On Monday, as First Wind announced its 69-MW Kawailoa Wind Project had gone into commercial operations on Oahu, other news underscored the difficulty the island state faces in trying to substitute renewables for expensive, imported fossil fuels.

The Desertec Industrial Initiative (Dii) oversees a $508 billion initiative to establish 6,500 square miles of concentrated solar power plants in the vast African and Middle Eastern deserts. Those plants are expected to furnish a fifth of Europe’s power needs by 2050, but in recent weeks the Dii has seen the exit of two of its 57 partners from 16 countries and a project held up by the Spanish government.

Renewable energy projects installed on potentially contaminated lands, landfills, and mine sites have increased by 40% since 2008, a new list released last week by the Environmental Protection Agency (EPA) shows. Solar photovoltaic (PV) systems make up the bulk of about 184.7 MW installed at 60 sites in 25 U.S. states.

The influx of cheap Chinese-manufactured solar panels has upended the solar industry in more ways than one. The saga offers some lessons on what to do about LNG exports.

The first problem with high renewable penetration is that wind and solar are not dispatchable.

The California Public Utilities Commission (CPUC) last week approved a deal involving the state’s major utilities and renewable energy advocates that is  aimed at streamlining the process for connecting distributed generation (DG) resources to the grid. The CPUC’s action will make it easier for small amounts of distributed resources—such as rooftop solar photovoltaic (PV) systems—to connect to the grid. The agreement also revises upward the amount of DG that can be connected to a specific power line segment without the need for supplemental studies.

The title of world’s largest operating solar photovoltaic (PV) power plant goes to Arizona. On Monday, First Solar Inc. announced that the Agua Caliente solar project has achieved a peak generating capacity of 250 MW connected to the electrical grid. The project, under construction in Yuma County, will have a total capacity of 290 MW when completed.

The Department of Energy (DOE) on Wednesday announced its SunShot Prize, a new competition to make it faster, easier, and cheaper to install rooftop solar energy systems. A total of $10 million in cash awards are available to the first three teams that repeatedly demonstrate the non-hardware costs, or price to plug in, can be as low as $1 per watt for small-scale photovoltaic (PV) systems on American homes and businesses.

Congress has returned from its summer break. As the House prepares to vote on its Upton-Stearns "No More Solyndras Act," lawmakers also expect to focus on a bill that could prohibit finalization of any Environmental Protection Agency (EPA) power plant rules that curb greenhouse gas emissions while carbon capture and storage technology is commercially unavailable. House Democrats, meanwhile, called for hearings to examine the impacts of climate change on the nation’s generators.

Droughts, unreliable gas imports, and protests against proposed projects have hampered the Chilean power sector and its largest economic driver, the copper-mining industry. Recent policies designed to foster more reliable supplies are a move in the right direction, but remaining obstacles are formidable.

The U.S. Trade Representative on Monday asked the U.S. International Trade Commission (ITC) to investigate how U.S.-provided renewable energy services affect development of renewable energy projects worldwide. The ITC’s report, expected by June 28, 2013, will focus on the development, generation, and distribution of renewable energy—specifically onshore and offshore wind and solar energy.

Washington, 17 August 2012 — Poor Cliff Stearns. The soon-to-be-former Republican congressman from Florida found out Tuesday that voters in his district didn’t much care about the ruckus he’s been raising about the Obama administration and its funding of the failed Solyndra solar photovoltaic maker.

Solid oxide fuel cells (SOFCs), which oxidize a fuel to produce electricity, have received much attention of late for the technology’s myriad benefits, including high efficiency, long-term stability, fuel flexibility, and low carbon emissions—all at a relatively low cost.

“If you build it, they will come” has proven a risky strategy for some smart grid projects. One of California’s largest investor-owned utilities faced the opposite challenge—customers whose behaviors necessitated a smarter grid. Customer involvement in and support for smart grid plans is a major reason SDG&E’s smart grid efforts continue to garner accolades, including the 2012 POWER Smart Grid Award.

Global solar trade tensions escalated on Friday as the Ministry of Commerce of the People’s Republic of China announced it would launch both anti-dumping and countervailing investigations on imports of solar-grade polysilicon from the U.S. and an anti-dumping probe on South Korean polysilicon imports. Germany on Friday, meanwhile, said it would support its solar industry in anti-dumping action against China.

