  • EU Ruling Slackens Poland’s Coal Power Expansion Ambitions

    Poland, a country that currently depends on coal power for nearly 85% of its electricity and plans to build another 11,300 MW of new coal-fired capacity by 2020, suffered a critical planning setback in mid-July as the European Union (EU) effectively blocked the country from using free carbon emission permits to build new coal-fired power plants.

  • Partners in Reliability: Gas and Electricity

    The natural gas and electricity industries have entered into an increasingly codependent relationship as coal-fired electricity gives way to natural gas–fired generation. Both industries are firmly committed to providing reliable service, although each goes about its business in different ways. Utilities, regulators, and stakeholders are searching for ways to align interests and expectations.

    An innovative mini-grid in April turned on the lights for about 250 residents living in Ilha Grande, a tiny island on the northwest coast of Maranhão State in northeastern Brazil.

  • O&M and Human Stresses Caused by Low Gas Prices

    Plentiful supplies of low-cost natural gas have changed unit dispatch orders across the U.S., led to thermal stress–induced maintenance issues at cycling coal plants, and resulted in management challenges at coal and gas units alike. This scenario is unlikely to change so long as gas holds its competitive edge over coal.

  • Too Dumb to Meter, Part 3

    As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the third chapter, “Micro-Mismanagement by Committee.” During the frenzy to manage atomic power after World War II, Congress created an executive branch agency that threatened to be too independent, too powerful, and too isolated from the rest of government. Compounding their errors, perhaps in recognition of what they had created, the solons also developed a way to insert their own power into the action. This proved to be a major mistake—blurring the lines between executive and legislative authority—causing no end of problems for the nation’s nascent atomic energy venture.
