  • California Governor Signs 33% RPS Law, Eyes More Ambitious Target

    California’s Governor Jerry Brown on Tuesday signed into law SBX1-2, a law that increases the state’s renewable portfolio standard (RPS) target from 20% in 2010 to 33% by 2020—the most aggressive goal in the nation. In his signing message, Brown said he would pursue even more far-reaching targets, pushing the RPS to 40% in the “near future.”

  • EPRI: Deployment of Fully Functional Smart Grid Could Cost up to $476B

    A report released last week by the Electric Power Research Institute (EPRI) that broadly assesses the costs and benefits to modernize the U.S. power system suggests that investments needed to deploy a fully functional smart grid range between $338 billion and $476 billion—but could result in benefits of $1.3 trillion to $2 trillion.

  • AWEA: Added Wind Capacity Plunged Nearly 50% in 2010 Compared with 2009

    In 2010, only 5,116 MW of nameplate wind capacity was added in the U.S.—a nearly 50% drop from the record 10,000 MW installed in 2009, the American Wind Energy Association (AWEA) said in its newly released annual report. The industry group said, however, that wind power capacity added in 2010 made up 26% of all new generating capacity added in the U.S.—second only to natural gas.

  • DOE, GE Make Hefty Investments in Solar Power

    Solar power in the U.S. received multiple boosts in the past week as the Department of Energy (DOE) finalized $2.7 billion in loan guarantees for solar projects in California while making available $170 million in funding for solar photovoltaic (PV) technologies, and GE Energy announced plans for what it said will be the biggest solar PV panel factory in the U.S.

  • Japan Raises Daiichi Accident Rating to Chernobyl Level

    On Tuesday, Japan’s Nuclear and Industrial Safety Agency (NISA) provisionally raised the accident rating for three reactors at the crippled six-unit Daiichi nuclear plant in Fukushima Prefecture to Level 7—making it a “major accident” and putting in on par with the 1986 Chernobyl accident in the Ukraine. And today the Tokyo Electric Power Co. (TEPCO) confirmed damage to spent nuclear fuel rods stored in the Unit 4 building.

  • Don’t Close the Government, Abolish DOE

    By Kennedy Maize Washington, D.C., April 11, 2011 – Now that the children of all ages have stopped holding their breath until the government turns blue, we can get back to more important subjects, such as what the federal government should look like, how it should relate to the states, how much should it spend, […]

  • TEPCO Stops Radioactive Leaks Amid an Array of New Threats

    In a major breakthrough at the crisis-stricken Fukushima Daiichi power plant, engineers who had been desperately struggling to contain radioactivity at the plant’s units today managed to stop highly radioactive water leaking into the Pacific Ocean. Tokyo Electric Power Co. (TEPCO) says, however, that it will continue to pump contaminated water into the sea for lack of storage capacity, and efforts are under way to begin injection of nitrogen into the primary containment vessel of Daiichi 1.

  • EPA Takes Action on N.J. Complaint About Pennsylvania Plant Pollution

    The U.S. Environmental Protection Agency (EPA) on Thursday proposed a rule—granting a Clean Air Act petition filed by New Jersey’s Department of Environmental Protection (DEP)—to limit sulfur dioxide emissions from a 420-MW coal-fired power plant in Pennsylvania that it alleged was adversely impacting air quality in four New Jersey counties.

  • Progress to Shut Down Coal Plant Ahead of Schedule

    Progress Energy Carolinas will shut down its 170-MW W.H. Weatherspoon coal-fired power plant this fall, several years ahead of the originally announced retirement schedule. The decision follows an evaluation of system resource needs.

  • Dominion to Switch Three Coal-Fired Plants to Biomass

    Dominion Virginia Power on Friday announced it would convert three 63-MW Virginia coal-fired peaking plants to biomass. The Dominion subsidiary said that while the switch would provide a boost to the local economy, it would also reduce nitrogen oxides, sulfur dioxide, mercury, and particulate emissions to “meet stringent new emission standards established by the U.S. Environmental Protection Agency.”

  • Federal Judge Ruling Poses Another Delay for Kansas Coal Plant

    Sunflower Electric Power Corp.’s proposed 895-MW Kansas coal-fired power plant suffered another legal setback last week as a federal district court judge ruled in a lawsuit filed on behalf of environmental group Sierra Club that the U.S. Department of Agriculture (USDA) violated federal law by providing approval and financial assistance to the project without environmental review and pubic involvement.

  • IEA: Coal Demand Eclipses Clean Energy Efforts

    The first Clean Energy Progress Report released today by the International Energy Agency (IEA) finds that while “impressive progress” has been made in developing clean energy technologies in recent years, demand for fossil fuels has continued to surge. Coal has met 47% of global new electricity demand over the past decade, “eclipsing clean energy efforts made over the same period of time,” the agency says.

  • DOE, DOI Make Hydropower Push with Funding, Potential Capacity Additions

    An internal study released by the Bureau of Reclamation on Thursday found that the federal body overseen by the Department of the Interior (DOI) could generate up to 1 million MWh more power annually from 70 of its existing facilities in 14 states. The report was followed by an $26.6 million funding announcement by the DOE and DOI on Tuesday for research and development projects to advance hydropower technology, including pumped storage.

  • Flawed Rules May Sink Small Calif. Renewable Projects

    In December 2010, the California Public Utilities Commission (CPUC) issued a decision with considerable fanfare that was intended to provide for the development of 1,000 MW of additional new renewable generation and provide California’s large investor-owned utilities (IOUs) with additional flexibility in complying with California’s Renewables Portfolio Standard (RPS) requirements. Unfortunately, it is likely to have the opposite effect.