In May—as a trade war raged between Chinese solar panel manufacturers and exporters and their counterparts in the U.S. and the European Union concerning the world’s plummeting crystalline silicone photovoltaic module prices—a 28.8-MW thin-film copper indium gallium (di)selenide (CIGS or CIS) solar power plant came online. Developers Solar Frontier, the world’s largest manufacturer of CIS […]

India’s long-term annual economic growth rate is projected at over 7%, and the country is investing in its hydroelectric, nuclear, and renewable resources. However, the primary fuel used to produce electricity remains coal, and the government has ambitious plans to significantly increase coal-fired capacity. Those plans have been challenged by a number of unexpected factors that threaten to stifle India’s economic growth.

Panelists at ELECTRIC POWER discussed how U.S. utilities choose renewable power generation technologies based on their geographic locations, state requirements, economics, and other criteria—including reliability and federal regulations.

Combining concentrating solar power (CSP) with thermal energy storage shows promise for increasing grid flexibility by providing firm system capacity with a high ramp rate and acceptable part-load operation. When backed by energy storage capability, CSP can supplement photovoltaics by adding generation from solar resources during periods of low solar insolation.

The operation of solar thermal power plants differs substantially from that of fossil-fired plants, as the sun determines the generation rather than market demand. However, design of the power island to minimize water usage is very similar to that of a fossil plant. This renewable technology requires renewed thinking of its water systems’ design.

Chinese state entity State Grid Corp. of China (SGCC) and battery maker BYD in January said they had finished construction on what they call “the world’s largest battery energy storage station”—a project in Zhangbei, Hebei Province that combines 100 MW of wind and 40 MW of solar capacity, a smart power transmission system, and 36 MWh of energy storage in arrays “larger than a football field.”

Two identical 50-MW parabolic trough plants with thermal storage in Cadiz, in the south of Spain, began operating this January.

The ambitious Desertec project—a $9 billion initiative to develop, harness, and transmit 2,000 MW of renewable power from North Africa and the Middle East to Europe by 2050—has been trumped by a vaster concept that spans Asia and Australia.

For the past 15 years, Vietnam has enjoyed enviable gross domestic product increases, averaging 7% annually. That kind of economic growth increases power demand, but financing new capacity remains a challenge. Reaching its ambitious capacity growth goals will require Vietnam to expand its financing and vendor base, attract foreign investment, and ensure future fuel supplies in a region thick with competition for those resources.

Of the $35.9 billion in loan guarantees awarded by the U.S. Department of Energy (DOE) since 2009, roughly $26.5 billion have financed nuclear and renewable power projects across the nation through the Section 1703 and 1705 loan guarantee programs.

Brazil’s power industry has long been dominated by its vast hydro resources, which historically have accounted for over 80% of the country’s generation capacity. With engineering marvels like the massive Itaipú dam and the proposed Belo Monte project, the country is a leader in the development and use of hydroelectricity on a grand scale. But as the 2001 energy crisis proved, dependence on a single source leaves the country vulnerable to severe shortages. Thanks to government programs designed to take advantage of the country’s favorable climate, Brazil is committed to diversifying its energy mix while continuing to maintain a renewable energy focus.

A trade row between the Chinese government and solar panel makers around the world intensified in December. As China’s Ministry of Commerce refuted allegations that the Chinese government uses illegal subsidies, discounts for raw materials, preferential loans, tax incentives, and currency manipulation to drive down prices and amplify exports of Chinese solar photovoltaic (PV) panels, the U.S. International Trade Commission (ITC) affirmed the U.S. solar industry is “materially injured” by imports, at “less than fair value,” of Chinese crystalline silicon PV cells and modules.

The POWER editorial staff’s picks for the most significant stories of 2011.

At home and abroad, U.S. military microgrid and smart grid projects are driven by energy security concerns. The pace of such projects, however, can be slow, and the potential for civilian grids to benefit from lessons learned and technologies developed for these important installations may be limited.

Driven by policies to limit carbon emissions, as well as government subsidies, the share of worldwide nonhydro renewable power is set to grow from just 3% in 2009 to 15% in 2035, the International Energy Agency (IEA) forecasts in its recently released World Energy Outlook 2011. Under the same scenario—which assumes that carbon pricing, explicit […]
