New turbine technologies offer unprecedented flexibility.
If there’s an electric power project under development that best reflects the current state of the U.S. gas turbine market, it might be the Northern California Power Agency’s (NCPA) 280-MW, natural gas-fired combined-cycle plant in Lodi, Calif.
Getting realistic about energy efficiency.
Is energy efficiency the answer to all our energy problems? The solution is more complicated than the hype would suggest. Only a practical approach can overcome barriers to capturing efficiency savings as a sustainable resource.
Why America’s bridge fuel faces a road block.
In 2009, unconventional shale gas emerged as the dominant driver in North American natural gas markets. Rapid increases in shale gas production and shale-driven upward revisions to the U.S. natural gas resource base have reversed the outlook for the U.S. natural gas supply. In contrast, the economic recession and growing uncertainties around the role of natural gas in power generation have clouded the outlook for natural gas demand. Natural gas has been called the “bridge fuel” for its potential to support the transition to a low carbon U.S. economy.
The most economical energy savings might be found in grid efficiency.
Power delivery efficiency gains constitute a valuable utility asset that can offset or defer new generation and T&D investments. Enabling technologies, utility demonstration projects and supporting regulatory frameworks are needed to validate potential savings.
Realizing the benefits of a modernized system requires an integrated strategy.
The U.S. power market consistently has displayed cyclical characteristics of boom and bust over the last two decades. Today’s market environment has been directly and significantly impacted by the recent economic recession. Decreases in load growth, declining commodity prices, and lack of accessible financing have caused challenges for the industry.
The black art of pricing social costs.
At the Power-Gen International trade show in December, Questar Chairman & CEO Keith Rattie delivered a firebrand speech opposing the prospect of CO2 cap-and-trade legislation. To summarize, he said the Waxman-Markey climate bill is an “asinine” piece of legislation—which it is, as anyone who reads it quickly discovers. But more broadly, he said concerns about greenhouse gases (GHG) are based on incomplete science and politically motivated alarmism.
Capture and storage tech developments secure coal’s future.
Capture and sequestration will help ensure the future of coal-fired power plants. Demonstration projects are allowing utilities to kick the tires on the latest technologies, and to learn how CCS will affect operations and economics at state-of-the-art plants.
How to manage the green revolution.
Dramatic changes are coming to the electric industry, sparked by a surge of renewable energy and related transmission. Growth in demand-side resources, conservation and smart technologies will add integration dilemmas to an already complex power system.
A tale of two energy worlds.
As federal policy makers push for GHG regulation and transparent markets, the California experience shows what works and what doesn’t work.
Carbon costs will reshape the generation fleet and affect retail rates.
American utility consumers face a compelling generational challenge: satisfy the need for a reliable power supply, at a reasonable price, while also reducing greenhouse-gas emissions and building a sustainable energy industry. How the government structures green-energy mandates will determine how long existing power plants remain viable.
