In 2010, the 2,310-MW Adapazari Power Plant achieved 99.8% availability, which is nearly 7% higher than the industry average and a global record in F-class gas turbine technology. The new turbine upgrade is helping ENKA Power bolster Turkey’s evolving economy by improving its energy sector’s efficiency and productivity.
A brush fire that spread and detonated explosives stored at the Evangelos Florakis naval base in Mari on the southern coast of Cyprus on July 11 killed 13 people, injured 62 others, and severely damaged the Vassilikos Power Station—an oil- and gas-fired plant that supplied almost 60% of the island nation’s power. Cyprus, which was once considered an “economic miracle,” has been battling crippling power shortages that have beleaguered its financial and tourism sectors since the blast and left it on the verge of economic collapse.
A web supplement to the September issue with details of global power shortages.
Heat waves, droughts, and other weather and climate phenomena; economic woes; aging or inadequate infrastructure; fuel shortages. These are some of the most obvious causes that have led to record peaks in power demand or sudden drops in available capacity. The results have been sometimes debilitating load-shedding, brownouts, and blackouts around the globe this summer (and, in some cases, for much longer). Here’s an overview of which countries are affected by which difficulties. For a more detailed look at the extent of shortages and what’s causing them, visit Web Exclusives at http://www.powermag.com
The major economic hurdle for renewable power generation technologies continues to be substantial installation costs. But another cost is associated with continuous load-balancing, made possible by backstopping that variable generation with dispatchable generators that typically consume expensive fossil fuels. Bottom line: Who pays for the capacity firming or backstopping resources?
As barriers to new coal-fired generation expand and enthusiasm for nuclear plants wanes, the commissioning of natural gas–fired plants promises to increase. However, gas plants pose hazards, too. An explosion last year that was caused by unsafe use of natural gas to blow residue from a gas pipeline during commissioning of a gas-fired power plant has focused regulator and industry attention on finding safer alternatives for this task. Fluor shares its gas pipeline cleaning best practices.
Marcellus Shale gas has increased recoverable natural gas reserves in the U.S. by about a third over estimates prepared a few years ago. Europe is also exploring shale gas as an alternative to problematic Russian gas supplies and low proven natural gas reserves. POWER contributors in the U.S. and UK examine the comparative economic value, public acceptance, and political implications of these massive shale gas reserves.
The 435-MW Montoir-de-Bretagne gas-fired power plant is ramping up Gallic generation in the Loire-Atlantique region of western France. The plant’s innovative natural gas combined cycle technology offers high efficiency and low emissions.
The Irsching 4 Combined Cycle Power Plant has set a new world record in power plant efficiency with its new SGT5-8000H gas turbine. With an output of more than 578 MW and efficiency of 60.75% (net) achieved at a world record test run in May 2011, the plant demonstrates that climate protection, low-cost power generation, and flexible operation using fossil fuels can be attained simultaneously through technical advances. Due to its high efficiency, the gas-fired plant uses significantly less fuel and produces lower carbon dioxide emissions than traditional combined cycle plants.
The new 2,100-MW Phase 1 EMAL combined cycle power plant provides dedicated power with a high level of reliability to the Emirates Aluminum Smelter Complex, which is designed to be the world’s largest aluminum smelter upon completion. Located on the Persian Gulf, the gas-fired combined cycle plant uses seawater cooling towers to eliminate thermal stress on local marine life.
