, the developer behind the 468 MW Cape Wind project had secured close to two-thirds of the roughly $2.5 billion needed for the wind farm, to be located off the coast of Cape Cod, Mass. In addition, the developer sold more than 77 percent of the projected output (363 MW) through stable, 15-year power purchase agreements (PPAs) at $0.187/kWh plus inflation. Construction is planned to commence in 2015.   Deepwater Wind (Providence, R.I.) has secured the entire output for the more modest 30 MW Block Island wind farm, located off the Rhode Island coast, with a 15-year PPA at $0.244/kWh. It also has preliminary contracts for turbines from Alstom and an installation vessel from Fred Olsen Windcarrier, and has received the go-ahead from the U.S. Army Corps of Engineers, the last federal agency to grant its approval. Deepwater says the Block Island wind farm has now been completely reviewed and approved by nine state and federal agencies, and expects “steel in the water” by 2015 with service to begin in 2016.   Cont'd...

Rethinking Solar Farms for the 21st Century: Tapping Ocean Space

An example is in a brave venture in India where a 10 kW prototype floating solar generation facility is being developed for placement in a pond. Pilot projects of this nature have also started to take shape in countries like Japan, France and Australia.

Strange bedfellows: Solar power meets oil drilling

A company that uses solar energy to recover crude has scored big financing from some major oil players—and highlights a growing niche of global oil exploration.   GlassPoint Solar last week landed a $53 million investment from Royal Dutch Shell and the sovereign investment fund of Oman for its enhanced oil recovery (EOR) technology. In a twist of irony, GlassPont's technology runs on solar power, which produces steam to help pump more fossil fuel from conventional crude plays.   GlassPoint has been using this technique in Oman since 2012, and it helped the firm score more than double its initial funding. Given the age of its oil fields, Oman relies on EOR—a complex process that extracts more oil than traditional drilling—to boost production.   Although EOR is common to the oil industry, using the power of the sun "is expanding very rapidly, and is a very new technology" said Rod MacGregor, GlassPoint's CEO, in an interview. "This application looks like the next step for solar."

World's Largest Single Rooftop Solar Power Project Commissioned In India

Indian solar energy companies are fast delivering world-class solar power projects as the market expands based on favorable regulatory and policy outlooks.   India’s largest engineering, procurement and construction (EPC) company in the solar power market has just commissioned the world’s largest single rooftop solar photovoltaic power project. The 7.52 MW solar power plant has been commissioned in the northern state of Punjab.   Larsen and Toubro has been involved in the construction of several solar power projects that will be seen as major milestones in India’s solar power infrastructure expansion. The company reported that it has already commissioned or is working on solar power projects with total capacity of 400 MW. This includes the largest solar thermal power plant in Asia – Reliance Power’s 125 MW linear Fresnel power project located in Rajasthan. The company has also worked on several other solar power projects under the National Solar Mission.   Punjab has some of highest power tariffs in the country. Being an agricultural state, power supply to the farmers is of paramount importance, while industries and commercial users are low on the priority list. In the absence of adequate supply, the utility procures power from short-term markets, which increases the overall costs which, in turn, is passed on the industrial and commercial consumers.

UC makes largest solar-energy purchase by U.S. higher education institution

The University of California announced Monday that it signed two power-purchase agreements that, combined, will provide 206,000 megawatt hours of solar energy per year — the largest solar energy purchase by any higher education institution in the U.S.   This energy is equivalent to powering 30,000 homes and will avoid producing more than 88,000 metric tons of carbon dioxide per year. The initiative will provide power for UC Irvine, UC San Diego and UC San Francisco, along with their medical centers, in addition to UC Merced and UC Santa Cruz.   Mark Byron, the university’s wholesale electricity program manager, described the purchase as a “nexus” with UC President Janet Napolitano’s sustainability initiative, which was released November. One of the main components of the initiative is to be carbon neutral by 2025.   “By injecting solar energy, we’re making sure our portfolio comes from green energy,” Byron explained.   The university signed the 25-year agreements with Frontier Renewables, a San Mateo-based company focused on solar energy technology. Two solar fields will be built in Fresno County as part of the project.

Sharp Considering Sale Of U.S. Solar Energy Unit

Sharp Corp is looking to sell its U.S.-based solar energy development unit Recurrent Energy, Bloomberg reported on Monday, as the Japanese firm winds down its involvement in the solar industry to focus on profitable businesses. Sharp paid $305 million in cash in 2010 to acquire Recurrent Energy. Selling the company now would help Sharp to raise capital as it struggles to raise its equity ratio to a healthy level. This year, Sharp shut down its UK solar plant and also pulled out of a venture with Italian energy firm Enel SpA  to make solar panels and generate solar power.