  • Sendai Plant Boosts Efficiency and Cuts Emissions

    Located on the scenic Japanese coastline, Tohoku Electric Power Co., Inc.’s new 446-MW Sendai Thermal Power Station Unit 4 is a combined-cycle plant that replaces three 175-MW coal-fired units that had been in operation for more than 50 years. The new plant features the first application of MHI’s 50-Hz M701F4 gas turbine, which provides a thermal efficiency boost from the old plant’s 43% to more than 58%. This change substantially reduces CO2 emissions.

  • Energy Storage Enables Just-in-Time Generation

    One of the main criticisms of renewable energy facilities is that they are unable to dispatch electricity when it’s needed. The great game-changer is low-cost energy storage, which would enable renewable energy production to be stored and rapidly released when needed. Here are seven promising distributed energy storage technologies that could be commercialized in the near future.

  • Frisbees to Flatulence

    I recently outlined the top four regulatory obstacles facing existing U.S. coal-fired power plants in the coming years. That list, although not comprehensive, covered issues that owners of coal plants should be concerned about in the near term. However, in the long term, there is one regulatory development that dwarfs all others.

  • Changing Winds: The Evolving Wind Turbine

    As early as the first century A.D., wind energy was harnessed for practical purposes. Since then, turbine designs have come a long way from the archetypal post-mounted four-bladed devices. Today’s ubiquitous three-bladed designs will soon be evolving in many unexpected directions.

  • Australians Say "No" to Carbon Tax

    Australian prime minister Julia Gillard invited Jill Duggan, of the European Commission Directorate General of Climate Action and the UK government’s head of international emissions trading, to help bolster Gillard’s push for support of a carbon tax early in March. However, when interviewed on a morning show, Duggan was unable to estimate either the cost or the benefits of the UK’s program. In fact, the interview was a complete disaster.

  • The Smart Grid and Distributed Generation: Better Together

    Electricity grids are slowly getting smarter. Simultaneously, the use of distributed generation is increasing. Though smart grid advocates tout the ability of a smarter grid to enable greater deployment of distributed resources, the benefits could flow in both directions.

  • Condenser Performance Improvement Through Innovative Cleaning and Leak Detection Technologies

    One of the largest returns on investment a plant can achieve is the improved condenser performance that results from an effective condenser tube cleaning. Perhaps it is time to reevaluate your choice of cleaning technologies, establish an optimal cleaning schedule, and add routine air and water in-leakage surveys to your plant’s maintenance schedule.

  • Biomass Cofiring: A Promising New Generation Option

    Biomass cofiring has the potential to cut emissions from coal-fueled generation without substantially increasing costs or infrastructure investments. Research shows that when implemented at relatively low biomass-to-coal ratios, energy consumption, solid waste generation, and emissions are all reduced. However, mixing biomass and coal does create some challenges that must be addressed.

  • Respect Your Refractory

    Because refractory is out of sight inside the gas flow path of a steam generator and its auxiliaries, it’s also often out of mind. That is, until the refractory fails and causes a forced outage.

  • Fire Protection Options for Air-Cooled Hydroelectric Generators

    Fire protection systems for air-cooled hydroelectric generators have several special requirements due to these generators’ unique geometries. This survey of options will help plant owners and operators make the best equipment selections for their plants and thereby avoid unexpected surprises.

  • Power 101: Improving the Performance of Boiler Auxiliaries, Part III

    Efficient boiler operation requires boiler auxiliary equipment to operate in harmony. In this third and last installment of our Power 101 series, we examine ways to decrease the auxiliary power requirements of boiler auxiliaries.

  • Spanish Wind, Revisited

    Two years ago, Spain’s fixation on renewables and “green jobs” was praised by President Obama as a success story worthy of our emulation. How is Spain doing today?

  • Nuclear Fever Breaks

    Excitement over an expected nuclear renaissance reached fever pitch over the past decade. Today, the original volume of announced projects has been sifted, leaving just a few serious ones that may match well with the level of loan guarantees recently announced as part of the president’s budget proposal. The pace of progress is slow, yet progress is almost certainly unavoidable.

  • House Panel Hustles Through Bill Blocking EPA Climate Rules

    In an anti-climactic markup that featured little new debate and no amendments by opposing Democrats, the House Energy and Power Subcommittee approved Republican legislation to block Obama administration action on climate change by stripping the Environmental Protection Agency of its Clean Air Act authority to regulate carbon dioxide and other greenhouse gases.

  • The Battle to Control Quake-Stricken Japanese Reactors

    As POWER closes this issue (March 15), 6,000 people have been confirmed dead and 10,000 others are still missing as a result of the magnitude 9.0 earthquake and ensuing tsunami that destroyed Japan’s eastern shore on March 11. At this writing, the country is battling a third cataclysm—the potential meltdown of several reactors at Tokyo Electric Power Co. (TEPCO’s) Daiichi nuclear power plant in Fukushima Prefecture.

  • Benchmarking Fossil Plant Performance Measures, Part II: Fleet-Level Metrics

    Part II of this three-part series moves up the typical utility organization to consider important fleet-level fossil plant operating metrics. This portion of the EUCG-sponsored benchmarking survey found that utilities favor fleet-level metrics that are similar to plant-level metrics but assign them different priority. Utilities generally agreed on what were important metrics in the eight categories examined, although none were favored by a majority of the surveyed utilities.
