Entergy Corp. announced on Monday that it plans to continue operating its 2,000-MW Indian Point nuclear power plant in spite of the N.Y. Department of Environmental Conservation’s (DEC) rejection of the plant’s application for a water quality certification on Friday.

The Texas Public Utility Commission (PUC) announced on Thursday its plan to carry out a multi-pronged evaluation process for the independent testing of smart meters installed in the Texas competitive retail electric market. This action follows Oncor Electric Delivery’s announcement last week that it had incorrectly installed more than a thousand smart meters in central Texas.

Xcel Energy and Calpine Corp. announced on Monday that Public Service Company of Colorado, an Xcel Energy company, will purchase two of Calpine’s power plants near Denver that currently provide power to the utility under power purchase agreements.

Entergy Corp., the second-largest operator of nuclear power plants in the U.S., announced on Monday it will cancel its proposed spin-off transaction that would have relocated six of its nuclear units into newly formed companies, Enexus Energy Corp. and EquaGen LLC. This decision occurred in the wake of the New York Public Service Commission’s (NYPSC) decision on Thursday to reject the company’s planned spin-off.

Suniva, a U.S. manufacturer of high-efficiency monocrystalline silicon solar cells and modules, announced on Thursday that it has been selected for the U.S. Department of Energy (DOE) Loan Guarantee Program under the DOE’s Innovative Energy Efficiency, Renewable Energy and Advanced Transmission and Distribution Technologies Solicitation.

Portland General Electric (PGE) said on Friday it had submitted a proposal to Oregon’s Department of Environmental Quality (DEQ) to close its coal-fired Boardman Power Plant by 2020.

Florida Power & Light Co. (FPL) said on March 31 that meeting state-mandated energy conservation goals could cost the typical 1,000-kilowatt-hour customer an additional $2 to $3 a month.

Greensburg was destroyed by an EF5 tornado on May 4, 2007. Instead of abandoning the Kansas town, the community quickly embraced the task of rebuilding it from the ground up, maximizing the use of renewable energy sources and energy efficient building techniques. Rebuilding continues, but the future of Greensburg has never been stronger.

In response to Ontario’s provincial regulatory mandates to phase out the use of coal by the end of 2014, Ontario Power Generation (OPG) is exploring its capability to employ biomass feedstocks to displace coal in some units within the OPG thermal fleet. The primary fuels employed during the respective trials at its Nanticoke and Atikokan Generating Stations have been agricultural by-products and commercial grade wood pellets. The Canadian utility has learned valuable lessons about fuel supply and logistics, and the technical challenges of safely handling and firing high levels of biomass.

President Barack Obama’s January State of the Union speech called for incentives to make clean energy profitable — mainly through the construction of a new generation of nuclear power plants. That comment, an apparent effort to reach out to Republican members of Congress, drew furious applause. Within three weeks, the president’s backing of nuclear power had already made a significant impact on the U.S. nuclear sector.

The EUCG Nuclear Committee has collected benchmarking data of U.S. nuclear plant staffing for many years. A summary of this highly desirable data was gleaned from EUCG databases and is now, for the first time, made public through an exclusive agreement with POWER.

Scientists at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) in California speculate that a prototype nuclear fusion power plant could be operational within a decade, thanks to a test of the world’s largest laser array that confirmed a technique called inertial fusion ignition is feasible. Their first experiments have demonstrated a unique physics effect that bodes well for NIF’s success in generating a self-sustaining nuclear fusion reaction. Fusion energy is what powers the sun and stars.

The power industry needs a straightforward definition of "fleet optimization" and a game plan to achieve the promised economic gains of optimizing. This need has become more urgent because integrating nondispatchable renewable resources requires more complex optimization strategies. The bottom-up approach presented here applies well-understood optimization principles and techniques that will help power producers minimize their fleetwide cost of production, independent of the technologies used to generate electricity.

Could the transformation of carbon dioxide (CO₂) into carbonates and oxides solve the problem of greenhouse gas emissions (GHG) from fossil-fired power plants? Some companies are betting that such processes could make everyone happy and even create new profits. Buzz has been growing about this approach, though the concept has been around for many years.

A good default proposition regarding the government’s role in the economy would state that the government should not loan money to an enterprise if the enterprise in question cannot find one single market actor anywhere in the universe to loan said enterprise a single red cent. It might suggest—I don’t know—that the investment is rather … dubious.

