Brazil’s electricity market is vast: the largest in Latin America and 10th largest in the world, with an installed capacity of 121,000 MW. Download the report.

The U.S. Environmental Protection Agency’s Mercury and Air Toxics Standards (MATS) set limits on the emissions of mercury (Hg) and other pollutants for coal-fired power plants. Many plant operators have

The history of power plant emissions regulations and control technologies is largely one of preventing elements that are bad for the environment or human health—including sulfur dioxide, particulate matter

A little over five years ago, on the night of Dec. 22, 2008, the residents of Kingston, Tenn., were devastated when a dike holding back an 84-acre ash pond broke loose. The ash pond servicing Tennessee Valley

Increasing Environmental Protection Agency (EPA) restrictions pertaining to emissions from coal-fired power plants, the increasing cost of coal operations, and the decreasing cost of natural gas provide strong

Mitsubishi Heavy Industries Ltd. (MHI) and Southern Co. have completed the initial demonstration phase of a carbon capture and storage (CCS) test at the Plant Barry power station in Mobile, Ala. The companies

The increasing penetration of intermittent renewable generation, smart grids, demand response, and other emerging technologies has underscored the need for power plants with greater flexibility and

This is the story of a power plant like no other. The facility runs primarily on coal, but it can utilize petcoke and biomass when available. The front end resembles an integrated gasification combined cycle

The aftermath of two spills from a coal ash storage pond at Duke Energy’s Dan River Steam Station in North Carolina this month, which saw about 35,000 tons of ash flood into the Dan River, may lead to a crackdown by North Carolina state regulators and will likely affect the Environmental Protection Agency’s (EPA’s) decision-making […]

Federal judge Walter S. Smith, Jr. ruled on Feb. 26 that Luminant had not violated the Clean Air Act (CAA) at its Big Brown Power Plant in Freestone County, Tex., as had been claimed in a Sierra Club lawsuit. Filed in May 2012, the lawsuit alleged that from July 2007 to the present certain emissions […]

A plan developed by Oklahoma to address regional haze that was approved by the Environmental Protection Agency (EPA) last week will force Public Service Co. of Oklahoma (PSO) to shutter two coal units by 2026. The agency on Feb. 10 approved Oklahoma’s state implementation plan (SIP) to control regional haze from two coal units owned […]

The Environmental Protection Agency (EPA) is seeking comment on its interpretation of provisions in the Energy Policy Act of 2005 (EPACT 2005), which it claims do not alter the agency’s determination that the best system to reduce carbon emissions for new coal and gas-fired power plants is partial carbon capture and storage (CCS).  The issue […]

The Environmental Protection Agency (EPA) last week proposed to approve revisions to a Texas state plan to regulate greenhouse gas (GHG) emissions in the state. If finalized, likely later this year, the EPA will rescind its Federal Implementation Plan (FIP) that is currently in place and grant the state GHG permitting authority.  According to the […]

The Environmental Protection Agency (EPA) reported on Feb. 4 that total releases of toxic chemicals decreased 12%, while toxic air releases were down 8% in its annual Toxics Release Inventory (TRI) report. The data—from 2012—was compiled from 21,024 facilities that are required to report to TRI. Of that total, only 582 of the facilities fall […]

[Update Feb. 10] Duke Energy workers have succeeded in permanently stopping the leak from its coal ash pond at the Dan River Steam Station, the company reported on Feb. 8. A storm drain under the pond broke on Feb. 2, releasing coal ash and contaminated water into the Dan River. The leak was not plugged […]

Power produced by South Africa represents 40% of Africa’s total—yet that country is facing a crippling supply shortfall. Emergencies are offset with imports from its neighbors in southern Africa, some of which are electricity poor, and others that are latent supply giants. “Power Africa,” the recently announced U.S. initiative that earmarks $7 billion in public […]

It seems as if each week brings further bad news for coal power plants. Recently, Consumer’s Energy sought relief to close three power plants, South Carolina Electric & Gas announced it would cease

The UK’s faltering plans to establish a carbon capture and storage (CCS) industry by the 2020s got a renewed boost in December as the government pledged to back the Drax Group’s White Rose project

The Mercury and Air Toxics Standards (MATS), promulgated by the Environmental Protection Agency (EPA) on Dec. 21, 2011, set maximum achievable control technology (MACT) emission standards for specific classes

Fire protection for power plant turbine rooms has typically been a game of tradeoffs. Enclosure integrity issues in older facilities can render CO2 and halon systems ineffective. In new and old facilities

Roughly five years ago, the power industry readily embraced the new Alloy 2205 metal as a more lightweight and cost-effective substrate for the construction of flue gas desulfurization (FGD) absorbers and

In power plants with drum-type boilers and constant-speed main boiler feed pumps, the feedwater control valve (also referred to as the drum level control valve) provides the means for controlling flow to the

On Feb. 2, 2011, a winter storm gripped the Lone Star State, bringing freezing temperatures and heavy ice loads onto the state’s electric infrastructure. Texas experienced a series of unexpected rolling

Oklahoma has asked the U.S. Supreme Court to review a lawsuit that challenges the Environmental Protection Agency’s (EPA’s) authority to reject a state regional haze plan and replace it with a federal implementation plan (FIP). Last July, in a 2–1 decision, the U.S. Court of Appeals for the 10th Circuit upheld the EPA’s rejection of […]

The Environmental Protection Agency (EPA) must issue a proposed revision of its Resource Conservation and Recovery Act (RCRA) Subtitle D rules regulating coal combustion residuals no later than Dec. 19, 2014, under a consent decree reached between the agency and environmental groups that was filed in federal court today.  The U.S. District Court for the District of Columbia […]

President Obama spoke briefly about energy in his State of the Union address on Tuesday night, though he declared at the outset: “The all-of-the-above energy strategy I announced a few years ago is working, and today, America is closer to energy independence than we’ve been in decades.” That statement rejected recently expressed concerns from 18 […]

Big Rivers Electric Corp.—a member-owned, not-for-profit, generation and transmission cooperative serving western Kentucky—plans to idle two of its coal-fired power plants following the loss of its largest industrial load. The D.B. Wilson Station, a 417-MW plant located in Centertown, Ky., will idle on Feb. 1, barring a miracle. Big Rivers simply doesn’t need the power […]

The European Union (EU) should emit 40% less carbon dioxide than it did in 1990 and produce 27% of its energy from renewables by 2030, declares a new framework on climate and energy presented by the European Commission (EC) on Wednesday.  The communication setting out the 2030 framework is now expected to be debated by the […]

 The Environmental Protection Agency’s (EPA’s) proposed New Source Performance Standards (NSPS) for greenhouse gas (GHG) emissions from new power plants violates the Energy Policy Act (EPACT) of 2005, a suit filed in federal court by the state of Nebraska alleges.  The state alleges, as have a number of Republican lawmakers, that the EPA relied on […]
