Aheat-recovery steam generator (HRSG) is much like other power generation equipment—run it at design conditions and chances are it will run with high availability and require only routine maintenance for

Power plants are, with good reason, almost universally regarded as fixed assets to be operated, maintained, and retired on the spot where they were built. The idea of relocating something as large and

The past week saw a flurry of Congressional hearings probing how the Environmental Protection Agency’s (EPA’s) proposed carbon pollution rules will affect grid reliability and the economy.  On Reliability  The U.S. House Energy and Commerce Committee on Tuesday summoned the Federal Energy Regulatory Commission’s (FERC’s) four sitting commissioners and future chair Norman Bay to testify on […]

Interest in the Environmental Protection Agency’s (EPA’s) carbon pollution standards for existing power plants—the “Clean Power Plan,” proposed under the authority of the Clean Air Act Section 111(d)—was so high that the agency had to add double the days and double the rooms at all four locations this week. At all locations, power industry speakers […]

Speaking at the Energy Innovation Symposium in Washington D.C. on July 23, Southern Co. CEO Tom Fanning said that he would love “to announce another nuclear plant” later this year. But Fanning made it clear during his keynote address to attendees at the Bipartisan Policy Center’s American Energy Innovation Council–sponsored event that he favors an […]

San Diego Gas & Electric (SDG&E) on July 21 formally requested permission from the California Public Utilities Commission (CPUC) to enter into a power purchase agreement (PPA) with NRG Energy for up to 633 MW from the proposed Carlsbad Energy Center. The move is what SDG&E and NRG hope is the last chapter in a […]

When GenOn Energy (now part of NRG Energy) announced in March 2012 that it would retire the 1950s-era coal-fired Shawville Generating Station in western Pennsylvania—blaming the impending Mercury and Air Toxics Standards (MATS)—the reaction was swift and bitter. “Pragmatic energy policies should not guillotine coal from the nation’s energy grid,” then-state Rep. Bud George, who […]

Rep. Fred Upton (R-Mich.), chairman of the House Energy and Commerce Committee, on Tuesday unveiled five pillars on which U.S. energy policy should be built and discussed how the nation should tackle climate risks and grid threats.  The lawmaker told attendees at the Energy Information Administration (EIA) 2014 Energy Conference that the nation’s new era […]

Optimism about U.S. energy security, which is rooted in the abundant supply of fossil fuels alone, is misplaced, Maria van der Hoeven, head of the International Energy Agency (IEA) told attendees at an energy conference in Washington, D.C., on Monday.  The U.S. has seen a dramatic reversal in its energy fortunes over the past seven […]

After bottoming out at 822 billion cubic feet (Bcf) the week ending Mar. 28—the lowest level since April 2003—U.S. inventories of natural gas in underground storage have risen sharply this summer, though levels remain below recent averages, according to Energy Information Administration (EIA) data. Following a severe winter in which the country burned through a […]

Under rules proposed by the Environmental Protection Agency (EPA) on June 2, 2014, existing fossil fuel–fired U.S. power plants must comply with state-specific goals to lower carbon pollution from the power sector by 2030, while modified and reconstructed power plants will be subject to technology-based performance standards. The EPA’s “Clean Power Plan” rule affecting existing […]

RWE AG is Europe’s third-largest electricity and fifth-largest gas marketer, with holdings in upstream oil and gas production, power grids, and energy trading. Its German power subsidiary has been the utility poster child for the effects of the Energiewende, the transformation of the Germany power system away from nuclear and coal toward renewable energy and […]

At the Edison Electric Institute (EEI) annual meeting this week in Las Vegas, the tone was one of collaboration with partners from Washington to distributed generation companies. Those partnerships will be needed as the investor-owned utility (IOU) industry fights not so much a war on coal as a war for mindshare and wallet share in […]

Florida Power & Light (FPL), Florida’s largest utility, announced on June 25 that it was looking to invest directly in natural gas exploration and production as a means of securing future gas supplies and guarding against price volatility. NextEra Energy subsidiary FPL, the largest consumer of gas in the state, has been rapidly expanding its […]

The U.S. House of Representatives on Wednesday voted 266–150 to pass a bill that cuts federal red tape and accelerates liquefied natural gas (LNG) exports to Europe and other allies. The Domestic Prosperity and Global Freedom Act (H.R. 6) authored by Rep. Cory Gardner (R-Colo.) now moves to the Senate. Experts suggest it has a […]

This week, the Bonn climate change conference concluded in Germany. During the talks, discussion focused on adaptation and long-term greenhouse gas emissions reduction goals to meet climate targets. These mitigation and adaptation strategies build on international momentum to tackle climate change, such as China’s announcement that by 2016, its first carbon emissions cap will come […]

Most issues concerning resource adequacy have arisen in the context of restructured wholesale and retail electric markets, rather than from traditionally regulated electric markets, a new study from the Electric Markets Research Foundation (EMRF) suggests.  The nonprofit EMRF,  established in 2012 by “academics and other experts” to fund studies on electric market issues, notes in […]

The U.S. Environmental Protection Agency (EPA) is considering the imposition of nationwide reporting requirements for chemicals and mixtures used in fracking operations. On May 19, 2014, the EPA published an Advanced Notice of proposed rulemaking in the Federal Register seeking public input on the development of such a rule, including whether reporting should be mandatory […]

Existing fossil fuel–fired U.S. power plants must comply with state-specific goals to lower carbon pollution by 2030 under rules proposed by the Environmental Protection Agency (EPA) today. The so-called “Clean Power Plan,” which applies to existing power plants, seeks to cut carbon emissions from the power sector by 30% from 2005 levels by 2030. It […]

South Africa’s critical power situation has been the subject of much talk and speculation since 2008, when the country experienced its first electricity crisis after enjoying a surplus of cheap electrcity since the 1980’s. Download the report.

After two years of work, about a dozen conferences and meetings, and multiple rounds of comments, the Federal Energy Regulatory Commission (FERC) announced on Mar. 20 that it was ready to begin the process of

With the growing need for operational flexibility across the power industry, the combined-cycle gas turbine (CCGT) fleet is increasingly being subjected to load-following and cyclic operation. This change in

There is no hotter market in power generation than gas. According to the Energy Information Administration (EIA), the U.S. is projected to add just under 60 GW of new generating capacity between 2013 and 2017

With the gas-fired power sector in continual flux, blessed by plentiful gas supplies but faced with uncertain fuel costs and competition from intermittent renewable generation, plant owners must make

According to a report released on May 28, NOX and SO2 emissions in 2012 were 74% and 79% lower, respectively, than they were in 1990 when Congress passed major amendments to the Clean Air Act. Although power plant CO2 emissions have actually increased 13% from 1990 levels, the trend has been down in recent years, […]

A final rule establishing national technology-based effluent limitations guidelines and standards to reduce discharges of pollutants from nuclear and fossil fuel power plants to U.S. waters won’t be issued until at least September 2015, the Environmental Protection Agency (EPA) has confirmed.  This April, the agency and environmental groups Defenders of Wildlife and the Sierra Club […]

Substantial new gas-fired and solar generation that have been added to the California grid over the past year are expected to take up the slack this summer as an ongoing severe drought has led to substantial limitations on hydroelectric generation, according the summer 2014 assessment from the California Independent System Operator (CAISO). According to the […]

Rebounding from the loss of the Crystal River nuclear plant, Duke Energy Florida announced plans on May 13 to replace the lost capacity with a new 1,640-MW combined cycle plant on the same site.