Enhanced condenser tube designs can significantly improve the heat rate and performance of fossil and nuclear plants. Using the optimum number of tubes and replacement tube sheets will cost more than simply replacing plain tubes. However, the investment’s simple payback is measured in only weeks, which builds a strong case for using an enhanced tube design as part of your next condenser overhaul.

Ocean Power Technologies Inc. (OPT) announced on Feb. 1 that it had successfully deployed one of its PowerBuoy wave energy devices about a mile offshore from a U.S. Marine Corps Base on the island of Oahu in Hawaii. The device generates up to 40 kW of power from the rise and fall of waves, and since its deployment in December 2009, it has been generating power within specifications.

In December 2009, representatives of nearly 200 governments met in Copenhagen, Denmark, to hammer out the details of a new climate change treaty. Treaty drafts indicated that industrialized countries would be required to reduce their greenhouse gas emissions—primarily carbon dioxide (CO2)—up to 80% by 2050. Developing countries would not be required to reduce emissions much, […]

River deltas experience extreme seasonal changes in water quality that perplex conventional water treatment systems. Industrial development in China, including new power plants, has spurred the development of desalination processes that have tamed these brackish water sources to provide a virtually unlimited supply of boiler-quality water.

In mid-February, the Geological Society of London raised the hopes of those promoting geothermal energy when results of exploratory drilling in Weardale, County Durham, revealed record levels of permeability in granite. Although the results are promising for the development of geothermal energy, they may have less welcome implications for the safe disposal of radioactive waste in deep repositories.

One of the primary challenges of reliably burning coal is managing the corrosion experienced by the furnace heat transfer surfaces. Fireside corrosion remains a leading cause of failure in superheater and reheater tubes. Three case studies examine the different failure modes experienced by tubes located throughout the furnace.

How much will a smart grid cost? It’s a question that has gained importance in light of massive cost overruns for one highly touted U.S. project.

In late January, a 1.5-MW concentrating solar power (CSP) plant began providing power to Salt River Project customers in Greater Phoenix, Ariz. Though small, the plant, developed by Tessera Solar and Stirling Energy Systems (SES), is seen as a prelude to 1,500-MW projects that are due to break ground in California and Texas later this year.

Every power engineer must have a firm grasp of the rudiments of how fuel is processed to produce electricity in a power generation facility. With this article, we begin a series of Power 101 tutorials that present these fundamentals in a clear and concise way. First up are the essentials of recovering heat from flue gas.

During a recent meeting of state utility commissioners, the CEO of a Fortune 500 electric power company said natural gas prices promise reliability but "always break your heart." What breaks my heart is the electric power industry’s ongoing love affair with natural gas. Using natural gas for generating electricity is not the best or highest use for this clean, green, and domestically abundant resource.

The "combined" portion of a combined-cycle plant is the heat-recovery steam generator (HRSG) that generates high-pressure and high-temperature steam and the steam turbine generator that expands the steam to produce electricity. Integrating the HRSG and steam turbine with the combustion turbine is a key challenge for plant designers, as each system has differing operating profiles, operational constraints, and design requirements.

While the Environmental Protection Agency appears to have initially proposed to regulate power plant coal ash as hazardous waste, there are indications the Obama administration is preparing new federal rules that will at a minimum require utilities to convert coal ash impoundments from wet to dry storage to prevent leaks—a change that would cost tens of millions of dollars but also potentially increase regulated utilities’ rate base and earnings, a Wall Street firm says.

CAT PUMPS recently introduced two new stainless steel triplex plunger pumps featuring a 316 stainless steel liquid-end for corrosion resistance. The 7CP6111 and 7CP6171 are designed for pumping liquids like seawater in small seawater reverse osmosis installations, demineralized water for misting, or hot water and sanitizers for sterile cleaning systems. The 7CP stainless steel pumps […]

Highlighting a sharp division within the public power community, two senior House Democrats blasted the American Public Power Association for endorsing Sen. Lisa Murkowski’s effort to strip the Environmental Protection Agency of its Clean Air Act authority to regulate greenhouse gas emissions, with the lawmakers saying they have been informed that “numerous” APPA members oppose the endorsement.
